Tank Bred vs. Captive Bred vs. Wild Caught

Some of you are new to seahorses, and you may be wondering, "What's the difference?" These terms may seem a little confusing and misleading to you, and trust me, they are not misleading by accident.

A Captive Bred, or CB for short, seahorse has been bred in captivity using synthetic seawater in enclosed, sterile systems. These seahorses have proven extremely hardy, easy to breed, and long-lived. They are trained to eat frozen mysis shrimp before sale, which makes them easy to feed. An excellent alternative to Wild Caught.

A Wild Caught seahorse has been caught in the wild. CITES has limited the distribution of WC seahorses, so you probably won't see them around much. History has shown that these seahorses are difficult to keep in captivity. They often never eat frozen foods, and must be provided with live foods for life. They most often come with parasites and other diseases that are difficult or impossible to treat, even prophylactically.

Now, when we get to tank raised/maricultured/tank bred/net pen raised seahorses, things are a little different. You might be saying, "But isn't it a good thing to buy Tank Raised?"

I STRONGLY BELIEVE THAT TANK RAISED, MARICULTURED, TANK BRED, AND NET-PEN RAISED SEAHORSES ARE THE NUMBER ONE THREAT TO THE SEAHORSE HOBBY.

Let me explain the history behind it.

Net pen raising is the brain child Amanda Vincent, self-proclaimed seahorse expert. It was invented to give poor people an alternative to catching them in the wild. Instead, they catch the juveniles, raise them in net pens in the ocean where the seahorses eat natural foods in their natural environments. Most of the net pen raised seahorses bred every year go on to be sold in the Traditional Chinese Medicine trade. Literally Tons, thousands and thousands of pounds. As an afterthought, many breeders started to sell their excess to US, the Aquarium trade.

Most often, it is done like this--When the breeder is done harvesting for the TCM trade, their excess is often put into bare bottom tanks flushed constantly with natural sea water. The seahorses are packed in like sardines. They finish "growing them out" here, thus allowing them to be called "tank raised." They are fed frozen foods, but not what I would call "trained." Basically, any seahorses that refuse to eat the frozen foods die, and are carted off to be sold to TCM. The ones that survive are then sold to us in the aquarium trade. These resulting seahorses are often loaded with parasitic and bacterial infections like Vibrio, even webbing. They are like little ticking time-bombs. Many of these infections are highly contagious to other syngnathids (including your pipefish) and incurable, even with prophylactic treatment. Even expert seahorse keepers who are capable of raising fry have had bad luck with these "tank raised" seahorses.

Now, some problems with this system--breeding a seahorse using natural seawater and mostly natural foods from the ocean is really cheap. The cost is next to zero. That makes net-pen raised seahorses very inexpensive. Legitimate captive breeding costs money. The salt, the food, it all adds up. Most seahorse breeders charge from $50-$100 per seahorse, and they never take home a paycheck. The most commonly "tank bred" or net pen raised seahorses are H. kelloggi and H. kuda. These species are not always native to the areas where they are being net pen raised. This means that some hybrids have been reported. Hybrids making it into the trade, and hybrids in the wild. Also, it's difficult to quantify exactly how much waste and pollution is produced by this method of breeding tons and tons of seahorses. But I can assure you, it is not minimal.

Back to the money issue. In the past year, most of the legitimate captive breeding facilities have closed down. Draco Marine just stopped production, they are shipping their last order this week. Poor Jorge could never bring home a paycheck. There are only a couple left, NYseahorse and Dan U. from seahorsesource in Florida. Neither have much in stock right now. There is still Ocean Rider in HI, but that's only if you want to pay $150 up to $999 for a single seahorse.

Right now, the most common species being tank raised are kuda and kelloggi. As far as I know, no one is breeding kelloggis in synthetic sea water. Maybe a couple kudas. Unfortunately, not much is known about kelloggi seahorses, except how to mass produce them. Being a deep-water seahorse, it is speculated that they may prefer temperatures even lower than where most people keep their seahorses at 74*. They have a horrible track record in captivity. Most only live for a few months. The ones that do last a year or two are the lucky ones, and that's a significantly short life span for that type of seahorse.

There are so many other species out there, why buy TR and limit your options? The most commonly Captive Bred seahorse is H. erectus. they are also the hardiest and most prolific, some say the most beautiful. As far as I know, they are not available TR. But there are so many other options, or at least, there used to be. At the very least, 10 or 15 different species are bred in captivity, but not available as net-pen raised or tank raised. Why? because the main purpose of net pen raising is not for us, the aquarists. It's for the TCM!

So next time you go into your LFS and you see a H. kelloggi or worse, Hippocampus sp. or "yellow seahorse," please pass on it. You'll be saving yourself some heartache. Educate your LFS and even your favorite online vendors. Tell them that you demand legitimate Captive Bred seahorses. Be cautious and do your homework. Some vendors and retailers are sneaky about it. Even ORA is importing TR seahorses (their kuda are net-pen raised)! Educate other beginning seahorse hobbyists. There is no other way to save this wonderful seahorse hobby.

I have made a promise to myself, and to the seahorse hobby, to never buy a tank bred seahorse. I will only buy from a legitimate captive breeding facility that uses synthetic seawater, bare bottom tanks, and frozen mysis. Join me, and make the promise. IF WE DON'T STOP BUYING TANK RAISED SEAHORSES, SOON WE WON'T HAVE A CHOICE!

I agree, awesome explanation.

My horse's came from Jorge at Draco Marine. I am very disheartened that he has had to close up shop. The good breeder's are all being undercut but the asian pen bred market. It is a sad time for the hobby, and the future of seahorses in general.

I could be wrong about some of this stuff, anyone care to add or correct anything? I want this to be as accurate as possible. I'd like some help on refining it and getting some good, solid references. I remember seeing some photos last year of one of those Asian Tank-rearing facilities. Anyone remember where those pictures went?!

Ann, you are a wealth of information, and better than I am at explaining things. I remember you found an interview with A. Vincent on PBS.com. Feel free to add your thoughts

Oh, I didn't find the interview, I'm too lazy for that I just referred to the whole seahorse documentary she was in and someone else dug up the quote from the interview. What you had to say was pretty spot on though, except the part about Reidi being the ORA sh from Sri Lanka, not Kuda, but you caught that yourself and corrected it.
The only other thing I saw was that you said there were at least 10 speceis being CB that weren't being NPR (net pen raised)... I can only come up with these:
Abdominalis, Barbouri, Breviceps, Capensis, Erectus, Tubers, Whitei, and Zosterae...
I am fairly certain that Reidi, "Kuda", "Kelloggi", Ingens, and possibly Comes are being NPR. Reidi, Ingens, and Comes can also be found CB from aquaculturists and hobbyists, and it looks like Kuda will be available CB shortly again as well.

Also, a clarification on the whole A.Vincent/Project Seahorse involvement in net pen raising:
There are island communities that are dependent upon the income that they receive from catching and selling seahorses to TCM. We cannot yank that income away, they would starve or do it anyway... so PS decided to "fix" it so that they collect the seahorses and "sell" them to PS instead of TCM. PS gives them a loan in the amount that they would have earned selling them to TCM. Then the islanders put the seahorses in pens in the ocean and "care" for them until they have grown larger (and theoretically reproduced, sending fry out into the ocean). These larger seahorses are then harvested and sold to TCM and/or the ornamental fish trade for higher prices since the seahorses are bigger, and the islanders use the procedes of the sale to pay off the loan from PS and pocket the rest. Several problems with this include:
1. other people steal seahorses from these pens in the ocean - its easy, they are all grouped tightly together and are already caught.
2. when non-native species like Reidi and Ingens are kept in these pens (which was not the "plan", but which does happen), you are introducing non-native species to the environment, both in terms of the fry that are released into the open ocean, and in terms of the bacteria that the seahorses bring with them that can cause big problems in the native syngnathid populations. Anyone hear about how "evil" caulerpa is in California, or how terrible the mariculture salmon can be on the natural environment... seahorses are just cuter than caulerpa and salmon
3. these seahorses are not being captive bred, or even tank raised. the more proper term would be "captive raised" and even that is a stretch; they are "trained to frozen" in various ways including what Molly said above, but by and large they are WC, and worse off for having been raised in close quarters with lots of other syngnathids and in many cases outside of their natural environment. In the case of Kelloggi, not only are they outside their natural range, but also their natural depth (i.e., wrong temperature, wrong water pressure, wrong lighting, etc.). Stressed fish are not healthy fish.

Anything else you were thinking of?

Wow, thanks, Ann!

I'm not trying to shut down any net-pen raising operations. I just don't want those SH in our hobby. They don't belong here. They are raised for consumption.

Some of you are new to seahorses, and you may be wondering, "What's the difference?" These terms may seem a little confusing and misleading to you, and trust me, they are not misleading by accident.

A Captive Bred, or CB for short, seahorse has been bred in captivity using thoroughly filtered, sterilized or synthetic seawater in enclosed, sterile systems. They are kept apart from other syngnathids to prevent spread of disease. These seahorses have proven extremely hardy, easy to breed, and long-lived. They are trained to eat frozen mysis shrimp before sale, which makes them easy to feed. An excellent alternative to Wild Caught.

A Wild Caught seahorse has been caught in the wild. CITES has limited the distribution of WC seahorses, so you probably won't see them around much. History has shown that these seahorses are difficult to keep in captivity. They may never eat frozen foods, and must be provided with live foods for life. They most often come with parasites and other diseases that are difficult or impossible to treat, even prophylactically.

Now, when we get to tank raised/maricultured/tank bred/net pen raised seahorses, things are a little different. You might be saying, "But isn't it a good thing to buy Tank Raised?"

I STRONGLY BELIEVE THAT TANK RAISED, MARICULTURED, TANK BRED, AND NET-PEN RAISED SEAHORSES ARE THE NUMBER ONE THREAT TO THE SEAHORSE HOBBY.

Let me explain the history behind net-pen raising seahorses.

Net pen raising seahorses is the brain child of seahorse biologist Amanda Vincent. Please see "Kingdom of the seahorse" by NOVA starring Amanda Vincent. It was invented to give poor people an alternative to catching them in the wild. Dr. Vincent said that she understands that we can't save individual seahorses, but with this method, we can save the species. She also states that the aquarium trade is a threat to wild populations of seahorses. When she posed as a breeder and asked Chinese market owners how many seahorses they would buy from her if she could supply, they answered, "Tons...unlimited supply."

On a side note, when asked why they consume seahorses for TCM, they said that they are an aphrodisiac because seahorses mate for life. Someone should tell them what promiscuous little creatures seahorses really are. They don't mate for life.

Net-pen raising was intended to help poor villagers and save native seahorses. They caught pregnant males and adults native to the area, keeping them in pens where the seahorses ate natural foods. Today, however, net-pen raising has become big business overseas. The most commonly net-pen raised seahorse is H. kellogi, which is not native to all of the countries where it is being cultured. Most of the net pen raised seahorses bred every year go on to be sold in the Traditional Chinese Medicine trade where they are worth more than their weight in silver. Literally Tons, thousands and thousands of pounds. As an afterthought, many breeders started to sell their excess to US, the Aquarium trade.

Most often, it is done like this--When the breeder is done harvesting for the TCM trade, their excess is often put into bare bottom tanks flushed constantly with natural sea water with minimal or no filtration. The seahorses are packed in like sardines. They finish "growing them out" here, thus allowing them to be called "tank raised." They are fed frozen foods, but not what I would call "trained." Basically, any seahorses that refuse to eat the frozen foods die, and are carted off to be sold to TCM. The ones that survive are then sold to us in the aquarium trade. The methods vary, but the result is the same.

These resulting seahorses are often loaded with parasitic and bacterial infections like Vibrio, even webbing. Many of these infections are highly contagious to other syngnathids (including your pipefish) and incurable, even with prophylactic treatment. Even expert seahorse keepers who are capable of raising fry have had bad luck with these "tank raised" seahorses.

Now, some other problems with this system--breeding a seahorse using unfiltered natural seawater and mostly natural foods from the ocean is really cheap. The cost is next to zero. That makes net-pen raised seahorses very inexpensive. Legitimate, careful captive breeding for the hobby costs money. Most seahorse breeders charge from $50-$100 per seahorse, and they never take home a paycheck.

The most commonly "tank bred" or net pen raised seahorses are H. kelloggi and H. kuda. These species are not always native to the areas where they are being net pen raised. This means that some hybrids have been reported. Hybrids making it into the trade, and hybrids in the wild. Also, it's difficult to quantify exactly how much waste and pollution is produced by this method of breeding tons and tons of seahorses. But I can assure you, it is not minimal.

Many Tank-raised or net-pen raised seahorses that make it into the trade are sold by local fish stores and online retailers that often don't have a dedicated syngnathid system. Many consider brine shrimp an acceptable food source (See Scott Michael's "Reef Fishes"). They most often keep them at tropical temperatures above 74*F, which are proven to increase Vibrio infections (see "Working notes: a guide to seahorse diseases" by Belli M.D., Driscoll, Lamont). Also, they are kept in systems that contain many different species of seahorses and other syngnathids, also increasing chances of disease. Many people believe that this is the main reason that TR seahorses are not as hardy as their CB counterparts.

Back to the money issue. In the past year, most of the legitimate captive breeding facilities have closed down. Draco Marine just stopped production. There are only a couple left, NYseahorse and Dan U. from seahorsesource in Florida. Neither have much in stock right now. There is still Ocean Rider in HI, but that's only if you want to pay $150 up to $999 for a single seahorse.

As far as I know, no one is Captive breeding kelloggis in sterilized natural sea water. Unfortunately, not much is known about kelloggi seahorses, except how to mass produce them. Being a deep-water seahorse, it is speculated that they may prefer temperatures even lower than where most people keep their seahorses at 74*. They have a horrible track record in captivity.

So next time you go into your LFS and you see a H. kelloggi or worse, Hippocampus sp. or "yellow seahorse," please pass on it. You'll be saving yourself some heartache. Educate your LFS and even your favorite online vendors. Tell them that you demand legitimate Captive Bred seahorses. Help your LFS create an environment that is safe for SH. Educate other beginning seahorse hobbyists. Be cautious and do your homework.

Be careful, some otherwise reputable and respectable vendors and retailers are being sneaky. Even ORA is importing reidi (native to the New World) seahorses from Asia that they claim are "Pond Raised." Communications with ORA has left it unclear exactly what "pond-raising" is. Bottom line is, I want to know where my seahorses came from. How they were raised and kept is too important.

I have made a promise to myself, and to the seahorse hobby, to never buy a tank bred seahorse. I will only buy from a legitimate captive breeding facility that uses either synthetic or filtered, sterilized seawater, bare bottom tanks, and frozen mysis. Join me, and make the promise. There is no other way to save this wonderful seahorse hobby. IF WE DON'T STOP BUYING TANK RAISED SEAHORSES, SOON WE WON'T HAVE A CHOICE!

Not true. Many breeders mix their seahorse stock, and Mic Payne in Australia mixes his CB pipes with his CB seahorses too. Thats why the issue is with mixing sources, not mixing species, when it comes to CB. Its a good idea for breeders to mix their own stock, it exposes them to small amounts of various bacteria, making their stock more hardy in the home aquarium, and making it possible for customers to mix species as long as they buy from the same source. It is important to remember, though, that not ALL breeders do this.

CITES has limited the distribution of WC seahorses, so you probably won't see them around much.
Specifically, countries who choose to participate in CITES, follow the minimum guideline that they do not export seahorses smaller than a set size and that the seahorse export does not negatively impact wild populations. It is important to remember that some countries choose not to opt into CITES, and some countries choose to have more strict guidelines than CITES. It is also important to remember that CITES only deals with export, and does not deal with WC seahorses that are native to your own country (for example: zosterae and erectus in the U.S.). You do see plenty of WC erectus and WC zosterae in the U.S., in fact the large majority of zosterae purchased in the U.S. are WC.

I don't know how to do the quote thing on this forum. I appreciate your help, Ann. Frankly, I'm a little sad that I'm not getting any input from the people I thought I would be getting input from...Actually, a lot of what I HAVE been getting is downright opposition or being accused of ulterior motives, like being affiliated with certain CB suppliers. Ok, I'm done whining now.

I almost wanted to give up on this and leave it to gossip to get the word around. I am not a good writer anyway, so I wish someone would just rewrite/edit the article for me!

You're right about captive breeding facilities mixing species. I wasn't sure how to put that in the article, because I want to separate the fact that LFS and holding facilities do it, and that CB facilities do it. And I don't want to keep doubling this article's size...

I also thought about mentioning WC dwarf SH, but didn't think it was relevant. And I've never seen a WC erectus for sale, but I'm sure they are out there. Maybe I'm just not looking. Thanks for that info, I should include it, but like I said, I'm trying to keep the article relatively short--maybe I should just throw that idea out the window.

There were a few CB facilities that are no longer in production, or more accurately, many that are hurting for business. Marine Depot told me that all their SH are WC and that they considered buying from dracomarine, but that it was more expensive.

Umm, that seahorseusa shut down a couple years ago, but honestly, I doubt it was a direct result of competition from TR SH. Seanic aquariums has also been gone for a long time.

If you want input from certain people, PM them. I'm not sure who you are looking for input from, but if its the breeders, IMO they try to be polite businessmen and women on forums and they aren't likely to jump in with their .02 on issues like this in the forums. It would be unprofessional. If there are things you want clarified, or questions you want answered though, just ask (me, them, everyone). I only say this because I am having trouble figuring out what input you want either, and I'm active in your threads, so the people who's input you want, may not even know they have the answers you are looking for.

I'm not a breeder nor affiliated with any breeder in any way ..,

Pen-raised horses, which are far cheaper to raise, drive the prices down on professionally raised CB horses. This would be fine if the two products were equal ... but they're not even close to equal. Its like selling junk jewlery along side real diamonds and to this point many seahorse buyers don't seem to know the difference.

I agree, this is a threat to the hobby. How can professional breeders stay in business selling their diamonds at prices heavly influenced by the junk jewlery market? Draco is a prime example. and the few others could follow. imo.

Just to clarify, MollyM knows that I am not challenging the premise of her article, but it seems like everyone else reading this thread thinks that I am. (At least the PMs mean that people are reading your thread Molly).

I am NOT against captive bred seahorses, I am NOT for the collection of WC seahorses for the general hobbyist market, I am NOT under the impression that tank raised do not pose a thread to captive breeders.

However, I feel like if one side is going to be passing around misinformation, the biggest disservice we can do to our own side is to also pass around misinformation, because if a few points are wrong, people have a tendency to dismiss all points as being wrong. With that in mind, I am challenging the incorrect bits, the bits that generalize or only focus on the U.S., and the bits that are mostly opinion rather than fact; with the idea that they are weakening the effectiveness of the article.

My LFS uses the term Tank Raised for Aquacultered sea horses that they get from their supplier. Would these be okay to buy? Most of them are H. Erectus.
He also uses the term NET for Pen-Raised seahorses.
What would be your opinion on this? I am going to be in the market to buy seahorses and want to do the best I can to help myself and the hobby.

CCall, I would make sure you know who the supplier is. If it is an aquaculture facility like ORA, then you are solid, although I would pick them up in the bag and not have them aclimated to your LFS tanks. But, if they are from "a wholesaler" or "a supplier", I wouldn't risk it. Your LFS doesn't know where the seahorses from the wholesalers come from, and they can only go by the labels that the wholesaler uses; which is how all of these net pen raised seahorses get the label "TR" in the first place.

Bill Stockley stopped breeding and selling CB seahorses as well. I am not sure why, but there were rumors it was from pressure by OR, not net pen rearing.

As for mixing species, I think some of the problem is not exposing some CB seahorses to various common pathogens. I know there was work some time ago using vibrio vaccines on seahorses, and they showed a much higher resistance to disease. But obtaining them for small operations and individuals was very difficult.

Then there is a problem with correlation not equaling causation. Some seahorses get sick in a mixed species aquarium, and the assumption becomes it was related to mixing species. This may or may not be true, but it doesn't explain the mix species aquarium that work. Its probably wise to keep species separate though until a more clear answer is found.

Those points aside, this is a great summary. I absolutely agree Net Pen Raised seahorses are not good for the aquarium. It might help with conservation, but it doesn't do anything to eliminate the problems we had with wild caught seahorse survivability. If wild caught seahorses are dying because they are being poorly handled and shipped half way around the world, then these seahorses aren't going to fair much better.

I want everyone to keep in mind, this article is still a rough draft. I'm certainly not qualified to write it. I just wanted to get the ball rolling, sort of manifest what's been on everyone's minds in the SH community right now. I still need some help with the actual copy and with obtaining references and photos. And I DO appreciate corrections because, like I mentioned, I don't have many references...and if we want to get this important issue out into the open, we better know what we're talking about!

Ann, I always appreciate your input! I like that you are always to-the-point, and not condescending like some people can be. Ann and I are on the same side here, in fact, all SH hobbyists are on the same side when it comes to this issue, whether they know it or not.

CCall, does your LFS keep the CB and the Net raised SH in the same system? If so, the CB are potentially exposed to the same pathogens as the net pen raised. That could cause a problem.

I think it's very helpful when breeders breed SH and pipes and different kinds of SH together. I don't know how they do this, but I presume they are using quarantining, bare bottom tanks, adequate water params, possibly UV, slow, professional methods that work without crashing all their stock...

But when the LFS or LA wholesalers are "mixing" there is a different outcome. They are mixing animals that were just shipped, possibly halfway across the world. These animals have lowered immune systems already. Then they are often kept in less than optimal water parameters and conditions, at temperatures that are too high. We've all seen the LFS SH tanks with aggressive fish or stinging corals in them, also. These systems often also house live rock and sand (places for pathogens/ciliates to collect. As David W. says "clean your pipes") and other creatures. That's when we run into a problem with mixing.

Hydroid, I like your metaphor.

Fishgrrl, BINGO. I'll post it over there when I feel comfortable with its accuracy. It may take some time. I'd appreciate any help (any of) you can give with references, photos, corrections, additions...
