One way to breed your Clown Loach

  • We are currently upgrading MFK. thanks! -neo
Second generation hormone - induced clown loaches are being produced in Florida at the Tropical Aquaculture Lab. The breeders were about six inches long when I saw them producing the first generation. The farms don't seem to have gone into production despite available help from the U of FL. In my opinion this is due to the fact that fish is still cheap and available from the wild caught fishery in Indonesia. That fishery is long well established and fine tuned. I doubt, but don't know for sure, that the Indonesians are breeding any commercially. They may be doing so in Singapore. I sent an e mail to an Indonesian fish breeder about the status of the clown loach trade and will post his reply.

The fish also just may be too slow growing as well to produce economically at this time. There seems to be some grow-out of imports once in awhile but I don't think it's of any significant amount.
Florida is prone to unexpected and significant temperature drops and in the past weeks friends with clowns in outdoor ponds had losses. Indoor production of slow-growing long lived fishes is expensive.


The technology has been available to the Florida fish farming community for a long time, yet none of the farmers have taken to producing clown loaches it would appear. I assume for the reasons I stated above - I haven't asked. The technology was available elsewhere much longer. Thailand,Indonesia, China - (PRC and Taiwan), Canada, USA, Europe have all been producing hormonally induced fishes for longer than many people realize. Recently it has been embraced in the former Soviet Union which has been noted in other posts in this thread.

Unfortunately distribution of these drugs is strictly controlled in the USA and you need to know what you're doing even if you can qualify to get them. HCG is easier, but not easy to get and is also problematic - unreliable and one needs to be prepared to lose their broodstock.

I think carp pituitary can be freely traded here but is not dependable and can be damaging to non-cyprinids.

I have seen clown loaches, over the years, successfully bred in the US in indoor and outdoor vats, community aquariums etc. All cases were serendipitous. No, I don't have photos. I don't claim any credit for myself.
 
Sorry, I left something out of my first post that might be helpful to others...the first successful community tank breeding I saw was in 110-125 gallon (???) , high style aquarium with discus and cardinals.The clown loach breeders were no more than seven inches in total length at the time. The tank was heavily planted with Anubias with a thick matt of roots growing in and around pretty densely placed driftwood over gravel. Temperature was mid eighties, fairly soft, pH 6 -6.5. The owner of the aquarium, fed numerous times a day on live and homemade foods and made frequent partial water changes.

The tank was well lit with both artificial and natural light which would be considered, by me anyway, to breeding the species present.
 
I fouled up again! Sorry...I would have considered the bright light an IMPEDIMENT to breeding the clown loaches. At least in this instance I was obviously wrong as the baby loaches swam about just above the substrate.

I apologize for poorly editing prior posts.
 
My Indonesian friend responded to my e mail.
He says there is no commercial breeding of clown loaches in Indo or anyplace in SE Asia that he is aware of.
That business is still dependent on wild capture in the Kapuas river system.
He says the area is being destroyed by deforestation and pollution and expects the poor fishermen to be blamed and the fishery ultimately shut down for the wrong reason.
FWIW
 
That is top notch information, thanks for that!
 
fote3 and ewurm, thank you for acknowledging my posts.
I'm retired from fish breeding. I'm also tired of it.
It's up to you guys. Carry on, guys or gals as it may be.
Every creature on this plantet is charged with - fleeing it's enemies, nourishing itself and reproducing itself. If that doesn't happen, YOU put an impediment in their way.
Good nite,

Actually I have breed Clown Loaches a few years ago but mostly for the fun/challenge as they are so cheap to import. Hormone breeding is such common practice now that its finally starting to filter down to home aquarists at last.

I visit fish farms in SE Asia as often as I can and I can assure you many places do artificially breed clown loaches on a very large scale. One farm distinctly remember produces over a million fish per month. They breed a lot of other fish species too.

Hormone induced breeding is nowhere near as easy as some people like to think. Its just another extention of fish breeding IMO. A big advantage is to prepare a lot of brood stock (like all breeding schemes) as individual fish respond to hormones differently which makes it harder for the home aquarist. Without large economy of scale I estimate it was costing me about 20 times the wholesale price to breed the fish than to buy even though I already do a lot of breeding. Ewurm - your welcome to PM me if you want some private info.
 
Fishdance,

I will contact you offline after the weekend; my family is expected to arrive shortly. To be fair to those following this thread and find value in your comments I will initially respond online.


I have no reason to doubt that you've bred clown loaches nor do I essentially disagree with you about other points you make. I see clown loaches spawning naturally in friend's tanks on occasion. They don't even notice it happening...though they may wonder why their bands have turned gray.

My opinion is someone such as yourself with a purpose to breed them can do so.

One thing I've noticed is sexual maturity seems to be a matter of age, not size necessarily. Most spawnings I've seen have been with six or seven inch fish that were at least three years old. Your comments would be appreciated.

Certainly millions of fishes are bred with hormones...carps, Pangasius, groupers, and many other food fishes. Some ornamentals are byproducts of that industry which you would know of course. I also know that many ornamentals are no longer bred because the market couldn't handle the results of the mass production method. The market can't even handle the mass discus production where the fish are allowed to spawn naturally.

I started with hormones in about 1978 and am retired now. Technically I still own a part of a SE Asian fish farm (Taiwan), but I haven't visited too many others in the last few years. Those I did were marine facilities...where there were more, several hundred thousand more, ornamentals available than buyers.

I never bothered with clown loaches and certain other fishes for the reason you mentioned...too cheap to buy. The only thing that puzzles me about what you relate is that year after year juvenile and extra large clown loaches are sold out early in the season. The medium sizes remain in stock. If it were a captive bred fishery, I think this would not be the case??? I don't really monitor the market much anymore, so I could be totally wrong at this point in time. This is why I contacted my Indonesian friend who is also retired from fish breeding and maybe isn't paying attention to the market anymore either.

I don't know why it took so long to trickle down to the hobbyist except that they read the wrong books, go to the wrong university, or more recently ...participate in the wrong forums.

The hobbyist who does manage to breed something this way, and expects to make money, just finds out someone has done it before a lot better and/or discovers there is no substantial market for the "rarity" they've just mass produced. Arapaima, the other boney tongues or Datnioides are good examples...even though they breed naturally as well, as do most other fishes.


And yes of course, it does take some skill but with the releasing hormones there are much less problems than with the cheaper HCG or pituitarin.

And of course the average hobbyist has a pair or two of something and can't or won't risk losing it, while we may have a hundred pairs available.
If the groupers won't eat after the procedure or we kill them on purpose to take their gametes we all have a nice dinner. If it's a discus we just steam it with soy sauce, ginger and garlic and laugh while we try to convince ourselves it's an aphrodisiac!

Thanks for your correspondence. And excuse me for leaving out Australia in my previous posts, where hormonally induced breeding is also a finely tuned practice...lungfish, both saratogas, and barramundi, grouper (cod in Australia?) , and probably much more.

I probably will do that this summer, as I will have much more free time on my hands. I really appreciate the offer!
