Does in-breeding have any adverse effects on fish ?

Yes. Poor quality and deformities.:)

not all. some fish gets better with in-breeding.

IME this is purty accurate. purifies the genes and such. :D

I can't positively say for fish since I haven't bred any but I show Great Danes in akc conformation so can tell you some about that that I suspect would apply to any animal. You inbreed to strengthen certain desired characteristics but you also increase the chances of undesirable traits at the same time such as deformities. I.e., my present dane, Hudson, has an absolutely to die for gorgeous head but if he had an ancestor along the way with hip dysplasia, or worse yet if HE had hip displasia, and I bred him back to a littermate I increase my chances of getting at least one pup with a gorgeous head but also increase the chances that the pups will inherit hip displasia. It should only be done when you REALLY know your dog's ancestry and after testing for known problems to the breed! (Fortunately Hud's ancestry is clean and he tested clean so he now has 5 adorable new puppies!!!!!!!! http://danemarkdanes.com/litter.html)
Genes are genes so I would think that fish would be no different in this respect.

Excellent Dane Dodger! I agree inbreeding's a double edged sword.

thanks for a great post.

A few things to consider would be why and to what end? I've been straining genes for a couple years now. Why, because I want show stopper fish. Whats been said about the pro's and cons are petty much spot on, although there was one issue missing. Mentaly, multiple inbreds are inferior. New blood every third generation is a plus.

To what end do I do this? I do this with the intent of adding colorfull, easy to keep, fresh water fish to the hobby some day. Oh, and because I can. ;) :D

I got some cousins down south that swear by it!

...sorry, but on a serious note I do have an inbred Cyphotalapia frontosa. It has seven stripes on one side and six on the other. Some fish look cool, but in most cases have lower resale/trade in value. However, there is a pic floating around on MFK of a Flowerhorn that had a heart shaped pattern which fetched a pretty penny. If you can do it then try and see what you get. Just dont trade them or sell them to anyone else.

my guppys breed non stop, i started with 1 male and 2 females that where feeders that i threw in my loach tank. now i am on the 5th gen of guppys with about 20 of the little guys swimming around. kinda gross but it works.

what about convicts? i had a breeding pair that died but the fry survived. Can i breed the pair of fry?

heres another imo from breeding fish and a few other things. inbreeding for traits its acceptable to breed mother to son son to daught but not brother to sister. idea being if there is a recessive trait it is almost 100% siblings are carriers resulting in deformation. but much less likely that one parent and one offspring out of hundreds will carry negative recessive but usually the positive traits are something visual so you cant know for sure. IDK if it makes sense how I explain it but thats the jist of it

I posted a questoin along these lines a while back, I think it was oddball that posted a nice excerpt from a book or something, it said in some cases in fish it can actually weed out impurities in the fish and make them stronger more healthy fish... but who knows lol

[born2lovefish]

how about inbreeding of german rams?
