I have an awkward question!

[awdawg]

Not that I have tried it (to my fish duh) or myself personally, but what kind of effects does imbreeding have on fish?

Lets say I have 2 parent flowerhorns, and one of their offspring comse out looking more amazing then either one, but would probably make even better offspring if mated back to the mother or something...

Would that adversly effect offspring? Or would they just not do it? Or does it cause no problems at all?

Any insight would be awesome!

first time around probably no problems....but eventually i think it would get nasty! imo

 

[milkman407]

Would u do your mom? lmao

j/p it would cause problems try breeding 2 pairs and find the ebst offspring from the sperate pairs.

I think you would be ok with just child to parent, but if you did the Child+Parent back to the child you may have some deformites.

Like if you did you mom the kid would most likely come out fine, but if that child....nvm you get the point.

lol I had a feeling this thread would come along with some funny answers, but I figrured I'd like to hear some actual feedback and perhaps from someone that has experienced it (AMONG THEIR FISH) lol. Because I know sometimes the fry come out nicer then the individual parents but the parents or other siblings may contain better traits, and one may not be able to afford another insanely expensive fish... ya know? Well I do have a 3rd flowerhorn if that were to happen! Dont know if its a male or female yet though hehe.... But yeah I would like to hear more if anyone has any insight!

i am in agrement with skilldatzkillz just dont double back.

Here is my last reply on this topic, I hope it helps...

You are speaking of genetic purging

Source http://www.genecomp.com/October_2000.htm

121. Genetic purging may be useless for genetic conservation
Effects of population structures and selection strategies on the purging of inbreeding depression due to deleterious mutations. 2000. Wang, J. Genetical Research 76:75-86.
The author uses simulation and theoretical analysis to come to the following overall conclusion: " it is not justified to apply a breeding programme aimed at purging inbreeding depression by inbreeding and selection to a population of conservation concern". The exception may, perhaps, be species including fish which have a high-enough reproductive rate to overcome the inbreeding depression.
If a decision is nevertheless made to undertake this controversial procedure, "The results show that the effectiveness of purging, the survival of the inbred lines and the inbreeding level attained are generally highest with between-line selection and lowest with within-line selection. Compared with no crossing, line crossing could lower the risk of extinction and the inbreeding coefficient of the purged population substantially with little loss of the effectiveness of purging.

The theory is that after a while of captive inbreeding, the bad genes are purged & the line is pure.

They will breed, the fry will go on, unless they were cross bred with wild blood in the last couple generations, captive line inbred fish will likely be fine.

^^^ ----- or so I hear ---- ^^^​

You can allways see the bad line cast-offs in the goldfish dept. the mutants with eyebags & external brain head

wow... although that seemed rather informative... to me a college graduate yet not a rocket scientist that was damn wordy! anyone wanna make a " Genetical Purging Research for dumbies"? lol I gathered that fish generally arent affected near as badly as other animals and what not.... but wow...

 

[HiGhTiMeZ]

ive read that inbreeding on SOME fish actually works for the better... ive read that it also purge out bad genes...

Ok the short if it is...

Genetic purging through inbreeding will weed out the bad genes if the species has enough offspring to offset the number that will be lost due to purging (death of undesired offsrping)

This will never work in a species that has too few offspring per justation, nor species that require a lengthy justation, due to the loss of population through purging.

The more kids they have, the more likely they are to have offspring that are "pure".
