EBJD Dead

[knicks791]

I have a ebjd myself and pretty sure its inbreed. I wouldn't be suprized if it died, just like many of the other MFK members who have had EBJD.

There are breeders out there that post pictures of the parents to show they are not inbreed.

But to answer your question, I have not had any die.

OK I was just checking but with all that said even with pics your still not sure if they are not inbreed.

Many many species of fish are inbred. They aren't really affected for a few generations.

When breeding EBJD most breeders use an EBJD male and a female BGJD. Breeding EBJD and EBJD results in very weak fry that usually do not survive, if they even hatch. The resulting spawn from a EBLD and BGJD results in 50% EBJD fry. They are still sensitive to parasite infections and dying before hitting 3". This is just a sensitive color morph.

EBJD are such a rip off. Those things just up and die if you look at them wrong.

I agree.

Man those are really nice. Now when you say push water thru UV to fast what do you mean by that?? Are there different speeds on it???

The more complex the organism the more UV exposure it can tolerate...

For the full benefits of UV including killing parasites I strongly recommend:

1W of UV strength per 10 gal of tank volume...
10 gph of flow per 1W of UV strength...

Thus a 9W UV with 90 gph flowing through it on a 90 gal tank would be ideal...

Using a slightly larger UV will have no ill effects except it will cost mroe to set up and replace the bulbs for...

Flowing slightly slower than 10 gph is fine, although I would still want to keep the "one turnover" guideline in effect...


For reference: I run 9W UV's on 75/90 gal tanks... I run a 20W UV on my 125 gal... I run a 20W UV on a system of three tanks tied together totalling 200 gal...

They die cuz they are are inbreeds.

I agree they are excessively inbred... and most of their 'problems' are right in line with common symptoms of inbreeding depression...

I'm convinced inbreeding does have something to do with it, but I also suspect the mutation itself has a lto to do with it.

When I first starting keeping/breeding Blue Dempseys I put the majority of the blame on inbreeding, but the more I learn about genetics/genomics the more I believe that protein development has a lto to do with it (in addition to the inbreeding depression).

Don't think I agree with you. From my understand a lot of fish are inbreed. So how many of your inbreed fish have you had die???

In fish, a little inbreeding isn't a bad thing... but there is a tipping point at which it becomes excessive.

As described above, I am convinced that due to the nature of how the Blue mutation is passed (Mendelian Genetics) breeders have cut corners time after time and have crossed the line of "safe inbreeding" an dhave entered intot he waters of "excessive inbreeding".

Yet again, I do not believe inbreeding depression alone is the cause for them having inferrior health in comparison to standard Dempseys...

EBJD are such a rip off, They sell locally here for $25-30 each. I have had 4 of them and the biggest I ever got one was about 4 or 5''. Those things just up and die if you look at them wrong. My ph is within range and I use uv lights for parasites. I won't waste my money on another EBJD.

Yeah I think EBJD's are just good looking then you don't realize the parasitic hazard they carry with them.
