As a lot of you know I've embarked on a breeding project to spawn the Asian River Catfish (Hemibagrus nemurus). This will be the log of progress, I'll post as much as I can about what I'm doing and how I'm doing it. I know that a lot of people are interested in breeding big fish and I'm sure it'd interest a lot of you on the techniques etc that I will be using, it's a first for me and I'm loving the challenge! So without further ado, here we go! This is the pair, a beautiful big male who originally belonged to Trevor ( [MENTION=4918]trk18[/MENTION] ) and the female who I recently got shipped up from Perth, she's much smaller than the male. Female: Male: The plan is to condition them, get the female nice and fat, then check egg stage and induce the release of eggs with this stuff: The eggs and milt will then be stripped and mixed, I'll post more about that when I do it. After they've been fertilized, they'll go into the egg tumbler, this is my attempt at a prototype: As you can see, it still leaks A LOT but soon it should be ready. The idea is the eggs get churned around the bottom until they hatch at which stage the tiny fry will still be getting churned with their egg sacs. Once the fry start free swimming they will swim up to the top and get waterfalled to a rearing tank. Anyone who's used a tumbler for Africans would know the general idea. FEEDING: Right now, the female is getting cut up fish pieces, White Clouds, pellets, Bloodworms and any other little snacks I can gather up for her. The male, however, is being a fussy little sh!t and won't touch anything. After speaking to a few members it sounds like maybe Prawns, Salmon and worms are worth a shot. HOUSING: These 2 will be divided in a 6ft tank as soon as I can get a strong enough divider for them, hopefully being together will keep them interested! They've got bits of PVC and plenty of wood and rocks to hide in. WATER CHEM: pH is around 7, temp fluctuates around 24-27˚. HORMONE: I've been running trials using Ovaprim on my Ranchu and Bumblebee Cats with mixed results including a death (handling related) and plenty of sperm, looks like further trials and research will need to be done. .................................................. .................................................. ................................ So that's about what I've got so far, as I said this thread will be updated as I go along, thanks to the members who have helped me out in many different ways and continue to do so! Finn
