Backyard Aquaponics
A place to discuss aquaponics

Hi everyone,

Been lurking here on and off for a few years now. What a great community with a wealth of technical and practical knowledge!

My name is Dan and I have been and avid aquarist since I was a child and have at various times maintained over 40 aquariums. I have spawned and raised about 60 fish species, including tropical marine fishes. Also dabbled with small ebb and flow and NFT hydroponic systems.

I think it is time to integrate two of my great interests, fish and plants. I have quite a specific question to ask as well as a couple of more general ones so will head over to the General Discussion board.

Welcome Dan, your knowledge will be greatly recieved around here. Next point of discussion, how to spawn yellowbelly, so i don't have to keep buying them

Thanks for the warm welcome Asitis. Unfortunately I have no experience with any native fish besides Rainbowfish . Not one of those pesky migratory spawners are they?

Through reading I believe they need water temp above 20deg C coinsiding with a simulated flooding, increased water height, flow, nutrient levels etc etc. Commercially breeders inject adults with hormones to initiate spawning, mostly female, but even then they need to be with a consensual/formed partnership. Oddly once they are successful they have very high hatching rates 80-100%, otherwise zero in and unsuccessful mating, typically nothing in between. (Silvers and bass where closer to 30% hatching from memory). So definitely suited to the flood/dry cycle of the murray darling eiver basin.

Either or it would be far easier if rose petals , chocolates, fine wine and softly played Barry Manilow were the prerequisites for copulation.
