<< Spawning these fishes in aquaria without hormone injections is not
practical.
They are large fishes (gizzard shad reach 20 in, threadfin 9 in), and will
only
spawn in large schools. >>
Thanks, Chris! I guess that aquarium spawning of gizzard shad was more
difficult than I thought! Btw, do you know where to get the hormonal
injection supplies?
Just playing :)
Guess I gotta scratch them off of my list of Michigan fishes to spawn. :(
<< These same
researchers believe that spawning in the early morning avoids the prime
feeding
time of predators such as largemouth bass and sauger. >>
That's odd, I thought that saugers at least were early morning and evening
feeders. But perhaps it is walleye and yellow perch that I'm thinking of.
