Every time you seine fish you stress them. The OP would have to run ALL the fish through a grader to transfer smaller fish. (seine, remove fish from seine, grade inside a holding tank, return larger fish to the grow-out pond).
esshup (and others),
I was asking about much simpler process than that.
I was wondering if you partially seined after X days with no sorting, and moved over SOME BG presumably containing the bell curve of fish sizes at that age.
And then you later seined again after X plus Y days, and subsequently moved over some more BG that were presumably larger at that age.
Answers I don't know:Does stocking a main pond in a single iteration increase the survival rate of the stocked fish, in the case where you are worried about "immediate" predation? Presumably by the predator fish becoming sated?
Does removing a significant number of fish from a grow-out pond (with a population below the carrying capacity) substantially increase the growth rate of the remaining fish?
