However, the
conversion efficiency of feed to seed declines and from a
practical standpoint, it might not be advantageous as
brood fish grow faster and larger fish are difficult to
handle necessitating early replacement of the brood stock
which can be costlier.Nevertheless, it can be recommended
that hatchery operators keep their broodstock at
higher stocking densities under restricted feeding regimes
when there is low demand for seed and boost production
using stunted broodfish with higher feeding rates when
the market demand for seed increases and allow one
month of feeding at 3% body weight before spawning.
