Through two lab trials, the authors examined the potential of feed additives to increase growth and feed utilization in Nile tilapia.
A recent study compared the growth and survival at different salinity levels of “super male” (YY) tilapia with normal sex O. niloticus reversed to 100 percent phenotypic males.
Early postmetamorphic stages of fish feed mainly on zooplankton. As larvae develop, their dietary requirements change and they adopt adult dietary habits.
Experiment evaluates effects of feed color on the growth and survival of Nile tilapia fingerlings reared in a recirculating system.
Sterilization by induced triploidy is an effective method to suppress natural reproduction and therefore its stunting effect in Nile tilapia grow-out ponds.
Environmental factors can influence the sex ratios of fishes, and this knowledge could be useful to develop all-male Nile tilapia stocks without hormones.
