Acceptability of five species of freshwater algae to tilapia (Oreochromis niloticus) fry
(International Development Research Centre, 1985)
Unialgal cultures of Oscillatoria quadripunctulata, Chroococcus dispersus, Navicula notha, Euglena elongata, and Chlorella ellipsoidea were fed to tilapia fry for 30 days. Mean weights and survival rates of the fry were ...
The effects of artificial diets on fry production and growth of Oreochromis niloticus breeders
(Elsevier, 1985)
Tilapia breeders were fed with pelleted supplemental diets containing 20 or 40% crude protein at a daily feeding rate of 1% of fish biomass for 24 weeks in cages and tanks. Breeders were weighed and fry were collected at ...
