Duration of feeding and indirect selection for growth of tilapia
(Elsevier, 1986)
Duration of spontaneous feeding was observed at three times each day in a laboratory population of nine juvenile tilapia (Oreochromis mossambicus). Growth of the fish was measured as change in length and weight, and also ...
Cortisol stimulates the size and number of mitochondrion-rich cells in the yolk-sac membrane of embryos and larvae of tilapia (Oreochromis mossambicus) in vitro and in vivo
(John Wiley and Sons, 1995)
The effect of cortisol and thyroid hormones on the activity of mitochondrion-rich (MR) cells in the yolk-sac membrane of tilapia (Oreochromis mossambicus) embryos and larvae was investigated. MR cells were identified by ...
Interaction between test and reference populations when tilapia strains are compared by the “internal control” technique
(Elsevier, 1990)
Several strains of Oreochromis niloticus, O. mossambicus and their hybrids occur in the Philippines, and others are likely to be introduced or developed locally in the near future. Our objective was to study biological ...
The sulfide tolerance of milkfish and tilapia in relation to fish kills in farms and natural waters in the Philippines
(Kluwer Academic Publisher, 1998)
Fish kills of milkfish Chanos chanos and tilapia Oreochromis spp. now occur frequently in brackish, marine, and freshwater farms (ponds, pens, and cages) in the Philippines. Aquafarms with high organic load, limited water ...
Sea lice (Copepoda, Caligidae) parasitic on marine cultured and wild fishes of the Philippines
(The Fisheries Society of Taiwan, 2004)
Four species of sea lice were found parasitic on ten species of marine fishes either cultured in the coastal ponds or occurring in the sea water supply canals in the Philippines. They are: Caligus epidemicus Hewitt, 1971 ...
Evaluation of the salinity tolerance of Oreochromis mossambicus, O. niloticus and their F1 hybrids
(Elsevier, 1990)
The salinity tolerance of freshwater-spawned and reared Oreochromis mossambicus, O. niloticus and their F<sub>1</sub> hybrids of various ages was studied. Several tests were conducted using three indices as practical ...
Effect of different sizes of saline red tilapia hybrid Oreochromis niloticus Linnaeus x O. mossambicus Peters on the growth of luminous bacteria Vibrio harveyi
(College of Agriculture, University of the Philippines Los Baños, 2010)
Luminous bacterial disease caused by Vibrio harveyi has devasted the shrimp industry. The use of different strains of tilapia and other fish species polycultured with shrimp cultured at a salinity of 24 ppt to control ...
