Visual communication stimulates reproduction in Nile tilapia, Oreochromis niloticus (L.).
Reproductive fish behavior is affected by male-female interactions that stimulate physiological responses such as hormonal release and gonad development. During male-female interactions, visual and chemical communication can modulate fish reproduction. The aim of the present study was to test the effect of visual and chemical male-female interaction on the gonad development and reproductive beh...
متن کاملEffect of salinity on food consumption and growth of juvenile Nile tilapia (Oreochromis niloticus L.)
The effect of salinity (0, lO and 20%o, water temperature 28 ± l oC) on food consumption and growth of juvenile Nile tilapia, Oreochromis niloticus L. (9.94 ± 0.15 g) were investigated by feeding group of 20 fish at 2% body weight day·• Individual food consumption was measured using X-radiography. There were no significant differences in growth or white muscle protein concenrrarions among group...
متن کاملDistribution of intestinal enzyme activities along the intestinal tract of cultured Nile tilapia, Oreochromis niloticus L
Regional distribution of intestinal enzymes in Nile tilapia was investigated using enzyme histochemistry. Samples from adult fish were obtained from the five major intestinal segments. Activities of maltase, leucine aminopeptidase, dipeptidyl aminopeptidase IV, lipase, non-specific esterases, and alkaline phosphatase were examined in each segment. All enzymes were present at specific sites alon...
متن کاملANALYSIS OF SEX DETERMINATION IN NILE TILAPIA (Oreochromis niloticus L.): A MOLECULAR GENETICS APPROACH
M. TARIQ EZAZ INSTITUTE OF AQUACULTURE PHD THESIS ii ABSTRACT Seven families of XX and YY homozygous Oreochromis niloticus were produced by mitotic gynogenesis from XY neofemales and their genetic status was verified by multilocus DNA fingerprinting and progeny testing. Two of these gynogenetic families and their corresponding diploid controls were used with 64 AFLP primer combinations in diffe...
متن کاملInvestigation of Acute Toxicity of Alpha-Cypermethrin on Adult Nile Tilapia (Oreochromis niloticus L.)
Alpha-cypermethrin, which is a synthetic pyrethroid pesticide and potential toxic pollutant, contaminating aquatic ecosystems was investigated in the present study for acute toxicity. Nile tilapia (Oreochromis niloticus) adults were selected for the bioassay experiments. The experiments were repeated three times and the 96-h LC50 value was determined for the adults. The static test method of ac...
