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 کاملStrategies for Nile Tilapia (oreochromis Niloticus) Pond Culture
Different strategies for Nile tilapia (Oreochromis niloticus) culture in ponds with a series of progressive inputs were compared. The sequential experimental stages to increase fish production through intensification were: 1) triple superphosphate (TSP) only; 2) chicken manure only; 3) chicken manure supplemented with urea or urea and TSP; 4) urea and TSP; 5) continually supplemental feeding; 6...
متن کاملBehaviours Associated with Acoustic Communication in Nile Tilapia (Oreochromis niloticus)
BACKGROUND Sound production is widespread among fishes and accompanies many social interactions. The literature reports twenty-nine cichlid species known to produce sounds during aggressive and courtship displays, but the precise range in behavioural contexts is unclear. This study aims to describe the various Oreochromis niloticus behaviours that are associated with sound production in order t...
متن کاملHuman Streptococcus agalactiae Isolate in Nile Tilapia (Oreochromis niloticus)
Streptococcus agalactiae, the Lancefield group B streptococcus (GBS) long recognized as a mammalian pathogen, is an emerging concern with regard to fish. We show that a GBS serotype Ia multilocus sequence type ST-7 isolate from a clinical case of human neonatal meningitis caused disease and death in Nile tilapia (Oreochromis niloticus).
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...
