Diallel Hybridization of Oreochromis niloticus (Nile Tilapia) to Oreochromis aureus (Blue Tilapia)
نویسندگان
چکیده
A total of 200 fish samples (100 Oreochromis niloticus (Nile tilapia) and 100 aureus (Blue tilapia)) were used for this research aimed to produce a population tilapia species that is skewed toward the male population. Three mating periods carried out in total. The males removed from hapa after each round egg production allow repercussion. Fries experimental units collected, counted, stocked tank with dimension 3 x 1 4 m2 fed satiation while maintaining basic water quality. sex ratio data subjected student t-test analysis, growth parameters examined by ANOVA on Spss version 25. Results obtained showed true hybridization between Nile Blue produced offspring was through interspecific crossing two related strains tilapia. This pattern repeated itself throughout times when pairing initiated. At end trials, hybrids their reciprocals higher number compared female. Hybrid 93% male, hybrid 2 71% male. Furthermore, better performance recorded pure strain despite lower feed intake. Conclusively, best

Production of genetically male tilapia through interspecific hybridization between Oreochromis niloticus and O. aureus
This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...

متن کاملVisual 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 کاملMetacercarial Infection of Wild Nile Tilapia (Oreochromis niloticus) from Brazil
Fingerlings of Oreochromis niloticus collected in an artificial urban lake from Belo Horizonte, Minas Gerais, Brazil, were evaluated for natural infection with trematodes. Morphological taxonomic identification of four fluke species was performed in O. niloticus examined, and the total prevalence of metacercariae was 60.7% (37/61). Centrocestus formosanus, a heterophyid found in the gills, was ...
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...
