Growth curves of Nile tilapia (Oreochromis niloticus) strains cultivated at different temperatures
Growth of Red, GIFT and Supreme Nile tilapia strains were evaluated. Fish were cultivated in indoor recirculation systems in 0.5 m3 tanks with controlled temperatures of 22, 28 and 30°C. Random samples of 20 fish from each strain (10 fish tank) were weighed at day 7, 30, 60, 90 and 120. Exponential model (y=Ae) and Gompertz model (y = Aexp(-Be)) were fitted and the estimates parameters were obt...
متن کاملEffect of Different Salinity Levels on Growth and Survival of Nile Tilapia (oreochromis Niloticus)
A three months study was conducted in cemented tanks (2.896ft×0.762ft×0.914ft) to investigate the effect of different salinity levels on growth performance and survival of Nile tilapia (Oreochromis niloticus). Four salinity levels i.e. 1600 ppm in Treatment 1 (TI), 2400 ppm in TII, 3200 ppm in TIII and 4000 ppm in TIV were maintained while in control (T0) the salinity level was 800 ppm. Each tr...
متن کاملApplication of Bacillus amyloliquefaciens as probiotic for Litopenaeus vannamei (Boone, 1931) cultivated in a biofloc system
Probiotics can improve growth, survival and resistance to pathogenic organisms of the cultivated species in aquaculture systems with water recirculation. However, their possible benefits on biofloc systems have been less studied. In this study, the benefits of Bacillus amyloliquefaciens bacterium, on a biofloc culture of Litopenaeus vannamei were evaluated. B. amyloliquefaciens was applied as d...
متن کاملEffect of Stocking Density on Monosex Nile Tilapia Growth during Pond Culture in India
Stocking density is considered one of the important factors affecting fish growth. But, information related to impact of stocking density on growth performance of monosex tilapia population under the ecological conditions of Gangetic plains in West Bengal, India is limited. The aim of our study was to compare the growth potential of monosex tilapia at various stocking densities and to determine...
متن کاملOntogeny in the visual system of Nile tilapia.
Retinal neurogenesis in fish facilitates cellular rearrangement throughout ontogeny, potentially allowing for optimization of the visual system to shifts in habitat and behaviour. To test this possibility, we studied the developmental trajectory of the photopic visual process in the Nile tilapia. We examined ontogenetic changes in lens transmission, photoreceptor sensitivity and post-receptoral...
