Effect of stocking density on growth performance of monosex tilapia (Oreochromis niloticus) with Indian spinach (Basella alba) in a recirculating aquaponic system

Effect 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...

Effects of the Aqueous Leaf Extract Of Basella Alba on Sex Reversal of Nile Tilapia, Oreochromis Niloticus

Three days old mixed sex juveniles of Nile tilapia (mean weight 0.025 ± 0.009 g; mean length 1.25 ± 0.012 cm) were treated by immersion method with aqueous leaf extract of Basella alba (ALEB) at the concentration of 0.0, 0.05, 0.10 and 0.15 g/l for four weeks. The highest survival percentage (93.8±1.3) was observed in 0.15 g/l group, but there was no significant difference (P>0.05) in survival ...

Bioenergetic modelling of effects of fertilization, stocking density, and spawning on growth of the Nile tilapia, Oreochromis niloticus (L.)

A bioenergetic growth model was developed to examine the integrated effects of fertilization, stocking density, and spawning on the growth of tiiapia, Oreochromis niloticus (L.), in pond aquaculture. The analyses showed that growth rates increase with higher levels of organic ferlilization up to 5(HJkg/ha/week. Growth rates increased with added food rations in ponds, reaching a maximum growth o...

EFFECT OF PROTEIN LEVEL AND STOCKING DENSITY ON GROWTH PERFORMANCE, SURVIVAL RATE, FEED UTILIZATION AND BODY COMPOSITION OF NILE TILAPIA FRY (Oreochromis niloticus L.)

This study was carried out to evaluate the growth response of Nile tilapia; O. niloticus L. to dietary protein levels at two stocking densities. This study was bifactorial designed (3 protein levels × 2 stocking densities). Fish (1.8-2.5 g/fish) was randomly distributed into the aquaria at a rate of 15 or 30 fish/100 L. The temperature was adjusted at 27±1oC. Fish of each density were fed eithe...
