Title: Growth performance and proximate composition of nile tilapia (Oreochromis niloticus L.) in saline environments
Abstract: A study was carried out to assess the growth performance and proximate composition of monosex Nile tilapia (Oreochromis niloticus L.) in saline environments. The experiment was conducted in earthen brackish water ponds for a period of 10 months. The salt-tolerant roughages including Kallar grass, Para grass and Kochia were used in T1 as supplemental feed while in T2, formulated feed (CP 20%) was used along with salt-tolerant roughages. Fertilization of all ponds was done with goat droppings and nitrophos @ 6000 and 7.5 kg ha-1, respectively. Results indicated that tilapia was found well adapted to the saline environment. However, significant differences (p≤0.05) were observed in growth parameters under two feeding regimes. In T1, the net tilapia production was calculated as 1668 and 911 kg ha-1 year-1 in male and female tilapia, while; in T2, 1890 and 1195 kg ha-1 year-1, respectively. Overall, T2 produced about 1.17 times more weight in both male and female tilapia than T1. Similarly in proximate composition, the protein level was slightly high in T2 as compared to T1 but total lipids were lower in T2 as compared to T1. It may be concluded that the use of salt-tolerant roughages alternate with formulated feed (20% protein) is suitable for monosex tilapia culture in brackish water to get economic production.
