Red Tilapia Broodstocks and Larval Production Under Different Water Salinities Without Acclimation

Assessment of Optimum Salinity Level for Maximum Growth and Survival of Nile Tilapia, Oreochromis niloticus (Linnaeus 1758)

“…They obtained best growth of Nile tilapia when reared at 10‰ salinity level with different feeding frequencies in seawater tanks. In the present study, specific growth rate (SGR) of the fish at 10‰-20‰ was higher than the findings of Sallam et al (2017). According to them, red tilapia showed good growth (SGR 0.56-0.85%) at salinity ranging from 9‰-36‰.…”

“…Similarly, salt acceptance defines a complete fitness or production of fish in a saline atmosphere (Cnaani and Hulata, 2011). Several cichlids have shown curiously acceptance in brackish water or seawater environment for growing and even for breeding in sea water (Kamal and Mair, 2005;El-Syed, 2006;Parry, 2007;Lawson and Anetekhai, 2011;Sallam et al, 2017). Due to shortage of freshwater in the biosphere, it would be helpful to raise tilapia stocks in brackish or seawater environments to certify a source of low-priced and high-quality protein (animal origin) for future (Mateen and Iftikhar, 2017;Hassan et al, 2013;Sallam et al, 2017).…”

“…A few tilapias are found primarily in saline or pure sea water, particularly Sarotherodon melanotheron (Jeanette et al, 2007;Cnaani and Hulata, 2011). They have gained prolonged popularity, and confidently tilapia hybrids/cross-breed can grow in saline and pure sea water (Kamal and Mair, 2005;Sakamoto and McComick, 2006;Mancera and McCoemick, 2007;Lim and Webster, 2008;Kang'ombe and Brown, 2008;Cnaani and Hulata, 2011;Lawson and Anetekhai, 2011;Fitzsimmons, 2016;Sallam et al, 2017). They are hardy, productive and fast growing warm-water fishes.…”

“…They have short food chain and are recognized as adaptable and herbivorous which mostly eat plankton (zooplankton and phytoplankton), algae, aquatic macrophytes and other plant substances (Cnaani and Hulata, 2011;Ng and Romano, 2013;Saikia and Das, 2015). Therefore, tilapias support to reduce pressure on capture fisheries by rearing intensively (Yue et al, 2016;Sallam et al, 2017). Production response of several breeds and strains of tilapia have been significantly improved through breeding (Dey, 2000;Ponzoni et al, 2011;Fitzsimmons, 2016;Nguyen, 2016).…”

“…It has been successfully reared under an extensive variety of natural conditions, especially in saline areas of tropical and sub-tropical countries (Stickney, 1986;El-Sayed, 2002;Lawson and Anetekhai, 2011;Githukia et al, 2014;Ogello et al, 2014;Siddik et al, 2014). But the data is scarce on its growth and survival with regard to the optimal salt tolerance for sustainable aquaculture in underground saline water or in coastal areas (Parry, 2007;Mateen and Iftikhar, 2007;Abdel-Tawwab, 2011;Hassan et al, 2013;Sallam et al, 2017). The present research reports optimal salinity level for best growth, feed intake efficiency, tolerance and maximum survival rate of Nile tilapia in controlled conditions.…”
