Increasing salinity tolerance in tilapias: selective breeding using locally available strain
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2011, Vol 4, Issue 4
Abstract
The culture of tilapias is an important industry in most aquaculture producing countries in the world. Due to the many favorable attributes of this species of fish, including tolerance to wide range of environmental conditions and fast growth rates, interest in its culture is increasing at a rapid pace. There have been research initiatives on breeding, genetic improvement and stock manipulation in order to increase the resistance of this fish to high salinity levels, enabling them to thrive in brackishwater and almost seawater conditions. Saline-tolerant tilapias have been co-cultured with shrimp in brackishwater ponds as it was believed that tilapias are able to inhibit the occurrence of luminous vibriosis in ponds. This paper describes the selective breeding program that we developed in order to produce high-saline tolerant tilapias by using locally available strains.
