Abstract
Tilapia aquaculture is an important industry in most tropical and subtropical countries in the world. This species of fish is able to tolerate a wide range of of environmental conditions and has fast growth rates, making it a suitable candidate for aquaculture in developing countries. Tilapias are now being cultured in brackishwater ponds, where salinity levels could reach seawater strength during the summer months. Hence, research efforts have been directed towards the production of saline-tolerant strains. Using locally available strains of tilapias, we developed a small-scale hatchery for the production of saline-tolerant tilapia fingerlings. This paper describes the protocol of this small-scale hatchery production system and larval rearing techniques for the saline-tolerant tilapias. It outlines the detailed procedures from broodstock selection and maintenance, hatchery management and larval rearing including production of all-male offpsprings through dietary inclusion of 17-alfa methyl testosterone and acclimation to high salinity levels.
