Tilapia is being cultured both in freshwater and brackish water regions in Asian continent. When this happens, the fry swim through the larger mesh of the inner cage, but are retained within the fine-meshed outer cage. For those who own commercial hatcheries or backyard ponds, harvesting fingerlings are possible. Various authors have reported that breeding ponds stocked with smaller tilapia produce more fry than ponds stocked with larger tilapia. Spring Genetics signed a five-year contract for the supply of broodstock to Acuicola de la Selva S.A.C. Each female group is rested without males at a high density (18 to 20 fish per square meter) in a separate conditioning hapa, and fed high-quality feed after a spawning opportunity of five to seven days. For the stocking density, hapas can accommodate 4 to 5 breeders weighing 50 to 250 grams for every square meter.

Water control structures exist at the inlet and outlet of the pond. The larger cage, constructed of fine, 2- to 3-mm-mesh net, contains a slightly smaller cage constructed of 4- mm-mesh net. In a recent study, tilapia fed 32 percent and 40 percent crude protein levels grew and matured faster than those that were fed less than 25 percent crude protein. The continued deteriora-tion of tilapia stocks through inbreeding could result in the production of poor quality fry and fingerlings. As tilapia grow-out systems intensify, demand for all-male fry or fingerlings increases. in the breeding system helps to reduce social dominance, thereby improving seed productivity and quality. A thorough understanding of these methods is needed to start a productive hatchery. Clutch removal is labor- and timeintensive, and requires facilities and techniques for the artificial incubation of eggs and larval rearing. Feeds loaded in protein, which is either bought commercially or formulated, can be a good source of nutrients. This leads to slow growth and body deformities of the progenies and adversely affects succeeding genera-tions. This file associated with this publication is currently under embargo.
