Cage Culture of Red Tilapia in Prawn and Shrimp Ponds

摘要

Results are presented of feeding trials conducted in prawn ponds (freshwater) and shrimp ponds (brackishwater) with red tilapia stocked in floating cages. Seven ponds were stocked at a density of 26 cages per hectare. One-hundred nine-gram tilapia were stocked into each cage. Fish survival after eight weeks averaged 98.5%, excluding a set of six cages from one pond which were preempted from the study because of high mortality. The growth of tilapia fed supplemental diets was significantly higher in brackishwater than in freshwater ponds. It is concluded that these greater growth rates are due to a greater availability of natural food organisms.
