Red Tilapia Production in LVHD Cages with a Soy-Based Feed: Hainan, China
Region: Northeast AsiaDownload
A feeding demonstration was conducted in a reservoir near Haikou, Hainan Province, to demonstrate fingerling to market growth performance of red tilapia using the ASALVHD cage production model and ASA soymeal-based feed. Tilapia stocked in three, 1-m3 cages at a density of 400 fish per m3 grew from 78 g to 650 g in 101 days on a 32% crude protein, soybean meal-based, all-plant protein diet. Average FCR for the 101-day feeding period was 1.33:1. Gross production of tilapia averaged 256 kg/m3 in the three trial cages, with 99% fish survival. Tilapia harvested from the three trial cages had good size uniformity and body conformation.
