Effects of initial stocking size on the growth of Nile tilapia fingerlings in cages without supplemental feed in Laguna Lake, Philippines

Abstract

Oreochromis niloticus fingerlings were stocked at three different initial size ranges of 1-3, 7-12 and 20-30 g in fixed net cages in Laguna Lake, Philippines. These were reared without supplemental feed for 120 days. Fingerlings with the biggest initial size at stocking were the most efficient in terms of average weight gain, average final fish weight and total fish production.
