Improved hatchery rearing techniques for the Asian catfish, Clarias macrocephalus (Gunther)

Abstract

The Asian catfish, Clarias macrocephalus, is a popular freshwater foodfish in the Philippines. However, grow-out farming of this species is hampered by the lack of juveniles for stocking. A series of experiments on zooplankton feed density, weaning and stocking density were conducted in order to improve production of C. macrocephalus fry in the hatchery.
