Abstract

New formulation of fish pellets was designed by using earthworm powder and other economical ingredients such as fish meal, soybean waste and rice bran which were calculated using Pearson’s square method. The optimization of steaming process done by One-Factor-at-One –Time (OFAT) method showed that maximum water stability was achieved within 40 minutes steaming time at 80oC steaming temperature. Physical properties tested for soaking, protein leaching and hardness revealed the positive results of stable and durable pellets to be applied as feeding material. Growth performance was tested by applying earthworm-based fish pellets on African catfish and measuring weight and length increment weekly. Weight increment of 6.58% was achieved to suggest the potential of this formulation in catfish cultivation.
