Utilization of Durian Durio Zibethinus seed flour and Kelakai Stenochlaena palustris leaf flour formulation as feed for Nile Tilapia Oreochromis niloticus

Abstract

Small-scale fish farmers have financial limitations to buy expensive commercial pellets to meet fish feed needs. Therefore, it is necessary to find alternative feeds that are cheap and able to support fish growth. Durian seeds (Durio Zibethinus) and Kelakai leaves (Stenochlaena palustris) are potential plant materials for additional fish feed which are abundant in Central Kalimantan Province. This study aims to determine whether additional feed formulations made from durian seed meal andelakai leaf meal can provide significant growth in tilapia (Oreochromis niloticus) rearing. The study used an experimental approach with a completely randomized design (CRD) with 3 treatments and 3 replications. The feed formulation is a mixture of pellets with 95% durian seed meal and 5% melakai leaf meal. Additional feeding is based on the following treatment: Treatment A, given commercial feed made by the factory brand MS prima Feed 1000 as much as 5% of the total weight of the fish kept, Treatment B: given formulated feed (90% pellets + 10% durian seed flour and kelakai leaf flour) as much as 5% of the total weight per day, Treatment C: given formulated feed (95% pellets + 5% mixture of durian seed flour and kelakai leaf flour) as much as 5% of the total fish weight per day. The results showed that the feeding of pellet formulations with durian seed flour and kelakai leaf flour as much as 10 % of body weight per day resulted in the highest growth in length and weight of fish.  Thus durian seed flour and Kelakai leaf flour can be used as additional feed for Nile tilapia to help increase fish growth and reduce fish feed costs.
