%X The performance of Heterobranchus longifilis reared in earthen ponds fertilized with two organic fertilizers (meadow grasses and chicken droppings) was investigated. The study was carried out in 6 earthen ponds measuring 24.9 square meters each at Nigerian Institute for Oceanography and Marine Research (NIOMR) fish farm Ijoyi-Badore Lagos. Results obtained showed better food conversion ratio value in treatment 1 (1.28 ¡À 0. 11) fertilized with meadow grasses and chicken droppings in combination with commercial extruded feed than in treatment 2 (1.72 ¡À 0.32) fertilized with only chicken droppings in combination with commercial extruded feed. The total weight gain were 665.39 ¡À 22.05Kg and 623.93 ¡À40.64kg respectively for treatment 1 and 2 while the daily growth rate was 4.01 ¡À 0.13g and 3.76 ¡À 0.24g for treatment 1 and 2 respectively. H. longifilis in treatment 1 performed better than treatment 2 probably due to the efficiency of the organic fertilizers in treatment 1 than treatment 2. Fertilizer used in treatment 1 could be used in fish ponds to reduce cost of pond fish production. Keywords: Heterobranchus longifilis; Growth performance; Organic manure; Fertilizer; Feed
