Abstract

This study is aim to determine feed affect of blood worm on growth and survival rate of Clarias sp. larvae. The experiment was conducted in Juni 2019-September 2019 at Satya Wiyata Mandala University Nabire. Completely randomized design is used in this study which is 3 different treatments and 4 replications; A (Daphnia sp. on first 3 days keeping then been continued with blood worm) and B (blood worm). Obeservational parameter in this study are growth and survival rate of larvae by measuring weight and body length total. The growth were increased in both A and B treatment show the best growth result with an average value of the increases body weight is 23,56% and the increases body length is 1,8 cm. The A treatment show the best survival rate result with an average is 83,20%. Water quality during experiment were measured; temperature 24-27oC, pH 8,4-8,7, DO 9,7-15,2 mg/L, NH3 0,00-0,20 mg/L, and NO2
