ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh dari hibridisasi ikan nila Pandu F6 dengan nila Nilasa terhadap karakter reproduksinya dan performa benih yang dihasilkan. Penelitian ini dilakukan dengan metode eksperimental menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 kali ulangan. Perlakuan dalam penelitian ini: perlakuan A (Pandu F6 ♀>< Pandu F6 ♂). The observed data covering fecundity, hatching rate, egg size, yolk sack larva length and weight, length and weight of the egg yolk off larvae, survival rate, specific growth rate, feed conversion rate, and water quality. The results showed the best value on the fecundity of 1191.67±239.45 eggs/200 g, Hatching rate 80.93 ± 3.90%, Survival rate of 81.55 ± 7.54%, specific growth rate of 7.26 ± 0.25, conversion fodder 0.54 ± 0.02 obtained at the treatment C, but for the diameter and weight of egg, larval length and weight TL, and the length and weight of the yolk egg off larvae for each treatment do not differ markedly. The results showed that hybridization (treatment C) gives a real influence (P < 0.05) of fecundity,hatching rate, survival rate but not with the egg size, larva weight and length, and the length and weight of larvae off yolk. Water quality on the spawning, hatching eggs and larvae found on the maintenance of a decent range for tilapia fish farming Keywords: hybridization, tilapia fish, character of the reproduction, seed performance
