Abstract

The objective of this research was to know the effect of salinity on the growth and utilized of feed energy by red tilapia, Oreochromis sp.  Four fishes with 4,15-4,42 g initial body weights were cultured in a 50x40x35 cm aquarium for 40 days.  Fish were fed on these diets three times a day at satiation. Dietary growth rate, feed efficiency, protein and lipid retention increased with increasing salinity (p<0.05).  No significant differences in feed consumption and survival rate were observed at different salinities. From this research it can be concluded that the best condition for red tilapia was salinity of 10-20o/oo.

Key words:  Salinity, growth, feed efficiency, and red tilapia.

 

ABSTRAK

Penelitian ini bertujuan untuk mengetahui pertumbuhan dan efisiensi pakan ikan nila merah yang dipelihara pada berbagai media bersalinitas.  Benih nila merah yang digunakan berbobot awal 4,15-4,42 g/ekor, dipelihara pada akuarium berukuran 60x45x35 cm dengan kepadatan 4 ekor/akuarium, selama 40 hari. Hasil penelitian menunjukkan ada perbedaan nyata terhadap laju pertumbuhan harian, efisiensi pakan, retensi protein dan retensi lemak dengan meningkatnya salinitas (p<0.05).  Sedangkan konsumsi pakan dan kelangsungan hidup memberikan pengaruh yang sama.  Media bersalinitas 10-20o/oo  memberikan pertumbuhan dan efisiensi pakan terbaik bagi nila merah.

Kata-kata kunci:  Salinitas, pertumbuhan, efisiensi pakan, dan ikan nila merah.
