PENGARUH OKSINGEN TERLARUT (DO) YANG BERBEDA TERHADAP KELANGSUNGAN HIDUP BENIH IKAN GURAMI MERAH (Osphronemus gourami) YANG DIINFEKSI BAKTERI Aeromonas hydrophila

Abstract

This study aims to determine the effect of different dissolved oxygen on survival of red carp fish seed infected bacteria. Infected fish Aeromonas hydrophila by injection with 10⁸ cfu/ml, 1 ml/fish. Since the first day of observed clinical symptoms and survival up to 15 days of the study. The treatment used in this study are A (1-5 ppm dissolved oxygen), B (6-9 ppm dissolved oxygen), C (no treatment or control). The results showed that different dissolved oxygen proved to have no effect on the survival of red carp seed. Treatment B (6-9 ppm dissolved oxygen) is the best treatment to control or minimize the mortality rate of red carp fish seed higher due to Aeromonas hydrophila attack.
