Nghiên cứu thuần dưỡng cá tỳ bà bướm beo (<i>Sewellia elongate</i>) để bảo tồn chuyển vị tại thành phố Hồ Chí Minh

Abstract

    Sewellia elongate was a freshwater ornamental fish that was exploited from the wild to serve the needs of domestic and export ornamental fish. The survival rate of the artificial culture was low because the fish was exploited mainly from the natural environment without going through the domestication process. The study was carried out to domesticate Sewellia elongate which was collected in the central provinces and suitabled to artificial culture in Ho Chi Minh City. The study consisted of 3 experiments: (1) Research on changing habitats; (2) Research on changing water temperatures; (3) Research on the effect of different foods. The experiment was arranged in a completely randomized design with 3 treatments and each treatment was repeated three times, cultured in a glass tank with size 1.2 x 0.5 x 0.5m. The experimental period was 60 days. The results illustrated that the fish was completely adapted to the artificial environment such as the water temperature from 22 to 24^oC; eated pellets; aquarium plants or arranged driftwood in the tanks. The survival rate of fish was recorded from 75 to 87%. Fish had beautiful colors, clear patterns similar to natural fish.
