Nghiên cứu này nhằm xác định màu bể nuôi thích hợp cho tăng trưởng, tỷ lệ sống và hiệu quả sử dụng thức ăn của cá khoang cổ nemo. Cá giống có kích thước ban đầu 3,30 cm và 0,65 g/con được thả vào 6 bể kính có dán màu sắc khác nhau (trắng, trong, cam, xanh, tím, đen). | TNU Journal of Science and Technology 228 13 95 - 103 EFFECTS OF TANK COLOUR ON GROWTH SURVIVAL AND FEED ULTILIZATION EFFICIENCY OF FALSE CLOWNFISH Amphiprion ocellaris Cuvier 1830 Tran Van Dung1 Nguyen Huu Khang1 Tran Thi Le Trang1 Hua Thai Nhan2 Pham Quoc Hung1 1Institute of Aquaculture - Nha Trang University 2College of Aquaculture and Fisheries - Can Tho University ARTICLE INFO ABSTRACT Received 28 4 2023 This study aimed to determine the optimal tank color for the growth survival rate and feed ultilization efficiency of false clownfish. Juveniles Revised 25 7 2023 with an initial size of cm and g fish were placed in six Published 28 7 2023 differently colored glass tanks white clear orange blue violet and black each with a capacity of 60 liters and attached to a circulating KEYWORDS biological filtration system. Fish were cultured at a density of 15 fish tank with each treatment having three replicates for 60 days. Results False clownfish showed that tank color significantly affected growth rate indicators Feed ultilization efficiency length weight coefficient of variation and condition factor and feed Growth rate utilization efficiency feed intake feed conversion ratio feed efficiency ratio and protein efficiency ratio of false clownfish P lt . Fish Survival rate cultured in white and blue tanks had the best results followed by violet Tank color and orange tanks while black and clear tanks had the lowest results. Tank color did not affect the survival rate of the fish P gt . These findings underscore the importance of tank color in false clownfish farming with white and blue tanks being the most suitable for culturing this marine ornamental fish species.
