| Summary: | Clarias gariepinus is a remarkable freshwater air-breathing catfish native to Africa. Its distinctive characteristics, including omnivorous feeding habits and adaptability to challenging environmental conditions such as low dissolved oxygen, fluctuating temperatures, and elevated water pollution levels. The objective of this experiment is to investigate the weight recovery after short-term starvation and re-feeding. One hundred and fifty (150) African Catfish (C.gariepinus) fingerling was obtained from aquatic shop in Bintulu with initial weight and length approximately 0.71 ± 0.02 g and 4.0 ±0.09 cm, respectively. No significant different on the size of fish used for each treatment. Six aquariums (45cm x 30 cm x 34 cm) were used, and each aquarium were organized into 5 equal partitions with total of 30 fish for each treatment. The fish were grouped as a control (normal feeding), 1-Day, 3-Days, 5-Days and, 7-Days starvation period with three repetitions of starvation and re-feeding. Weight and length data subsequently taken after each starvation and re-feeding period throughout the study. The growth performance significantly different between the control group and the starvation treatment. The final weight for the control group (28.03g) significantly higher as compared to 1-Day(15.34g), 3-Day(15.32g), 5-Day(11.57g) and 7-Day(10.07g) treatments after 42 days of starvation and re-feeding regime. Poor growth recovery was experienced by the fish that has been starved from 1 day to 7-day period. Therefore, it is strongly to recommend to not skip daily feeding routine that may disrupt the growth performance of C. gariepinus. The findings of this study convey a crucial message regarding the importance of adhering to the no-skip feeding practice adopted by certain catfish farmers. |
