“…When re-feeding is done, energy comes from feed protein for growth (Khotimah, 2009). Prakoso and Kurniawan (2017) reported that best tilapia fasted for 7-14 days experienced a decrease in body weight, however, after refeeding 42 days at the end of the experiment, it showed that the fish biomass that was fed restricted for 7 days showed a higher value than control.…”

Highlight ResearchThere has been a significant decrease in growth, condition factors, hepatosomatic index along viscerosomatic index with the length of time for feed restriction, although fasting for up to 28 days did not cause fish mortalityHematological parameters such as RBCs, WBCs, hematocrit, and hemoglobin decreased significantly, but after re-feeding increased significantly in consecutive timesThe blood glucose levels decreased during feed restriction and gradually increased after re-feedingFeed restriction ﬁsh gained weight continuously during re-feeding, but no displaying compensatory growthThe decrease in hematological parameters did not indicate stress levels in fish, but reflected a lack of nutrition condition AbstractThe management of red tilapia culture can be improved through restriction of feed. This study aimed to determine the impact of feed restriction time and re-feeding on the growth and hematological performance of juvenile red tilapia. This study used an experimental method with a completely randomized design consisting of five treatments with four replications, namely the fish were given food for 28 days (A), 7 days of feed restriction followed by 21 days of refeeding (B), 14 days of feed restriction followed by 14 days of refeeding (C), 21 days of feed restriction followed by 7 days of refeeding (D) and 28 days of feed restriction (E). The parameters observed were growth, biometry, and hematological values. The results showed that during the feed restriction period there was a significant decrease in growth, condition factors, hepatosomatic index along with viscerosomatic index with the length of time for feed restriction, although fasting for up to 28 days did not cause fish mortality. Hematological parameters such as RBCs, WBCs, hematocrit, and hemoglobin decreased significantly, but after re-feeding, they increased significantly in consecutive times. As for the blood glucose levels decreased during feed restriction and gradually increased after re-feeding. This study stated that feed restriction ﬁsh gained weight continuously during re-feeding, but no displaying compensatory growth. The results suggested that the decrease in hematological parameters did not indicate stress levels in fish, but reflected a lack of nutrition condition.

“…In addition, due to the use of different types of chemicals includes heavy metals and antibiotics in fish feed deflating the nutritious quality, effects on fish growth and diseases resistance capacities, thus raised potential risk on human health by consumption [10,23]. In aquaculture, feeding cost is responsible for over 70 percent of the production cost thus inefficient feed management increase the fish production cost [20,24,25]. Balanced feed is essential for better fish growth, reproduction, and other physiological functions [4,25,26].…”

Aims: Nile tilapia is one of the most consumable and economical fish species in Bangladesh, traditionally co-cultured by sharing with prawn, shrimp and Indian major carp. In tilapia monoculture, suitable protein level in the diet is crucial for better growth of the fish as well as being economically viable. Addressing this aspect, here in this experiment we tried to adopt suitable and economically sustainable feed for better tilapia growth and production. Place and Duration of Study: The experiment was carried out for 75 days in the wet laboratory of FMRT discipline of Khulna University. Methodology: Three available commercial feed with protein percentages of 32.5% (T1), 35% (T2) and 28% (T3) were fed to the juvenile tilapia (mean weight 0.31g) under the laboratory condition. Fish were nursed in rectangular glass aquaria tank (volume 25L) with each three replications for 75 days at the stocking density of 25fry/tank to determine the effect of these feed on growth of tilapia fry. Results: After 75 days culture period the final weight of tilapia under treatment T1 (4.68±0.28) were significantly (p<0.05) higher than treatment T2 (4.01±0.19) and T3 (3.26±0.39). Similarly, the highest SGR was found in T1 followed by T2 and T3, however no significant difference observed among the treatments. FCR was significantly different among the treatment, where the lowest FCR was found in T1 and higher at T3. In contrary, PER was opposite to FCR values, higher in T1 and lower in T3. Again, significant different were observed in protein, lipid and ash content of tilapia among the three treatments. Water quality parameters were found at suitable farming ranges throughout the experimental period. Conclusion: The finding of this experiment suggested that 32.5% protein enriched feed can be suitable for the better growth of tilapia.
