Optimization of Dietary Protein Requirement for the Growth, Survival and Feed Utilization of Osteobrama belangeri (Valenciennes, 1844) Fingerling

Effect of Graded Protein Levels on the Growth, Survival and Body Composition of Juvenile Osteobrama belangeri using Semi Purified Diet

“…The dietary protein is considered as vital in the nutrition and feeding of fish and thereby adequate supply of dietary protein is essential for better growth and survival (Shang et al, 2018;Ramesh et al, 2017;Lovell, 1989). Many workers have studied the dietary protein requirement of different aquaculture fish species (Surjobala et al, 2019;Ramesh et al, 2017;Paul and Giri, 2015;Siddiqui and Khan, 2009;Santiago and Reyes 1991) and they have found that the dietary protein requirement for fishes differs from species to species. This is mainly because of their feeding habit, size of fish and water temperature of the particular environment.…”

“…Optimum protein requirement was found to be 30% for bighead carp (Aristichthys nobilis) (Santiago and Reyes 1991), 25% for O. belangeri fingerling (Surjobala et al, 2019), 45.1% for fry of O. belangeri (Ramesh et al, 2017), 41.4% for pre-adult gilbel carp (2017). Martinez-Palacios et al (2007) and Lee and Kim (2009) explained that specific growth rate is an excellent indicator of protein quality and decreases as fish increase in size.…”

“…Li et al (2000) observed a significant growth response in channel catfish (Ictalurus punctatus) when the experiment was conducted using different protein rich artificial diet and is in agreement with the present findings. Ramaswamy et al (2013), Ye et al (2017), Surjobala et al (2019) reported that the decrease in growth rate of fish when the protein levels reach the optimum requirement, which might be because of the fact that the fish body cannot utilize the dietary protein after reaching the optimum protein level as required by the fish.…”

“…Effect of Graded Protein Levels on the Growth, Survival and Body Composition of Juvenile Osteobrama belangeri using... optimization of protein requirement study of fingerling (Surjobala et al, 2019), protein requirement study of fry (Ramesh et al, 2017). But, protein requirement of juvenile O. belangeri were never estimated.…”

Effects of Varying Dietary Protein Levels on Growth Performance, Survival, Body Composition, Haemato-Biochemical Profile, and Metabolic Responses of Hypselobarbus jerdoni (Day, 1870) Juveniles

“…Terefore, dietary protein optimisation of a species at various life stages is critical towards making aquaculture lucrative and sustainable. Accordingly, various authors documented the optimum protein requirement of various barb species, such as 500 g protein/kg for tinfoil barb fry [22], 300-350 g protein/kg for lemon fn barb hybrid fngerlings [22], 350 g protein/kg for Puntius vittatus [23], 300 g protein/kg for Puntius gonionotus [24], 297 g protein/kg for Labeo bata fry [25], 281.48-282.53 g protein/kg for Cirrhinus reba fry [26], 250 g protein/kg for Osteobrama belangeri fngerlings [27], 290 g protein/kg goldfsh fry [28], and 318.0-327.6 g protein/kg for Hypselobarbus pulchellus fngerlings [29]. In this regard, the present research explores the dietary protein requirement of Jerdon's carp (H. jerdoni) since it is a relatively new commercial ornamental fsh, and many aspects of its culture including its food and feeding habit as well as nutritional requirements have not been examined yet.…”
