Body composition, growth performance and enzyme activities of Labeo rohita fed different commercial fish feeds

Abstract

We have evaluated the effects of different fish feeds on the body composition, growth, and enzyme activities of Labeo rohita (Rohu). In total, 240 fishes between the average weights of 24.77±2.15g were studied. The treatments were applied in a completely randomized design, with 4 treatments of 60 fishes each. Treatments consisted of four different fish feeds [Oryza (T1), AMG (T2), Aqua (T3), and Supreme (T4)]. Body composition, growth performance, and enzyme activities were evaluated. There was a significant variation in performance of fishes fed with different type of feed; as fishes having Oryza feed showed the highest weight gain, specific growth rate (SGR), and best feed conversion ratio (FCR) as compared to other groups that were considered to be significant (P ≤ 0.05). High net weight gain was obtained in T4 when compared with T2 and T3. FCR value of T4 was less than T1 but higher than T2, T3 and T2, which showed the lowest values. The specific growth rate was recorded as average in T4, but T2 led a high SGR than T3. Similarly, crude protein level and digestive enzymes activity was recorded significantly highest in fed with Oryza (T1) as compared to AMG (T2), Aqua (T3), and Supreme (T4). Water quality parameters were recorded significant in all treatments except pH and DO of treatment (T1), significantly different from other treatments. It was concluded that Rohu (Labeo rohita) could show a promising growth rate and protease enzyme activity when fed with the Oryza feed of 25% protein.

Effects of different tradititonal and commercial aquafeed on proximate composition and growth performance of Grass carp (Ctenopharyngodon idella) reared in the semi-intensive composite culture system

“…Overall, lesser SGR (1.05±0.001) was recorded in T4. These results match with the findings [30]. In our results, T4 treatment groups showed the higher Crude protein (28.66±0.24%) as compared to other treatments by comparing with [27].…”

“…FCR ratio (2.36±0.01) was also recorded in T3. These outcomes were compared by the findings [29, 30] . Simultaneously, Best ratio of FCR was recorded in T4 (1.86±0.002).…”

“…Physico-chemical parameters like Temperature, pH, alkalinity, phosphate, Nitrate, Dissolved oxygen (DO) and Hardness of water in ponds for different feed treatments did not show any significant variations [27, 30]. The recorded values were within the optimum range.…”

“…Aquaculture has emerged as the fastest growing food production sector as well as it is offering reliable alternatives to high quality production of protein (Abbas et al, 2023;Haider et al, 2018;Iqbal et al, 2020a;Jewel et al, 2020). However, it is constantly facing several emerging hazards that are threatening to the sustainable aquaculture production (Batool et al, 2018;Iqbal et al, 2020b;Mehboob et al, 2017;Ray et al, 2021).…”

“…Fishes are distinct from other species in that they have the capacity to absorb minerals from both their diet and the water through their skin and gills (Abbas et al, 2021). Fish is thought to be the most accurate indicator of water toxicity (Barse et al, 2007;Nasir and Al-Najar, 2015).…”
