Assessment of proximate parameters of both farmed and wild-selected fish species in Bangladesh

Abstract

The present study was designed to analyze and compare the proximate parameters of farmed and wild-selected fish species of Bangladesh including Labeo rohita, Anabas testudineus, Ompok pabda, Heteropneustes fossilis, and Mystus cavasius during November 2023 to April 2024. These specimens were collected from farmed and wild sources in Faridpur district, Bangladesh and kept separately in ice bags and brought into the BCSIR laboratory, Rajshahi for further analysis. The protein, lipid, moisture, and ash contents of wild and farmed fish of each species were estimated as wet matter basis, and standard methods were used for analysis. Considering proximate composition high protein fishes are Rui 18.11±0.26% (farmed), Koi 16.96±0.17% (farmed), Pabda 15.81±0.79% (farmed), Shing 16.09±0.23% (farmed), Gulsha 16.03±0.18 % (farmed); high lipid content fishes are Rui 3.06±0.19% (farmed), Koi 11.63±0.31% (farmed), Pabda 7.19±0.22% (farmed), Shing 4.59±0.15% (farmed), Gulsha 5.68±0.22% (farmed); high ash contents are found in Rui 1.75±0.15% (wild), Koi 4.53±0.35% (wild), Pabda 1.63±0.12% (wild), Shing 2.83±0.11% (wild), Gulsha 2.66±0.05% (wild); high moisture contents are found in Rui 78.04±1.53% (wild), Koi 68.72±0.83% (wild), Pabda 75.73±1.25% (wild), Shing 77.02±2.48% (wild) and Gulsha 77.15±0.58% (wild). After a comparison of both types, it was found that the protein and lipid contents are higher in farmed fishes while the moisture and ash contents are higher in wild fishes. It showed that the farmed fishes are nutritionally superior to the wild fishes considering the protein and lipid content but the wild fishes contained higher ash contents than the farm-raised samples.
