Comparative study on the nutritional composition of native Koi and cultured Thai Koi (Anabas testudineus) in Bangladesh

The study was carried out to analyze and compare the nutritional composition of native and Thai Koi (Anabas testudineus). The moisture, protein, lipid, carbohydrate, ash, and fiber contents were estimated in wet and dry matter basis of the samples. In wet matter basis, the mean value of moisture, lipid, protein, ash, fiber and carbohydrate were found as 67.20±2.78%, 7.84±1.01%, 15.60±0.70%, 6.81±1.34%, 1.33±0.18% and 1.23±0.10% respectively in native Koi while it was 68.72±5.27%, 7.88±2.01%, 16.14±2.18%, 5.30±0.33%, 1.02±0.25% and 0.87±0.57% respectively in Thai Koi. On the other hand, in dry matter basis, the mean value of lipid, protein, ash, fiber and carbohydrate were found as 32.80±2.78%, 23.85±1.08%, 47.63±1.88%, 20.64±2.33%, 4.09±0.90% and 3.78±0.62% respectively in native Koi while it was estimated as 31.28±5.27%, 25.11±2.10%, 51.75±1.75%, 17.10±1.84%, 2.94±0.70% and 2.50±1.63% respectively in Thai Koi. The study revealed that cultured Thai Koi contains higher nutrients than native Koi.
