A study was conducted to evaluate some commercial fish feeds available in Bangladesh comparing the nutrient content through chemical analysis. The commercial fish feeds collected from the markets were Mega Feeds Limited (MF), Jayson Agrovet Limited (JF), Quality Feeds Limited (QF), ACI Agrovet Private Limited (ACI), Paragon Agro Limited (PF). Proximate composition such as moisture, crude protein, crude lipid, ash, fibre and NFE (nitrogen free extract) were analysed. In general, there was no large variation between analysed and company declared nutrient contents of different feeds except the protein and lipid content of some feeds. However, two pangas feeds such as starter and grower of MF had much lower protein content (31.20 % and 26.46 %) compared to 35% protein value for both declared by the company. Similarly, large (more than 5%) differences between the analysed and company declared protein content was observed in case of carp starter and grower feeds of QF. On the other hand, analysed protein content of all feeds of ACI was more than that declared by the company except for grower-II feed which had slightly lower (1%) protein compared to the company declared value. Pangas feeds (grower I and II) of PF had about 2% lower protein than the company declared value. The analysed lipid contents of all feeds were higher than the company declared values except Sonali (G) feeds of QF which had about 1-2% less lipid content compared to the company declared value. Moisture content of most of the feed was around the company given maximum values except Surovi (S) of QF that was 3% higher. Fibre contents of different feeds analysed were much higher (3-5%) than the company declared values. The results of the study showed that on the basis of nutrient content feeds from ACI Agrovet Private Limited is better than other feeds.
