Biochemical Composition of Different Loaches in Bangladesh

Abstract

This study was conducted to determine the biochemical composition of Botia dario and Lepidocephalichthys guntea collected from different regions in Bangladesh. Samples were collected from fishermen during the study period. Fishing activities were done either by dewatering process or by using fishing gears. Different types of gear were used to collect fish samples includes lift net, push net, cast net, and other fishing gear. For B. Dario the moisture content was 68.50%, ash content was 2.72%, crude protein content was 15.50 %, lipid content was 12.21%, and carbohydrate content was 1.07% in wet weight basis and 12.50% moisture, 8.68% ash, 63.2% crude protein, 13.07% lipid, and 0.11% carbohydrate was in dry matter basis. The nutritive components of L. guntea fish were 77.89% as moisture, 3.09% as ash, 16.54% as crude protein, 1.53% as lipid, 0.95% as carbohydrates on a moisture basis, and 10.11% as moisture, 13.84% as ash, 64.70% as crude protein, 6.92% as lipid, 4.43% as carbohydrates on a dry matter basis. The overall study revealed that B. dario and L. guntea are very rich in nutrient composition. All of the information will be helpful for researcher and policy makers for proper conservation and management of these fish.
