Post-harvest handling and quality loss of two major carps in the distribution channel of Jashore Region, Bangladesh
Abstract
The study was undertaken to investigate the post-harvest loss of rohu (Labeo rohita) and mrigal (Cirrhinus cirrhosis) in the different distribution channels of the different fish markets in Jashore, Bangladesh for getting information on quality deterioration and existing practices. The sensory evaluation method was adopted to gather information about quality loss and existing handling conditions. The quality loss was observed through the different stakeholder levels because of improper handling, and transportation procedures. For rui fisherman supplied fish to aratdar at 3.57% quality loss, further 5.46% and 9.4% loss was observed through retailer and consumer respectively. For mrigal fisherman supplied fish to aratdar at 3.57% quality loss, further 5.47% and 9.05% loss was observed through retailer and consumer respectively. DPs (Defect Points) were higher in June–July which indicates that temperature rise causes more quality loss of fish. The ice ratio of fish: ice was 1:1 in summer and 2:1 in winter. Fisherman used only 25% ice whereas aratdar never used ice and retailer used 62.5% ice during transportation. The more quality loss of fish the more ice was used. Fisher transporting fish by the van, pickup, nosimon, rickshaw and the percentages were 10%, 14%, 70%, 6% respectively. Bad handling practices due to transportation and in markets also caused quality deterioration. Post-harvest loss of fish is not taken under consideration. The highest defect point was 2.7 at the retailer level because of long term exposure to open air. So, the study is needed for the development of knowledge in fishing, handling and processing, selling and transporting.
