Abstract/ Executive Summary:

The study was carried out during the period from July 2008 – June 2011. Objective of the study was to asses edible portion of small fish product after dressing. The range and mean ± SD total length (TL) and total weight (TW), the weight after dressing (WAD) was measured from the group weight. G. giuris having the maximum mean TL 106.4 ± 18.29 mm, the ratio between the edible and non edible portion was found as 1 : 0.204. C. fasciata having the maximum mean TL 75.8±10.10 mm, the ratio between the edible and non edible portion was found as 1:0.188 whereas, P. ticto same sized fish mean TL = 67.9±16.40mm have the mentioned ratio as 1:0.380. After dressing the percentage of edible flesh portion was 84.15 for C. fasciata and 72.49 for P. ticto. E. vacha (mean TL = 62.95 ± 13.47mm) is a smaller fish, the ratio between the edible and non edible portion were 1:0.112 and percentage of edible portion was 89.86%. C. soborna (mean TL = 17.85±5.58mm) is a smaller clupeid fish. The ratio between edible and non edible portion were 1:0.025 and after dressing and washing percentage of edible flesh portion was 97.54% for C. soborna.

Program Area: Socio-economic and Policy

Commodity: Fish

Objectives:

The present attempt was made to asses edible portion of small fish product after dressing.

Methodology:

The study was carried out during the period from July 2008 – June 2011. Samples of Glossogobius giuris, Colisa fasciata, Puntius ticto, Eutropiichthyes vacha, Corica soborna and some mixed fishes (Chanda nama, C. ranga, Amblypharyngodon mola, Mastacembelus pancalus, Xenentodon cancila) were collected randomly from different fish markets and local landing centre of Rajshahi city. The fishes were washed with clean water and the excess water was soaked with kitchen tissue. First, the whole body weight of the samples were recorded. Then the fishes were cut off and the scales were scrapped off. Viscera was removed and the fish was weighted again. Weight of all the wastes (viscera, fins, scales etc.) were taken. The percentage of the flesh after dressing were calculated and the ratios of the edible parts were determined.
