Studies on selectivity of penaeids were carried out by comparing the catches of the conventional two-seam overhang trawl with that of experimental two-seam overhang trawl having square mesh panels of 45 mm mesh size in the forward part of upper belly and 28 mm mesh size in the cod end. Alternate trawling technique was used by maintaining similarity in towing direction, towing duration, speed and depth of operation to minimize possible errors between the trawls. The results revealed that the experimental trawl caught less quantity of juvenile penaeids than that of conventional trawl having diamond mesh webbing in the body and the cod end. The by-catch was also reduced considerably indicating that the new gear would be helpful for the better management of penaeids resources.Keywords

For evaluating sustainable development in today's scenario, empowerment of target community is imperative just to take their own decision and to know the pattern of equitable distribution of benefit derived from any development programme like fisheries or aquaculture in order to achieve a quality life. The findings of the study revealed that woman empowerment was positively and significantly associated with the knowledge level of beel users at 1% level of probability. So it can be said that empowerment helps one to improve his or her living standard. Hence empowering the women to take decision on different fisheries and aquaculture activities is regarded as one of the most important inputs for sustainable development of beel fisheries.Keywords

Investigations were carried out to study the women engaged in different fishery management practices and to identify independent variables, which are related with the dependent variables, viz., decision making and supervision of women in fish culture in Dakshin Dinajpur district of West Bengal. Randomly selected 120 fisherwomen revealed that majority of them participate in different management practices like application of mohua oil cake (70%), liming (87.5%), application of organic manure (89.16%), and application of inorganic fertilizers (62.5%) and regular netting operation (82.5%). The findings revealed that out of twelve variables only six variables, namely, age, area of the ponds, education, family educational status, economic status and aspiration were significantly correlated with decision making process of women in fish culture. The findings also revealed that out of twelve variables only three variables, namely, age, economic status and aspiration were significant at 0.01 level of probability.Keywords

While conducting fishery resource surveys and efficiency studies on estuarine fishing gears of West Bengal during 2002-03 and 2003-04, an attempt was made to inventorise indigenous fishing gears of Hooghly-Matia estuarine ecosystems of West Bengal. This forms the basis of the present communication. In 1906, Sir K. G. Gupta (1908) undertook investigations on the fisheries of the province of Bengal. Since then, several workers have studied the fish and fisheries resources of Hooghly-Matla estuaries (Hora, 1949; Pillay and Ghosh, 1962; Saha, 1970; Mitra et al, 1997; Pramanik and Nandi, 2004). However, very little work is done on fishing gears of this region (Saha, 1970).- Reduction of By-Catch in Two-Seam Overhang Trawl Using a Square Mesh Panels in Forward Part of Upper Belly and Codend

Reduction of by-catch in two-seam overhang trawl was studied by using a square mesh panels in forward part of upper belly and codend and comparison made with thai of the conventional two-seam overhang trawl. Fishing cruises were carried out randomly at depths of between 24 m and 34 m isobaths in the inshore waters of Mangalore coast. Alternative hauling technique was followed for maintaining similarity in towing direction, duration, speed and depth of operation to minimize the possible errors between the trawls. The results showed that the average by-catch was about 5.5 times lesser in two-seam overhang trawl using a square mesh panels in forward part of upper belly and codend than conventional twoseam hang trawl. However, the difference m reduction of by-catch in both conventional as well as experimental trawls was not found to be statistically significant.Keywords
