Fisheries sector contributes about 5.3% to GDP and about 6% of the export earnings of Bangladesh. There are about 4.1 million ha of inland water bodies in Bangladesh. However, over last two decades the catch from inland capture fishery has decreased due to filling of wet lands and other anthropogenic reasons. Accordingly, the production of inland fish has decreased not only for the decrease of water bodies but also due to irrational catch of fish fries, brood fishes and use of current nets for fishing. Significant responses from the fisheries entrepreneurs have not been received for the small loan scheme of the Bangladesh Bank. The bank could not disburse more than Tk. 500 million under the scheme. The total revolving credit under the scheme was Tk. 1,000 million with the assistance from the World Bank. The business houses having fixed assets of value not more than Tk. 10 million will be eligible to borrow from this fund. About Tk. 0.2-5.0 million can be borrowed as term loan and working capital from Bangladesh Bank through commercial banks. The loan was given to the commercial banks at 5% interest (bank rate) and the commercial banks shall also bridge finance to the entrepreneurs at a lower rate of interest. Working capital time limit is for a maximum of 1 year with half yearly rest, mid-term loan maximum of 3 years in 5 installments and with 6 months grace period and long-term loan maximum of 5 years in 9 installments with 6 months grace period.

This study sought to improve the baseline knowledge of the fisheries of Lake Nasser and to make recommendations for the improved management of the fisheries, including stock assessment. This review draws heavily from the most recent reviews of Lake Nasserr and its fisheries, including van Zwieten et al. (2011), Habib et al. (2014) and Habib (2015). It is supplemented with findings from the field study described in the final technical report, Lake Nasser fisheries: Recommendations for management, including monitoring and stock assessment (Halls 2015).

Long-term trends in the elasmobranch assemblage of Elkhorn Slough, Monterey Bay, California, were analyzed by documenting species composition and catch per unit effort (CPUE) from 55 sport fishing derbies that occurred during May, June, and July, from 1951 until 1995. The most abundant species (bat ray, Myliobatis californica; shovelnose guitarfish, Rhinobatos productus; and leopard shark, Triakis semifasciata) were also analyzed for size-weight relationships, trends in size class distribution, stage of maturity, and sex ratios. Changes in species composition over the course of the derbies included the near complete disappearance of shovelnose guitarfish by the 1970’s and a slight increase in the abundance of minor species (mainly smoothhounds, Mustelus spp., and thornback, Platyrhinoidis triseriata) starting in the mid 1960’s. The relative abundance of bat rays in the catch steadily increased over the years while the relative abundance of leopard sharks declined during the last two decades. However the average number of bat rays and leopard sharks caught per derby declined during the last two decades. Fishing effort appeared to increase over the course of the derbies. There were no dramatic shifts in the size class distribution data for bat rays, leopard sharks, or shovelnose guitarfish. The catch of bat rays and leopard sharks was consistently dominated by immature individuals, while the catch of shovelnose guitarfish was heavily dominated by adults. There was evidence of sexual segregation in either immature or mature fish in all the species. Female bat rays and shovelnose guitarfish were larger than their male counterparts and outnumbered males nearly 2:1. Female and male leopard sharks were more nearly equal in size and sex ratio. Changes in species composition are likely due to fishing pressure, shifts in the prevailing oceanographic conditions, and habitat alteration in Elkhorn Slough. The sex ratios, stage of maturity, and size class distributions provide further evidence for the theory that Elkhorn Slough functions as a nursery habitat for bat rays and leopard sha
