Publication Description :
A study was conducted on the types of fishing gears used; catch assessment survey (CAS) and species composition of the Lohalia River adjacent to the sadar upazilla of Patuakhali district. Various types of fishing gears were found to operate in this river; they were broadly classified into 2 groups, such as nets and traps. A total of 8 types of nets and 2 types of traps were recorded. A total of 43 species of fish were identified in the catches of different gears used by the fishermen. Among the different types of nets, the highest number of species (28) was recorded in the catches of Behundi jal, which was followed by Ber jal (26) and relatively less number of species (5) were recorded in the catches of Sain jal. The reasons behind the fluctuation in the number of fishing gears used in the river are availability of fish. In July to October the water level of the river remains high, so the abundance of fish remains also high. Again, in this period different fish breed and different marine species also come with high tide. With the freshwater species different marine species of fish are also available in Lohalia River. Some marine species are available almost all the year round and some species come in the river during their breeding seasons, especially rainy season. Fishing by using traps is done mainly during July to September when the water level remains high. During high tide the water enter into the adjacent canals and the fishermen set the traps in the mouth of the canals. The traps are mainly used at nigh t.
