By catch and discards are serious problem of fishing industry driving to the re-duction of resources and have negative impact on biodiversity. The diverse biota of the largest delta, mangrove forest Sundarbans are utilized to a large extent as food and liveli-hood by the stakeholders. Tiger prawn seed collection is a key resource supply of the liveli-hood for Indian Sundarbans people. In course of the seed collection, assorted samples of non-target juveniles of fish species are destroyed as by-catch due to non -selective fishing gears and push nets. A total of 17 individuals, containing seven orders, ten families, were characterized. The diversity of the fish species ranged between 2.45 and 2.73 with corre-sponding evenness of 0.93 and 0.98. Among the fish species the dominant species was Stolephorus dubiosus while Pseudapocryptes elongatus had the lowest abundance in the samples revealed through the non-metric multidimensional scaling (NMDS). Station Kan-tamari, assessed most extreme number of prawn seed assortment during July - September, followed by Gosaba and Golabari. This study underscore the need to embrace suitable by-catch decrease gadgets in shrimp fishery, in addition requirement of fisheries the board guidelines in request to secure the non-target assets.
