Abstract

Fish seed are important for the growth of aquaculture in Bangladesh, but there are many challenges associated with supplying quality fish seed. This review evaluated the current level of production, issues and challenges that are affecting the production of fish seed in Bangladesh. The fish hatchery was found to be the major contributor in terms of fish seed production. Out of 671 metric tons of fish seed produced in 2020–2021, above 99% were from hatcheries. Freshwater finfish hatcheries have expanded over the last 30 yr, and are distributed throughout the country, but there is no commercial hatchery for coastal and marine water finfish species in the country. Shrimp and prawn hatcheries are concentrated in Cox's Bazar and the greater Jassore regions, respectively, while crab culture is entirely dependent on wild capture. Crablets are collected from nature, which has a devastating impact on biodiversity and wild stocks. The fish seed value chain is multidirectional and interlinked, and intermediaries dominate the supply chain. Disease outbreaks and indiscriminate use of chemicals are major concerns in fish seed production. Management strategies such as the introduction of certification, training programs, technology transfer, access to credit, and implementation of the law could improve the quality and productivity of fish seed in Bangladesh.

期刊介绍： Aquatic Living Resources publishes original research papers, review articles and propective notes dealing with all exploited (i.e. fished or farmed) living resources in marine, brackish and freshwater environments. Priority is given to ecosystem-based approaches to the study of fishery and aquaculture social-ecological systems, including biological, ecological, economic and social dimensions. Research on the development of interdisciplinary methods and tools which can usefully support the design, implementation and evaluation of alternative management strategies for fisheries and/or aquaculture systems at different scales is particularly welcome by the journal. This includes the exploration of scenarios and strategies for the conservation of aquatic biodiversity and research relating to the development of integrated assessment approaches aimed at ensuring sustainable and high quality uses of aquatic living resources.
