dc.description.abstract	The thesis focuses on three specific challenges for the seafood industry: (1) the quality and capacity of national institutions; (2) the importance of environmental factors for aquaculture production; and (3) how to monitor and, hopefully, manage fisheries with few and uncertain observations (data-poor fisheries). Each challenge has been studied empirically using proper methodologies and presented in individual papers.	en_US

dc.description.popularabstract	This thesis focuses on the importance of some of these factors. The first factor studied is the role of institutions in aquaculture production (Paper 1). This was studied by analysing the relationship between the annual growth rate in aquaculture production of the major aquaculture producing countries and the quality of institutions in those countries over the last three decades (1984–2013) using econometric models. The second factor studied is the environmental challenges, i.e. how a changing climate may affect aquaculture production in the Asian region (Paper 2). The study analyses the vulnerability and resilience of fresh and brackish water aquacultures, mainly carp, tilapia, catfish, gourami, shrimp, crayfish, and crab production in major Asian producing countries. The third factor is related to fisheries and the lack of information about their stock status of fisheries. How can crucial information be obtained from data-poor fisheries (Paper 3) from a management perspective? The stock status of major Indian ocean fisheries has been evaluated using a proposed simple stock assessment method. The main findings of the three papers are to be used to discuss the growth and development of Asian seafood production and Sri Lankan seafood industry from a future perspective.	en_US
