Abstract：
The increasing population and plateaued capture fishery landings have led to increasing demand for aquaculture products. However, environmental challenges are critical barriers to the sustainable development of aquaculture in developing countries. This review critically evaluates the environmental barriers facing aquaculture development in Bangladesh while laying out a roadmap for future development and spatial planning. An increase in the area used for aquaculture most often results in increasing pressure on natural resources such as land, water, energy, and the sources used for feed. Some of the negative externalities that this review focuses on are effluent discharge, the spread of diseases, and conflicts over land use with other ecosystem users. A way forward is to internalize these negative externalities and their costs into production decisions by farmers. Formulation of incentive-based pragmatic regulations can pave a forward path to increased environmental sustainability.
摘要：
不断增加的人口和稳定的捕捞渔业登陆导致对水产养殖产品的需求增加。然而,环境挑战是发展中国家水产养殖可持续发展的关键障碍。这篇评论批判性地评估了孟加拉国水产养殖发展面临的环境障碍，同时为未来的发展和空间规划制定了路线图。用于水产养殖的面积增加通常会导致对土地等自然资源的压力增加，水,能源,以及用于饲料的来源。本综述关注的一些负外部性是污水排放，疾病的传播,以及与其他生态系统使用者在土地利用方面的冲突。前进的道路是将这些负外部性及其成本内部化为农民的生产决策。制定基于激励的务实法规可以为提高环境可持续性铺平道路。
