The present study investigates the success of stocking fingerlings of Indian major carps ‐Gibelion catla (Hamilton), Labeo rohita Hamilton and Cirrhinus mrigala Hamilton – to enhance fish yield in 58 small reservoirs in Odisha State, India. Fish stocking and yield data were collected from State Fisheries Department, Odisha. The relationships between area, stocking density and fish yield of different size groups of reservoirs were assessed using the Pearson correlation coefficient (r). Fish yield increased significantly (p < 0.05, t‐test) from 204 kg/ha/year in 2012–13 to 323 kg/ha/year in 2013–14 due to adoption of CBF. The corresponding per capita fish production increased from 398 kg fisher⁻¹ year⁻¹ to 702 kg fisher⁻¹ year⁻¹ benefitting more than 8,000 fisher households. Reservoirs in the size group 100–500 ha showed the highest response of fish yield with respect to stocking of fingerlings. The size of fingerlings at stocking and area of the reservoir had greater impact on enhancing fish yield. Stocking had a profound positive impact on fish yield. This study forms a baseline evaluation of the impact of stocking on small tropical reservoirs in India. It also recommends management measures and discusses issues, and the way forward for sustainable fisheries enhancement in small tropical reservoirs in eastern India.

在印度奥里萨邦以养殖为基础的渔业评估和影响评估，以提高小型水库的鱼类产量

本研究调查了在印度奥里萨邦的58个小型水库中放养印度主要鲤鱼Gibelion catla（汉密尔顿），Labeo rohita Hamilton和Cirrhinus mrigala Hamilton的鱼种成功的方法。鱼存量和产量数据是从奥里萨邦国家渔业部收集的。使用皮尔森相关系数（r）评估了不同大小的水库组的面积，放养密度和鱼类产量之间的关系。鱼类产量显着增加（p  <0.05，t测试）由于采用CBF，从2012-13的204千克/公顷/年到2013-14的323千克/公顷/年。相应的人均鱼产量从398公斤渔民- ¹年^-1增加到702公斤渔民- ¹ 年^-1使8,000多个渔民家庭受益。在100-500公顷大小的水库中，鱼种对鱼种的反应最高。鱼种在放养区和水库面积的大小对提高鱼类产量有更大的影响。放养对鱼类产量产生了深远的积极影响。这项研究形成了对印度小型热带水库放养影响的基准评估。它还建议了管理措施并讨论了问题，以及在印度东部小型热带水库中可持续渔业可持续发展的方法。
