通过在同一池塘中放养猫（Catla catla）、野唇鱼（Labeo rohita）、鲤鱼和银鱼，研究了它们之间的食物竞争。此外，鱼的生长和生产性能进行了比较，在鲤鱼混养系统添加和不添加银倒刺。结果表明，银鱼与本地和外来鲤鱼都存在天然食物竞争。在半集约化混养条件下，添加银鱼对鲤鱼的生长和生产具有增效作用，但不影响红鲤和罗氏沼虾的生长和生产。有一个显着更高的组合净产量（1793公斤/公顷），实现了四个物种，这是25%以上的净产量从三个物种没有银倒钩。
Food competition among catla (Catla catla), rohu (Labeo rohita), carp and silver barb was evaluated by stocking these species in the same pond. Also, fish growth and production performance was compared in the carp polyculture system with and without addition of silver barb. Results showed that silver barb competed with both native and exotic common carp for natural food. In semi-intensive polyculture with fertilizers and supplemental feed, silver barb had a synergistic effect on the growth and production of common carp without hampering the growth and production of catla and rohu. There was a significantly higher combined net yield (1793 kg/ha) achieved with four species, which was 25% higher than the net yield from three species without silver barb.
