Sumithion is an organophosphate insecticide, extensively used to remove tiger bug from aquaculture ponds prior to the release of fish larvae. Its usage in aquaculture may initially assist in insect eradication; however, the harmful effects of sumithion may surpass the beneficial effects and may be alarming for the farmed fish and other aquatic organisms. This study summarizes the consequential effects of sumithion on the natural productivity in aquaculture ponds, and early development, physiological response, and reproductive functions of the farmed fish. Studies have found that sumithion adversely affects the natural production of phytoplankton, zooplankton and benthos, and reduces the hatching success with increased mortality, and morphological alterations in fish embryos and larvae. Fish haematological and biochemical alterations are also reported to be induced by the exposure to sumithion, as are variety of histopathological alterations and reproductive dysfunctions in exposed fish. Overall, this study is the first comprehensive overview of any insecticide which may advance our understanding of the rational and restricted use of insecticide in aquaculture operations.

Sumithion 在水产养殖中的使用：受益还是丧失？

Sumithion 是一种有机磷杀虫剂，广泛用于在鱼幼虫释放之前从水产养殖池塘中去除虎虫。它在水产养殖中的使用最初可能有助于消灭昆虫；然而，sumithion 的有害影响可能超过有益影响，并且可能对养殖的鱼类和其他水生生物造成威胁。本研究总结了 sumithion 对水产养殖池塘自然生产力以及养殖鱼类的早期发育、生理反应和繁殖功能的后续影响。研究发现，sumithion 对浮游植物、浮游动物和底栖动物的自然产生产生不利影响，并随着死亡率的增加以及鱼类胚胎和幼虫的形态改变而降低孵化成功率。据报道，暴露于 sumithion 也会引起鱼类的血液学和生化改变，以及暴露于鱼类的各种组织病理学改变和生殖功能障碍。总体而言，这项研究是对任何杀虫剂的首次全面概述，这可能会促进我们对水产养殖作业中杀虫剂的合理和限制使用的理解。
