冬季天气寒冷,水温低,鱼类主要集中于池水底层。由于耗氧量增加,易造成底层水体缺氧,使鱼窒息死亡降低成活率。下面介绍几种鱼池冬季补氧的办法。生物增氧浮游生物在进行光合作用时放出的氧,是越冬水体溶氧的主要来源。在冰封前要有意识地注入部分含浮游植物多的肥水,作为引种 Cold weather in winter, low water temperature, fish are mainly concentrated in the bottom water. Due to increased oxygen consumption, easily lead to hypoxia in the bottom of the water, so that the death of fish suffocation to reduce the survival rate. Here are several ways to fish oxygen pond in winter. Bio-aeration Oxygen released by plankton during photosynthesis is the main source of dissolved oxygen in wintering water bodies. In the ice before the conscious injection of some phytoplankton and more fertilizer, as an introduction
