1.施肥和投饲料:为了促使鱼类天然饵料的不断繁殖生长,保证池鱼撮食的需要,各类鱼池特别是以花白鲢为主的鱼池,都应适当追施肥料。由于这阶段天气热,水温高,有机物分解快,浮游生物繁殖量多,鱼类耗氧多,加上气候多变,水质容易变化,所以一次施肥量不宜过多,要采取少施勤施的原则。应根据天气,水色和饲养鱼类的品种决定施肥量。如天气晴朗可适当多施,雨天或闷热天气应少施或不施肥;水色清淡,呈淡黄色或淡绿色,透明度大要多施,水色呈褐绿,油绿或褐色,透明度在30厘米左右可少施或不施肥;以饲养花白鲢、罗非鱼或草鱼的鱼池要少施。施肥时要避开食场。
1. Fertilization and feeding feed: In order to promote the continuous growth of natural fish food, to ensure the need for fish food, all kinds of fish ponds, especially in the silver carp-based fish ponds, should be topdressing fertilizer. Due to the hot weather, high water temperature, rapid decomposition of organic matter, multiplication of plankton and more oxygen consumption in fish, coupled with the change of climate and water quality, the amount of fertilizer should not be too much. in principle. The amount of fertilizer should be determined according to the weather, aqua and breed of fish. Such as the weather can be appropriate and more sunny, rainy or hot weather should be less or no fertilization; aqua light, pale yellow or light green, transparency and more facilities, aqua brown, green or brown, transparent about 30 cm Less or no fertilization; to feed the silver carp, tilapia or grass carp fish pond to be less applied. Fertilizer to avoid the food court.
