夏季是鱼类生长旺盛季节,抓好夏季养鱼的日常管理对于提高全年的鱼产量至关重要。网箱养鱼夏季管理应着重抓好以下几个方面。一、网箱的设置与调整。夏季是主汛期,放置网箱的水域水位会受雨水和洪水的影响,网箱应随着水位的升降而调整。对于水位变化较小的水域,放养网箱也定期移动,原因是夏季水温高,鱼类代谢旺盛,饵料残渣和鱼体排出粪便大量积累在网箱底部分解,耗氧量大,水质变坏,容易引起箱内鱼类的缺氧,更易感染鱼病。尤其是设
Summer is a period of vigorous growth of fish, and a good grasp of the day-to-day management of summer fish culture is crucial to improve fish production throughout the year. Cage fish management in summer should focus on the following aspects. First, the cage settings and adjustments. Summer is the main flood season, placing cages in the water level will be affected by rain and floods, cages should be adjusted with the water level rise and fall. For waters with small changes in water level, the stocking cages also periodically move due to the high water temperature in summer and the vigorous metabolism of fish. Large amounts of excrement excreted by food residues and fish accumulate at the bottom of cages to decompose, with large oxygen consumption and deteriorating water quality. Easily lead to hypoxia of fish in the box, more susceptible to fish disease. Especially set
