近几年来淡水养鱼业发展很快,随着养鱼技术的不断提高,渔业机械也应运而生。为了满足生产需要,现将常用的增氧机械、饲料加工机械和水力挖塘机械简介如下: (一)增氧机械:随着鱼业生产发展的要求,水中溶氧仅靠浮游植物的光合作用和风力等自然因素的增氧作用,已不能满足鱼类对氧的需求。增氧机已逐步成为高产鱼塘必备的机具。它不仅可以预防和解救鱼类浮头,提高放养密度,增加施肥和投饵量,而且还可以改善水质,促进浮游
In recent years, the rapid development of freshwater fish farming, with the continuous improvement of fish farming, fishery machinery has emerged. In order to meet the production needs, aerobic machinery, feed processing machinery and hydraulic digging pond machinery commonly used are as follows: (A) aerobic machinery: With the requirements of the development of fish production, dissolved oxygen in water only rely on phytoplankton photosynthesis And wind and other natural factors of oxygen, can no longer meet the fish’s oxygen demand. Aerator has gradually become a high-yielding fish pond necessary equipment. It can not only prevent and rescue fish floating head, increase stocking density, increase fertilization and feeding amount, but also can improve water quality and promote floating
