随着科学技术的发展,灯光被广泛地用于农业、畜禽和渔业生产,我们设想在养鱼网箱内设置适当的水下光源,延长箱内的光照时间,借以诱集水中浮游生物和空中的昆虫,以增加鱼类饵料和摄食生长时间,夜间由于水中灯光的作用,促使浮游植物光合作用,释放氧气,增加水中溶氧量,适应高密度放养,达到高产的目的。我们在小型静水池塘作了如下的试验。 With the development of science and technology, light is widely used in agriculture, livestock and fishery production. We envisaged to set appropriate underwater light source in the fish cage to extend the light time in the tank to attract plankton in the water and Aerial insects to increase fish food and feeding growth time, due to the role of light in the water at night to promote phytoplankton photosynthesis, the release of oxygen, increasing the amount of dissolved oxygen in water to adapt to high-density stocking, to achieve high yield purposes. We did the following experiment in a small still pond.
