随着名优特新水产品和观尝鱼类生产的迅速发展,其苗种阶段的最适活饲料水蚯蚓的需要量也越来越大。显然,仅靠天然出产的那点资源是远远不够的,也必须走人工培育水蚯蚓这条必然之路。下面介绍其中的几个关键问题。一、建池。应选择有水源保证的地方建池,如能引入无毒害的生活污水则可降低生产成本。水蚯蚓培育池一般以长条形为好,池宽1～1.5米、长5～30米、深0.25
With the rapid development of famous special new aquatic products and tasted fish production, the demand of earthworm, which is the most suitable live feed for seed stage, is also increasing. Obviously, it is far from enough to rely solely on natural resources and we must take the necessary path of artificial cultivation of water earthworms. Here are some of the key issues. First, build the pool. Should choose a water source to ensure the construction of the pool, if the introduction of non-toxic domestic sewage can reduce production costs. Water earthworm breeding pool is generally long strip shape is good, the pool width of 1 to 1.5 meters, 5 to 30 meters long, 0.25 deep
