水蚯蚓隶属环节动物门寡毛纲,是淡水底栖生物的主要类群之一。其干物质中蛋白质高达70％以上,各种必需氨基酸种类齐全,含量丰富,具有较高的营养价值。是鲤鲫鱼、泥鳅、黄鳝、稚鳖、塘虱鱼、淡水白鲳以及观赏鱼类等名特优水产品的最佳活食。现介绍水蚯蚓的培育技术如下: 水蚯蚓的最佳生态条件:水温22℃—29℃,溶氧为饱和度的30％—60％,含有丰富有机质,有底泥供固着生活。一、培养池及培养基。选择水源良好处建池,最好是水泥砖结构,池底敷三合土。池长3—5m,宽1m,深0.2m,池两
Water earthworm belongs to the order of the section of the door of the oligopoda, is one of the major groups of freshwater benthic organisms. Its dry matter in protein up to 70%, all kinds of essential amino acids complete, rich in content, with high nutritional value. Is the carp crucian carp, loach, eel, larvae, pond louse, freshwater pomfret and ornamental fish and other famous special aquatic products the best live food. The introduction of aquatic earthworm cultivation techniques are as follows: The best ecological conditions of water earthworms: water temperature 22 ℃ -29 ℃, dissolved oxygen saturation of 30% -60%, rich in organic matter, sediment for the fixed life. First, the pool and culture medium. Select a good source of water to build the pool, the best is the cement brick structure, the end of the pool deposited trigeminal. Pool length 3-5m, width 1m, depth 0.2m, pool two
