水蚯蚓又名丝蚯蚓、红线虫等,其营养全面,干品含粗蛋白达62%,多种必需氨基酸含量达35%,是饲养多种水生动物的理想饵料。因此,发展水蚯蚓养殖大有前途。在有些地方,利用水田或旱改水田养殖水蚯蚓已取得成功,每667m~2达到2000kg/年以上,而且投资小,易上规模,养殖技术简单,周期短,收益高。现将该技术介绍如下。
Water earthworm, also known as wire earthworm, red worms, etc., its nutrition is comprehensive, dry matter containing crude protein up to 62%, a variety of essential amino acids content of 35%, is ideal for feeding a variety of aquatic animal feed. Therefore, the development of water worms promising. In some places, the use of paddy fields or dry farming waterworms has succeeded in producing watery earthworms, reaching over 2000kg / year every 667m ~ 2. Moreover, the investment is small, the scale is easy, the breeding technology is simple, the cycle is short, and the income is high. The technology is introduced below.
