河蚌是培育珍珠的物质基础。近几年来,我国珍珠养殖业发展很快,致使蚌源不足。为满足珍珠养殖对三角帆蚌的需要,不少地方进行了人工繁殖三角帆蚌的生产。生产中所用的中间宿主——黄(鱼桑)鱼(或其它鱼类),因其营底栖生活,资源分散,难以捕捉,所需成本也较高(每斤黄(鱼桑)鱼高达2～3元)。每尾黄(鱼桑)鱼以寄生500～1,000只钩介幼虫计,若生产100万只幼蚌,需准备1,000尾黄(鱼桑)鱼(约200～300斤)。所以到生产季节往往因为没有足够的黄(鱼桑)鱼而影响生产。在饲养过程中要投饲料,稍不注意会造成鱼死蚌亡。为此,我们采用微孔泡沫塑料,代替黄(鱼桑)鱼进行三角帆蚌人工繁殖的尝试。已初获成效。现将试验情况和结果报告如下。
Mussel is the material basis for cultivating pearl. In recent years, the rapid development of China’s pearl aquaculture industry, resulting in lack of mussel. In order to meet the pearl breeding needs of the Hyriopsis cumingii, in many places, artificial reproduction of Hyriopsis cumingii production. The intermediate host used in the production of yellow (fish mulberry) fish (or other fish), due to their benthic life, scattered resources, difficult to capture, the cost is also high (catty fish 2 to 3 yuan). Each yellow (fish) fish with parasitic 500 to 1,000 hookworm larvae count, if the production of 1 million young mussels, need to prepare 1,000 yellow (fish) fish (about 200 to 300 pounds). As a result, production is often affected by the lack of enough yellow (fish, squid) fish during the production season. Feeding in the feeding process, a little careless will cause dead fish clam. To this end, we use microporous foam, instead of yellow (fish mulberry) fish Artificial propagation of Hyriopsis try. Has achieved initial success. Now the test results and results reported below.
