山东烟台地区莱阳淡水养殖试验场在一九七二年催产季节从海阳里店水库(中型水库,距该场110华里)捕捞鲢亲鱼56组,获卵2155万粒,出苗831万尾。从莱阳小平水库(小型水库,距该场30华里)捕捞鳙亲鱼7组,获卵615万粒,出苗359万尾。现将该场在生产实践中的几点经验介绍如下:1.从水库捕捞亲鱼立即催产,使其自然产卵,如果全部是水库捕起的雌雄亲鱼搭配,在该场试验情况下不受精,若搭配部分池塘培育的雄亲 Shandong Laoyang Freshwater Aquaculture Experimental Site in Shandong Province in the seasons of 1972 induced 56 species of silver carp and broodstock from Haiyanglidian Reservoir (medium-sized reservoirs, 110 li in this field), with 21.55 million eggs and 8.31 million emerges. From Laiyang Xiaoping Reservoir (a small reservoir, 30 li from the site), 7 groups of anchovy catches were harvested, with 6.15 million eggs and 3.59 million sprouts. Now the field experience in the production of a few experiences are as follows: 1 from the reservoir fishing broodstock immediately oxytocin, so that it naturally spawns, if all the reservoirs captured male and female fish in the test case is not fertilized, If with a part of the pond breeding male
