1990年,唐海县西林养殖场利用有效水体1100m~3,总育出健壮虾苗3.5亿尾(折合31.8万尾/m~2),首次突破苗种自供有余,取得了较好经济和社会效益。其主要技术措施如下: 1.充分利用当地水质肥度较高、自然饵料丰富的优势,严格掌握好易于败坏水质的豆浆、蛋黄、微颗粒(DY系列)等人工饵料投量,并尽量满足幼体嗜食、营养价值极高的自然轮虫、美国进口卤幼及盐场卤虫成体等理想天然饵料,促进了各期幼体成活率的提高。
In 1990, Xilin Animal Husbandry in Tanghai County, with an effective water body of 1100m ~ 3, produced a total of 350 million robust shrimp fries (equivalent to 318,000 / m ~ 2), breaking through the shortage of seed for the first time and achieved good economic and social benefits benefit. The main technical measures are as follows: 1. Make full use of the local high water and fat, natural food rich in advantages, strictly control the easy to spoil water quality soybean milk, egg yolk, micro-particles (DY series) and other artificial feed and try to meet larvae Natural rotifers with high dietary value and high nutritive value, and ideal natural feed such as halophila and saltwater imported from the United States have promoted the improvement of the survival rate of all larvae.
