河北大学生物系青年讲师王安利等承担的河北省科委、河北省畜牧水产局《中国对虾高产生态因子养殖技术》项目最近喜结成果,并通过省级鉴定。专家认为该项成果在虾类无机盐及维生素等研究方面达世界先进水平并居国内领先地位。其成果的推广,可促进我国养(?)业的发展,使我国对虾养殖业跨上一个新台阶。近几年来,我国对虾养殖业发展迅速,据1989年统计,我国对虾养殖面积达220万亩,年产量18万吨,居世界首位。但另一方面,我国养殖对虾存在着个体小、质量差、抗病力弱,亩产量低等问题,增加产量的主(?)式是增加投喂天然饵料,因而近岸海洋生物资源受到掠夺性采捕,在一定程度上影响(?)海洋生态系统的稳定性。承担《中国对虾高产生态因子养殖技术》的王安利等同志,
Wang Lili, a young lecturer in biology department of Hebei University, took part in the project of Hebei Province Science and Technology Commission and Animal Husbandry and Fishery Bureau of Hebei Province recently. Experts believe that the results in the shrimp inorganic salts and vitamins and other aspects of research reached the world advanced level and ranking the leading domestic position. The promotion of its achievements can promote the development of China’s (?) Industry and make China’s shrimp culture industry reach a new stage. In recent years, China shrimp farming industry has developed rapidly, according to 1989 statistics, China’s shrimp farming area of 220 mu, annual output 180,000 tons, ranking first in the world. However, on the other hand, there are some problems in farmed shrimp in our country, such as small size, poor quality, weak disease resistance and low yield per mu. The main (?) Formula for increasing production is to increase the feeding of natural bait, Sex harvesting, to a certain extent, affects the stability of marine ecosystems.
