每年初夏季节,渤海内各类渔虾大量集中在近海沿岸产卵繁殖。国家为了保护渔业资源,通过法津手段设置了6月20日～8月20日禁渔期,但又规定,有重要科研试验的渔船,准许在禁渔期内进行有限的试验性捕捞。由于繁殖期间鱼虾类大量聚集在近海沿岸地区,在这种高密度下,进行渔业生产可谓事半功倍。以唐山为例.禁渔期试验渔民的收入为全年(禁渔期除外)收入的总和。××县一条80Hp渔船,1992年7月1O日～8月1日毛收入4万多元。最多时一天卖货3000元。1987
In the early summer of each year, a large number of various types of shrimp in the Bohai Sea are concentrated in the offshore coast for egg breeding. In order to protect fishery resources, the state has set a closed fishing season from June 20 to August 20 through the method of legal aid. However, it also stipulates that fishing vessels with important scientific research and experiments will be allowed to conduct limited experimental fishing during the closed fishing season. Due to the large numbers of fish and shrimps gathering along the coastal areas during breeding, fishery production can be more effectively done at this high density. Taking Tangshan as an example, the income of fishermen during the fishing season was the sum of the income for the whole year except the fishing season. × × County 80Hp fishing boats, 1992 July 1O ~ August 1 gross income of more than 40,000 yuan. Up to 3,000 yuan a day selling. 1987
