摘  要：
根据2012—2015年11月至翌年3月(冬季渔汛)上海某渔业公司在摩洛哥海域的底拖网渔船生产统计数据,采用频度分析法和渔场重心法对冬季渔汛底拖网作业渔场时空分布进行研究。结果表明,摩洛哥冬季渔汛底拖网作业渔场分布在15.0°—18.0°W、20.0°—26.0°N海域,经度方向上主要集中在15.5°—16.5°W和17.0°—17.5°W范围内,纬度方向上主要集中在21°—22°N和23°—25°N海域,其产量所占比率在85%以上。渔场重心呈现出规律的分布,基本上分布在1个经纬度范围内。11月份渔场重心分布在16.63°W、23.20°N附近海域;12月—翌年1月份分布在16.53°W、23.03°—23.09°N海域;2月份分布在23.21°N、16.48°W附近海域;3月份分布在23.56°N、16.33°W海域。

摘  要：
The current study investigated the spatial-temporal distribution of fishing ground for bottom trawling fishery in winter fishing season using methods of frequency analysis and fisheries center of gravity based on production statistics fished by bottom trawlers from Shanghai fisheries company in Moroccan sea during 2012 to 2015. The results revealed that the distribution of bottom trawling fishery in winter fishing season is located in the waters of 15.0- 18. 0 W and 20.0°N-26. 0 N in Morocco,mainly concentrated in the 15.5°-16.5°W,17.0- 17.5 W 17.40-17.60 W and 21 – 22 N,23-25 N,in which the catch occupied above 85% of the total catch. The results indicated that the fishing center of gravity presents the regularity of distribution, basically distributed within a latitude and longitude. The fishing center of gravity are mainly distributed in the waters near 16.63°W and 23.20 N during January,in the waters near 16.53 W and 23.03- 23.09 N during December and January,in the waters near 23.21 N and 16.48 W during February,and in the waters near 23.56 N and 16.33 W in March. Understanding the spatial-temporal distribution of fishing ground will benefit the seasonable fishing in the Morocco marine fisheries.
