Study on Spatial-temporal Distribution of Fishing Ground for Morocco Bottom Trawling Fishery
摘要
Abstract
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.关键词
