The northeast Atlantic is said to be an important piece of waters for marine capture.Its inhabiting environment is sensitive to the changes of the Arctic climate.Based on the data of the catch of FAO in the northeast Atlantic from 1950 to 2012,this article analyzes three indexes of 293 exploited marine communities.The three indexes are mTL (the temporal trend in the mean trophic level),FIB (fisheries-in-balance index),TrC (trophic categories). The goal is to provide the basis for further study of how the Arctic climate change influences its fishery resources. According to our research,the mTL had greatly decreased at a rate of 0.02T Lper year(r=-0.614;P< 0.01),from 3.71(1950)to 3.57(2012).Meanwhile,the FIBindex had been speeding downhill for the last 8 years.Moreover,the mTLof the catch in the northeast Atlantic is highly related to the climate change(such as rise of sea surface temperature,North Atlantic Oscillation and shrinking sea ice and so on).It is obvious that high catches came up in the anomalies year of the sea surface temperature:1956,1976 and 1997.This paper analyzes changes of trophic level to catch in the northeast Atlantic,so as to provide the basis of studying the relationship between fish composition and climate change in the northeast Atlantic.In addition,it also offers a theoretical basis for the sustainable development of fisheries resources.
