Abstract：Based on the catch of southeast Atlantic from 1950 to 2019,FAO,we used dominance analy-sis to analyze the catch and catch species composition in the southeast Atlantic,the composition of cat-ches,the contribution of major catches and the contribution of catches in coastal and non-coastal coun-tries and regions each decade.This results showed that the total catch of the southeast Atlantic increa-ses first and then decreases,and the total catch is low,accounting for less than 3％of the world total marine catch;Merluccius capensis,Engraulis capensis,Trachurus capensis and Sardinops sagax are the dominant species in the southeast Atlantic;catches of South Africa is the coastal state highest;cat-ches from non-coastal countries and regions such as Russia(Soviet Union),Japan,Spain,Poland,U-kraine,Bulgaria and Taiwan Province of People's Republic of China contribute significantly to the to-tal.The fishery resources in the southeast Atlantic have potential for exploitation,but the catch varies greatly among countries and regions;the main catch in coastal countries and regions such as South Af-rica is of low economic value while the developed countries such as European Union and Japan capture most of the high economic value fish like tuna.We suggest that the assessment of fishery resources in the southeast Atlantic should be strengthened,and a scientific and reasonable management and develop-ment system should be established among both coastal and non-coastal countries and regions so as to improve the fishing capacity and level and promote the sustainable development of fishery resources in southeast Atlantic.
