大西洋约占全世界海洋面积的1/4。根据1975年莫伊谢耶夫的分析,大西洋的潜在平均鱼产量为350公斤/平方公里。这就大大地超过世界的(230公斤)、太平洋的(245公斤)和印度洋的(80公斤)平均的类似指标。到二十世纪五十年代中期,大西洋给人类提供了世界海洋生物每年渔获量的50％以上。在1960—1974年间,由37％上升到45％,而1975—1982年间,在世界渔获量中大西洋部分却出现了某些下降的趋势,由41.9％下降到36％。战前时期(1938年),大西洋捕获了930 The Atlantic accounts for about a quarter of the world’s marine area. According to Moisheyev’s analysis in 1975, the potential average fish production in the Atlantic Ocean was 350 kgf / km2. This greatly exceeds the average of similar indicators in the world (230 kg), the Pacific (245 kg) and the Indian Ocean (80 kg). By the mid-1950s, the Atlantic provided humankind with more than 50% of the annual catch of the world’s marine life. Between 37% and 45% between 1960 and 1974, some declines in the world’s catch in the Atlantic occurred between 1975 and 1982, from 41.9% to 36%. Pre-war period (1938), the Atlantic caught 930
