Abstract

We evaluated the commercial and recreational fishery landings over the past 22 years, first at the national level, then for populations of concern (those that are overfished or experiencing overfishing), and finally by region. Recreational landings in 2002 account for 4% of total marine fish landed in the United States. With large industrial fisheries excluded (e.g., menhaden and pollock), the recreational component rises to 10%. Among populations of concern, recreational landings in 2002 account for 23% of the total nationwide, rising to 38% in the South Atlantic and 64% in the Gulf of Mexico. Moreover, it affects many of the most-valued overfished species-including red drum, bocaccio, and red snapper-all of which are taken primarily in the recreational fishery.

摘要

我们评估了过去22年的商业和休闲渔业上岸量,首先是在国家层面,然后是针对受关注的种群(那些被过度捕捞或正在经历过度捕捞的种群),最后按地区进行评估。2002年休闲渔业上岸量占美国海洋鱼类上岸总量的4%。如果排除大型工业渔业(如鲱鱼和狭鳕鱼),休闲渔业部分则升至10%。在受关注的种群中,2002年休闲渔业上岸量占全国总量的23%,在南大西洋升至38%,在墨西哥湾升至64%。此外,它还影响到许多最有价值的被过度捕捞的物种,包括红鼓鱼、博氏岩鱼和红鲷鱼,所有这些主要都是在休闲渔业中被捕捞的。
