A Bioeconomic Analysis of the Texas Shrimp Fishery and Its Optimal Management
研究德克萨斯虾类渔业在不同时期和区域的过度捕捞问题，通过多期数学模型确定最优捕捞模式，并与实际努力量比较，发现春夏季节存在大量过剩努力，最优捕捞季节晚于实际，减少努力对生产者和消费者均有益。
Abstract Overfishing in the Texas shrimp fishing industry by time period and fishing area is investigated. An optimal harvesting pattern is determined using a multiperiod mathematical programming model where prices, fishing effort, catch, and resource dynamics are treated endogenously. These results are then compared with actual effort. The comparison indicates substantial excess effort in spring and early summer, especially in the bays and shallow offshore areas. The peak fishing season also occurs later in the fall in optimal harvest pattern than in practice. The results indicate both producers and consumers gain from reduced fishing effort because of improved size composition of the harvest.
