问题 In recent years shrimp harvests of commercial fishermen in the South Atlantic have declined dramatically in total weight. The decline is due primarily to competition from a growing number of recreational fishermen, who are able to net young shrimp in the estuaries where they mature. Which of the following regulatory actions would be most likely to help increase the shrimp harvests of commercial fishermen?

选项 A、Requiring commercial fishermen to fish in estuaries.
B、Limiting the total number of excursions per season for commercial fishermen.
C、Requiring recreational fishermen to use large-mesh nets in their fishing.
D、Putting an upper limit on the size of the shrimp recreational fishermen are allowed to catch.
E、Allowing recreational fishermen to move out of estuaries into the South Atlantic.

答案 C

解析 本题问题目的是让我们去寻求选项以增加commercial fishermen的河虾捕获量,因此,方法只能从消除commercial fishermen的河虾捕获量下降的原因入手,而这个原因是由于recreational fishermen在河虾成熟的海湾处捕捉到young shrimp。(C)指出要求recreational fishermen使用大网眼的网,这样就可以使小河虾仍然在河中生长繁殖,从而消灭了这个原因,实现了问题目的,所以(C)正确;(A)、(B)、(E)可很容易排除;(D)易误选,但(D)中“upper”的意思与我们的问题目的刚好相反,若把“upper”改为“lower”就对了。
