キノコの件

急にTwitterでキノコのイメージを聞いたのは、以下の英文中に使われているmushroomという単語が気になったからでした。

^*Shrimp aquaculture or farming first became profitable about 20 years ago and has since mushroomed into a major industry in developing countries. While total catches of wild shrimp have remained relatively stable at about 2 million ^*metric tons per year over the past two decades, farm-raised production has exploded from around 80,000 metric tons in 1980 to more than 1 million metric tons in 2000. These shrimp are raised in shallow ponds ranging in size from a few hundred square meters to many hectares, generally constructed on or near the coastline of a tropical country.

^*Shrimp aquaculture：エビの養殖   ^*metric tons：(メートル法で)トン
