Management System Could Keep Tuna on Table
It’s fairly well known that fish stocks are collapsing around the world. But there’s a management method that appears to offer long-term environmental and economic success, according to a study published September 19th in the journal Science. It’s called catch shares, and it works like this. Each fishermen—or fishing cooperative— receives a percentage of the total catch. Scientists determine the catch for the year. And the fisherman is guaranteed his fixed percentage, year after year. He thus has a direct financial stake in the future of the fishery.
The researchers evaluated data for more than 11,000 fisheries. Less than 1 percent had implemented catch shares. But in addition to higher incomes for fishermen, those systems had half as many collapses as other fisheries. And researchers think that number will improve further, because the catch shares may have been only recently implemented. Catch shares have been around for awhile, but they’ve been slow to catch on. One reason has been a lack of data on whether they do any good in the long run. With this study, maybe that will change. That’s a good thing for the fishermen, the consumer and especially the fish.
管理系統(tǒng)可能讓我們以后還有魚吃
眾所周知目前世界上的魚的庫存正在瀕臨崩潰。但是根據9月19日《科學》雜志 （Science）的一項研究，有一種管理方法似乎能提供對于環(huán)境和經濟都適用的長期解決方案。它被稱為“捕撈份額”，具體運作如下：每個漁民——或者漁業(yè)聯(lián)合公司——獲得總體捕撈的一個百分比份額?？茖W家們決定每年捕撈的數(shù)量，每年漁民所得到的份額百分比是固定的。這樣一來，漁民的經濟利益就和漁業(yè)的未來直接掛上了鉤。
研究者們對11000多個漁場的數(shù)據進行了評估，只有不到1%的漁場執(zhí)行這樣的“捕撈份額”。不過，執(zhí)行管理系統(tǒng)的漁場除了漁民的收入更高外，這樣的漁場出現(xiàn)“庫存耗盡”的情況只有其它漁場的一半。研究者們認為這個數(shù)字還能進一步改善，因為捕撈份額可能僅僅剛剛開始執(zhí)行。捕撈份額的出現(xiàn)還不久，但是要讓它變得流行還很慢。一個原因就是缺乏這樣的數(shù)據：它能告訴我們從長遠看這樣的管理系統(tǒng)是否能帶來好處。有了這個研究，或許捕撈份額會更快流行起來。這對漁民、消費者尤其是對魚來說都是個好事。
