海洋保护区的渔业管理之模拟分析-论文范文

【中文摘要】:由于全球渔产资源面临枯竭危机,过去许多文献将海洋区域分为两区域,一区为可捕鱼区、一区为海洋保护区(Marine Protected Areas ,以下简称MPAs

),一旦划分MPAs短期经济收入下会受到负面冲击,但是藉由MPAs复育提高鱼群存量,再透过鱼群在海洋移动的效用,长期下来,不但可以得到渔业稳定最大利润,还能使得鱼群存量保持稳定,且面对不确定性时,也能保持其一定的效用。

本研究结合建置海洋保护区渔业资源保护的概念,将海洋区域划分为两区,当一区开放为可捕鱼区,另一区即列入保护区以给予渔业资源回复再生空间,不同于以往文献,只单单倚靠鱼群移动的效用及透过单一区域复育能力,带来稳定的鱼群存量,而是将两区设置为可以转换的状态下,捕捞达到一定时间、一定捕捞的水準后,交换两区的设置状态,即将原可捕鱼区转换成海洋保护区,反之,原为海洋保护区开放为可捕鱼区。本研究将探讨两区状态转换的MPAs的海洋资源管理的方法,在渔业经济捕捞利润及鱼群资源再生复育的效益。探讨两区域的最适转换设置时间,透过适当的人为管理海洋资源区域,除达到保有生物永续发展的多样性,海洋资源生生不息之外,并达成渔业长期稳定经济利益。

根据模拟分析,得知了本研究藉由MPAs、可捕鱼区,两区交替转换的状态下,除了可以得到渔业经济带来的长期收入,资源数量及多样性、生态环境平衡得以维持而永续发展,也能使得两区域藉由交替转至状态都能获得生态环境回复的空间以维持稳定的生态环境,并在特定一些情况下可以对抗环境受到负面不确定性冲击。

关键词︰海洋保护区、渔群存量、触发价值、负面不确定性、捕获量
【英文摘要】:Due to global demand aquatic resources face the risk of depletion. In past articles, researchers divided the sea into two areas: One of areas for fishing; the other as a marine protected area which protects the fishery resources. With the MPAs established, short-term economic profit will be negatively impacted. However, MPAs bolster fisheries renewability, and thus could increase the fish stock via movement of fishes in the ocean. With by time, the sustainable harvest of MPAs could not only obtain the maximize profit and keep the marine stocks stable, but also have the utility effect to face uncertain situations.
This study is the combination of different design concepts which protect fishery resources through MPAs. One area is open tfor the fishing, the other is the marine protected areas intended for regeneration of fishery resources. This concept is different from the past literatures, which only keep the marine stock stable and rely on fish movement and inhenent renewable capacity in a single area. The intent of this paper is to establish two areas that atternate roles for when the catch rates reaches a certain time or level. The original fishing area is converted

into a marine protected area, while the original MPA is opened for fishing. This study will explore a managing method which exchanges the state of these two areas, for the fishery’s economic profit and the benefit of restoring the fishery resources. The optimal time for transitioning two areas, is controlled by human efforts. In addition achieving the sustainable development of biological diversity and making the development sustainable, this strategy ensures stability and long-term fishery economic benefit.
According to the simulation analysis, this study shows that exchanging MPAs and fishing areas, in addition to economic advantage, has the long-term benefit of ensuring the quantity of resources, biodiversity and the ecological balance of the areas. Alternating conversion of these states of the two areas also provides ecological environment restoration spaces which maintain a stable ecosystem. Even with negative external stimuli, the ecosystem can still remain functional.
