This study aimed to examine the factors and influence of group dynamics independence fishing members in catch fisheries agribusiness activities. research was carried out using a survey method Rukun Nelayan Blimbing Paciran District, Lamongan Regency, East Java Province, Indonesia from February March 2019. The result showed fishermen high, but did not catching agribusiness. that were structuring...

加入変動を考慮した資源動態シミュレーションにおいて，バイアス補正項を考慮した対数正規分布が使われることが多い。しかし，加入尾数の変動が過程誤差であれば，バイアス補正により本来の加入尾数の変動と同じ分布は再現できない。一方，観測誤差による見かけ上の変動であれば変動させる必要がない。最大持続生産量（MSY）の推定において，バイアス補正は行わず実際の変動のみでシミュレーションを実施し，バイアス補正ありの結果と比較した。バイアス補正を行う現在の推定方法では，MSY等を過小または過大評価する可能性がある。

The paternally inherited Y chromosome has been widely used in population genetic studies to understand relationships among human populations. Our interpretation of Y chromosomal evidence about population history and genetics has rested on the assumption that all the Y chromosomal markers in the male-specific region (MSY) are selectively neutral. However, the very low diversity of Y chromosome h...

We, the Haíłzaqv, Kitasoo Xai'xais, Nuxalk and Wuikinuxv First Nations, are traditional stewards of our territories in Central Coast British Columbia, Canada. Our laws obligate us to manage protect for current future generations. Spatial management is inherent cultures through Hereditary Chief governance system, which specific people within a lineage inherit rights responsibilities stewarding a...

 United Nations Convention on the Law of the Sea (UN, 1982 (known as UNCLOS)), which includes a call for a maximum sustainable yield (MSY) approach to managing fisheries;  United Nations Conference on Environment and Development (UN, 1992a (known as UNCED)), including Chapter 17 of Agenda 21 which highlights a precautionary approach;  United Nations Straddling Fish Stocks Agreement of 1995 (...

Over the last decades, views on fisheries management have oscillated between alarm and trust in management progress. The predominant policy for remedying the world fishing crisis aims at maximum sustainable yield (MSY) by adjusting gear selectivity and fishing effort. Here we report a case study on how striving for higher yields from the Eastern Baltic cod stock by increasing selectivity has be...

A critical aspect in the design of a marine reserve (MR) network is its spatial configuration (i.e., the number, size, and spacing of the individual reserves), particularly how these features influence the effect on fisheries. Here, we derived a sizebased, spatially explicit, stochastic demographic model to explore how different spatial configurations of MR networks can affect abundance and com...

The various kinds of damages currently caused by wildlife throughout Japan can be attributed to the fact that the policies for management and utilization have lacked both a long-term perspective and an examination from the biological and economic points of view┻ This paper┼ therefore┼ addresses the issue of the management of the Yeso deer in Hokkaido and reexamines it┻ The paper presents three ...
