The Leslie¡¦s method was employed for the estimation of stock size and catchability coefficient of Sakura shrimp on the southwestern coast of Taiwan from Nov 2002 to May 2004. After analyzing the stock size and catchability coefficient and then applying those estimated value for the optimal conduction of open-access and bioeconomic optimum, the evaluation of the variation under both conductions were available and simulations run by the catch data also can be obtained and useful in comparing with the real situation. By assuming all bioeconomic parameters varied within a reasonable range, we did the comparative static analysis and expected to shed the light on the impact those parameters brought to the stock size.

A partir de acordos entre empresas de emigração japonesas, o Instituto de Reforma agrária (IRASC) e o consulado de Porto Alegre (RS), a colonização de terras foi realizada por imigrantes japoneses, vindos de outros Estados brasileiros e diretamente do Japão. Nos meados da década de 1980, outro fluxo migratório começa a se configurar no Núcleo: japoneses e seus descendentes nascidos no Brasil decidiram partir em direção ao Japão, em busca de empregos nos setores industriais, inserindo-se no mercado de trabalho japonês como mão-de-obra não qualificada. Neste momento, em meio ao "Movimento Dekassegui", aqueles que permaneceram no Núcleo Celso Ramos iniciaram a construção de espaços tais como o Parque Sakura e o Sakura Matsuri. Este local e festa, respectivamente, tornam-se espaços polissêmicos, onde tradição e turismo mantêm uma relação de tensão e proximidade, que perpassam pela percepção de conflitos entre gerações. Neste sentido, esta dissertação tem por objetivos a compreensão das polissemias produzidas no processo de construção do Parque Sakura e do Sakura Matsuri, que não sem conflitos, se encontram entre memórias e narrativas que evocam um passado antes latente, construindo sentidos, proximidades, significados e identificações no presente

Tong-Kong sakura shrimp is one of important fisheries in southwest coast. Tong-Kong sakura shrimp, blue fin tuna and mullet roe are called Three Treasures of Tong-Kong . It brings significant economic benefits for local residents. This research is based on Gordon-Schaefer Model theory that combines with fishery catch statistics and operational cost data. Also, we use these data to discuss open-access fishing ground and dynamically optimal fishing ground of balance status under equilibrium level. Next step is to do stimulation analysis that based on annual fishery catch statistics of sakura shrimp. After stimulation, we can make comparisons of equilibrium values of these two fishing grounds. From analysing fishery catch statistics and fishing resource we may know that it can shows that the management of sakura shrimp tends to dynamically optimal fishing ground, and also can state that the management mechanism of sakura shrimp is an ideal of sustainable management. Then, through the example, we can understand how each variation influences fishing resources and fishing effort of these two fishing grounds. Finally, we simulate fishing resources model of two fishing grounds to show the result. If we don¡¦t manage fishery of sakura shrimp well and keep uncontrolled fishing, not only the fishing ground will become an open-access fishery, but also fishing resources will become extinct. However, once we can manage fishing ground efficiently, it will become a dynamically optimal fishing ground and the fishery of sakura shrimp will develop sustainably.
