Creator:: Cadren, Muriel, Béne, Christophe, and Lantz, Frédéric
Abstract:: The arrival in the 1980s of cultured shrimp has induced large changes on the World shrimp market. In this new environment, the French Guyana fishery production now competes strongly with some of these farm-produced shrimp. Consequently, this fishery has experienced serious export problems during the last decade. This paper is...

Creator:: Akpalu, Wisdom
Abstract:: Studies on compliance with fishing regulations have looked at fishery crimes for which the offender faces a one-period decision problem of maximizing an expected utility. Moreover, the returns to the crimes are uncertain because the offender may lose them if caught. This paper extends these models by considering a fishery...

Abstract:: The objective of the paper is to briefly present a comparative analysis of trends in the characteristics of selected European fleets, observed over the last fifteen years, as an introduction to three empirical studies of the behavioural determinants of these trends. The analysis presented aims at (i) describing changes observed...

Creator:: Laloë, Francis
Abstract:: Fisheries models are generally built to assess the dynamics of a resource with a given fishing mortality which level can be decided by some “decision maker” and/or which can be an observed process, e.g. times series proportional to some observed values of fishing effort. In these cases, the resource dynamics...

Creator:: Wiyono, Eko Sri, Yamada, Sakurtaro, Tanaka, Eiji, and Kitakado, Toshihide
Abstract:: Considering the operational needs on fisheries management, this research was aimed for understanding the adjustment processes of small-scaled fishing gear dynamic by measuring and analysing the seasonal fishing gear dynamic including seasonal fishing pattern and fishing gear interaction. To understand the fishermen's adaptation of their fishing effort from any changes...

Creator:: Idels, Lev V. and Ou, Beiyan
Abstract:: We study the combined effects of periodically varying carrying capacity and survival rates on the fish population in the ocean (sea). We introduce a new delay differential equation model with a control parameter which describes how fish are harvested. We consider a predation function as the function of the delayed...

Abstract:: We develop a methodological approach using splines to analyze the deterministic population dynamics of fish stocks at low stock levels. Considering the aggregate Northern cod stock by way of illustration, we reject the hypothesis of strong compensation estimated by the conventional regression methods used by classic bioeconomic models.

Creator:: Mome, Masud Ara and Arnason, Ragnar
Abstract:: The hilsa shad (Tenualosa ilisha) fishery is by far the largest single species fishery in Bangladesh. In this paper, a simple bio-economic year-class based model is developed to describe the fishery and examine its properties. With the help of this model, the optimum sustainable yield of the fishery is calculated...

Abstract:: Exports of fish products are important to diversify sources of income and achieve higher standards of living to fisher folk. This paper attempts to trace the strategic situation of export oriented seafood industry in Sri Lanka, focusing on how the international market dynamics have influenced the emergence and development of...

Abstract:: In this paper an extended version of the well-known Faustmann model is developed for solving the rotation problem in fish farming. Two particularly important aspects of the problem are emphasized: namely first, the possibilities for cycles in relative price relationships and second, the problem with limitations in release time for...
