Mathematical modeling applied to renewable fishery management

A companion modeling approach applied to fishery management

Don Hoi Lord, a coastal wetland in the upper gulf of Thailand, is famous for the razor clam (Solen regularis), which is a source of food and income for local fishermen. However, the razor clam population is significantly decreasing so the aim of this study was to analyze the razor clam fishery and develop a management plan engaging the different stakeholders in collective discussions. A partici...

An Experimental Analysis of Optimal Renewable Resource Management: the Fishery‡

Abstract This paper investigates experimentally the extraction-decisions of a sole-owner of a fishery, the population dynamics of which behave according to the standard deterministic logistic growth model. Four treatments were implemented which differed in the level of information supplied to the experimental subjects. The theoretical solution was used to evaluate the behaviour of the subjects ...

Mathematical modeling applied to the left ventricle of heart

Background: How can mathematics help us to understand the mechanism of the cardiac motion? The best known approach is to take a mathematical model of the fibered structure, insert it into a more-or-less complex model of cardiac architecture, and then study the resulting fibers of activation that propagate through the myocardium. In our paper, we have attempted to create a novel software capable...

Qualitative mathematical models to support ecosystem-based management of Australia's Northern Prawn Fishery.

A major decline in the catch of the banana prawn [shrimp], Penaeus (Fenneropenaeus) merguiensis, occurred over a six-year period in the Weipa region of the northeastern Gulf of Carpentaria, Australia. Three main hypotheses have been developed to explain this decline: (1) prawn recruitment collapsed due to overfishing; (2) recruitment collapsed due to a change in the prawn's environment; and (3)...
