Finding the optimal opening time of harvesting farmed fishery resources

Stochastic optimization model of aquacultured fish for sale and ecological education

A stochastic optimization model for management of aquacultured fish for sale and ecological education is established. Population dynamics of the fish is described with a system of stochastic differential equations assuming that they are stochastically harvested after an opening time: the variable to be optimized. A remarkable difference between the present and conventional models for the aquacu...

Comparative possession of Shiga toxin, intimin, enterohaemolysin and major extended spectrum beta lactamase (ESBL) genes in Escherichia coli isolated from backyard and farmed poultry

The present work was conducted to compare the occurrence of Escherichia coli possessing virulence and ESBL genes in backyard and farmed poultry. Three hundred and sixty samples from the poultry kept in backyard system and 120 samples from the farmed birds were collected from West Bengal, India. Among the E. coli isolates of backyard poultry (O2, O10, O25, O55, O60, O106, UT), none of them posse...

An Analysis of A Fishing Model with Nonlinear Harvesting Function

In this study, considering the importance of how to exploit renewable natural resources, we analyzea shing model with nonlinear harvesting function in which the players at the equilibrium pointdo a static game with complete information that, according to the calculations, will cause a wasteof energy for both players and so the selection of cooperative strategies along with the...

Optimal Harvesting Strategies for Farmed Fish and Shrimp in Hawaii , Year 2

Management of a Cooperative Fishery With Cyclic Environmental Shocks

Previous work has examined optimal fisheries management in idealized institutional contexts, as well as the effectiveness of real institutions in improving the efficiency of the fishery, but there remain further connections to be made between these literatures. Fishing cooperatives have been advocated as a community-based institution that can successfully manage resources where top-down managem...
