A value-based individual transferable quota scheme - a preliminary examination of its suitability as a fisheries management technique

Creator:: Willmann, Rolf
Abstract:: An ITQ scheme has been shown to create a quota induced incentive for discarding of fish in excess of what is socially optimal. This finding is corroborated by empirical evidence in several ITQ managed fisheries. The incentive for discarding, over and above those expected in an unmanaged or input controlled...

Toward a New Paradigm of the Fisheries Management

Creator:: Kawasaki, Tsuyoshi
Abstract:: Fisheries management has been carried out on the assumption that a fish population is in equilibrium with the fishing effort under the average environmental conditions and hence there must be a maximum sustainable yield (MSY). However, since the simultaneous rise and fall of the interdecadal and global scale of sardine...

Can Stochasticity Cause Overcapacity in a Pure Open Access Fishery?

Creator:: Rust, Steven, Yamazaki, Satoshi, and Jennings, Sarah
Abstract:: Overcapacity remains a major issue in world fisheries. The specific conditions that give rise to overcapacity in the pure open access fishery remain unclear, however the non‑malleability of capital is widely regarded as a necessary condition for the accumulation of excess harvesting capacity. In the process of fisheries collapse known...

A Model of Fishing Conflicts in Foreign Fisheries

Creator:: Wachsman, Yoav

We develop a game-theoretical model in which a fishery owner maximizes the revenue that it collects from firms that operate in its EEZ by charging them a fishing fee. We find that...

Estimating a Generalized Gordon-Schaefer Model with Heterogeneous Fishing Data

A Cobb-Douglas production function is consistently estimated in the first stage by means of the ‘within period estimator’. A stock index is constructed and used to estimate the logistic growth model...

Abstract:: We investigate the effects of incorporating a fixed input on equilibrium profits and biomass.

We use this model to get predictions for...
