Abstract:: The natural estrogen 17β-estradiol (E2) is responsible for the endocrine disruption and also has potential effect on the reproduction of vertebrate. However, its effect on invertebrate reproduction has scarcely been studied. The present study was conducted to determine the effect of E2 on survival, egg production and egg hatch of...

Abstract:: Many of the world’s most valuable fisheries involve highly migratory stocks that cross national jurisdictions. These same fisheries face severe threats from direct overfishing or excessive bycatch. Traditional input and/or output controls generally have been costly and ineffective. Incentive-based programs that provide tradable shares in an annual total allowable catch...

Abstract:: In this paper, a bio-economic simulation model for the sea scallop fishery is established and its application in analyzing the area rotation management policy is demonstrated. Section 2 describes model specification and estimation and presents the empirical model. Section 3 evaluates two policy options using the model and the last...

Abstract:: The coastal fishery in French Guyana is a challenging case study for the implementation of the ecosystem based fishery management. Although the current situation of this small scale fishery could be considered as satisfactory, the viability of the fishery can be questioned. Indeed according to demographic scenarios, the growth of...

Abstract:: This paper presents a new bio-economic simulation model for the Italian fisheries developed as a part of a project financed by The General Directorate for Fisheries and Aquaculture (under the Italian Ministry of Forestry and Agriculture Policies). The main objective of the model is to measure the effects of different...

Abstract:: The objective of the paper is to analyse and to simulate fishers dis-investment behaviour especially in the context of the French buyback policy. A case study, the limited entry scallop fishery of the Saint-Brieuc bay is used to consider the problem of excess capacity and to review the impact of...

Abstract:: This study is aimed at evaluating the effectiveness of buyback program implemented last during a 10-year period using a bioeconomic model. Aggregate fisheries stocks are assessed by the surplus-production model and standardized aggregate harvest function is used in the bioeconomic model. The simulation result indicate that the fish stocks are...

Abstract:: The West Coast Rock Lobster fishery is Australia's most valuable commercial fishery. Around 550 vessels harvest 10,500 tonnes of lobster per annum. The industry has an enviable track record of biological management which has been based on a variety of input controls. In recent years this has necessitated three significant...

Abstract:: A bioeconomic model allowing different degrees of harvesting closures for two sub-stocks consisting of mature and immature fish is presented. Hence the model opens for partial closures of fisheries on both sub-stocks. Migration between the two sub-stocks is defined as recruitment of the young to the mature sub-stock, and egg...

Abstract:: Scallop fisheries are often characterized by variable abundance and periodic mass mortality occurrences. Area rotation is a respected management tool for sedentary species. A bioeconomic simulation model that incorporates the spatial and temporal distribution of scallop beds and fishing effort is presented. The model is user-friendly and was designed for...
