As part of the Namibian government initiative on sustainable resources development, the Ministry of Fisheries and Marine Resources strongly urges right holders to continuously engage in value addition and market diversification of their products in an effort to realise maximum returns on their products. The importance of being in line...
Globalisation in the retail sector is transforming food value chains by driving consolidation in the industry and extending supply chains across the globe. Globalisation enables retailers to benefit from economies of scale and cheaper production in foreign locations. However, food markets themselves are increasingly responding to local consumer preferences. In...
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...
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...
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...
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...
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...
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...
A scientific knowledge gap exists with regard to how benthic habitat is affected by destructive fishing methods, such as bottom trawling, and how this impacts upon the productivity of commercial fish stocks. This
article addresses analytically the effects of destructive fishing practices of a single gear fishery on a non-renewable...
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...
