Worldwide, the scientific community and international organisations have
gradually agreed on the need for an ecosystem-based approach to fishery
management. However, the practical implementation of such an approach
faces huge problems, especially in developing countries where current
fishery management systems are generally weak.
One way to improve a fishery management...
The international council for the exploration of the seas (ICES) publish
annual reports on fish stock assessments. Based on the stock assessment
data for the North-East Arctic cod we estimate the effective fishing
mortality, establishing coefficients for the catchability-at-age and the
annual fishing effort. The fishing effort estimates are then...
This paper analyzes the effects of spatial closures on the multi-species
groundfish trawl fishery in northern and central California. The analysis
differentiates between changes in total effort and in the spatial distribution
of effort before and after implementation of the closures. We use logbook
data on the location and duration...
There is an increasing demand for marine space from many different economic sectors in the German coastal and exclusive economic zone: sand and gravel removal, wind farms, fisheries, shipping or oil and gas exploration. Additionally, the Natura 2000 directive requires the declaration of areas for nature con-servation. Opposite to other...
In the administration of its quota management system (QMS), New Zealand sets a “deemed value” fee that must be paid for any landings in excess of annual catch entitlements (ACE.) The deemed value system is an example of a price-capped cap-and-trade system (Roberts and Spence 1976). This paper argues that...
Recreational fisheries regulations at the state level along the US Atlantic coast are constantly changing to ensure the sustainability of marine fish populations. It is hypothesized that effective management of recreational fishing effort should have a positive impact on fish stocks. Using recreational catch per unit effort (CPUE) as a...
Recreational fishermen quickly adjust fishing effort directed at a specific
site to variations in fishing quality. Holding all other quality parameters
constant, the functional relationship between fish abundance and the
resulting recreational fishing effort is denoted an effort response function.
This paper proposes a Cobb-Douglas utility function for the benefits...
Prior to the introduction of the modern management regime, the concept of capacity constituted no other reference than the technical capacity of a given fishing vessel. However, after closing the commons and the introduction of a an heavily institutionalized management regime, the fisheries sector have been transfomed to complex web...
The spatial, multi-species nature of coral reef fisheries makes them notoriously difficult to manage. We
have developed a simulation modeling approach to examine the effect of management options on the
recreationally important tourist destination of Ningaloo Reef in Western Australia where a recreational
fishery targets Spangled Emperor (Lethrinus nebulosus). The...
The case for assigning private property rights in fisheries has been
thoroughly studied but has lead to a new debate over whether rights should
be allocated to groups or individuals. The New England groundfish fishery
provides a rich context in which to study this question. Beginning in 2004,
several dozen...
