We introduce a modified version of the standard Gordon-Schaefer fishery model. Standard theoretical models usually treat fishing effort as an aggregate measure encompassing all different types of inputs. Consequently, these models do not enable us to examine the problem of fleet redundancy and capital stuffing separately, i.e. two ways in...
This paper reviews New Zealand‚ orange roughly fishery management and applies a bioeconomic model to explain the seamount depletion externality by bottom trawling. The model shows that despite an upper limit on annual harvest, the potential gains in economic rent from trawling on pristine habitat, where catch rates are high,...
The study was carried out in Anyigba, North central
Nigeria to analyze the distribution, marketing and
consumption
of sea food. It specifically sought to describe the
socio-economic characters of the fish marketers and consumers,
identify the distribution channel of fish, the species of fish sold and consumed‚ and preferences in...
With the development of the ecosystem approach to f
isheries (EAF), fisheries management is
increasingly required to deal with multiple, often
conflicting objectives. In this context, the
stochastic co-viability approach has been proposed
as a useful modeling framework as it allows
for the combined representation of complex fisherie
s dynamics,...
The Indonesian Coral Reef Rehabilitation and Management Program (COREMAP) is a 3 Phase, 18 year (1998 - 2016), USD 250 million national program aimed at protecting, rehabilitating and better managing Indonesia's coral reefs and their associated ecosystems and improving the livelihoods and incomes in target coastal communities where currently 60%...
A local fisheries management model employing short-term fisheries closures for rapidly growing species is proliferating across coastal east Africa and Indian Ocean islands. Aiming to improve management and boost incomes, NGOs, international finance institutions, and government agencies are promoting the technique in artisanal fishing communities. In southwest Madagascar alone, over...
In most decision making involving natural resources, the achievements of the policy (e.g., better ecosystem) are rather difficult to measure in monetary units. To overcome this problem the paper develops a modified Cost-Effectiveness Analysis (CEA) to include these intangible benefits in intertemporal natural resource problems. The proposed CEA framework is...
Employing an experimental approach, we examine whet
her the uncertainty on the fish/outputs price affects the
choice of vessel sizes of fishers under an ITQ scheme. Our experiment consists of two parts. In the first part,
subjects answer ten questions. The purpose is to extract the risk preference of each...
Salmon is an anadromous species that during its feeding and spawning migrations is sought after catch for commercial and recreational fisheries. The management of salmon fisheries is complicated by the combination of mixed and single stock fisheries. Thus, the country of origin has sovereign control over harvest of a salmon...
There is growing realization of the potential for games and experiments as powerful tools for education, outreach and research in many fields of science. Particularly in fisheries management we face a growing demand for stakeholder involvement, which requires new ways in reaching informed decision making. Games and experiments can be...
