In this study, we tried to develop a theoretical framework based on the Schaefer model and establish bioeconometric models to estimate the index of fishery resources using cross-country macro data. The characteristics of our model are that we consider the effect of natural fluctuations of fishery resources over time (in...
The efficiency analysis literature has long acknowledged the difference between program/policy effects and relative efficiency effects. The use of incentive compatible policy has been an important research agenda for fisheries economists, and Canada uses an array of policies and regulatory tools to fulfill the objectives of their Fisheries Act. One...
The structure of wholesale and retail marketing catfish (Clarias gariepinus) were analysed in order to assess the degree of competition and understand the organization of the farm raised catfish (Clarias gariepinus) market in southwestern Nigeria, a major aquaculture fish producing area in Nigeria. The market was evaluated by considering the...
By 1992, the Canadian cod populations collapsed and
a moratorium on fishing was declared, which
remains in place until today. Ecologists suspect that the marine ecosystem at the Canadian east coast
has
shifted towards a new regime, where cod stocks remain at a low level while other species biomass levels,...
Over 90% of global aquaculture production comes fro
m the Asia Pacific region. International trade in live
aquatic animals and the intensification of aquaculture practices over the past several years have led
to
emergence and spread of several aquatic animal diseases in the region. At the same time, while the...
Fish stocks are facing increasing threat of extinct
ion partly due to the use of illegal fishing methods. In developing
coastal countries where fishing activities are the
mainstay of the population along the coast, livelihoods are being
directly threatened. Although a number of studies unearthing factors determining supply of violation...
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,...
Export economy has been interrupted in shrimp/prawn, the second largest earning source of Bangladesh due to detection of Nitrofuran in export ed prawns to the EU countries. Around 100 consignments of frozen prawn (Macrobrachium rosenbergii) were rejected at the EU borders between 2005 and 2009. Bangladesh exported shrimp and fish...
The “Lake Chad” is one of the world, largest and most historical Lake located in the Sahel region of
Africa (lat. 12:30 N to 14:30 N and long. 13:00E to
15:30 E ) which is one of the most vulnerable regions
to climate change bordering North-Eastern Nigeria,
North-Western Cameroon, South-Eastern...
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...
