Creator:: Mingkid, Winda Mercedes, Wiyono, Eko Sri, Pinontoan, Benny, Watanabe, Seiichi, and Yokota, Masashi
Abstract:: The aim of management is to ensure the sustainability of the resource while maximizing economic returns to the community. This paper explained methods of detecting fisheries stock in Indonesia including survey, swept area, acoustic, statistical and tagging. In order to succeed in the future, integrated work between the decision maker...

The Economics of Overexploitation Revisited

Creator:: Grafton, R. Quentin, Kompas, Tom, and Hilborn, Ray
Abstract:: About 25% of the world's fisheries are depleted such that their current biomass is lower than the level that would maximize the sustained yield (MSY). Using methods not previously applied in the fisheries conservation context, we show in four disparate fisheries (including the long-lived and slow-growing orange roughy) that the...

The management of transboundary marine resources : recent developments and elements of analysis

Creator:: Thébaud, Olivier
Abstract:: Under the new Law of the Sea, the definition of exclusive zones was considered an important first step towards improved management of the world's fisheries. However, one of the limits to the effectiveness of extended Jurisdictions was the problem of transboundary fish stocks. This question recently appeared at the centre...

Karl Popper's Organon and the world's fisheries; fish stock assessment as a pseudoscience, an inductivism that can bear no fruit

Creator:: Corkett, Christopher
Abstract:: If a scientist can predict the weather (poorly) Why cannot he predict fish yields (yet more poorly)? – a clerihew by Chris Corkett. Recent long term historical studies of commercial fisheries have pointed to a well established pattern of overfishing. Under the principle of transference – what is true in...

Rents and Rents Drain in the Icelandic Cod Fishery

Creator:: Arnason, Ragnar
Abstract:: This paper estimates current resource rents being generated in the Icelandic cod fishery and compares them to the maximum sustainable attainable ones. For this purpose a simple aggregative model of the cod fishery is specified and empirically estimated. It is found that in spite of the cod stock being in...

Habitat-destructive fishing practices

Creator:: Mikkelsen, Eirik
Abstract:: A model for studying how destructive fishing practices may affect commercial fish stocks through their effect on habitat is presented. It may be used both for renewable habitat-types, like eelgrass (Zostra marina) or sponges, and also practically non-renewable habitats like corals. The model demonstrates the trade-offs between using destructive and...

Fisheries induced evolution. A review

Creator:: Reithe, Siv and Primicerio, Raul
Abstract:: Age and size at maturity are key life-history traits in a fish stock. At the individual level, age and size at maturity affect fecundity, growth and survival. At the population level these factors interact to affect the age and size distribution, the population dynamics and the productivity of the stock....

Practical challenges of fisheries co-management on large water bodies: Lessons from southern Lake Malawi

Creator:: Njaya, Friday
Abstract:: Efficient management of small-scale fisheries resources demands adequate human and financial resources. This mainly relates to research and enforcement activities. Despite the resource constraint, the state has assumed the role of managing the fisheries resources. The emerging global trend, however, recommends cost recovery systems for sustainable fisheries management to achieve...

Stock and (possibly) path dependent technologies

Creator:: Arnason, Ragnar and Willmann, Rolf
Abstract:: According to conventional economic wisdom the economically more efficient technology will always outcompete the less efficient. This hypothesis has usually been taken to hold for the exploitation of common pool renewable natural resources such as fish stocks. This paper claims that, while this is not necessarily false, it may be...

Capacity Measurement and Policy Simulation of Fishery Industry in Japan

Creator:: Managi, Shunsuke
Abstract:: The expansion of fishing capacity is one of the most pressing problems facing many fisheries around the world. Excess capacity arises when a high number of vessels enter the fishery, and these vessels are employed to exploit the available fish stocks beyond a target level of yield. The lack or...

The Lofoten Fishery Over a Hundred Years

Creator:: Hannesson, Rognvaldur, Salvanes, Kjell, and Squires, Dale
Abstract:: The Lofoten fishery exploits the spawning migration of the Northeast- Arctic cod and is one of the fisheries in the world with the longest history. Since 1860, data on participation and catches in the Lofoten fishery are available. For about a hundred years, labor productivity in this fishery, measured as...

Limits to the privatization of fishery resources

Creator:: Clark, Colin, Munro, Gordon, and Sumaila, U. Rashid
Abstract:: A debate is emerging over the extent to which privatization of fishery resources – private ownership and resource management without significant state oversight- is practical and socially desirable. What we term the “optimists” maintain that there are no effective limits to privatization and that the decades old fear that privatization...

An analysis of the fishmeal industry: From wild fisheries to international fishmeal and fish oil markets

Abstract:: Because of the stagnation of commercial landings, the development of aquaculture activities is expected to rise during the next decades to match the growing demand for fisheries goods. Overall, it is often expected that the aquaculture sector could reduce to a certain extent the pressure applied over wild stocks. However,...

Location Choice Behavior Modeling of Shrimp Fishermen in the Gulf of Mexico

Abstract:: The shrimp fishery accounts for more than one-half of the total revenues generated by commercial fishing activities in the U.S. Gulf of Mexico. Due to its historical open access nature the harvesting sector has historically been overcapitalized (from an economic perspective) resulting in a suboptimal generation of rents.

Abstract:: In southeast Portugal, some coastal fishing communities have experienced intensified competition for harvestable stocks, and this impacted with some severity on small-scale fishermen who are especially dependent on fishing for their livelihoods.

Ecological Benchmarking to Explore Alternative Fishing Schemes: The Danish Demersal Fishery in the North Sea

Abstract:: The cod stock in the North Sea is threatened by overexploitation. To recover this fishing stock, pressure needs to be reduced. This implies that catch compositions with small amounts of cod are preferred by public policy makers. The present analysis assesses the technological efficiency of fishing trips, considering landings of...
