1. Technological entropy and its implications to fisheries governability

Author:

fisheries; sustainable fisheries,   etc   ; entropy; governance; society;     Show all 5 Subjects
Abstract:
... The interactive governance theory postulates that the governability of a fishery system depends on the governing capacity, and the overall quality of the system to be governed. The elements making the fisheries more or less governable correspond to the diversity, complexity, dynamics, and scale of the natural and social systems that are being governed and the governing system. To date, the extent ...

Abstract:
... Although fishing is regarded as a risky production process, limited attention has been given to the impact of input factor use on production risk. Production risk is particularly important for fisher behavior and fisheries management when input factors are restricted, since input restrictions can influence production risk in addition to output levels. This paper investigates production risk by est ...

Abstract:
... Changes in fish distribution are being observed across the globe. In Europe's Common Fisheries Policy, the share of the catch of each fish stock is split among management areas using a fixed allocation key known as ‘Relative Stability’: in each management area, member states get the same proportion of the total catch each year. That proportion is largely based on catches made by those member state ...

Abstract:
... This paper uses game theory to analyze commercial fishers’ willingness to practice conservation to recover a depleted fishery. We compare a game in which players choose their conservation effort simultaneously to a game in which there is a leader and a follower. We show that because the players ignore the effect of their conservation effort on the other player's expected benefits, their collective ...

Abstract:
... Understanding fisher beliefs and attitudes towards specific management strategies can help inform and improve fisheries management, and thus stock sustainability. Previous studies highlight a lack of fisher awareness regarding environmental issues influencing the systems they utilise and the negative impacts of specific strategies, such as stock enhancement. Our study used a two-phase approach to ...

Abstract:
... Corrupt enforcement of harvesting restrictions hampers the management of common-pool resources in many developing countries, contributing in particular to widespread illegal fishing and logging. In this paper, we examine a simple intervention that may mitigate the effects of such corruption if, as is often the case due to congestion, stock, or pecuniary externalities, harvesters’ effort levels are ...

Abstract:
... Based on 18-months of ethnographic fieldwork in South Africa’s Western Cape province, we suggest ways in which marine resource law enforcement activities can be evaluated at the level of individual fisheries compliance inspectors, to gain a more accurate understanding of the state of marine resource law enforcement. We show that these individual assessments can be scaled up to speak about specific ...

Efforts to spatially quantify the historical catch of global tuna fisheries have been restricted to the few taxa of major economic interest, creating a trunca ...

The role of aquatic resources to food security is both promising and constrained since the global seafood consumption is increasing while marine fisheries approach the limit of what it can produce. In Sweden, the seafood consumption per capita is higher than the European and world average but the current dietary advice is to increase consumption. Freshwater fisheries have in general been paid less ...

Stock enhancement activities provide an opportunity to examine density-dependent suppression of population biomass which is a fundamental issue for resource management and design of no-take-zones. We document ‘catch-and-wait’ fisheries enhancement where all but the largest lobsters are thrown back, recapturing them later after they have grown to a larger size. The residency, rate of return, and po ...

Abstract:
... Coral reef fisheries support the livelihoods of millions of people in tropical countries, despite large‐scale depletion of fish biomass. While human adaptability can help to explain the resistance of fisheries to biomass depletion, compensatory ecological mechanisms may also be involved. If this is the case, high productivity should coexist with low biomass under relatively high exploitation. Here ...
