Industrial longline fishing can be understood as a case study of the cultural, economic, environmental and social impacts of unsustainable fishing technology. While much attention has been attributed to the impact of industrial longlines on the marine ecosystem, little is known about the impact of longline fishing on local food security, employment, cultural belief systems and traditions, reven...

The design of existing fishing schemes is carried out according to prototypes, which causes a low level safety in operations, and, as result, leads an increase accidents among crew members. As practice shows, such cases can be avoided already at the stage designing field scheme. In order find how changes direction increasing will affect their efficiency use, paper proposes assess risks scheme, ...

Climate change is predicted to have a range of direct and indirect impacts on marine and freshwater capture fisheries, with implications for fisheries-dependent economies, coastal communities and fisherfolk. This technical paper reviews these predicted impacts, and introduces and applies the concepts of vulnerability, adaptation and adaptive capacity. Capture fisheries are largely driven by fos...

A key challenge in contemporary ecology and conservation is the accurate tracking of the spatial distribution of various human impacts, such as fishing. While coastal fisheries in national waters are closely monitored in some countries, existing maps of fishing effort elsewhere are fraught with uncertainty, especially in remote areas and the High Seas. Better understanding of the behavior of th...

The considered model will be formulated as related to ”the fishing problem” even if the other applications of it are much more obvious. The angler goes fishing. He uses various techniques and he has at most two fishing rods. He buys a fishing ticket for a fixed time. The fishes are caught with the use of different methods according to the renewal processes. The fishes’ value and the inter arriv...

The ocean surgeonfish Acanthurus bahianus, an abundant small herbivore on reefs throughout the tropical west and central Atlantic, is a significant component of Caribbean trapfishery catches. To assess effects of fishing on this species we compared its longevity, survivorship, size and abundance at localities throughout its range that have differing intensities and targets of fishing. Temperatu...

Fish is generally regarded as a primary source of protein for many poor African fishing communities. The present study compared the relative importance of fish as a high-quality dietary protein source with meat in fishing communities in two states in Nigeria. Fifty fishing households in which active fishing was the primary activity and fifty non-fishing households (agriculture being stated as p...

Historically, it has been difficult to balance conservation goals and yield objectives when managing multispecies fisheries that include stocks with various vulnerabilities to fishing. As managers try to maximize yield in mixed-stock fisheries, exploitation rates can lead to less productive stocks becoming overfished. In the late 1990s, population declines of several U.S. West Coast groundfish ...

fishing as one of the most important agricultural sectors has an important role in providing the protein for people. pareh cooperatives despite of having a long history, are faced with problems such as loss of fishing catch compare with previous years, the high cost of purchasing tools and equipments to catch and transportation and location of fishing become unfavorable due to natural and human...

The Falkland Islands are an important breeding site for three species of penguin, gentoo (Pygoscelis papua), southern rockhopper (Eudyptes c. chrysocome) and Magellanic penguin (Spheniscus magellanicus). The total penguin population for the Falkland Islands has declined by 84 % during the 1980s and 1990s. These declines did not occur in coastal South America, so potential causes of decline in t...
