Illegal and unreported fishing contributes to overexploitation of fish stocks and is a hindrance to the recovery of fish populations and ecosystems. This study is the first to undertake a world-wide analysis of illegal and unreported fishing. Reviewing the situation in 54 countries and on the high seas, we estimate that lower and upper estimates of the total value of current illegal and unrepor...

Illegal, Unreported, and Unregulated (IUU) Fishing is a challenge in fisheries management has the potential to threaten stability of maritime security, especially Indonesia. IUU typically associated with other crimes such as smuggling, human trafficking, drug abuse, rights abuses. also adverse impacts economically, ecologically, socially.

Methodology We attempted to document all available information on fishing techniques that have been used to reduce non-target wildlife species bycatch in world fisheries. Information on bycatch reduction methods is highly diffuse and for this review we consulted various sources including journal articles, unpublished government reports, and experts in the field. A number of reviews have examine...

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 effects of climate and fishing on marine ecosystems have usually been studied separately, but their interactions make ecosystem dynamics difficult to understand and predict. Of particular interest to management, the potential synergism or antagonism between fishing pressure and climate forcing is analysed in this paper, using an end-to-end ecosystem model of the southern Benguela ecosystem,...
