Illegal, unreported and unregulated (IUU) fishing activities continue to thrive in the northern region of Australia’s Fishing Zone (AFZ). Indonesian fishermen involved in IUU fishing in this area target specific marine species such as shark, reef fish, sea cucumber and trochus that are destined for the Asian market. Many of these marine species’ stocks are now at critical levels. Local communit...

The Inshore Potting Agreement (IPA) is a voluntary management system conceived by the inshore fishers of south Devon, England. The IPA has functioned effectively since 1978 to reduce conflict between static gear (trap and net) and towed gear (trawl and dredge) fishers. Although there is no legal recognition of the system, the IPA continues to be generally observed by both sectors of the fishing...

Northern anchovy Engraulis mordax, in an upwelling area off the west coast of Baja California, Mexico, had several strategies in response to chlorophyll a distribution and availability. When the pigment was scarce, northern anchovies practically disappeared from the area and they returned to coastal waters when it was abundant. The fish gathered in specific areas where low turbulence mixing and...

In response to our recent paper (1), Szuwalski and Hilborn (2) make several points about the timing of recruitment failures, the effect of fishing on productivity, and our choice of using biomass, not recruitment, as the indicator for collapses. We address these points here to show that not only do they not affect our conclusions, but that we are largely in agreement regarding the biological pr...

the aim of this study was to determine influencing factors on participation of fishermen member cooperative in sustainable fishing in golestan province. the methodological approach of this study was descriptive- correlative. the research population consisted of 144 fishermen who member cooperative, which were selected using census method. validity of the instrument was established by a panel of...

Impact of fishing methods and gears used on fish faunal diversity in spring-fed torrential river Relli in Darjeeling hill area of West Bengal was investigated in the present study. The fish species available in the river provide nutrition and recreation (rarely income generating) fora large number of people residing along the river bank and nearby villages and towns. The fishing methods observe...

Fishing is widely known to magnify fluctuations in targeted populations. These fluctuations are correlated with population shifts towards young, small, and more quickly maturing individuals. However, the existence and nature of the mechanistic basis for these correlations and their potential ecosystem impacts remain highly uncertain. Here, we elucidate this basis and associated impacts by showi...

Adopting the approach taken with New Caledonian crows (Corvus moneduloides), we present evidence of design complexity in one of the termite-fishing tools of chimpanzees (Pan troglodytes) in the Goualougo Triangle, Republic of Congo. Prior to termite fishing, chimpanzees applied a set of deliberate, distinguishable actions to modify herb stems to fashion a brush-tipped probe, which is different ...

We present a stock-effort dynamical model of a fishery subdivided into fishing zones. The stock corresponds to a fish population moving between these zones, on which they are harvested by fishing fleets. We consider a linear chain of identical fishing zones. Fish movements between the zones, as well as vessels displacements, are assumed to take place at a faster time scale than the variation of...

Commercial fishing is a dangerous occupation despite decades of regulatory initiatives aimed at making it safer. We posit that rights-based fisheries management (the individual allocation of fishing quota to vessels or fishing entities, also called catch shares) can improve safety by solving many of the problems associated with the competitive race to fish experienced in fisheries around the wo...
