The U.S. Atlantic large coastal shark fishery grew rapidly during the 1980s when commercial landings increased from 135 metric tons (t) in 1979 to a high of 7122 t in 1989 (NMFS, 1993). In 1993, a quota of 2750 t was established; in 1997 this quota was halved to 1375 t in order to rebuild depleted shark stocks. This fishery targets several species of sharks that are valued for fins (exported to...

Multidimensional Fishery Time Series database stores fishery time series data regarding different aspects of Greek fishery sector such as economical, technical, biological, space and time and it is used for carrying out sustainability and risk analysis of Cephalopods catch quantity in Greece. Economically the most important Cephalopods species Octopus seems to be sustainable for the last four y...

Many fisheries are potentially very valuable. According to a recent report by the World Bank and the FAO (2008), global fisheries rents could be as high as US$ 40-60 billion annually on a sustainable basis. However, according to the report, due to the “common property problem”, most fisheries of the world are severely overexploited and generate no economic rents. The Lake Victoria Nile perch fi...

Climate change can strongly influence coral reef ecosystems, affecting species composition, growth rates, and reef morphology, potentially leading to altered wave energy dissipation across reefs. Sea level rise can also alter wave dissipation, which may lead to shifts in alongshore sediment transport gradients, thereby altering erosion and accretion patterns on tropical coastlines. Delft3D was ...

Targets for improvements in water quality entering the Great Barrier Reef (GBR) have been set through the Reef Water Quality Protection Plan (Reef Plan). To measure and report on progress towards the targets set a program has been established that combines monitoring and modelling at paddock through to catchment and reef scales; the Paddock to Reef Integrated Monitoring, Modelling and Reporting...

For any spatially explicit management, determining the appropriate spatial scale of management decisions is critical to success at achieving a given management goal. Specifically, managers must decide how much to subdivide a given managed region: from implementing a uniform approach across the region to considering a unique approach in each of one hundred patches and everything in between. Spat...

In this study, we consider the effects of marine environmental factors on the spatial distribution of Ommastrephes bartrami in the western North Pacific Ocean during the period in which the commercial squid fishery operates. Spatial referenced fishery data and satellite-derived advanced very high resolution radiometry (AVHRR) sea surface temperature (SST) data, Sea-viewing Wide Fieldof-view Sen...

This paper considers the dynamic producer and consumer benefits from improving habitat that supports a commercial fishery under two different fishery management institutions. By coupling state equations that represent the effects of estuarine eutrophication on fish populations with a multispecies, two-patch spatial bioeconomic model that endogenizes output price through residual demand, the ana...

Game theory is an analytical tool for modeling strategic interaction between agents. Strategic interaction in fishery is interpreted as the harvest by one agent highly affects other agents’ decision. This paper is a commented literature study on the fishery economics and game theory. It tends to describe how fishery models using game theory are build up. These models consist of an underlying bi...

During the 1960s and 1970s, a significant groundfish fishery existed in the Gulf of Mexico. There were about 50 vessels in the fishery which targeted a groundfish complex that consisted of over 170 species, dominant of which were croaker, spot, seatrout, cutlassfish, sea catfish, porgies, perch, drums, hake, and butterfish. The primary directed fishery was for the pet food, harvesting 50,000 to...
