agunmukha river is an important water body having plentiful aquatic resources. the fisheries communities in the river are familiar with a diverse range of fishing gear and crafts to catch fish. therefore, the objectives of the present study were to explore fishing gear and fishing crafts, catch composition of the respective gearand identification of fish biodiversity of agunmukha river. a step ...

the present study considered the situation of kilka stocks in last decades by using overfished biomass threshold, fishing effort ratio and fishing mortality proxy during 1991-2010. the cpue index of anchovy and mixed-species of kilka indicated an undepleted from 1991 to 2000. in 2000, the cpue ratio declined to close to the “in danger” region, and subsequently collapsed to “overfished” region f...

We developed a transdisciplinary modeling approach for the Huave Lagoon System (HLS), Mexico. This lagoon was selected because it has been used sustainably in various complimentary ways by different ethnic groups since pre-Hispanic times. Over the last few years, however, the ecological impact of artisanal fisheries in the region has grown significantly, thus endangering the balance between soc...

Examining society’s preferences for any change in the status of wetlands, can translate their direct and indirect benefits into monetary values and provide useful information for the policy makers and planners. Hoor-al-Azim Wetland (also Hoor-al-Hoveizeh) is one of the four large wetlands with an area of over 125 thousand hectares located in Khuzestan province located in southwestern Iran on it...

The objective of this paper was to study angling from September, 2002 to September, 2004 in the Lobo-Broa Reservoir, Itirapina, SP (22 degrees 15' S and 47 degrees 49' W). Interviews (total 1,027) with sport fishers were accomplished in the three main fishing sites (Horto, Píer and Praia). This fishing was practiced with a simple fishing rod and reel, mainly in Horto, where the catches and fish...

Biodiverse coastal zones are often areas of intense fishing pressure due to the high relative density of fishing capacity in these nearshore regions. Although overcapacity is one of the central challenges to fisheries sustainability in coastal zones, accurate estimates of fishing pressure in coastal zones are limited, hampering the assessment of the direct and collateral impacts (e.g., habitat ...

There is ongoing pressure to develop the largely unaltered Daly River catchment in northern Australia for agriculture. However, a choice experiment among people in the region and in Australia's largest city, Sydney, shows that people are prepared to pay substantial amounts to maintain the quality of its ecosystem services. The total stated willingness-to-pay (WTP) for a Daly River conservation ...

Predators commonly share prey with human exploiters, intuitively suggesting that there is an inherent human–predator conflict through competition for prey. Here we studied the effects of fishing and predation mortality on biomass distributions and yields of shared prey using a size-structured model of competing populations, describing the life histories of Baltic Sea sprat and herring. Whereas ...
