The evaluation of fish stocks exploitation is a complex task that comprehends the analysis of several types of data including information on the spatial and temporal dynamics of commercial fishing fleets. Satellite-based Vessel Monitoring Systems (VMS) is one of the best independent data sources available that can provide information on fishing fleet operations. This type of system allows the t...

In the Hawaii-based longline fishery, changes in fishing operations to target different species produce changes in the effectiveness of fishing effort units. Catch-per-unit-effort (CPUE) indices used in resource monitoring were improved by segregating dissimilar types of fishing effort. Cluster analysis was used to classify longline sets in relation to species composition of the catches. Based ...

A statewide economic survey of Hawaii’s fishing vessel operators was conducted in 1995–96. Survey topics fell into five groups: vessel characteristics, owners’ motivations, fishing operations, cost and revenue information, and operator demographics. Although this project was designed for and emphasizes the costs and earnings of commercial pelagic fishermen, information was also collected from r...

Quantitative analyses of the pink shrimp (Farfantepenaeus brasiliensis and Farfantepenaeus paulensis) fisheries were carried out using data collected from July 1999 to July 2001 from the trawling operations of the fishing fleet based in Santos/Guarujá, SP. According to classical models, the fishery is at its maximum sustainable yield. Therefore, reduction of the fishing effort and adequate seas...

Slickline fishing, as a result of undesired event, is economically preferable compared to workover. However, the fact that it does not always end with success but also worsened situation making risk management strategy. This research aims manage during normal slickline avoid fish and while performing fishing operations using three-round Delphi study conduct identification determine countermeasu...

Mobility of labour across the country continues as a major source supply in ensuring economic development all sectors including primary sector. The migrant search better employment emancipates living conditions through meaningful and financial status. coastal states Maharashtra with commendable marine fish landings provides provide ample opportunities for fishing year. labors are involved harve...

This study was conducted for determining the conditions of hooks after fishing operations in May 2011 – June 2012 on the coasts of Dardanelles Strait and Gallipoli Peninsula. Twenty longline operations with three replication were carried out between 5 and 500 m sea depth. Each longline consisted of 200 hooks. 60000 m of fish line was outspread with a total of 12000 hooks and a total of 1360 ind...

Before the 1970s, the United States sometimes disposed of at sea excess, obsolete, or unserviceable munitions, including chemical munitions. Chemical munitions known to have been disposed of at sea included munitions filled with sulfur mustard, a vesicant (i.e., an agent that causes chemical burns or blisters of the skin and mucous membranes). Signs and symptoms of exposure to a mustard agent c...
