Different fisheries, even the same fishery, use different ways of quantifying fishing efforts such as number vessels, days, voyages, and hooks. In squid-jigging hours, vessels are valid units for calculating catch per unit effort (CPUE). A vessel monitoring system (VMS) provides position data with high spatial temporal resolution offers possibility to quantify CPUE at a finer scale. Using squid...

The Socotra Archipelago (Yemen), a group of four islands off the north-eastern tip Africa in western Indian Ocean, has population that relies heavily on small-scale fishing for livelihoods and food security. However, reporting fisheries catches by Yemen consistently been incomplete, with artisanal (small-scale, commercial) underreported non-commercial subsistence recreational not reported at al...

In this study, it is aimed to compare the yield and strength of crayfish fyke rigged with knotless net 210d/12 rope thickness those traditional material 210d/6 knotted which widely used in Turkey fishing (Pontastacus leptodactylus, Eschscholtz, 1823). The study was carried out on a monthly basis between June 2017 May 2018. total 300 nets, equipped 150 classical alternative were used. caught cra...

Small-scale fisheries along the Swedish west coast are often operated by using small vessels, targeting multiple species means of pots and gillnets. Fisheries shellfish such as European lobster ( Homarus gammarus) , edible crab Cancer pagurus ) have a relatively high economic value. However, gillnet demersal fish currently diminishing primarily due to depleted stocks increased seal depredation....

14 We report analyses of a dataset spanning 38 years of near-annual fishing for Antarctic toothfish 15 Dissostichus mawsoni, using a vertical setline through the fast ice of McMurdo Sound, 16 Antarctica, 1972-2010. This constitutes one of the longest biological time series in the Southern 17 Ocean, and certainly the longest for any fish. Fish total length, condition and catch per unit 18 effort...

The oyster Crassostrea spp. is one of the main fisheries resources in the southern portion of São Paulo State. This paper aims to evaluate the extractivism of that resource, supplying subsidies to the implementation of management regulations. This study was developed in Cananéia, from February 1999 to December 2006. The oyster production data in dozens was obtained through weekly or monthly int...
