Krill are the subject of growing commercial fisheries and therefore management is necessary to ensure long-term sustainability. catch limits, set by Commission for Conservation Antarctic Marine Living Resources, based on absolute krill biomass, estimated from acoustic-trawl surveys. In this work, we develop a method determining an error budget surveys which includes sampling measurement variabi...

This study characterized the fishery dynamics of blue whiting, a bycatch species bottom trawl Norway lobster fishery, in NW Mediterranean. Landings and effort data over last two decades were combined with current information on spatial distribution catch, size age structure whiting year. Recruitment to demersal habitat occurred from 5 cm total length (TL) shelf break spring (April-May), when di...
This paper presents size structure by sex and length-length relationships for Carcharhinus falciformis Sphyrna lewini caught an artisanal fishery in the Gulf of Tehuantepec, Mexico. According to a local processing practice this fishery, when sharks are landed, their jaws removed but not heads. The orbit-fork length was evaluated as basis estimating total length. A good fit (r2 > 0.9) linear ...
