Fisheries research has traditionally been largely concerned with direct interactions between fishing activ ities and individual fish stocks with a view of optimizing yields. This single species approach has been the basis for the common fisheries policy of the EEC aimed at managing fish stocks by means of catch quota. Although exploitation is undoubtedly a most important factor in the populatio...

Complex dynamics of animal populations often involve deterministic and stochastic components. A fascinating example is the variation in magnitude of 2-year cycles in abundances of pink salmon (Oncorhynchus gorbuscha) stocks along the North Pacific rim. Pink salmon have a 2-year anadromous and semelparous life cycle, resulting in odd- and even-year lineages that occupy the same habitats but are ...

Homologies of minicircle kDNA of 27 Mexican stocks were studied by cross-hybridization with four kDNA probes derived from three reference stocks belonging to groups Trypanosoma cruzi I (SO34 cl4 and Silvio) and T. cruzi II (MN) and one Mexican stock. High homologies were only observed with Silvio (six stocks) and Mexican probes (11 stocks). After 30 min exposure (low homology) additional stocks...

OBJECTIVE Despite widespread concern over exploitation of the European Union's fish stocks, dietary guidelines in the UK continue to recommend two portions of fish per week. The present study sought to investigate whether health and/or sustainability are motivating factors when purchasing and consuming fish and whether there are sociodemographic trends. DESIGN A structured, self-completion po...

Available online 30 April 2015 This paper tests the relation between expected excess stock returns and illiquidity risk in G7 markets. By conducting panel regressions on monthly data for 20 years, evidence shows that excess stock returns of the G7 countries are positively correlated with market illiquidity risk, but are negatively correlated with the innovation of firm-level illiquidity. Applyi...

Here we present a case study toward producing quantitative scientific advice on the application of the EU Common Fisheries Policy (CFP) in the Black Sea. We provide estimates of fishing mortality rates at levels which will lead to rebuilding and maintaining stocks above biomass levels that could produce maximum sustainable yield (MSY) under the IPCC RCP4.5 future climate scenario together with ...

The monetary policy in the frame of monetary transaction through stocks market affects the stocks’ price that these prices also affect the economy with impacting consuming and investing expenses. In another word, based on the importance of monetary part in commercial banks, the effect of these policies on bank stocks has a great importance that is studied in his project. For this purpose, the d...
