Research ArticleOpen accessIn the abstractA Case Study of River Rehabilitation for Fish in Northern Italy: The Panaro River ProjectClaudio Comoglio, Enrico Pini Prato, Mauro Ferri, Massimiliano GianaroliThe restoration of longitudinal connectivity of a watercourse altered by man-made obstacles is a key issue for the protection and safeguard of freshwater ecosystems and the construction of fish passes constitutes a relevant ad hoc measure. However, in many countries, like Italy, there is still not an adequate technical-scientific background and experience in this field and therefore several migratory species … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,027 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioeconomic Management and Fishing Selectivity: An Application to the European Hake FisheryM. Dolores Garza-Gil, Manuel M. Varela-LafuenteThe bioeconomic management in a fishery with intra-species selectivity is examined. As opposed to other works, we consider a model in which the fishing technology affects resource`s growth not only through the production function, but also through the natural growth rate of the marine resource. The analysis is applied to the European Southern hake stock (merlucius merlucius). The activity of … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 2 · 30 Jun 2007 · 7,453 accessesView PDFCite
