Эколого-географическая гипотеза происхождения крупной черноморской ставриды (Pisces, Carangidae) IBSS Repository
Зуев, Г. В.; Мельникова, Е. Б..
На основе сведений о пространственных, структурно-функциональных и экологических характеристиках крупной ставриды (КС) и их изменчивости в связи с условиями среды обитания, предложена эколого-географическая гипотеза о происхождении КС и причинах ее массового появления в Черном море в конце 40-х годов XX в. Согласно данной версии, КС является результатом вторичного скрещивания между черноморским (Trachurus mediterraneus ponticus Aleev) и средиземноморским (T. mediterraneus mediterraneus Steind) подвидами, которое имело место в Черном море, куда средиземноморская форма проникла в наиболее маловодном за более чем 60-и летний период 1943 г. Высокая жизнеспособность первых поколений КС, характеризуемая поистине гигантскими (на фоне родительских форм) размерами...

An Economic and Sectoral Study of the South African Fishing Industry OceanDocs
Mather, D.; Britz, P.J.; Hecht, T.; Sauer, W..
The introduction of constitutional democracy in South Africa required the redrafting of most Acts of parliament to promote goals of social equity and redress of the consequences of past racial discrimination. The introduction of the Marine Living Resource Act of 1998 required the State to “restructure the fishing industry to address historical imbalances and to achieve equity within all branches of the fishing industry”, but provided no specific strategic policy guidelines for achieving this end. The initial burden of implementing this social agenda fell on government fisheries biologists and a series of interventions with profound economic, legal and political consequences were embarked upon without any proper framework for understanding the expected...

Note de conjoncture OceanDocs
L’analyse des résultats de la pêche artisanale, des sites sous revus, au premier semestre 2012, révèle une hausse globale de 13% des débarquements et de 15% de la valeur commerciale estimée (VCE) par rapport à la même période de 2011. Le sous secteur de la pêche industrielle, à l’exception de la pêche sardinière qui n’a pas fait l’objet de d’analyse dans cette note par faute de données disponibles, se caractérise par une baisse des débarquements de la pêche chalutière de 33% et une production de 1403,71 tonnes de la thonière au premier semestre 2012 comparativement à la même période de 2011 qui n’avait pas enregistré de débarquements. La transformation artisanale au niveau du site de Joal est marquée par une faible baisse de 4% de la production. Cette...

Women in fishing activity: A look at the contribution of the platoneras of Buenaventura, Colombia Boletín de Investigaciones
Garay Tapias,Andrea; Contreras Araque,Andrea; Escobar Toledo,Fabián.
ABSTRACT An analysis of the value chain of the trawl fishery in the Pacific, showed that more than 50 % of the jobs generated in this fishery are occupied by women, and that half of these are provided by the platoneras of the Buenaventura district. The platoneras are afro-descendant women who market fish products based on the bycatch of this fishery and who are an integral part of the trawl fishery. Ignoring the contribution to the local economy and the fishing sector, this study describes the role of platoneras in the trawl fishery to map the value chain sensitive to gender and nutrition. For this, 123 direct surveys to platoneras in five marketing points of the district were applied. The analysis showed that they receive an average of $87,500 COP per...
