Última Analisis de la captura incidental asociada a la pesqueria de vieira patagónica Zygochlamys patagonica OceanDocs Bremec, C.; Lasta, M.L.; Lucifora, L.O.; Valero, J.. The faunistic composition of invertebrate by-catch associated with the Patagonian scallop Zygochlamys patagonica fishery before its development were studied. Analyzed material was sampled from catches performed in different beds with the F/V Erin Bruce during 1995, all of them in undisturbed areas, in the Argentine continental shelf. Macrofaunal species were identified, weighted and percentages of presence estimated. By-catch invertebrate species were determined for every bed, mainly invertebrates without present commercial value. This baseline information is considered a useful tool to detect structural changes in the benthic communities in relation to the conservation of possible substrates of recruitment of this resource and to estimate the evolution of...

En la III y IV Regiones las áreas de manejo y explotación de recursos bentónicos (AMERB) se han establecido como la principal herramienta de manejo del recurso loco (Concholepas concholepas). Sin embargo, su aplicabilidad para la administración y aporte en términos del desarrollo sustentable, aunque sugerentes, requieren de una evaluación objetiva, en cuanto al manejo de carácter discreto que se ha establecido para cada AMERB, desconociendo la eventual interacción espacial de las mismas. En este marco, se desarrolla una aproximación para evaluar el desempeño de las AMERBs desde una perspectiva integral bajo un enfoque metapoblacional. Si bien el estudio está orientado a proporcionar la información de campo que permita probar la hipótesis de metapoblaciones...

Ano: 2005 URL: http://hdl.handle.net/1834/1754 Uso de técnicas geoestadísticas en la estimación de la abundancia de vieira patagónica (Zygochlamys patagonica). OceanDocs Lasta, M.L.; Hernandez, D.R.; Bogazzi, E.; Burgos, G.; Valero, J.; Lucifora, L.O.. To evaluate absolute biomass, a research cruise was conducted on three scallop (Zygochlamys patagonica)beds (38°S-56°W, September 1998). The estimated bed surface was 1,162 nm(2). Sampling stations were regularly spaced at 5 nm intervals. A total of 118 trawls were performed with a non-selective dredge 2,5 m wide (efficiency 16-21. ). Trawls duration and speed were 10 minutes and 3 nm.h(-1)respectively. Samples were taken to estimate total and commercial (greater or equal than 55 mm total height)scallop weight and size frequency distribution. Coefficients of variation (CV)of the estimated biomass were calculated for each bed using geoestatistical techniques and a simple random sampling alternative with the same number of samples. The CVs for total scallop... Tipo: Journal Contribution Palavras-chave: Fishery surveys; Scallop fisheries; Biomass; Abundance; Biomass; Http://aims.fao.org/aos/agrovoc/c_926.
