description The present work was carried out at the Aguamilpa dam from August 2000 to December 2001, with a duration of one and a half years. The objective of the work was to propose technological improvements to the gillnets used in the area for the commercial capture of tilapia, catfish and lobster, species regularly caught and commercialized by fishermen. The study included field sampling of commercial catches, as well as echnological analysis of the nets used for this purpose, such as catch efficiency and selectivity. In order to contrast the results obtained in the commercial capture of the species in question, 9 nets were constructed with different mesh sizes with technical characteristics recommended by the FAO. for the capture by gillnet of Sierra and Tilapia. These were operated in the same fishing sites for analysis and comparison of their operating characteristics with respect to commercial nets during an annual cycle! The results obtained showed that the most efficient nets in terms of capture, with sizes and weights suitable for commercialization, were 4" and 4 W . In order to make decisions, it was considered necessary to guarantee the production of the species with the consequent commission of small sizes, which will allow their recruitment to the fishable stock. The 4" and 4" and," nets are recommended for commercial fishing in Aguamilpa point at which the results of this work coincide with the official Mexican standard for tilapia fishing in reservoirs. From these results were proposed technological improvements that were considered for the construction of a prototype net that incorporates the criteria of a planned and responsible fishing.

EI objetivo del trabajo fue el de proponer mejoras tecnológicas para las redes de enmalle utilizadas en la zona para la captura comercial de tilapia, bagre y lobina, especies regularmente capturadas y comercializadas por los pescadores. EI estudio comprendió el muestreo en campo de las capturas comerciales, asl como el análisis tecnológico de las redes utilizadas para este propósito, tales como la eficiencia de captura y selectividad de las mismas. Para contrastar los resultados obtenidos en la captura comercial de las especies en cuestión se construyeron 9 redes con diferentes tamaños de malla con características técnicas recomendadas por la FAO. para la captura por enmalle de Sierra y Tilapia. Estas fueron operadas en los mismos sitios de pesca para el análisis y comparación de sus características de operación con respecto a las redes comerciales durante un ciclo anual!. Los resultados obtenidos mostraron que las redes más eficientes en cuanto a su captura, con tallas y pesos adecuados para comercializar, resultaron ser las de 4" y 4 W . Para la toma de decisiones se consideró necesario garantizar la producci6n de las especies con la consecuente comisión de tallas pequeñas, 10 cual permitirá su reclutamiento al stock pescable. Las redes de 4" y 4 y," . son recomendadas para la pesca comercial en Aguamilpa punto en el cual los resultados de este trabajo coinciden con la norma oficial mexicana para Ia pesca de tilapia en embalses. A partir de estos resultados se propusieron mejoras tecnológicas que fueron consideradas para la construcción de un prototipo de red que incorpore los criterios de una pesca planificada y responsable.Universidad Autónoma de NayaritGONZALEZ VEGA, ALVARO2019-06-05T18:48:09Z2019-06-05T18:48:09Z2003info:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/publishedVersionhttp://dspace.uan.mx:8080/jspui/handle/123456789/1991reponame:Repositorio Institucional Aramara de la UANinstname:Universidad Autónoma de Nayaritinstacron:UANspaCONACYTPúblico en generalinfo:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/cc-by-nc-saoai:dspace.uan.mx:123456789/19912024-08-28T03:18:58Z
