LONG-TERM RESEARCH As we conduct fieldwork and process samples in the lab afterwards, we often ponder what the real sample size is. We measured hundreds or thousands of fish, shrimp, clams, or whatever it is that we work on. These seem like adequate sample sizes until we remember that they were all collected at a... Read More
ABSTRACT: Despite the conspicuous character of sawfish (Pristis spp.) in shallow estuarine waters, current records in the southern Gulf of Mexico are so scarce that they have been declared locally extinct from many areas where they formerly occurred (Fernandez-Carvalho et al. 2013). In Mexican waters of the Gulf of Mexico, historical reports for sawfish exist for... Read More
RESUMEN: La lamprea del Pacífico (Entosphenus tridentatus) ha sido parte esencial de la comunidad ecológica y ha co-evolucionado con especies acuáticas de los ríos del oeste de los EE.UU. La falta de información sobre la lamprea del Pacífico ha entorpecido los esfuerzos de manejo y conservación. Con el fin de evaluar y conservar la lamprea... Read More
Pacific Lamprey (Entosphenus tridentatus) have been an important part of the ecological community and co-evolved with aquatic species of the western rivers of the United States. Scarce information on Pacific Lamprey has hindered conservation and management efforts. To assess and conserve Pacific Lamprey, we developed a conservation initiative composed of three parts: assessment, conservation agreement,... Read More
Aprendiendo manejo y manejando el aprendizaje: sostenibilidad de pesquerías recreativas de agua dulce en un ambiente cambiante RESUMEN: Los cuerpos de agua dulce están siendo transformados por múltiples factores ambientales, lo que genera incertidumbre sobre lo que sucederá en el futuro. Una forma de enfrentar esta incertidumbre es el manejo de la resiliencia con respeto... Read More
Learning to Manage and Managing to Learn: Sustaining Freshwater Recreational Fisheries in a Changing Environment ABSTRACT: Freshwaters are being transformed by multiple environmental drivers, creating uncertainty about future conditions. One way of coping with uncertainty is to manage for resilience to unanticipated events while facilitating learning through adaptive management. We outline the application of these... Read More
RESUMEN: Los Sistemas de Información Geográfica (GIS) son una herramienta poderosa para el análisis e interpretación de datos espaciales comúnmente encontrados en la ciencia pesquera. Se presentan los detalles del uso del GIS en el manejo de pesquerías aplicado en un estudio previo, encontrando que el costo era un factor que limitaba el uso del GIS. En... Read More
ABSTRACT: Geographic information systems (GIS) are powerful tools for analysis and interpretation of spatial data commonly encountered in fisheries science. We presented details of GIS use in fisheries management in a prior study and found cost to be a factor limiting GIS use. This article introduces fisheries managers to free or open-source GIS. Free or open-source GIS are... Read More
RESUMEN: El monitoreo de actividades pesqueras es un componente esencial en las pesquerías manejadas adecuadamente y puede ofrecer datos verificables, dependientes de la pesquería, acerca de las actividades de pesca y ayuda a evaluar el desempeño y éxito de los planes de manejo. Manejadores e involucrados en las pesquerías suelen batallar con el desarrollo e implementación de programas efectivos de... Read More
ABSTRACT: Monitoring of fishing activities is an essential component of successful fisheries management that can provide verifiable fishery-dependent data on fishing activities and help assess performance and success of fisheries management plans. Fishery managers and stakeholders have often struggled in developing and implementing effective monitoring programs due to lack of information, funding, and peer-to-peer learning from existing monitoring programs....
