Shark breeding grounds and seasons in the Gulf of California: Fishery management and conservation strategy

Sharks show high biological fragility and, given the intense fishing regimes to which they are exposed in the Gulf of California, it is necessary to establish a conservation and management strategy providing for the protection of their nursery areas. We reviewed the literature concerning shark repro...

description	Sharks show high biological fragility and, given the intense fishing regimes to which they are exposed in the Gulf of California, it is necessary to establish a conservation and management strategy providing for the protection of their nursery areas. We reviewed the literature concerning shark reproductive biology to determine priority management areas in the Gulf of California by complementarity analysis and different selection criteria. Four levels of management and conservation priority were determined for six quadrants: level 1 corresponded to the area off Mazatlán (Sinaloa) and the area of El Sargento, La Ventana, and Punta Arenas (Baja California Sur); level 2 to the areas of Teacapán (Sinaloa) and Seri (Sonora); level 3 to the areas of San Francisquito-El Barril (Baja California) and Kino Bay (Sonora); and level 4 to the area of La Manga (Sonora). Analysis of space-time variables in a geographic information system indicated that 71% of the commercially important shark species concentrate in coastal zones, mainly in bays, coastal lagoons, estuaries, and wetlands (central and southern Gulf of California) during spring and summer (May–August), except for Prionace glauca, Isurus oxyrinchus, Alopias pelagicus, and Squatina californica that reproduce in winter and spring. The protection of recruitment areas (critical habitats) during peak breeding periods should be an essential part of any resource management plan.

Se realizó una revisión de literatura existente en relación a la biología reproductiva de los tiburones para localizar áreas prioritarias de manejo en el Golfo de California mediante análisis de complementariedad y diversos criterios de selección. Se encontraron seis cuadrantes en cuatro niveles de prioridad de manejo: el nivel 1 incluyó la zona adyacente a Mazatlán(Sinaloa) y el área de El Sargento, La Ventana y Punta Arenas (Baja California Sur); el nivel 2 las zonas de Teacapán, (Sinaloa) y seri (Sonora); el nivel 3 las zonas de San Francisquito-El Barril (Baja California) y Bahía Kino (Sonora); y el nivel 4 la zona de La Manga (Sonora). El análisis de las variables espacio-tiempo en un sistema de información geográfica indicó que 71% de las especies de tiburones de importancia comercial se concentra en la zona costera, principalmente en bahías, lagunas costeras, estuarios y marismas (regiones central y sur del Golfo de California) durante la temporada primavera-verano (mayo a agosto), excepto Prionace glauca, Isurus oxyrinchus, Alopias pelagicus y Squatina californica, que se reproducen en invierno y primavera. La protección de estas áreas críticas de reclutamiento (hábitats críticos) en las temporadas de máxima reproducción y crianza debe ser parte fundamental del plan de manejo del recurso. 2009-12-08 2021-06-03T03:55:16Z 2021-06-03T03:55:16Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1435 10.7773/cm.v35i4.1435 https://hdl.handle.net/20.500.12930/7423 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1435/1784 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 35 No. 4 (2009); 369-388 Ciencias Marinas; Vol. 35 Núm. 4 (2009); 369-388 2395-9053 0185-3880
