Length–weight relationship and condition factor for 7 loliginid squid species in Mexican waters

Length–weight relationship and condition factor for 7 loliginid squid species in Mexican waters

The length–weight relationship and the condition factor are key parameters in stock assessment. Despite the fisheries potential loliginid squids have in Mexico, the group is scarcely known and no formal management has been implemented. A total of 1,105 squids captured on the Pacific and Atlantic coa...

Despite the fisheries potential loliginid squids have in Mexico, the group is scarcely known and no formal management has been implemented. A total of 1,105 squids captured on the Pacific and Atlantic coasts of Mexico were measured to estimate length–weight relations and condition factors. Except for Lolliguncula brevis and Lolliguncula argus, all species showed negative allometric growth. The 2 species with isometric growth showed a poor condition, according to Fulton’s condition factor, and the rest of the species were in good health, according to the relative condition factor. The type of growth exhibited by the species identified in this study could be associated with their swimming habits or otherwise be affected by the same variables that determine the type of growth of other squid found in Mexican waters. The parameters evaluated in this research are now available for incorporation in further fishery stock assessment models for loliginid squids. La relación longitud-peso y el factor de condición son parámetros primarios en la evaluación de poblaciones pesqueras. A pesar del potencial pesquero de los calamares loligínidos en México, el grupo es escasamente conocido y no hay un manejo formal implementado. Un total de 1,105 calamares capturados en aguas mexicanas del Pacífico y del Atlántico fueron medidos para estimar la relación longitud-peso y los factores de condición. Excepto Lolliguncula brevis y Lolliguncula argus, todas las especies presentaron crecimiento alométrico negativo. Las 2 especies con crecimiento isométrico presentaron una condición pobre, según el factor de condición de Fulton, y el resto de las especies presentaron buena condición de salud, según el factor de condición relativo. El tipo de crecimiento encontrado en las especies identificadas en este estudio puede estar relacionado con sus hábitos de nado o, de otra manera, puede ser afectado por las mismas variables que determinan el tipo de crecimiento de otros calamares encontrados en aguas mexicanas. Los parámetros evaluados en esta investigación ahora se encuentran disponibles para ser incorporados en futuros modelos de manejo de poblaciones pesqueras de calamares loligínidos.
