Size, sex and maturity of the squid Lolliguncula diomedeae (Cephalopoda: Loliginidae) in the Gulf of Tehuantepec, México.

There is practically no information on the biology of Lolliguncula (Loliolopsis) diomedeae. We analyzed specimens caught in four shrimp fishing trips in the Gulf of Tehuantepec in 1999-2001, 2004 and 2006.Sexual maturity and gonadosomatic index (GSI) were used as indicators of reproductive activity....

We analyzed specimens caught in four shrimp fishing trips in the Gulf of Tehuantepec in 1999-2001, 2004 and 2006.Sexual maturity and gonadosomatic index (GSI) were used as indicators of reproductive activity. A total of 1 200 individuals were captured, 89% female. Females ranged from 35 to 97mm in mantle length (LDM),with a mode at 80mm and weights 2 to 30,9g; males 20,7 to 65mm LDM with a mode at 35-40mm and weights from 0,4 to 12g. Differences in the LDM and the PT between males and females were significant (KS, p<0,05). The sex ratio was 8:1 H:M (p <0,05). The weight-length relationship type is potential for both sexes, with a negative allometric growth.83% of mature females had high IGS values, in contrast to less than 20% of mature males. The size at first maturity (L50) indicates that males (42,7mm LDM) mature when shorter than females (74,5mm LDM). Maturity, IGS and oceanographic features of the Gulf of Tehuantepec indicate that L. diomedeae spawn there.Practicamente no hay información de la biología deLolliguncula (Loliolopsis) diomedeae. Analizamos especimenes capturados en cuatro viajes de pesca de camarón en el Golfo de Tehuantepec durante 1999-2001, 2004 y 2006. La madurez sexual y el índice gonadosomático (IGS) se utilizaron como indicadores de la actividad reproductiva. Se capturaron un total de 1 200 individuos, 89% hembras. Las hembras presentaron un intervalo de tallas de 35 a 97mm LDM, con una moda en 80mm y pesos de 2 a 30,9g; los machos tallas de 20,7 a 65mm LDM con una moda en 35-40 mm y pesos de 0,4 a 12g. Las diferencias en la LDM y el PT entre machos y hembras fueron significativas (K-S, p<0,05). La proporción de sexos fue de 8:1 H:M (p<0,05). La relación peso-talla es de tipo potencial para ambos sexos, con un crecimiento alométrico negativo. 83% de las hembras maduras se encontraron con valores del IGS altos, en contraste con menos del 20% de los machos. La talla de primera madurez (L50) indica que los machos (42,7mm LDM) maduran a longitudes menores que las hembras (74,5mm LDM). La madurez, IGS y las características oceanográficas del Golfo de Tehuantepec indican que L. diomedeae desova aquí.Universidad Estatal a Distancia, Costa Rica2015-06-05info:eu-repo/semantics/publishedVersionartículo originalhttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/articleapplication/pdftext/htmlhttps://revistas.uned.ac.cr/index.php/cuadernos/article/view/86710.22458/urj.v7i1.867UNED Research Journal; Vol. 7 No. 1 (2015); 79-87UNED Research Journal; Vol. 7 Núm. 1 (2015); 79-871659-441X1659-4266reponame:Portal de Revistas UNEDinstname:Universidad Estatal a Distanciainstacron:UNEDspahttps://revistas.uned.ac.cr/index.php/cuadernos/article/view/867/729https://revistas.uned.ac.cr/index.php/cuadernos/article/view/867/1768Derechos de autor 2022 UNED Research Journalhttps://creativecommons.org/licenses/by/4.0acceso abiertohttp://purl.org/coar/access_right/c_abf2info:eu-repo/semantics/openAccess2022-10-18T18:45:38Zoai:revistas.investiga.uned.ac.cr:article/867Universidadhttp://www.uned.ac.crhttps://revistas.uned.ac.cr/index.php/index/oaissegura@uned.ac.crCosta RicaNo aplicaNo aplicaNo aplicaopendoar:02025-06-01T10:59:47.263Portal de Revistas UNED - Universidad Estatal a Distanciafalse
