“…Once it reaches the first sexual maturity, weight gain increases due to reproduction requirements (gonad weight and fat storage), combined with young fish migration towards adult areas. These results have differences in weight according to the quality and amount of food consumed (Allen 1985, Sheaves 1995, Madrid & Sánchez 1997, Gallardo-Cabello et al 2007, Espino-Barr et al 2008. In the present paper the more active feeding periods, represented by values of gastric repletion (GRI) correspond to months of spring and summer, when the availability of food is higher due to a higher temperature and photoperiod.…”

Resumen.-Se estudian algunos aspectos biológicos de Lutjanus peru (Pisces: Lutjanidae) recolectado en la Bahía Bufadero, Michoacán, México. El análisis de escamas permitió identificar cuatro anillos de crecimiento, valores similares fueron obtenidos por medio de los estimadores de densidad de Kernel. Los resultados de la ecuación de crecimiento de von Bertalanffy obtenidos por el método lineal simple fueron: L ∞ = 81,12 cm, W ∞ = 4.839 g, K= 0,24 años-1 y t o =-0,39 años. Los máximos valores del índice de repleción y del factor de condición ocurren durante los meses de febrero, abril y junio. Los periodos de máxima reproducción ocurren durante los meses de febrero y agosto. Los periodos de reclutamiento al área son de enero a julio para los nacidos en agosto, y de agosto a diciembre para los nacidos en febrero. El tamaño de reclutamiento al arte de pesca es de 18 cm. El índice gonadosomático muestra una relación inversamente proporcional en relación al índice hepatosomático. La longitud corporal de L. peru en su primera madurez sexual es de 25,45 cm y su longevidad es de 12 años. El 65,84% de la pesca en Bahía Bufadero es de organismos sexualmente inmaduros, por lo que se propone como talla mínima de captura una longitud de 45 cm (edad 3 años) y un periodo de veda para agosto y septiembre.

Yellowfin Mojarra Gerres cinereus (Walbaum, 1792) off the Mexican Pacific coast is a popular low-cost species, which is caught with gill and cast nets. Knowing breeding seasons, gonadal maturity, fecundity and size at sexual maturity is necessary for fishery management. Samples were obtained from April 2010 to November 2011. Size, sex and gonad maturity were recorded, while the gonadosomatic index and the fecundity and condition factors were calculated using the gravimetric method. To calculate this information by age, growth parameters previously published were used. The female:male ratio was 1:1.024. Mature females were observed year round with two major peaks during July and October. Sexual maturation (L 0.5 ) of males and females was 16.40 cm and 20.20 cm, respectively, corresponding to one-year old organisms. First maturity length (L 0.25 ) was 15.80 cm in males and 16.50 cm in females. The hepatosomatic index vs length was LW = 2.00·10 -6 ·TL 4.213 , resulting in a positive allometric relationship. Condition factor indexes increased during February and September. Average oocyte diameter was 0.31 mm (0.15 to 0.45 mm). Fecundity ranged from 37,784 to 1,746,510 oocytes in females from one to seven years of age, and mean relative fecundity was 1332 oocytes·g -1 (294 to 4,430 oocytes·g -1 ). G. cinereus has an early sexual maturity, reproduces once or twice a year and has a high fecundity rate, which allows it to be caught all year round, if caught after the first maturity length.

“…For example, in Green Jacks from Las Perlas Z=1.9/year and L ∞ =59.2cm, while in those from Colima; Z=2.2/year and L ∞ =51.5-55.4cm. In Caranx caninus, values of Z, also from Colima, decreased on average from 0.79-0.65/year in a decade, while their asymptotic lengths increased from 74.4-104.1cm during the same period (Cruz-Romero et al 1993, Espino-Barr et al 2008.…”

, from landings at the central fish market. Average total length was 36.1±6.4cm and optimum length 38.9cm. Approximately 68% of fish lengths were within ±10% of the optimal length but only six (15%) were considered mega-spawners. The von Bertalanffy parameters describe a long-lived and fast growing species, while mortality rates revealed that C. caballus is under high fishing pressure. Standard length at which half of the population is mature was 38.8cm, and the size at which individuals matured massively, 33cm. Only 10-13% of the fish were immature. C. caballus reproduces two to three times per year, with peaks in December, April, and probably September, and recruits to the population at least twice per year. Catch per unit effort (CPUE) was best predicted by minimum annual values of the Multivariate ENSO/ LNSO Index (MEI) (R 2 =0.54). Results show that C. caballus in Pacific Panama is overfished. We recommend the raising of the minimum capture/landing size of this species in order to increase the proportion of megaspawners in the population and guarantee the sustainability of this resource.
