Resumen
A nivel mundial los cefalópodos son un recurso pesquero de alto interés económico a nivel costero, dentro de este grupo se encuentra la familia Octopodidae que alberga al género Octopus, el cual es el que sobresale de esta familia por su importancia pesquera y su gran variedad de especies a nivel mundial, la falta de una regulación de captura mínima nos ha permitido estudiar la distribución de la población en aguas territoriales. Durante Julio - Diciembre del 2013 en la Reserva de Producción Faunística Marino Costera Puntilla de Santa Elena (REMACOPSE) se analizaron 4007 individuos en los que se registró la Longitud Dorsal del Manto (LDM, cm), Peso Total (PT, g.), Sexo y Estado gonadal, la proporción sexual no mostró diferencias significativas (JI2, p), los machos tuvieron una variación de talla entre 0.60 y 23 cm LDM y un promedio de 13.23 cm LDM, las hembras mostraron un rango de talla entre 6 a 25 cm LDM y un promedio de 13.86 cm, el peso de los machos varió de 317.1 g y 3175.1 g y un promedio de 775.64 g. Los machos mostraron un peso máximo de 3178 g en Julio y un mínimo de 45.4 g en Diciembre, las hembras mostraron un peso máximo de 81.72 g y un mínimo de 3187.08 g ambos en Octubre. De acuerdo a la madurez sexual prevalecieron las hembras inmaduras y los machos maduros.
Worldwide cephalopods are a fishery resource of high economic interest to coastal level in Ecuador its artisanal fishery is unregulated and the lack of a biological basis - fishing is not allowed to know the distribution of the population in territorial waters. During July-December 2013 in the Wildlife Production Reserve Marino Costera Puntilla Santa Elena (REMACOPSE) 4007 individuals in whom the mantle length (LDM, cm) Total Weight (. PT, g) was recorded were analyzed, state gonadal sex, the sex ratio showed no significant difference (JI2, p), males had a variation in size between 0.60 and 23 cm LDM and LDM average of 13.23 cm, females showed a size range between 6-25 LDM cm and an average of 13.86 cm, the weight of males ranged from 317.1 g 3175.1 g and an average of 775.64 g. Males showed a maximum weight of 3178 g in July and a minimum of 45.4 g in December, females showed a maximum weight of 81.72 g and a minimum of 3187.08 g both in October. According to sexual maturity they prevailed immature females and mature males.
