Summary: The smooth clam Callista chione is an Atlantic-Mediterranean species that is commercially exploited in several European countries. Several aspects of its reproduction were studied in a coastal location of the northwestern Mediterranean as a tool for sustainable fisheries management. Gonadal development was classified into 6 different stages, ranging from immature to degradation of the remaining sexual structures. Results showed that C. chione was able to reproduce throughout the year but a main spawning period occurred in spring. First records of hermaphrodites were found for this species. The mature spermatozoa measured 4.70±0.66 µm (without the flagellum), including a very short acrosome of 0.75±0.09 µm. The mid-piece of the spermatozoa had a mitochondrial sheath composed of five mitochondria. Ripe oocytes ranged from 60 to 80 µm in length. Size at first maturity (SL50) was estimated for the first time in a Mediterranean population, showing values of 30.26 mm in 2005-2006 but only 21.45 mm in 2014.
Keywords: gonads; first maturity; hermaphroditism; Veneridae; commercial mollusks.
Reproducción y talla de primera madurez en un banco de Callista chione explotado en el Mediterráneo
Resumen: La concha fina Callista chione es una especie atlántico-mediterránea comercialmente explotada en distintos paí- ses europeos. Se estudiaron varios aspectos de su reproducción en una localidad costera del noroeste Mediterráneo como herramienta para la gestión sostenible de su pesquería. El desarrollo gonadal se clasificó en 6 estadios distintos, que engloban desde individuos inmaduros a la degradación de las estructuras sexuales remanentes. Los resultados mostraron que C. chione se podía reproducir durante todo el año con un periodo de máxima puesta en primavera. Se observaron hermafroditas de esta especie por primera vez. Los espermatozoos maduros midieron 4.70±0.66 µm (sin el flagelo) incluyendo un corto acrosoma de 0.75±0.09 µm. La pieza media de los espermatozoos estaba compuesta por 5 mitocondrias. Los ovocitos maduros median entre 60-80 µm de longitud. La talla de primera maduración (SL50) se estimó por primera vez en una población del Mediterráneo, hallando valores de 30.26 mm en 2005-2006 pero solamente de 21.45 mm en 2014. Palabras clave: gónadas; primera maduración; hermafroditismo; Veneridae; moluscos comerciales. Citation/Como citar este artículo: Galimany E., Baeta M., Durfort M., Lleonart J., Ramón M. 2015.
