Última Estudio de edad y crecimiento de la raya hocicuda Dipturus chilensis (Guichenot,1848) en el Atlántico Sudoccidental (34º -55º LS y 52º -69º LW) OceanDocs Zavatteri, A.. This paper deals with the age and growth parameters of the Southwest Atlantic beaked skate Dipturus chilensis, as well as with some reproductive features of the species. Samples of individuals inhabiting 34°-55°S and 52°- 69°W were analyzed. They were taken during surveys carried out by the National Institute for Fisheries Research and Development (INIDEP) research vessels, as well as by a landing sampling at Mar del Plata port. The fish age was determined by counting growth rings from thin sections of the vertebral centra of 414 fish ranging 24-110 cm (203 males) and 24-115 cm (211 females) total length. The vertebral sections were stained using cobalt hloride. Both average per cent error (APE=5.94) and precision (D=5.89) indexes suggested that the...

Estimate of age, growth and natural mortality of longtail hake (Macruronus magellanicus) in the Southwest Atlantic Ocean during summer 2010. Longtail hake (Macurornus magellanicus) total length (TL) and weight (W) growth parameters were estimated and age structure and natural instantaneous mortality coefficient (M) analyzed. Data were obtained within the framework of the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP) “Observers on Board of Commercial Vessels” Subprogramme. The information, derived from the area comprised between 46° S-54° S, was collected during the February-April 2010 period. Sagittae otoliths reading of 5,034 individuals (2,429 males and 2,605 females) between 28-99 cm TL was performed. The maximum ages observed in...
