Spatio-temporal distribution pattern of the red band-fish Cepola rubescens Linnaeus at different stages of its life cycle in the northwestern Mediterranean

The larvae of Cepola rubescens Linnaeus, 1766 were collected from May to October with a surface temperature of 17.5°C at the beginning of the spawning. They were widely distributed over the continental shelf and the greatest concentrations were found at stations with depth around 100 m. During all months, most of the larvae were of small size, between 2.0 and 3.0 mm s.l . The juveniles and adults were caught in a wide range of depths, from less than 25 m to about 200 m, and the highest abundance was also found at depths of about 100 m, but no large individuals were found at depths less than 50 m. The catches of the trawling fleet showed a marked seasonality, with maximum values at the end of spring and minimum at the end of autumn and the beginning of winter. This seasonality seems to be related to reproduction since the highest catches were obtained during the spawning period.
