Abstract
The study investigated smooth clam Callista chione (Linnaeus, 1758), collected in July 2010 at 23 sample sites in the Gulf of Trieste. From the results it was found that in some groups, an inverse correlation exists between length- -at-age (estimated from the number of the tiny slowing growth translucent bands with a LED pointer) and sampling depth. The results confi rmed observation from 1992 and 1993 surveys and the environmental features at different depths are still largely unknown. Unfortunately in 2013 and 2014 the clam beds were affected by a mass mortality that could compromise this fi shery in the maritime District of Monfalcone, so a rapid growth assessment could be helpful for fi shermen activity and management decisionPubblicazioni consigliate
