Abstract

This study provides for the first time an evaluationof the natural availability of scallop seeds alongthe coastal area of Taranto (Mediterranean Sea,Southern Italy). To select the best artificial collectorsto harvest scallop seeds in this area, cylindricalcollectors (Cyl) were compared to traditional‘Japanese-style onion bags’ (Bag) across three sites.Scallops represented 26.6% of total bivalve recruitmentamong all collectors (782 ± 331 ind. m-2, The most recruited scallops were Flexopecten glaberand Mimachlamys varia. The white (F. glaber) andblack scallops (M. varia) were abundant at allthree sites, while the queen scallop, Aequipectenopercularis, was only found at one site. Beyond therecruitment of scallops, numerous other potentialcommercial bivalve species were collected, includingLimaria tuberculata, which was the most abundantbivalve species (33.3% of total recruitment).At all sites, Bag collectors had higher recruitmentthan Cyl collectors. Scallops recruited in artificialcollectors exhibited a multicohort size distributionat most sites, suggesting potentially continuousreproductive activity in the scallop populations.F. glaber, M. varia and L. tuberculata could be goodcandidates to diversify the aquaculture productionbecause of the availability of seed and their growthrate. Moreover, the farming of these bivalves integrateswell with other forms of aquaculture (e.g.mussels), thus potentially offering farmers an additionalsource of income.
