Scallop settlements were examined over a 16 month period using collect
ors placed in the sea at 28 day intervals near Torre la Sal Beach, Cas
tellon, Eastern Spain in the western Mediterranean. Collectors were se
t over depths of 20 m and five species, Flexopecten flexuosus, Chlamys
varia, Aequipecten opercularis, Pecten jacobaeus and Palliolum incomp
arabile, were collected. The most frequent species, F. flexuosus, had
peak settlements in August 1992 and in July 1993. C. varia had peaks i
n April and July 1992 and in June 1993. Both of these species settled
throughout the year, except in winter. A. opercularis settled predomin
antly from February to June and in October, but with a few settlements
during the rest of the year. Pecten jacobaeus had a small peak in Feb
ruary and another peak from April to July. P. incomparabile spat were
rare. Settlements were studied in relation to chlorophyll a, suspended
particulate and sea temperature data in the area of study.
