Sažetak
The settlement of molluscs’ larvae of and other biofouling organisms on experimental collectors
was studied, with particular reference Great Mediterranean scallop, Pecten jacobaeus. Three
types of experimental collector made from vegetable sacks, modelled based on the collectors used
in Japan, were placed in four existing fish and shellfish farms located in the Boka Kotorska Bay.
The experimental collectors were placed in the periods June–October and June–December 2017
and the period August 2017–February 2018 and monitored after immersion of four to six months,
respectively. In total, 18 species of molluscs and also 28 species of biofouling organisms were determined.
The most abundant ones found on the collectors were the following shellfish species (68 %) Talohlamys
multistriata, Mytilus galloprovincialis, Modiolarca sp., Anomia ephippium and Limaria hians. The
most abundant group of biofouling organisms were crustaceans (18 percent) with a species of
porcelain crab, Pisidia longicornis, and tunicates (5 percent) with the species Phallusia mammillata
and Ascidia mentula. The main target species, Great Mediterranean scallop, was most abundant on
collector Type II, with 28 individuals. From three types of experimental collectors used in the process
of collecting larvae of shellfish and biofouling species, collector type-I and type-II proved to be a
more suitable basis for receiving larvae of shellfish due to the unimpeded flow of sea water that allows
their successful growth and development. Species Talochlamys multistriata, were found in great
abundance and it could be good candidate to diversify the aquaculture production, thus potentially
offering farmers an additional source of income.
