Karantina Island to find pearl oyster ( <i>Pinctada
radiata </i> Leach, 1814) spat collection efficiency of bag and shell collector
types. Environmental limits such as temperature, salinity, chlorophyll-a, and
total particulate matter (TPM) were monitored during the study period. The
abundance of <i>P.radiata </i> spat were
found on the bag collector as 11.66±2.08 ind./0.91m <sup>2 </sup> at the first
time in August. At the same month the highest temperature and salinity were
recorded as 27 ºC and 36.5‰, respectively. G2 (group 2/deployed on June 25)
performed the highest spat collection for the bag collectors while G4 (deployed
on August 29) for the shell collector was more successful during the research.
A total of 172±34.39 <i>P. radiata </i> spat
were collected during the study. 119±22.60 (69.18%) individuals (ind) were
harvested from bag collector and 53±11.78 (30.82%) from shell collector. While
the avarege abundance of <i>P. radiata </i>
spat were 7.26 ind./m <sup>2 </sup> on bag collectors, it was 3.23 ind./m <sup>2 </sup>
on the shell collectors. A significant difference was determined in the total
abundance of <i>P. radiata </i> between the
collector groups (p<0.05). The length range of Pinctada spat on the bag
collectors was between 4.47- 33.9 mm while it was 4.66-18 mm on the shell
collectors. Fouling organisms (barnacles, polychaete, bryozoa) and predators
(crabs, gastropods) of pearl oyster were also found on the collector groups.
Results of the study established that bag collectors were more effective to
collect the pearl oyster spat than the shell collectors. </span> </p> <p> </p> </div> </div>}, number={2}
