Preliminary results of spat collection of Rayed pearl oyster (Pinctada radiata) in Turkey

Abstract

This research was carried out in Karantina Island to find pearl oyster (Pinctada radiata 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 P.radiata spat were found on the bag collector as 11.66±2.08 ind./0.91m2 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 P. radiata 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 P. radiata spat were 7.26 ind./m2 on bag collectors, it was 3.23 ind./m2 on the shell collectors. A significant difference was determined in the total abundance of P. radiata 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.
