![]() The national spat collection program will generate significant livelihood benefits across Fiji and support continued expansion of the Fijian cultured pearl industry. The aim of this task is to potentially identify a way to develop more efficient spat collecting techniques that may compensate for the lower survival rate. Results identified sites supporting high levels of pearl oyster recruitment as a basis for an ongoing national spat collection program, and support better targeting of spat collection activities that maximise oyster supply to the Fijian pearl industry. Results of this research indicate that wild oyster spat collection is a viable option in the initiation of an oyster industry in Georgia and that growers should. margaritifera based on greater levels of recruitment at these sites. Oysters began to grow after February and achieved a final weight of 21.7 g in May, with an average growth rate of 0.128 g/day (Figure 3). penguin have greater tolerance of more turbid inshore sites than P. Oyster weight did not increase significantly between October and February, varying between 9.9 and 10 g (P > 0.05). penguin ranged from 7.53 cm to 13.62 cm across sites. penguin were collected from all sites, with the highest number of recruits (495) recorded from Namarai (Viti Levu). margaritifera recruitment during the study and these were generally sites with relatively turbid water. kept feces and pseudofeces from collecting around the individual oysters. Oyster spat attaches to cementable or non cemented collector and grows into to oyster seed. margaritifera at any site was 8.61 ± 0.30 cm while the smallest was 4.26 ± 0.13 cm. Coupelle Collector method for oyster seed collection. The largest mean dorso-ventral measurement (DVM) of P. margaritifera juveniles were collected from all sites with the highest number of recruits (693) and the highest number of recruits per collector (2.10 ± 0.17) occurring at Nacobau (Vanua Levu). Spat collectors were deployed for a period of 10–15 months when the number of pearl oyster ( Pinctada margaritifera and Pteria penguin) spat attached to each collector was counted and shell size recorded. Spat collectors consisted of a 100 m longline from which 310 individual spat collectors were suspended. Twenty-nine sites across Fiji were used in this study. This will avoid deployment of spat collec tors that will only gather barnacles. ![]() Fifty spat attachments on each shell collector signals the correct time to deploy spat collectors. Manually, the tray is placed on a metal frame and struck hard with a stick. But spat collectors may also be de ployed to monitor the amount of spats. How it is used / deployed: The trays are piled 3 to 5 high, according to the height of the tide, spat removal is either manual or automatic. This supply can be inconsistent and a research program was implemented to determine recruitment of pearl oysters to spat collectors at sites throughout Fiji as a basis for developing a national spat collection program to improve reliability of oyster supply to the industry. Oyster spat collection, usually on tidal flats. Cultured pearl farming in Fiji relies on wild spat collection to supply the oysters used for pearl production.
