Abstract

The limiting factor which is a weakness of sea water pearl production are high costs, the risk of major business failures and a long coating time. From the issue of freshwater pearls appear to have prospects of alternative substitution for sea water pearl. This present study aimed to evaluate effect of loads (the number and diameter nucleus) on freshwater pearl coating process and the number and size of the appropriate nucleus diameter, to produce the optimum coating thickness of half-round pearls. The research consists of experimental implantation of 2, 4, and 6 nucleus number per individual mussel was maintained by the method stocked in hapa in bottom waters. Observation method and factorial randomized block design used in the study of the influence of the load to the successfulness of  pearl coating and the pearl layer thickness. The results showed that A. woodiana can be utilized as a producer of freshwater pearls. In addition, the number of optimum nucleus that can be attached to the mussel A. woodiana was 2 grains/individuals with a diameter of 10 mm. Shells implanted with the optimum nucleus diameter and number of pearls produced the highest layer thickness of 17 mm after 9 months cultivation. This result was good enough compared with the layer thickness of sea water pearl production after the same cultivation time.

Abstract

An experiment was conducted to study the effect of male and female host oysters on the pearl sac formation in Pinctada maxima oyster. One hundred sixty oysters were used in a completely randomized design with 2 x 4 factorial arrangement and 20 replications. The 1st factor was that sex of host oyster consisted of two levels that is males and females. The 2nd factor was week after nucleus implantation with four levels that is 1, 2, 3, and 4 weeks. The parameters observed were the percentage of successful oysters to form the pearl sac, the speed of pearl sac formation, the percentage of nucleus coverage by the pearl sac, histology of the pearl sac growth and development, and haemolymph glucose, calcium and phosphorus concentrations. Our results showed that the percentages of host oysters that succeeded in forming a pearl sac were 80% and 75% in female and male host oysters, respectively. There was no statistical difference in nucleus rejection and mortality in male and female host oysters but the results indicated that male host oysters showed a numerically higher nucleus rejection. The speed of pearl sac growth and the percentage of nucleus coverage by the pearl sac in female host oysters were better than those in male host oysters. Haemolymph calcium, phosphorus and glucose concentrations, oxygen consumption, and histological development of the pearl sac were not different between male and female host oysters. Pearl sac formation in the female host oysters was better than that in male host oysters.
