Abstract

ABSTRACTThe Effect of Depth to Deposition Process on Round Nucleus of Fresh Water Mussel (Anodontawoodiana). One of the affecting factors to the quality of pearl culture is the thickness of pearldepositions (nacre). The objective of this study was to obtain information on best level ofdepth to culture of pearl, to get fast nacre deposition and high quality of pearl. The researchwas conducted for 9 months, in the freshwater pond, was 300 m2 wide and 1 m deep. Freshwaterpearl Anodonta woodiana, sized ranging from 12 – 15 cm were studied. Completely randomizeddesign was used with levels of deep treatment (A) 30 cm; (B) 60 cm and (C) 90 cm. The resultshowed that best thickness of pearl deposition by 90 cm deep (1.30 mm) but hasn’t biggestsignificant (P>0.05) to the deep of 60 cm (1.10 mm) and biggest significant (P< 0.05) to the deepof 30 cm (0.70 mm). The result of implantation was followed that 30, 60 and 90 cm deep were 11.9%; 12.2 %; 12.0 %, whereas survival rate was followed 79.2 %; 79 % and 78.7 %.Keywords: Freshwater mussel; Anodonta woodiana; effect; level of deepKata kunci: Kerang air tawar, Anodonta, woodiana, kedalaman laut

Abstract

Unionidae Shells have a potential economic importance for humans.  These shells can be used as commodity farming inland fisheries due to the their flesh can be eaten, have a protein content 7.37 grams in 100 grams of meat, the shell is useful for industrial raw material studs and animal feed, as well as this animals can be cultivated as a pearling. The purpose of this research is to know a good way where maintenance against the growth of Anodonta woodiana Pearly shells, Lea. materials in this research is the parent of mussels reared in freshwater pool with two different ways, first is hanged in koja (basket and second way is removed at the bottom of the pool. Monitoring the quality of the physics and chemistry of water is done every week i.e. parameters: temperature, pH, DO, NH3, calcium, debit and brightness. Identification of plankton swimming is done every week. Clam growth measured on a weekly basis: average weights, Ø length of the shell, the shell width, Ø and Ø thicker shell and survival. Average weight of shells and shell growth being maintained well with the observed two different ways during the 6 week look is always incremented even though relatively slow. Maintenance of basic dribbling off better against the survival and growth of diameter shells compared to how hung in various spices. Key words : Anodonta woodiana, Lea, was hanged in the basket, off base.
