Abstract

The main problem on freshwater mussel culture is the high mortality during implantation process. Freshwater mussel that will be implanted for cultivation need to be conditioned in a state that facilitates the opening of its shell. Because lack of information on the use of anesthesia in the cultivation of freshwater mussel, these principles can be applied is the principle which has been successfully applied in the cultivation of sea mussel. This study aims to determine the best responses to materials anesthetic and dose in precondition of Anodonta woodiana which held in Freshwater Aquaculture Center (BBAT) Tatelu in District Dimembe, Minahasa Regency. The study was designed by using completely randomized design factorial pattern with two factors: materials anesthetic and dose. Material anesthetic factor has 4 degree such as menthol oil, clove oil, nutmeg oiland lemongrass oil. Dose has 3 degree such as 1,5 ml, 2,5 ml and 3,5 ml. Each treatment was repeated 3 times. The results showed that nutmeg oildose of2,5 ml/L more effective for precondition (respons, relaxation time, recovery and mortality rate) than dose of 1,5 ml/l and 3,5 ml/L and than another materials anasthethic (menthol oil, clove oil, and lemongrass oil).

Abstract

The pearl oyster Pinctada margaritifera (Linnaeus, 1758) or black lip pearl oyster is a marinebivalves with important economic value. This Indo-Pacific species is found in abundance in the waters of North Sulawesi, but cultivation activities have not been optimized. Growth information is important for aquaculture activities because it is a useful indicator to determine the health of pearl oysters and environmental suitability (Moussa, 2013). The purpose of this study was to determine the growth pattern of P. margaritifera pearl shells in the waters of North Sulawesi. Species P. margaritifera were collected at a depth of 2-20 m in the waters of North Minahasa Bahoi, Arakan waters South Minahasa and Talengen waters Sangihe Islands, North Sulawesi Province. The morphometric parameters observed included shell length (PC), shell height (TC), shell thickness (tC), and total weight (BT). The relationship between length, height, shell thickness and total weight was analyzed by regression equation. Morphometric measurements of P. margaritifera showed average shell length (PC) of 95.26 mm (Arakan waters), 81.15 mm (Talengen waters) and 70.19 mm (Bahoi waters). The growth pattern of P. margaritifera in the waters of Bahoi, Arakan and Talengen, North Sulawesi Province was allometric negative. This means that the increase in length, height and thickness of the shell is faster than the total weight.
