Abstract

Oysters belong to the bivalve class, which has a soft body and is protected by two hard shells. Living in groups and sticking together on various substrates. Oysters have high nutritional content so that the need for oysters continues to increase unbalanced with the availability of oysters in the habitat. The study aimed to see the pattern of growth of various culture media of oysters. The research was carried out from May until June 2019. Samples were taken in three water areas based on cultivation media with a purposive sampling technique when the water receded, and data analysis was carried out in the Laboratory. Oysters from cultivation media showed the growth pattern (b = 0.47 to 0.65) with a coefficient of determination (R2 = 0.25 to 0.83) while oysters without cultivation media showed growth pattern (b = 0.44 to 0.51) with the coefficient of determination (R2 = 0.19 to 0.27) and all show allometric negative growth patterns (b <3). The results of the value of b and the coefficient of determination obtained in the culture media are greater than the values obtained without the cultivation media, which shows that the use of cultivation media is very effective in oyster production.
