The Influence of Different Culture Methods on the Growth and Survival of Kijing Mussels (Anadonta woodiana)

This study aimed to analyze the influence of different culture methods and stocking density on the growth and survival of Kijing mussels (Anadonta woodiana). This research employed an experimental method with a factorial Randomized Block Design (RBD), consisting of two factors: culture method (B) with two levels (bottom and floating) and stocking density (P) with three levels (5, 10, and 15 individuals). Each treatment combination of culture method and stocking density was conducted in triplicate concrete ponds. The homogeneity of the ponds could not be guaranteed due to the inconsistent sunlight exposure across the land conditions. The total number of treatment units used in this study was 18 treatment units. The parameters measured were absolute weight, absolute length, specific growth rate, survival rate, and water quality. Data on absolute weight, absolute length, and specific growth rate were analyzed using Analysis of Variance (ANOVA) with a 95% confidence level via SPSS software to determine treatment effects, followed by Duncan’s multiple range test. Meanwhile, data on survival rate and water quality were analyzed using Microsoft Excel. The results showed that different culture methods significantly influenced the absolute weight of Kijing mussels (A. woodiana) during the 60-day rearing period, whereas stocking density and the interaction between stocking density and culture method did not significantly affect any of the measured parameters. The bottom culture method resulted in better growth of Kijing mussels compared to the floating method, increasing the absolute weight of mussels by 106.38 g, supported by an absolute length of 3.20 cm, a specific growth rate of 2.17%/day, and a 100% survival rate.
