Abstract

This research was conducted in November 2018 to February 2019 in the sub-watershed of Lahombuti River, Lahotutu Village, Konawe Regency. The aim of the study was to determine the population abundance and distribution pattern of mussel (C. javanica) in the sub watershed of Lahombuti tributary, Lahotutu Village, Wonggedu Sub-District, Konawe District.

Sampling site was determined with purposive random sampling method. Sampling of mussel (C. javanica) was carried out in a location with the greatest abundance of mussel, that was insub watershed of Lahombuti tributary, Lahotutu Village, on the main rice field irrigation channel (width: ± 1.75 m, Length: ± 4500 m ( 4.5 km), Depth: ± 110 cm). Sampling of mussel was carried out at the same station with different sampling spot. Three quadratic transects sizing 1x1 m2 each were randomly assigned in the plots. The results showed that the highest abundance of mussel (C. javanica) was recorded in November with a value of 65.33 ind/m2 and the lowest population abundance was in February with a valueof 12.67 ind/m2.In other words, the abundance of mussel in the sub watershed of Lahombuti tributaries range from 12.67 ind/m2-65.33 ind/m2. In general, the results of population abundance analysis showed that the level of abundance was very high. The results of Morishita index analysis generally showed that distribution pattern of mussel (C. javanica) in the sub watershed of Lahombuti tributaries was classified as uniform pattern (Id <1). The results of this study indicate the potential availability of mussel resources (C. javanica) based on abundance data and distribution patterns in the Lahombuti River, Wonggeduku District, Konawe Regency.
