| Summary: | C. fluminea is a very popular traditional food for local community in Kelantan. Therefore, raw C. fluminea demand in local market is high. However, the sources of this raw clam is keep decreasing due to changes of their habitat and unsustainable harvesting. Therefore, this study is aim to determine the correlation of the organic matter at study area with the age and size of C. fluminea. C. fluminea and sediment samples collected at two stations with three lines per station by using harvesting tools and plastic bucket. The age of C. fluminea identified by calculating its annual rings and Caliper digital used to measure the height and width size of C. fluminea. Next, loss on ignition (LOl) analysis used to determine the concentration of organic matter in the sediment samples. The table used to represent the correlation between size and organic matter. Results shows, the composition of C. fluminae at all stations show the high collection during May till July with range width and length size is between 13 mm — 20 mm. 99% of C. fluminea collected was with age 4 years. Therefore, no correlation with the organic matter found. Based on line graph, a parallel pattern of size and organic matter at all station and line represent the positive correlated between the content of organic matter with the size of C. fluminea. This shows that the organic matter sediment might be one of factors that can influence the growth of Cfluminae. Therefore, it's recommended to harvest the C. fluminae after August to reach size 20mm which suitable size for harvesting and commercialize. Besides that, the organic matter content range from 0.1% to 50% is enough for the growth of C. fluminae. A plan and guideline of sustainable harvesting and organic matter control can be plan to ensure the sustainable supply of Cifiuminae in Kelantan. |
