Kuala Sepetang's cockle farms a shell of their former selves


David ST Loh

COCKLE breeding is a multi-million-ringgit industry in Malaysia. At its peak in 2005, it produced 100,000 tonnes of the molluscs for local consumption and export.

Often found in char koay teow, curry noodles and “lok lok’“stalls, cockles add to the dish the flavour of the sea that some would describe as a metallic tang.

Kuala Sepetang was once the largest cockle-breeding grounds in Malaysia. Cockle farmers here used to earn RM5000 to RM6000 a month, harvesting up to more than 28,000 tonnes of cockles a year. These days, the harvest has dropped to less than 7,000 tonnes a year.

Many farmers have turned to other forms of aquaculture for fish and prawns, or ferrying tourists on their boats as eco-tourism grows in Kuala Sepetang.

Those who have stuck to cockle farming have to be contented with smaller yields. Some have resorted to harvesting the bivalves early, while they are the size of a five sen coin even though they fetch better prices when they have reached the size of a 50 sen coin or larger.

Pollutants in the water believed to be from discharge of raw sewage, aquaculture and open rubbish dumps are some of the main causes of the dwindling harvests. There is also fear of Hepatitis A contamination.

Regular monitoring of the water quality in the cockle farms is essential for the production of healthy, adult cockles. – September 30, 2018.
