How to improve carrying capacity of cockle in earthen ponds at the Upper Gulf of Thailand

This study aims to investigate cockle density in an earthen pond. And examined the role of seaweed (Gracilaria and Caulerpa) for oxygen producers as phytoplankton and treatment waste from cockle metabolism.  The density of cockles was calculated from water quality, net production of phytoplankton, net oxygen production of seaweed, and feeding behavior of cockles. After that, the density of the cockle was rearing in a mesocosm. Rearing of cockle has done in 3 seasons, represented summer, rainy and winter. The results from mesocosm are analyzed with survey data from the local farmers. To investigate the investment and management application for creating a guideline for cockle culture development.
