Causes and Management of Mass Mortality for Green Mussel

One of the causes of low mussel production is the low survival rate of the cultured mussels. Occurrence of these mass mortalities were observed in nine mussel producing provinces, Cavite, Bataan, Pangasinan, Sorsogon, Aklan, Capiz, Negros Occidetal, Samar, and Davao. Identifying the causes of these mass mortalities and developing of remedial measures to address this problem will contribute to the high production and sustainability of the mussel industry.

This project aims to study the possible cause of the die-off syndrome and mass mortalities in mussel sites and find remedial measures to address these problems and develop a management strategy to reduce/minimize mortalities. This project was based on the initial findings of Project 1&2 of this program. Geospatial Information System (GIS)-based maps were generated showing the location of existing mussel farms and the areas where mass mortalities occurred. Physiological laboratory experiments were also being conducted to research for possible factors for occurrence of mass mortalities.
