Abstract:
This study presents an analysis on the food diet of Batissa violacea – a threatened indigenous non-marine edible mollusk, in the largest river ecosystem in the Philippines. The B. violacea samples were collected along the Cagayan River using a dredging equipment locally known “Tako”. A 240 samples out from collected 1,510 B. violacea were dissected and food organisms were estimated using gut analysis. The food diet of B. violacea is composed of 80-90% detritus and 10-20% food items such as green algae (35.83%), diatoms (33.13%), euglenophyceae (3.22%) and cryptophyceae (1.94%). These food items could be acquired by the bivalves through suspension feeding and deposit feeding. To ensure success in fishery development on breeding and production of B. violacea to replenish natural stocks in Cagayan River and in the prospect of venturing to aquaculture production of B. violacea in the future, sufficient supply of these identified food items must be ensured.
