Lives generally at shallow depths near the shores on rocky bottom with aquatic vegetation to 60 m depth. Feeds on fish, crustaceans, worms and algae. Sold fresh in markets, also made into fish meal (Ref. 1371). Caught as a by-catch by various fishing gears (Ref. 35388).
通常以對 60 公尺深的水生植物住在岩石的底部上的海岸附近的深度淺的地方。 吃魚，甲殼動物，蠕蟲與藻類。 生鮮販賣在市場中了, 也製成魚粉.(參考文獻 1371) 捕捉作為一個各種不同漁網的誤捕.(參考文獻 35388)
