生物学特性     字汇 (例如 epibenthic)

An active, gregarious fish occurring inshore and offshore waters. Usually enters coastal waters in spring and returns to deeper waters in winter (Ref. 9988). Smaller fish in inshore waters feed on small crustaceans (copepods, amphipods, euphausiids) and small fish, while larger fish prey predominantly upon fishes. Spawn in batches (Ref. 51846). Utilized fresh, dried or salted, smoked, canned and frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
