Ghi chú mồi

Use large live or cut fish, chunk bait, shrimp, worms, and oily dead bait; oversized soft plastics and swimbaits can also draw strikes. Match local prey and fish big baits to target large individuals.

Hành vi

Primarily nocturnal and crepuscular, with a strong sense of smell and lateral-line detection. It is an opportunistic predator/scavenger that patrols deep water and ambushes prey along drop-offs and cover.

Thận trọng

Strongly advised not to release outside native range because it is an invasive risk in many waters. Large individuals may accumulate mercury; also handle with care due to sharp pectoral spines and powerful body mass.
