| ข้อสังเกต | Found on the continental shelf and continental slope (Ref. 75154). Adult ocean perch are present in depths from 50 m to 750 m. Two forms of ocean perch are recognised in waters off New South Wales, Australia (Ref. 6390). They are referred to as 'inshore' and 'offshore' forms based on their preferred depth ranges (Ref. 6390). The inshore form is dominant in depths less than 300 m and the offshore form is most common in deeper waters (Ref. 30468). The morphology of ocean perch indicates that they feed by resting on the sea bed and ambushing their prey (Ref. 6390). |
