Actinopteri (ray-finned fishes) > Scombriformes
(Mackerels) > Arripidae
Etymology: Arripis: Latin, arripio, arripere = to take something suddenly. More on author: Forster.
Environment: milieu / climate zone / depth range / distribution range
Marine; brackish; pelagic-neritic; anadromous (Ref. 51243); depth range 30 - 39 m (Ref. 58489). Subtropical; 27°S - 47°S, 112°E - 176°W
Southwest Pacific: southern Australia (including Tasmania, Lord Howe Island and Norfolk Island), usually Brisbane to Western Victoria, rarely to Western Australia; and New Zealand (including Chatham and Kermadec Islands).
Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 29 - 36 cm
Max length : 89.0 cm TL male/unsexed; (Ref. 27296); common length : 47.0 cm TL male/unsexed; (Ref. 9258); max. published weight: 9.4 kg (Ref. 9988); max. reported age: 26 years (Ref. 9072)
soft rays: 9 - 10;
Vertebrae: 25. Adults are dark blue-green above and silvery below, with irregularly defined spots arranged laterally in indistinct rows (Ref. 33616). Length of upper lobe of caudal fin < 29.9% SL, more or less equal to, or less than, the length fo the head (Ref. 9701).
Inhabit continental shelf waters including estuaries, bays and inlets (Ref. 6390). Found between depths of 30 m (Ref. 33616) and 39 m (Ref. 58489). They enter rivers (Ref. 9002). Juveniles form school in shallow coastal bays and estuaries; adults move in large schools along shores (Ref. 9002), and can move over reefs in depths just sufficient to cover their bodies (Ref. 6390). They form large surface aggregations in deep water (Ref. 6390). Feed mainly on fishes but also on pelagic crustaceans, especially krill (Nyctiphanes australis). Take also food from the seabed. Fish smaller than 10 cm feed predominantly on copepods (Ref. 9072). Utilized fresh, canned and frozen; can be steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988).
Eastern Australian salmon are probably serial batch spawners (Ref. 27961).
