Silver Warehou, Seriolella punctata (Forster 1801)

More Info


Distribution

Off Port Stephens, New South Wales, to the Gulf St Vincent, South Australia, and off Tasmania. Elsewhere the species occurs in New Zealand, the western Atlantic, southeastern Pacific and subantarctic islands.
Adults are bethopelagic in deeper offshore water to a depth of 650 m. Small juveniles are pelagic. As the grow, older juveniles move inshore and may be found in bays and inlets. 

Features

Dorsal fin VII-IX, 35-39; Anal fin III, 21-24; Caudal fin 17; Pectoral fin 19-22; Pelvic fin I, 5; Lateral line scales ~110-120; Gill rakers 5-7 + 1 + 14; Vertebrae 25.
Body streamlined, moderately shallow (27-33% SL), compressed; caudal peduncle slender, without lateral keels. Head of moderate size (26-31% SL); snout pointed; eyes small (14-23% HL); mouth small, maxillae reaching below front of eyes, slightly oblique; teeth fine, single row in each jaw. Pyloric caeca few and finger like. 
Scales very small and easily dislodged, anterior scale limits on nape with distinct fleshy margin forming pointed 'mask'; lateral line curved, about parallel to profile of back. Head and trunk covered with numerous small pores.  
Two dorsal fins, first dorsal with origin above pectoral fin bases, having short stout spines, connected by membrane to base of second dorsal, second dorsal fin much higher, anterior fin rays longest, outer margin deeply concave; anal fin similar to and opposite second dorsal; caudal fin deeply forked. Pectoral fins of moderate size, not reaching to anus, moderately falcate. Pelvic fins of moderate size, thoracic.

Colour

Silvery blue to grey on back, almost metallic, paling somewhat on sides, silvery white on belly; head darker grey brown above and around snout and around eyes, creating a 'mask'; dark blotch above each pectoral fin base, followed in small examples by irregular lateral series of small dark spots which are lost in large individuals.

Feeding

Feeds mostly on pelagic invertebrates such as pyrosomes and other tunicates.

Biology

A schooling species that forms aggregations near the seafloor to feed and spawn. Individuals mature at about 4 years of age, and spawn during late winter to early spring. Females produce up to about 1.6 million eggs per spawning season.

Remarks

A valuable food fish mostly taken by trawl, although some non-trawl (gillnet) catches occur.
