Etelis carbunculus


Pacific ruby snapper ETA
Characteristic features:

 

Colour:

Pinkish to reddish.

Size:

Up to 120 cm TL.

Distribution:

West and Central Pacific in tropical waters.

Habitat:

Rocky bottoms, from 90 to 400 m depth.

Biology:

Feeds primarily on fishes, larger invertebrates such as squids, shrimps and crabs, also feeds on planktonic organisms. A demersal species occurring in aggregations. Length at maturity estimates vary, in waters off Papua New Guinea, length at first maturity was 61.0 cm FL,1 while off Hawaii first maturity was recorded at 35 cm.2 In Vanuatu, spawning occurs throughout the year peaking in November.3 The mean published literature for longevity is estimated at 15.2 years.4

Indonesian fisheries:

Caught mainly with bottom longlines and deep handlines.
