Ehrenberg’s snapperLWE

 
Lutjanus ehrenbergii
20.7 cm TL

Characteristic features:

  • Longitudinal scale rows above lateral line mostly horizontal
  • Vomerine tooth patch with posterior extension
  • Preorbital space narrow (9–10 times head length)

Colour:

4 or 5 narrow yellow stripes on sides, large round black spot below posterior dorsal fin over lateral line.

Size:

Up to 35 cm TL.

Distribution:

Indo West Pacific in tropical waters.

Habitat:

Coral reefs, often near fresh water run-offs, from 1 to at least 20 m depth.

Biology:

Feeds on small fishes and crustaceans when juvenile, and predominantly crustaceans when adult.1 Often forms large schools. Females attain a larger size than males. In the waters of the Arabian Gulf first maturity is reached at a size of 20.4 and 19.9 cm FL for females and males respectively, corresponding to 1.8 and 1.7 years for females and males, respectively.2 In the Arabian Gulf, Ehrenberg’s snapper has a single spawning season occurring between March and June. Estimated maximum age is 12 years.2

Fisheries:

Caught mainly with handlines, traps and gill nets.
