Issue
Issue on validity of subspecies: the subspecies Hemiramphus convexus bruuni is elevated at species rank as Hemiramphus bruuni (Parin, Collette & Shcherbachev, 1980) in Eschmeyer (CofF ver. May 2011: Ref. 86870). The species page will be created.

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; pelagic-neritic; depth range 0 - 6 m (Ref. 86942). Tropical

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: widespread in warmer waters from East Africa to Caroline Islands, New Guinea, New Britain and New Ireland. Replaced in the Red Sea, Arabian Sea and coastal waters in between by Oxyporhamphus convexus bruuni (Ref. 9843).

Length at first maturity / Size / Weight / Age

Maturity: Lm ?, range 14 - ? cm
Max length : 23.0 cm TL male/unsexed; (Ref. 10943); 17.6 cm SL (female)

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 15; Anal spines: 0; Anal soft rays: 14 - 16; Vertebrae: 48 - 51. Swim bladder composed of many small compartments instead of a single chamber. Gill rakers on the first arch, 26-33, usually 27-31.

Biology     Glossary (e.g. epibenthic)

More coastal than O. m. micropterus and frequently found near islands.

Estimates based on models

Preferred temperature (Ref. 123201): 25.3 - 29.3, mean 28.7 °C (based on 2285 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5005   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00437 (0.00193 - 0.00988), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Generation time: 0.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (K>1).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
Price category (Ref. 80766):   Unknown.
