Clupeiformes (Herrings) >
Ehiravidae (River sprats)
Etymology: Clupeoides: Latin, clupea = sardine, derived from Clupeus = shield; + Greek, oides = similar (Ref. 45335).
More on authors: Weber & deBeaufort.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Freshwater; pelagic. Tropical; 5°S - 8°S
Asia and Oceania: Indonesia (Lorentz River, Irian Jaya) and Papua New Guinea (Fly River); probably in other southwest-flowing rivers in area.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm SL male/unsexed; (Ref. 2847)
Dorsal spines (total): 0; Dorsal soft rays (total): 12 - 18; Anal spines: 0; Anal soft rays: 16 - 27. Body moderately deep, belly sharply keeled, with 9 to 12 + 7 to 9 scutes. Snout blunt, pre-maxillae short and toothless, but prominent teeth in lower jaw; second supra-maxilla short, a little over half length of maxilla blade. Pectoral axillary scale small, less than 1/3 length of fin. A silver stripe along flank.
The only clupeid in the world known to inhabit mountainous rivers (Ref. 2847). Occurs in streams with gravel or stony bottoms and feeds primarily on aquatic insect larvae (Ref. 2847).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00871 (0.00366 - 0.02072), b=3.03 (2.83 - 3.23), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.2 ±0.40 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
