Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

पृष्ठीय रीढ़ (सम्पूर्ण) : 9 - 10; पृष्ठीय सौफट रेज़ (सम्पूर्ण) : 8 - 11; गुदा कांटा: 3; ऐनल सौफट रेज़: 7 - 9; जानवरों की रीड़ का जोड़: 25. Dark gray on back, becoming paler below with overall silvery sheen; lower sides and belly whitish; fins dusky brown to dark brown, darker distally (except pecorals).

An estuary-dependent catadromous fish inhabiting the tidal reaches of rivers, lakes and coastal lagoons where it is found (Ref. 7300, 123463); with salinities less than 1-2 ppt (Ref. 5259). Popular angling species that tends to swim near the bottom in deeper water. Feeds on small fishes, molluscs, worms, shrimps and other crustaceans. During winter (July and August) they move to the mouth of estuaries to breed (Ref. 44894). Individuals are long lived, reaching to more than 40 years (Ref. 123463). Oviparous, egg is pelagic (Ref. 5259) and hatches in 2-3 days. Male reaches maturity at a length of about 22 centimeters; female at about 28 centimeters (Ref. 44894).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01096 (0.00423 - 0.02842), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.5 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): बहुत नीचे, न्यूनतम जनसंख्या दुगनी समय अवलागत 14 महीने। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

Price category (Ref. 80766): Unknown.
