Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 0; Rückenflossenweichstrahlen (insgesamt) : 13 - 21; Afterflossenstacheln: 0; Afterflossenweichstrahlen: 12 - 23. Body moderately slender; head long and narrow; belly sharply keeled, with 26 to 32 scutes; pectoral fin tips rounded; last two anal fin rays enlarged; pterotic bulla absent; no notch at the center of the upper jaw.

Schools in the open sea, not approaching shores. Occurs mainly in the south in winter, migrating to the middle parts of the sea in spring and returning south in November-December. Found in upper layers in March-April, but descends to 16 to 32 m in summer and autumn. Feeds mainly on copepods, also pelagic mysids and small fishes. Breeds in January-September intermittently in the open sea. Stocks said to be depleted in southern part of Caspian Sea.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00445 - 0.01234), b=3.01 (2.87 - 3.15), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Generation time: 2.6 (2.2 - 4.1) years. Estimated as median ln(3)/K based on 11 growth studies.

Widerstandsfähigkeit (Ref. 120179): mittel, Verdopplung der Population dauert 1,4 - 4,4 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (26 of 100).

Preiskategorie (Ref. 80766): Low.
