Length at first maturity / Size / Peso / Age

Maturity: L_m 32.5, range 30 - 35 cm
Max length : 50.0 cm TL maschio/sesso non determinato; (Ref. 27368)

Lacustrine, pelagic, usually at 0-40 m during summer. Feeds on plankton and insects; preys on juvenile Perca fluviatilis in summer. Spawns at surface over deep water, off-shore. Spawns for the first time at 2-3 years and in first half of December, when temperature falls below 7˚C. Males aggregate at surface and females ready to spawn come from deeper water to join these aggregations. Eggs sink to bottom and hatch in March. Larvae swim to surface and start to feed after 8 days (Ref. 59043). Also Ref. 13813, 47057.

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00457 (0.00190 - 0.01097), b=3.13 (2.92 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.30 se; based on food items.

Generation time: 7.8 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (tm=2-3).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).

Price category (Ref. 80766): Very high.
