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=0.01175 (0.00793 - 0.01740), b=2.97 (2.89 - 3.05), in cm total length, based on LWR estimates for this species (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 3.0 ±0.41 se; based on food items.

Generation time: 2.8 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Ελαστικότητα (Ref. 120179): Μεσαίο(α), ελάχιστος χρόνος για διπλασιασμό πληθυσμού 1,4 - 4,4 έτη (tmax=10).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100).
