Short description Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία

Ραχιαίες άκανθες (συνολικά) : 8 - 9; Μαλακές ραχιαίες ακτίνες (συνολικά) : 10; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 6. 67- to 72 pored scales on lateral line to base of caudal fin (Ref. 26938). Black lateral line (Ref. 13442).

Adults inhabit coastal waters, estuaries and lagoons, penetrating into freshwater; usually at depths less than 20 m (Ref. 3713). Feed on fishes (Gobiidae, Gerreidae, Engraulidae) and crustaceans (shrimps and crabs) (Ref. 35237). Mature individuals congregate at mouths of passes and rivers during the spawning season, May through September (Ref. 3713). Seasonal movements into freshwater occur but poorly understood (Ref. 3713). Marketed fresh (Ref. 5712). Valued game fish and an excellent food fish (Ref. 26938). The world record for hook and line is a 53-lb., 10 ounce fish caught at Parismina Ranch, Costa Rica (Ref. 13442).

Estimates based on models

Preferred temperature (Ref. 115969): 23.5 - 28.1, mean 27.3 (based on 864 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00741 (0.00587 - 0.00936), b=3.02 (2.97 - 3.07), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Τροφικό Επίπεδο (Ref. 69278): 4.2 ±0.6 se; based on diet studies.

Ελαστικότητα (Ref. 120179): Μεσαίο(α), ελάχιστος χρόνος για διπλασιασμό πληθυσμού 1,4 - 4,4 έτη (K=0.3-0.49; tm=4; tmax=7; Fec=3 million).

Prior r = 0.87, 95% CL = 0.58 - 1.31, Based on 2 data-limited stock assessments.
