Actinopterygii (ray-finned fishes) > Pleuronectiformes
(Flatfishes) > Achiridae
Etymology: Trinectes: Greek, tres, tria, = three + Greek, nekton = swimmer (Ref. 45335).
Environment / Climate / Range
Marine; freshwater; brackish; demersal; amphidromous (Ref. 40808); depth range 0 - 75 m (Ref. 57178), usually 50 - 60 m (Ref. 51483). Subtropical; 5°C - 22°C (Ref. 13614), preferred ?; 43°N - 9°N, 79°W - 74°W (Ref. 57273)
Western Central Atlantic: Massachusetts to Florida, throughout the Gulf of Mexico, to Panama.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 20.0 cm TL male/unsexed; (Ref. 7251); common length : 11.0 cm TL male/unsexed; (Ref. 12193); max. reported age: 7 years (Ref. 51483)
Adults inhabit coastal waters. They also enter fresh waters, going hundreds of miles upstream. Migrate downstream to spawn in spring (Ref. 36739). Larvae move upstream after hatching (Ref. 36739). Minimum depth reported taken from Ref. 57178.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00716 - 0.02213), b=3.09 (2.93 - 3.25), based on LWR estimates for this species & (Sub)family-body (Ref. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=1; tmax=7; K=0.21(?)).
Prior r = 0.81, 2 SD range = 0.51 - 1.27, log(r) = -0.21, SD log(r) = 0.23, Based on: 1 K, 3 tgen, 1 tmax, records
Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100) .
