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); 43°N - 9°N, 79°W - 74°W (Ref. 57273)
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)
Western Central Atlantic: Massachusetts to Florida, throughout the Gulf of Mexico, to Panama.
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.
