Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0. Body elongated; head small; eyes relatively small. Pelvic fins with a slightly elongated filament. Olive green brown or yellow dorsally, paler ventrally; with dark mottling on sides and fins.

Found in coastal, brackish and fresh water, landlocked in several lakes. Feeds mostly on small crustaceans, (especially shrimps and amphipods); also worms, small mollusks, squids and fishes (smelt, sticklebacks, striped bass, alewives, shed, herring and sculpins (Ref. 5951)) (Ref. 1371).

Estimates based on models

Preferred temperature (Ref. 115969): 2.7 - 12.6, mean 6.4 (based on 144 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00398 (0.00186 - 0.00854), b=3.13 (2.94 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.50 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (28 of 100).

Climate Vulnerability (Ref. 125649): High to very high vulnerability (75 of 100).

Price category (Ref. 80766): Low.
