Short description Morphology | Morphometrics

Dorsal soft rays (total): 17-25; Anal soft rays: 10 - 22; Vertebrae: 57 - 65. Diagnosed from all other freshwater fishes in Europe by the combination of the following characters: long snout; large mouth; dorsal fin origin slightly in front of anal origin; and lateral line with 105-148 scales (Ref. 59043). Distinguished by its long, flat, 'duck-bill' snout; its large mouth with many large, sharp teeth; and the rearward position of its dorsal and anal fins (Ref. 27547). Gill rakers present only as patches of sharp teeth on gill arches; lateral line notched posteriorly (Ref. 27547). Dorsal located far to the rear; anal located under and arising a little behind dorsal; pectorals low on body, base under opercle; pelvic fins low on body; paired fins rounded, paddle-shaped (Ref. 27547). Caudal fin with 19 rays (Ref. 2196).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Spawners move inshore or upstream to the marsh areas to spawn (Ref. 27547). Generally, spawning occurs during the day. The sexes pair and a larger female is usually attended by one or two smaller males. They swim through and over the vegetation in water usually less than 17.8 cm, releasing eggs and sperm simultaneously at irregular intervals (Ref. 1998). Eggs are deposited in flooded areas and on submerged vegetation over a period of 2-5 days (Ref. 59043). Only 5 to 60 eggs ae released at a time (Ref. 27547). This act is repeated every few minutes for up to several hours, after which the fish rest for some time before resuming. During the resting period, both male and female may take new mates, or they may continue together for several days until all eggs are extruded. Spawned-out adults may stay on the spawning grounds for as long as 14 weeks, but most leave within 6 (Ref. 27547).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5157   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00395 - 0.00505), b=3.08 (3.04 - 3.12), in cm total length, based on LWR estimates for this species (Ref. 93245).
Trophic level (Ref. 69278):  4.1   ±0.4 se; based on diet studies.
Generation time: 6.8 (5.7 - 8.3) years. Estimated as median ln(3)/K based on 37 growth studies.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (K=0.07-0.3; tm=2-3; tmax=30; Fec=2,000-600,000).
Nutrients (Ref. 124155):  Calcium = 38.5 [17.1, 95.8] mg/100g ; Iron = 0.545 [0.256, 1.159] mg/100g ; Protein = 17.8 [15.8, 19.8] % ; Omega3 = 0.632 [0.302, 1.317] g/100g ; Selenium = 54.2 [15.4, 212.9] μg/100g ; VitaminA = 20.3 [6.2, 68.8] μg/100g ; Zinc = 1.56 [0.88, 3.02] mg/100g (wet weight); based on nutrient studies.
