Descrição breve Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 67 - 96; Espinhos anais: 0; Raios anais moles: 58 - 84; Vértebras: 50 - 67. Diagnosed from all other freshwater fishes in Europe by its pelvic fin origin anterior to pectoral fin origin and by having one central barbel on lower jaw (Ref. 59043). Distinguished by the long second dorsal fin, at least 6 times as long as the first, and a single barbel on the chin (Ref. 27547). Gill rakers short (Ref. 27547). First dorsal short; second dorsal and anal fins joined to caudal; pectorals short and rounded; caudal rounded (Ref. 27547), with 40 rays (Ref. 2196). Color is yellow, light tan to brown with a pattern of dark brown or black on the body, head and fins (Ref. 1371). Pelvic fins pale, others dark and mottled (Ref. 27547).
The only member of Lotidae family which lives in freshwater. Crepuscular and nocturnal (Ref. 11941). Adults are found in well oxygenated flowing waters and large, deep lakes as well as large rivers with slow-moving current (Ref. 5723, 10294). They occur from estuaries of large lowland rivers as well as from small mountain streams, preferring deep waters in summer (Ref. 59043). They seek shelter under rocks, in crevices on the river banks, among roots of trees and dense vegetation (Ref. 30578, 10294). Those in rivers tend to congregate in deep holes throughout the year, except at spawning (Ref. 27547). Movements into shallower water during summer nights are related to feeding (Ref. 1998). Smaller individuals feed on insect larvae, crayfish, mollusks and other invertebrates with a changing preference for fishes in larger individuals (Ref. 1998, 10294). In Central Europe, males mature at 2 years while females at 3 years (Ref. 59043). Spawning occurs from November to March, at temperatures below 6°C in groups of up to 20 interlaced individuals forming a ball about 60 cm in diameter which constantly moves and rolls on the bottom while releasing eggs and sperms (Ref. 59043). May undertake short spawning migrations (Ref. 59043). Eggs are semipelagic, 1.2-1.8 mm in diameter and slightly sticky hatching after 40-70 days (Ref. 59043). Larvae are positively phototactic, floating below the surface in March and April (Ref. 59043). Larvae feed on drifting invertebrates or zooplankton (Ref. 59043). Source of oil. Sold mainly salted. Liver is sold smoked or canned in Europe (Ref. 1998). Processed into fishmeal (Ref. 1998). Because of its nocturnal habits and its slow movements, this fish is not very much appreciated by sport fishermen. Flesh is tasty but a little dry (Ref. 30578). Locally threatened due to river regulation (Ref. 59043).
Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas
There appears to be individual movements into spawning areas with the males arriving first at spawning areas (Ref. 27547). It occurs at night, with spawners forming a great globular mass, each pushing toward the center (Ref. 28694), or at least milling around close together (Ref. 28697), releasing eggs or sperm. Observed to make postspawning runs upriver, apparently for feeding (Ref. 28697). Eggs hatch after 40-70 days. After about 2 months, juveniles are benthic, grow rapidly, reach about 8 cm SL within first year. (Ref. 59043).
