Males reproduce at 2-3 years and females at 3-7 years. Spawning happens, depending on latitude, between May and September, at temperatures of 19 20°C. Lays numerous sticky green eggs on plants or on the botton every 1 5 days for 2 months. Incubation at 20°C lasts 3 days. Larvae remain attached to the plants for several days until the vitellus is used up. Egg size 0.8-1.0 mm, larval length at hatching 4-5 mm.
Maximum size: 840 mm TL
In Europe spawning occurs from May-August; in eastern U.S., spawns from late May through the third week in June. Females lay about 500,000 eggs per kg of body weight. Eggs hatch in 6-8 days (Moyle 1976). Sexually mature in 3rd or 4th year. May live up to 20-30 years.

Body thickset, heavy, and laterally compressed, the caudal peduncle characteristically deep and short. Skin thickened, slimy; the scales small, embedded. Overall coloration olive-green, at times dark green or almost black, with golden reflections on ventral surface. Head triangular, eye orange-red, small; snout relatively long; interorbital broad; mouth terminal, small in size with thick lips and a pair of well-developed barbels, one at each corner of the mouth. Caudal fin with 19 rays (Ref. 2196). Diagnosed from other cyprinid species in Europe by the following characters: body golden greenish brown; one pair of barbel (maxillary); lateral line with 96-115 scales, small and deeply embedded; dorsal fin with 8-9½ branched rays; and anal fin with 6-9½ branched rays (Ref. 59043).

Tench have a dark green to black back and a bronze-colored belly. The fish has a high back, small scales and extremely slimy skin. Using its barbels to feel the bottom, it searches for food primarily at night. Its eyes do not play a major role and therefore are small. Tench eat small snails, water fleas, crustaceans and mosquito larvae. They also eat parts of plants, algae and detritus.

Habitat and Ecology
Typically in shallow, densely vegetated lakes and backwaters. Often overwinters buried in mud. Spawns among dense vegetation in still water.
Biology:
Lives up to 20 years. Spawns for the first time at 2-6 years and 70-250 mm SL, females a year later than males. Pelvic rays more robust, longer and extending beyond anus in male. Spawns in May-October, in Central Europe usually in June-July, at temperatures above 19C, mostly at 22-24C. Several males follow each female, which releases eggs in several portions above vegetation. Females may spawn 1-9 times each year, every 11-15 days, if suitably warm weather persists. High embryonic mortality observed when temperature fluctuates strongly. Larvae and juveniles restricted to dense vegetation. Tolerant of low oxygen concentrations and salinities up to 12 . Feeds on detritus, benthic animals and plant material. Adults often feed predominantly on molluscs.
