Species Development state Trait Primary Data Secondary Data
Blicca bjoerkna Spawning conditions Spawning substrate Spawn amongst dense beds of submerged macrophytes No category
Cyprinus carpio Egg Oocyte diameter Unfertilized eggs are about 1-1.7 mm, and average 1.2-1.4 mm 1.35 mm
Cyprinus carpio Egg Egg adhesiveness Carp eggs are adhesive in water and stick to plants Adhesive
Cyprinus carpio Egg Incubation time At 20°C carp eggs hatch after approximatively 3.5 days 20.0 days
Cyprinus carpio Egg Degree-days for incubation In carp, the time between egg-fertilisation and hatching ranges from 60-80 degree days 70.0 °C * day
Cyprinus carpio Larvae Larvae behaviour After hatching, carp larvae a cement attach themselves to surface vegetation via cement glands on their head. They remain attached for 4-5 days while yolk is absorbed from a large yolk-sac and undergo organogenesis and other development Demersal
Cyprinus carpio Larvae Onset of exogeneous feeding Exogenous feeding begins before the exhaustion of yolk and is marked by the taking of air to fill the swim-bladder No data
Cyprinus carpio Female Age at sexual maturity In Victoria, males and females mature at 1 and 2 years of age. In tropical climates, carp mature at 3-6 months. In temperate-mediterranean climates, the age-at-maturity varies between 1 and 5 years. 4.5 year
Cyprinus carpio Female Female sexual dimorphism For female carp, they include the softening and enlargement of the abdomen and the reddening and protrusion of the cloaca Present
Cyprinus carpio Female Relative fecundity Estimates of instantaneous fecundity (the average number of strippd eggs per kilogram of fish) ranged from 114,000 to 163,000 eggs per kg 114.0 thousand eggs/kg
Cyprinus carpio Female Absolute fecundity The females are highly fecund and depending on body size, produce between 500,000 and 3 million eggs per spawning 500.0 thousand eggs
Cyprinus carpio Female Maximum GSI value Recorded estimates are usually around 20% for males 20.0 percent
Cyprinus carpio Female Resting period Re-maturation of the ovaries requires > 3-4 months 3.5 months
Cyprinus carpio Male Age at sexual maturity In Victoria, males and females mature at 1 and 2 years of age. On average males mature one year earlier than females 1.0 years
Cyprinus carpio Male Male sexual dimorphism The abdomen of male carp does not become obviously distended but may become darker in colour and nuptial tubercles appear on the head and on pectoral fin rays Present
Cyprinus carpio Male Maximum GSI value Recorded estimates are usually around 10% for males 10.0 percent
Cyprinus carpio Spawning conditions Spawning temperature Spawning is low from 15-18°C, optimum 18-23°C, and ceases at 28°C 16.5 °C
Cyprinus carpio Spawning conditions Spawning water type Preferred spawning sites are lentic habitats with abundant food, warm water and protection from predators No category
Cyprinus carpio Spawning conditions Spawning depth The spawning act occurs in shoreline areas (water < 1 m deep) 1.0 m
Cyprinus carpio Spawning conditions Spawning substrate Obligatory plant spawners Phytophils
Cyprinus carpio Spawning conditions Spawning site preparation Open-substratum No category
Cyprinus carpio Spawning conditions Nycthemeral period of oviposition Spawning occurs during daylight Day
Cyprinus carpio Spawning conditions Mating system Spawning involves polygamous groups of one female and several males and is apparently triggered, at certain times of the year, by rising water that inundates terrestrial vegetation and periods of fine, warm weather Polyandry
Cyprinus carpio Spawning conditions Spawning release Carp are fractional spawners with indeterminate breeding season fecundity. Depending on local thermo and photo conditions, each female may spawn one to five batches of eggs per year. In India, carp spawn once. In southern France, Bengladesh, and west Bengal they may spawn twice. In tropical climates, carp are perennial spawners and spawn 4-5 times per year Multiple
Cyprinus carpio Spawning conditions Parity In Victoria, estimates of longetivy range between 15-40 years No category
Cyprinus carpio Spawning conditions Parental care Non-guarding No care
Leuciscus leuciscus Spawning conditions Spawning substrate Spawn in the main river channel over gravel substrata Lithophils
Rutilus rutilus Spawning conditions Spawning substrate Spawn over willow tree roots and long-leafed vegetation Phytophils
Tinca tinca Spawning conditions Spawning substrate Spawn amongst dense beds of submerged macrophytes No category
