Abrir o appDescrição
Rutilus rutilus, commonly known as the Roach, is a widespread freshwater fish of the family Cyprinidae. It is a highly adaptable and resilient species, often found in large shoals across a vast geographical range. Its ecological role is significant as both a prey item for larger piscivorous fish and birds, and as a consumer of various aquatic invertebrates and plant matter. It is a key component of many European freshwater ecosystems.

Dicas de identificação
Eye Color
The most distinctive feature is the bright reddish-orange iris, which is usually very prominent.
Body Shape
A relatively deep, compressed body with silvery flanks and a darker back.
Fin Position
The dorsal fin typically originates directly above or slightly behind the pelvic fins.
Mouth
A small, terminal mouth, not downturned or upturned.
Habitat
- Tipo de água
- freshwater
- Profundidade
- Typically found in shallow to moderate depths, but can inhabit deeper waters.
- Ambiente
- Prefers slow-moving or still waters such as lakes, ponds, canals, and the lower reaches of rivers. Tolerant of a wide range of water conditions, including some eutrophication. Often found near aquatic vegetation or submerged structures.
- Distribuição geográfica
- Widespread across Europe and parts of Asia, from the British Isles and Scandinavia in the west to the Ural Mountains and Siberia in the east. Absent from the Iberian Peninsula (except for some introduced populations), southern Italy, and Greece.
Informações sobre aquário

- Temperamento: peaceful
- Alimentação: omnivore
- Tamanho mínimo do aquário: 200 gallons (for a small shoal)
- Temperatura: 10-22°C (50-72°F)
- Nível de pH: 6.5-7.5
- Dureza da água: 5-20 dGH
- Compatibilidade: Generally compatible with other peaceful, coldwater fish of similar size. Avoid aggressive or fin-nipping species.
- Requisitos especiais: Requires a well-filtered, mature aquarium with ample swimming space. Prefers planted areas and some hiding spots. Best kept in shoals of 6 or more individuals to reduce stress and encourage natural behavior. Sensitive to poor water quality.
Informações no ambiente natural
- Estado de conservação: least concern
- Sazonalidade: Spawns in spring (April-June) when water temperatures rise. Active year-round, though feeding activity may decrease in colder months.
- Preço de mercado: Low (primarily for bait or coarse fishing)
- Importância comercial: low
- Sabor: Mild, somewhat earthy
- Textura: Flaky, can be bony
- Métodos de preparo: Frying, Baking, Smoking, Pickling
- Valor nutricional: Good source of protein and omega-3 fatty acids, though often considered a 'coarse' fish for consumption due to bones.
Fatos principais
Hybridizationbehavior
Roach are known to readily hybridize with other cyprinid species, most notably with Bream (Abramis brama) to produce 'Roach-Bream' hybrids, and sometimes with Rudd (Scardinius erythrophthalmus). These hybrids can be difficult to identify.
Dietary Flexibilitybehavior
The diet of Rutilus rutilus is highly flexible and opportunistic, shifting with age and seasonal availability. Juveniles primarily consume zooplankton, while adults feed on a wide range of benthic invertebrates (insect larvae, crustaceans, molluscs), detritus, and some plant material.
Shoaling Behaviorbehavior
Roach are highly social fish, typically forming large shoals, especially when young. This shoaling behavior provides protection against predators and can aid in foraging efficiency.
Indicator Speciesinteresting
Due to their wide distribution and tolerance to various environmental conditions, Roach are often used as an indicator species for water quality and ecosystem health in European freshwater systems.
Longevityrecord
While typically living 5-10 years, some individuals of Rutilus rutilus have been recorded living up to 15-20 years in optimal conditions.
Informações de segurança
Seguro- Nível de segurança: safe
- Venenoso: Não
- Comestibilidade: edible
- Observações de manuseio: No specific handling precautions are required beyond standard fish handling practices to minimize stress to the fish. They do not possess venomous spines or teeth. Handle gently to avoid damaging scales or fins.
Espécies similares
Rudd
Scardinius erythrophthalmus
Rudd have a more upturned mouth, a more golden-bronze coloration, and their dorsal fin is set further back, originating behind the pelvic fins. Their eyes are also typically more orange than red.
Bream
Abramis brama
Bream have a much deeper, more laterally compressed body, a longer anal fin, and a protractile, downturned mouth. Their coloration is often more bronze or olive.
Ide/Orfe
Leuciscus idus
Ide are more elongated and streamlined, with a larger mouth and typically a more silvery-grey coloration. Their fins are not as intensely red as those of the Roach.
