river lamprey

The European river lamprey, also known as the river lamprey or lampern, is a jawless lamprey, scientific name Lampetra fluviatilis.

The increased mechanisation of agriculture in the area (arable on top of the escarpment, sheep on it and cattle in the valleys) led to a gradual decline during the inter-war periods and this led to the construction of three local authority housing estates (South St, Lampern View and Raglan Way).

River lampreys belong to the same genus as brook lamprey and are thought to be very closely related.

River lampreys migrate upstream from the sea to spawning grounds in autumn/winter.

It is home to brook lampreys, river lampreys and sea lampreys.

Lampetra fluviatilis (River lamprey)

European river lamprey, Lampetra fluviatilis (Linnaeus, 1758)

Jawless fishes include Brook lamprey, River lamprey, Sea lamprey.

Entosphenus similis (Klamath river lamprey)

Native species include Allis Shad, Brown Trout, European Eel and River Lamprey.

Spawning activity is greatest in the springtime (like brook lamprey) and river lamprey ammocoetes also spend several years in soft sediment before migrating to sea as adults.

The European river lamprey, also known as the river lamprey or lampern, is a jawless lamprey, scientific name Lampetra fluviatilis.

Current thinking suggests that European brook and river lampreys are a paired species, which means the river lamprey represents the anadromous (sea going) form of the resident brook lamprey.

Aquatic life includes river lamprey, Pacific lamprey, coastal cutthroat trout, Millicoma longnose dace, Umpqua chub, red-legged frogs, southern seep salamander, western pond turtles, coho salmon, Chinook salmon, steelhead trout, and others.

Petromyzon marinus, the sea lamprey, is the most sought species in Portugal and one of only two that can legally bear the commercial name "lamprey" (lampreia): the other one being Lampetra fluviatilis, the European river lamprey, both according to Portaria (Government regulation no. 587/2006, from 22 June).
