The metamorphosis of sea lamprey (Petromyzon marinus Linnaeus, 1758) allows young postmetamorphic individuals to migrate to the sea and start the hematophagous feeding. However, the information about this phase is very limited, especially for European populations. Herein, we provide for the first time a comprehensive study on the phenology of downstream migration, the timing and location of first feeding and the prey species in the River Ulla and its estuary (NW Spain). Results show that… 
Life cycle of the sea lamprey Petromyzon marinus: duration of and growth in the marine life stage
TLDR
It is suggested that at least a portion of the sea lamprey population can reach adult size in 1 yr of hematophagous feeding, and a period between completion of metamorphosis and reproduction of 1.5 yr (18 to 20 mo).
The haematophagous feeding stage of anadromous populations of sea lamprey Petromyzon marinus: low host selectivity and wide range of habitats
TLDR
The results suggest that the marine distribution of P. marinus is mainly related to coastal areas with part of the population widely dispersed in offshore areas and this remarkable capacity of inhabiting a broad range of aquatic ecosystems and exploiting different host species could have favoured the dispersal ability and evolutionary success of sea lamprey.
Petromyzon marinus (Petromyzontidae), an unusual host for helminth parasites in western Europe.
TLDR
Postmetamorphic lampreys sampled in rivers and northeast Atlantic coastal waters (western France) during spawning migration and a literature review of helminth parasites of P. marinus seem an unusual host that is probably infected through accidental ingestion of parasites by microphagous larvae (ammocoetes) and/or hematophagous postmetamorphs.
Accidental introduction of anadromous sea lampreys (Petrom yzon marinus Linnaeus, 1758) into a European reservoir
TLDR
Data suggest that this landlocked population of anadromous P. marinus into a reservoir in Europe was not successful and did not settle in the area because the haematophagous feeding phase was not viable.
Riparian vegetation subsidizes sea lamprey ammocoetes in a nursery area
Fluxes of organic matter (OM) from terrestrial ecosystems subsidize stream food webs, which support the production of ecologically and economically important species such as the sea lamprey
Marine and continental distribution and dynamic of the early spawning migration of twaite shad (Alosa fallax (Lacépède, 1803)) and allis shad (Alosa alosa (Linnaeus, 1758)) in the north-west of the Iberian Peninsula
TLDR
The findings indicate that both species of shad exhibit a coastal distribution near the rivers where they spawn, namely the Minho and Ulla rivers.
Trace element accumulation in anadromous sea lamprey spawners
TLDR
The accumulation of most elements analysed was low, except for Hg in the muscle, which exceeded the statutory limits for fish concentration, and a segregation of the samples into two groups, mostly based on Hg concentration.

The freshwater biology of adult anadromous Sea lampreys Petromyzon marinus
TLDR
The ability of adult anadromous Sea lampreys to feed and grow in fresh water demonstrates the relative ease with which landlocked forms could have been evolved in response to extreme environmental changes.
Biology of the North American Anadromous Sea Lamprey, Petromyzon marinus
TLDR
The sea lamprey (Petromyzon marinus) in the western Atlantic Ocean adjacent to North America is usually found within a depth of 200 m between latitudes of 30 and 53° and energy requirements for migration and reproduction are discussed in the context of parental investment.
Distribution, larval stage duration and growth of the sea lamprey ammocoetes, Petromyzon marinus L., in a highly modified river basin
TLDR
The number of annuli provides reliable age estimates when compared with length–frequency distributions analysis, and the growth rate of the sea lamprey ammocoetes displays strong seasonal patterns, and reaches its highest value during the first 2 years of larval stage.
Morphology, body size and behaviour of recently‐metamorphosed sea lampreys, Petromyzon marinus, from the lower River Severn, and their relevance to the onset of parasitic feeding
TLDR
The morphology, body size and time of capture of the River Severn sea lampreys provide very strong circumstantial evidence that these lampreys had been feeding for some weeks, presumably about to begin their parasitic marine life.

TLDR
An extensive European and North American literature is reviewed to provide a detailed and comparative account of lamprey ecology, particularly those riverine stages most likely to be affected by human activity, and points to those areas in which more information is required to form a basis for decision-making with regard to conservation requirements for these species in Ireland.

Although landlocked sea lampreys (Petromyzon marinus) attack all but a few of the smallest teleosts in the Great Lakes, the large cold-water species have received the most predation. Information on

TLDR
Observations on P. marinus and other lamprey species shows that variations in the time of completion of transformation or development of organs reflect the immediate needs of the animal.

TLDR
A study of anadromous sea lampreys at Love Lake, Washington County, Maine, provided evidence that newly transformed lampreys were attaching themselves and in many instances feeding upon landlocked salmon and other fishes.
