Chemical cues and pheromones in the sea lamprey

Here we summarize the current understanding of the chemical cues and pheromones used by the sea lamprey during reproduction Previous reviews of sea lamprey olfaction focus primarily on applications to fisheries management in the Laurentian Great Lakes [16–20] Our objective is to develop a broader perspective on sea lamprey olfaction spanning from odorants up to evolutionary patterns

Coastal movements of sea lampreys – Lamprey Surveys

2014-2-17Sea lampreys seem to exhibit panmixia and studies indicate that anadromous sea lampreys locate spawning habitat based on pheromonal cues from larval conspecifics rather than through philopatry However a recent paper in the Canadian Journal of Fisheries and Aquatic Sciences has illustrated that the mechanism by which sea lampreys search for and select reproductive habitat is

PACIFIC LAMPREY RESTORATION IN THE ELWHA RIVER

2018-3-17Pacific Lamprey are anadromous and occurs along the Pacific Coast of North America from the Bering Sea to Mexico This species apparently does not home to natal streams but may use pheromones produced by larvae to locate suitable spawning and rearing habitats (Yun et al 2011) This reliance on larval pheromones may limit the ability of adults

The sea lamprey (Petromzons marinus) is a devastating invasive species that represents a significant impediment to restoration of the Laurentian Great Lakes There is substantial interest in developing environmentally benign control strategies for sea lamprey and many other aquatic invasive species that employ the manipulation of semiochemical information (pheromones and chemical cues) to

2017-9-28understand about sea lamprey in Lake Champlain is that their native status is still being debated today When sea lamprey control in Lake Champlain first began in the 1990s most people believed that the sea lamprey was a non-native nuisance species that had reached Lake Champlain through the Hudson-Champlain Canal

Chemical cues and pheromones in the sea lamprey

Sea lamprey use chemical cues and pheromones to identify productive spawning habitat coordinate spawning behaviors and avoid risk Manipulation of olfactory biology offers opportunities for management of populations in the Laurentian Great Lakes where the sea lamprey is a destructive invader We suggest that the sea lamprey is a broadly

Molecules

An enantiomeric pair of new fatty acid-derived hydroxylated tetrahydrofurans here named iso-petromyroxols were isolated from sea lamprey larvae-conditioned water The relative configuration of iso-petromyroxol was elucidated with 1D and 2D NMR spectroscopic analyses The ratio of enantiomers (er) in the natural sample was measured by chiral-HPLC-MS/MS to be ca 3:1 of (–)- to (+)-antipodes

The sea lamprey Petromyzon marinus an ancient and parasitic agnathan fish native to the North Atlantic invaded the Laurentian Great Lakes approximately a century ago triggering its fisheries to collapse Presently this species is held in check through a toxicant‐based control programme directed by a bi‐national treaty organization that seeks to develop a more broadly based integrated

A Review of Research in Fish Pheromones

Nonspecific diet metabolites as well as specific pheromones are important in chemical mediation of social behavior in fish The use of pheromones in fisheries started long before scientific proof of their existence Sea lamprey (Petromyzon marinus) pheromone is the first vertebrate pheromone that has been tested in the field as a pest control

A synthesized pheromone induces upstream

insect pheromone blends induce robust tracking responses in males and direct them into traps In vertebrates pheromones that induce strong and precise tracking responses in natural habitats have rarely been described Here we show in the sea lamprey ( Petromyzon marinus ) a vertebrate invader of the Laurential Great Lakes that a synthesized component of the male mating pheromone

Registration and application of sea lamprey

Since the identification of 3-trifluoromethyl-4-nitrophenol as a lampricide in the 1950s control of sea lamprey populations in the Great Lakes has largely relied on lampricides barriers and traps Lampricide treatments target larval lampreys in tributaries of the Great Lakes

Chemical cues and pheromones in the sea lamprey

2015-11-25Chemical cues and pheromones guide decisions in organisms throughout the animal kingdom The neurobiology function and evolution of olfaction are particularly well described in insects and resulting concepts have driven novel approaches to pest control However aside from several exceptions the olfactory biology of vertebrates remains poorly understood One exception is the sea lamprey
