TFM (3-trifluoromethyl-4-nitrophenol) is a common piscicide, i.e., a fish poison used to combat parasitic and invasive species of fish. [1]The substance was discovered in 1958 when researching means to combat sea lampreys and it currently remains the primary lampricide (lamprey-killer) in the Great Lakes area.
Lampreys contain these characteristics that define them as chordates. Lamprey anatomy is very different based on what stage of development they are in. [80] The notochord is derived from the mesoderm and is one of the defining characteristics of a chordate. The notochord provides signaling and mechanical cues to help the organism when swimming.
The Pacific lamprey (Entosphenus tridentatus) is an anadromous parasitic lamprey from the Pacific Coast of North America and Asia in an area called the Pacific Rim. [4] It is a member of the Petromyzontidae family. The Pacific lamprey is also known as the three-tooth lamprey and tridentate lamprey. Ammocoetes held by biologist in the Carmel River
The sea lamprey (Petromyzon marinus) is a parasitic lamprey native to the Northern Hemisphere. It is sometimes referred to as the "vampire fish". In its original ...
These lampreys may be beneficial to the rivers and lakes, due to their natural control of local fish populations. [5] Human populations can pose threats to these animals through pollution, siltation, and dredging. Larval lamprey must filter feed for numerous years and are vulnerable to changes in their environment during this time. For instance ...
Lampreys have been established as worthy models in understanding the development of higher vertebrate anatomy and physiology, with one such experiment determining that major classes of lipoproteins are similar in Mordacia to those found in humans. [7] M. mordax and the lamprey group have also been shown to be the lowest vertebrate to have clear ...
