The sea lamprey is considered the helminth fish since they room the types that is gaining; they affix themselves to other varieties of fish through their countless sharp teeth and drain the organize fish of its human body fluids (Cherry, 2011). The host fish frequently die due to the fact that of blood ns or infections. They could not dice from a blood clot because the anticoagulant in the saliva the the sea lamprey keeps the blood thin. If the hold fish does survive, their reproduction has decreased. Some host fish that the sea lamprey vary from salmon, whitefish, walleye, north pike, burbot, lake trout, rainbow trout, chubs, part catfish and also lake sturgeon (Cherry, 2011; brand-new York room of eco-friendly Conservation, 2013; smith & Tibbles, 1980). One more fish sea lamprey room parasitic come arepaddlefish. No study has presented that sea lamprey have specific favorites in their host of choice. If friend would prefer a much better understanding of just how parasitic partnership work click on these examples,tooth decaying bacteria andAspergillus flavus (fungi). P.

By the at an early stage 1950’s humans decided these helminth fish have to be stopped. Castle tried electric barriers and used the toxin lampricide 3-trifluoromethyl-4-nitrophenol (TFM), which was used to ruin larval lampreys in streams (Smith & Tibbles, 1980). In between the 2 of these factors the population of the sea lamprey decreased and the populace of various other fish varieties increased. To store the population of sea lamprey to a minimum there have been federal and state programs and treatments created.


in ~ the an excellent Lakes region a tiny amount of sea lampreys have actually been discovered carrying level or roundworms for a part of their life (Cherry, 2011).
