Researchers Ponder Over Origin Of Salmon Sea Lice
As per the findings of the new study, published in the recent issue of PloS One, sockeyes salmon residing in B. C. Fraser watershed are infected with sea lice after swimming past salmon farms.
Michael Price from the Raincoast Conservation Foundation expressed his fears against the ill effects that can be contributed by sea lice on the behavior and the population of wild salmons. It is also speculated that the lice can also be hub for different other diseases.
It was found in the study that in 2007, there were an average of 4.83 sea lice per fish and 1.61 in 2008 downstream from salmon farms, whereas for upstream it was reportedly 1.10 in 2007 and 0.95 in 2008.
Sea lice are the parasites, which occur mainly on wild salmon, attaching themselves on them. Lice infestations have put the population of salmon on risk, as the lice feed on the mucous, blood and skin of juvenile wild salmon.
Previous experiments have indicated that a single sea louse has the potential to kill a pink or a chum salmon fry. Researchers are having a tough time trying to develop chemical treatments against sea lice as they fear that it may harm other aquatic animals to.
