Editing Fish migration (section)

==Historic exploitation==
Since [[prehistoric]] times humans have exploited certain anadromous fishes during their migrations into freshwater streams, when they are more vulnerable to capture. Societies dating to the [[Millingstone Horizon]] are known which exploited the anadromous fishery of [[Morro Creek]]<ref>C.M. Hogan, 2008</ref> and other [[Pacific Ocean|Pacific coast]] [[Estuary|estuaries]]. In [[Nevada]] the [[Northern Paiute|Paiute]] tribe has harvested migrating [[Oncorhynchus clarki henshawi|Lahontan cutthroat trout]] along the [[Truckee River]] since prehistoric times. This fishing practice continues to current times, and the [[United States Environmental Protection Agency|U.S. Environmental Protection Agency]] has supported research to assure the water quality in the Truckee can support suitable populations of the Lahontan cutthroat trout.
