Description

Abstract: The majority of scientific studies on lamprey have investigated biological attributes, with few studies investigating historic abundance, detailed distribution and specific ecological requirements and role. Because of the paucity of information and concerns of declining lamprey population in the Pacific Northwest, the Applegate River Watershed Council (ARWC) with the Medford District of the Bureau of Land Management (BLM) collaborated to study lamprey populations in the Applegate River watershed of southwest Oregon (Close et al. 1995, Larson & Belchik 1998, Kostow 2002). The objectives of the study included: (1) Identifying species composition; (2) determining the distribution of lamprey species; and (3) relating the distribution of lamprey ammocoetes (juveniles or larvae) to physical stream characteristics. This paper summarizes the life histories of the two most common lamprey species in the Oregon, the Pacific (Lampetra tridentata) and Western Brook (Lampetra richardsoni), details the methods of study, reports the results and summarizes the findings. Also included are recommendations and suggestions for future lamprey work in the Applegate basin.

Purpose: To further investigate two lamprey species in the Applegate Basin area.
