  • Parasites of Largemouth Bass (Micropterus Salmoides)
    PARASITES OF LARGEMOUTH BASS (MICROPTERUS SALMOIDES) IN NORTHERN CALIFORNIA By Daniel J. Troxel A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of The Requirements for the Degree Masters of Science Natural Resources, Fisheries November, 2010 ABSTRACT Parasites of largemouth bass (Micropterus salmoides) in northern California Daniel J. Troxel A total of fifty largemouth bass (Micropterus salmoides) were collected from Clear Lake, Lake Berryessa, Lake Sonoma, Trinity Lake and the Sacramento – San Joaquin River Delta. All fish were infected with at least one parasite, with the exception of one juvenile fish from Trinity Lake in which no parasites were found. The following parasites were observed in largemouth bass: Actinocleiudus unguis, Clavunculus bursatus, Clinostomum complanatum, Proteocephalus pearsei, Contracaecum sp., Hysterothylacium (?) sp., Spinitectus carolini, Camallanus sp., Neoechinorhynchus cylindratus, Myzobdella lugubris, Batracobdella phalera, Ergasilus centrarchidarum, and Argulus flavescens. In addition to these identified parasites, I also found an unidentified leech and Proteocephalus sp. plerocercoids, which could not be identified to species. All of these parasites have been previously reported infecting largemouth bass. Clinostomum complanatum, Contracaecum sp. and Myzobdella lugubris, have been previously reported in California; but these are the first known reports from largemouth bass in California. Actinocleidus unguis was the only parasite found that has previously been reported to infect largemouth bass in California. iii ACKNOWLEDGMENTS I would first and foremost like to acknowledge my parents, without their support over the past two years this project would not have been possible. I would like to thank Dr. Gary Hendrickson for his contributions in the laboratory during the long process of identifying parasites.

    105TH CONGRESS REPORT 1st Session HOUSE OF REPRESENTATIVES 105±9 "! DESIGNATION OF TRINITY LAKE, CALIFORNIA MARCH 10, 1997.ÐReferred to the House Calendar and ordered to be printed Mr. YOUNG of Alaska, from the Committee on Resources, submitted the following REPORT [To accompany H.R. 63] [Including cost estimate of the Congressional Budget Office] The Committee on Resources, to whom was referred the bill (H.R. 63) to designate the reservoir created by Trinity Dam in the Central Valley project, California, as ``Trinity Lake'', having consid- ered the same, report favorably thereon without amendment and recommend that the bill do pass. PURPOSE OF THE BILL The purpose of H.R. 63 is to designate the reservoir created by Trinity Dam in the Central Valley Project, California, as ``Trinity Lake''. BACKGROUND AND NEED FOR LEGISLATION H.R. 63 would designate the reservoir created by Trinity Dam in the Central Valley Project, California, as ``Trinity Lake.'' Under the provisions of P.L. 88±662, the reservoir is currently designated as ``Clair Engle Lake,'' and therefore requires legislation in order for the name to be changed. Trinity Dam and the reservoir on the Trinity River regulate a drainage area of over 728 square miles. Trinity Dam, completed in 1962, is an earthfill structure 538 feet high with a crest length of 2,450 feet. The reservoir has a maximum storage capacity of 2.448 million acre-feet of water. Releases from the reservoir are used to generate power at Trinity, Lewiston, Spring Creek, Judge Francis Carr, and Keswick powerplants, and for consumptive use in the Central Valley Project.
