Download or read book Biology of the Pile Perch Rhacochilus Vacca in Yaquina Bay Oregon written by Paul Gordon Wares and published by . This book was released on 1971 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growth, reproduction, food habits, and parasites of pile perch were investigated in Yaquina Bay, Oregon between April 1966 and July 1967. The research disclosed that pile perch live at least 10 years. Males and females of given ages are close to the same size up to age IV, after which females are increasingly larger than males. The diet varies between seasons and localities. Pile perch are carnivorous feeders, obtaining food from the bottom or protruding surfaces in the littoral zone. Principal foods are barnacles, mussels, the bay clams, crabs, mud shrimp and tube dwelling amphipod. None of the pile perch examined was heavily parasitized. Infestations of gill copepods vary seasonally.

Download or read book Biology of the Redtail Surfperch Amphistichus Rhodoterus from the Central Oregon Coast written by Donald E. Bennett and published by . This book was released on 1977 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data on certain aspects of the life history of the redtail surfperch were collected along the central coast of Oregon, from April 1967 through April 1969. Annulus formation occured during February through June, usually earlier in young than in older fish. Mating occurred from late December to early January, and the young were born from July through September. The number of embryos per female ranged from 1 to 39 (mean 13.3) and increased linearly with the length and weight of the females. Food of the fish from the surf zone included crustaceans (by far the most important group in both frequency of occurrence and total volume) and (in order of decreasing importance) fishes, mollusks, and polychaetes. Parasites of the redtail surfperch were immature nematodes (Anisakinae) ; the digenetic trematode Genitocotyle acirra; the monogenetic trematode, Diclidophora sp.; and the copepods, Caligus sp., Clavella sp., and Argulus catostomi.

Book excerpt: In the compiling of this book, the vast literature dealing with the descriptive morphology, histology and cytology of teleost development has been combed and integrated. The book is divided into 21 chapters, starting with the egg and embryonic development up to hatching. This is followed by a description of ectodermal, mesodermal and entodermal derivatives and the development of various organs.

Download or read book Is It a House written by Amanda K. Taylor and published by University of Washington Press. This book was released on 2012-04-01 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prehistoric houses on the Northwest Coast were built from wood, often within piles of discarded shells, leaving little archaeological evidence from which to confirm their presence. Is It a House? uses multiple lines of evidence to investigate whether the U-shaped depression surrounded by shells at the English Camp site on San Juan Island was originally a house constructed by native peoples. Each chapter addresses a different kind of evidence, including artifacts, sediment, faunal remains, and stratigraphy. The quantitative and qualitative analyses used to examine the evidence reveal new directions and insights for identifying houses in similar contexts. The editors introduce the research in the context of current and past Gulf of Georgia (Coast Salish) archaeology, and end by synthesizing the research evidence.
