A Population Study Of The Peridiniidae Of Tomales Bay, Sidney Allen Cattell Jan 1966

A Population Study Of The Peridiniidae Of Tomales Bay, Sidney Allen Cattell

University of the Pacific Theses and Dissertations

It is the purpose of this study to present a quantitative survey of the family Peridiniidae in Tomales Bay over the six month period between October thirtieth and May sixth. Emphasis has been placed on variation in the total Peridiniidae population for this period, on the seasonal variation of individual species, and on the possible effects of hydrographic and climatic conditions on the population.

Historical. General descriptions of intertidal zonation have been published by many workers for almost all littoral areas, both marine and lacustrine (Doty, 1957; Glynn, 1965; Hedgpeth, 1957; Lewis, 1964; Pennak, 1951). The fact that animal species of the sandy shore are few in number eliminates many complex interspecific reactions, while great numbers of individuals make population studies feasible. In addition to certain general works (Dahl, 1952; Pirrie et al., 1932; Yonge, 1950) a number of papers have discussed causative factors or mechanisms for animal zonation.

Survey Of The Fishes Of Tomales Bay With Notes On The Life History Of The White Seaperch, Phanerodon Furcatus Girard, Tapan Banerjee

University of the Pacific Theses and Dissertations

Tomales Bay is situated in Marin County, about 40 miles north-west of San Francisco. This shallow bay averages about 1.5 miles in width and is about 12.6 miles in length, with an average depth of 12 feet (Johnson, Bryant and Hedgpeth, 1961). Oyster and herring comprise the main fishing industry, although the bay contributes a great amount of perch, smelt, halibut, and shark. Gill and seine nets are the most common gear used by fishermen.

The primary objectives of this study were: (1) to determine the species composition of the bay, and the relation between seining success at different localities …
