Seasonal age composition summaries of the Pacific sardine in numbers of fish by year class and age are presented in graphic form by port or region of landing for the seasons of 1932-33 through 1959-60. A pictorial history of the sardine fishery for 28 years is thus presented in the bar charts, which illustrate the relative importance of certain year classes in the seasonal catch totals, and in the fluctuations of those totals over this period.

The Pilchard: Biology and Exploitation discusses various concerns in the global pilchard industry. The book is comprised of 23 chapters that are organized into five parts. The text first introduces the biology of pilchard, its geographical distribution, and its zoological classification. Parts II to IV tackle the various issues in pilchard industries in different regions, namely, England, California, South Africa, and West Africa. The coverage of the book includes catching, processing, demand, and profitability. The book will be of great use to individuals involved in the pilchard industries. Researchers of fisheries science will also benefit from the book.

Estimates of the age composition of the commercial landings of Pacific sardine (Sardinops caerulea) at Monterey and San Pedro, for the seasons 1938-39, 1939-40, and 1940-41 are given. A mode-subtraction method was used to make the season of 1938-39 estimates and its accuracy is discussed. Estimates for the other seasons were obtained by applying the age data collected during those seasons. All known age-composition data for the Pacific sardine for the seasons 1932-33 through 1959-60 are presented. Estimates of year-class size in numbers of fish are given by season and port of landing. An annotated bibliography of papers containing basic age and length data on the Pacific sardine is included.

Includes entries for maps and atlases.
