Book Description
Age analysis for 22 years (1980 excluded) showed that the overall percentages for female spawners was 53% (4-year olds), 38% (3-year olds), and 9% (5-year olds). The age composition of male spawners showed a high degree of variability throughout the study. Male chinook of age 2, 3 and 4 were dominant annually, but 5- and 6- year old fish were present in most spawning seasons. All chinook carcasses from which scales were collected were also measured for length (over 120 samples in 22 years). Decreases in mean length were documented for all age classes for each of the El Nino episodes that occurred during the study (1982-1984; 1992-1993; 1997-1998). The decreases in mean length appeared to carry forward for each cohort's age class. The total number of chinook redds was tabulated by counting "fresh" redds during weekly spawning surveys. The mean number of redds was 117 for the 23-year period with a mean of 0.9 redds per adult salmon or 1.8 redds per female.

Book Description
When the first edition of Inland Fishes of California was published in 1976, it was a benchmark reference. Since that time, our knowledge of California's freshwater fishes has dramatically increased. This completely revised edition incorporates a vast amount of new information and creates a fresh synthesis of the historical data. Written by the leading expert on California's freshwater fishes and illustrated with beautiful line drawings, this compendium is the single best source for understanding and identifying the state's freshwater fishes. It is an essential resource for anyone who needs to have accurate and detailed information on California's fishes at their fingertips. Since the 1870s, the state's native fishes have been joined by thirty-four alien species, which now dominate many bodies of water. This book treats both native and introduced species, first in a key for identification, and then in individual species accounts covering characteristics, taxonomy, names, distribution, and life history. Each account includes the author's personal assessment of how well the species is doing and problems associated with its management. Most of the native fishes are found only in California and show many wonderful adaptations for living in the state's diverse waters. Unfortunately, many are also in danger of extinction. The message underlying the first edition of this book was that we knew astonishingly little about many of California's inland fishes. Although our knowledge is increasing, full accounts of some native fishes may not be complete before they become extinct. Preventing the loss of native fishes is the major goal of this book, and Moyle makes important suggestions for conservation strategies as well as presenting up-to-date information on ecology, life history, and distribution. With this knowledge, preserving our native fishes becomes possible even in the face of the state's growing economy and population.
