The garibaldi, Hypsypops rubicundus, is a sexually monochromatic pomacentrid found in rocky subtidal areas of Southern and Baja California. During the spawning season, males attempt to attract females to a nest of red algae located within individually defended territories. Females were observed to enter the nests of several males before...
Spawning fall Chinook and coho salmon were counted. Statistics give historic counts. Less area was surveyed in 1975, and methods of data analysis were re-evaluated.
The fall chinook index of abundance was 128% of the long-term average, and presumably would have been even higher had survey conditions in the central and north coast not been so difficult.
The surveys of spawning fish in coastal rivers in 1971 indicate that stocks of chum salmon remain at a low, although apparently stabilized level. Fluctuations are probably the result of year-class survival and age at maturity, rather than continued decline of the species.

Spawning coho, chinook, and chum salmon are annually surveyed in coastal streams by Department of Fish and Wildlife personnel. Annual peak counts of spawning salmon provide data for computing an index of coastal escapement which is plotted each year to chart spawning salmon trends over a period of years. This...
