1. Upwelling, offshore transport, and the availability of rockfish in central California - Ainley, David G.; Sydeman, William J.; Parrish, Richard H.
EXTRACT (SEE PDF FOR FULL ABSTRACT): We used the diet of a seabird, the common murre (Uria aalge), nesting on Southeast Farallon Island and feeding in the Gulf of the Farallones, California, as an index to abundance of juvenile rockfish, then related fish abundance to indices of turbulence and upwelling over an 18-year period, 1973-1990. Strong, persistent upwelling or downwelling led to reduced availability of fish in the study area, in contrast to great abundance when upwelling was mild or pulsed. ... On the basis of our study, one effect might be that fishes thought strong enough to resist Ekman transport...

2. Climate forcing of Pacific herring recruitment and growth in southern British Columbia - Ware, Daniel M.
Over the last 50 years, much of the variability in ocean climate and herring recruitment has occurred at two dominant periods centered around 5 and 16 years. Herring growth has also exhibited a dominant 5- and 18-year periodicity. A recent analysis of a number of relevant time series suggests that interannual variations in oceanic conditions off the west coast of Vancouver Island affect survival of herring and their principal predator, Pacific hake, which also exhibits a marked 16-year oscillation in abundance. Thus the dynamics of the herring stock are modulated by a combination of climate and predator forcing. Much of...

3. Interpreting long-term fish landings records: environment and/or exploitation? - Sund, Paul N.; Norton, Jerrold G.
The California Department of Fish and Game data base of California commercial fish landings for the period 1928 to 1985 has been assembled in computer accessible form at the Pacific Fisheries Environmental Group in Monterey, California. Time series for fishes whose landings are known to vary during periods of ocean warming were compared to time series of sea surface temperature. Expected patterns of variation were confirmed in the seasonal cycle, but were less clear on the interannual scale. When interannual variation was considered, the most serious hindrance to interpretation of the landings series appeared to be the continued reduction of...

5. Report on the biology of Pacific hagfish, Eptatretus stouti and the development of its fishery in California - Kato, Susumu
Hagfish, often referred to as "slime eels", are familiar to most fishermen as pests that frequently devour fish caught by trap, hook, and gillnet. In the Republic of Korea (ROK or South Korea), however, hagfish are sought after as valuable fish not only for their edible flesh, but also for their skin, which is processed into leather used to make expensive purses, shoes, and other articles. In fact, because of a shortage of hagfish in the waters near the ROK, the leather industry there has started to import hagfish, first from Japan in the mid 1980's, then from the United...
