The CPFV index from the previous year was included as a general measure of stock size.
The final logistic model indicated that presence of Pacific mackerel larvae could be predicted on the basis of zooplankton displacement volume, geostrophic flow, the CPFV index, the interaction between latitude and day of year, and the interaction between latitude and water temperature (Table 1).
barred sand bass catch values were nearly four times greater in the 1990s than in the 1960s despite only a doubling of fishing effort (CDFG unpublished data).
The continuous harvest of rockfish by the CPFV fishery has raised questions about the sustainability and health of this fishery.
The relative importance of particular rockfish species has changed with their availability over the years and with the CPFV fleet's response.
Mean percentages of fish taken by sea lions in relation to total catch (referred to as "mean percentage of fish taken by sea lions") for the commercial, CPFV, and skiff fisheries for onboard and dockside surveys from 1997 to 1999 were non-normal in distribution and were transformed by using the arcsine transformation for parametric statistical comparisons (Zar, 1996).
Mean catch per unit of effort, or the numbers of fish hooked per day per boat, in commercial, CPFV, and skiff fisheries data were non-normal and heteroscedastic, therefore, were they were transformed by using [square root of count + 1] (Harvey, 1987; Zar, 1996).
Species composition in the skiff and CPFV fisheries of the Monterey Bay region has previously been examined only for isolated years (Miller and Gotshall, 1965; Holliday, 1984) or for periods of a few years (Miller and Geibel, 1973; Reilly et al.
Starting in 1947, CPFV logbooks provide information on the number of passengers fishing and the number of fish caught in the region, but do not indicate individual species of rockfish.
A subset (out of 1900 otoliths used for aging) of 927 (603 from CPFV
and 324 from spearing) otoliths ranging from 1 to 44 growth increments was examined for edge analysis.
In recent years, Calforna's CPFV
fleet has experienced an economic declined.
fishing effort targeting multiple rockfish species was probably the most important recreational fishery component for cowcod prior to new restrictions on rockfish during 2000, although anglers on private vessels were also important.
