148 C'ALIFORXlb COOPERATIVE OCEANIC FISHERIES INVESTIGATIONSture gradient ; the temperature differences betweentwo stations (127.34 and 127.40) off Punta San Eugeniowas determined and from it was derived amonthly index of the intensity of upwelling at thiscape.These indices were then compared with the occurrenceof red crabs in the upwelled water by referenceto the numbers of occurrences and relative abundancesper month at a small grid of seven stations to thesoutheast of the cape in the direction presumed to be.taken normally by recently upwelled water. Thisinvestigation showed the regularity of the seasonalupwelling cycle from April until about July orAugust and also that the annual variation of frequencyand abundance of crabs to have been fargreater than any seasonal variation. The regressionbetween upwelling and 'frequency and abundanceof pelagic crabs indicates a zero correlation.VARIATION IN THE DISTRIBUTION BETWEENYEARSObservational data which showed that Pleuroncodeswas included in those species which extended theirrange to the north during the period 1958-1959 hasbeen presented by Berner (1960) Radovich (1961)Glynn (1961), and Boyd (1963) ; these data are summarizedbelow :,,I**I ? 1 I O N D f t l .

REPORTS VOLU&IE XI, 1 JULY 1963 TO 30 JUNE 1966 149During 1958-Multiple beach strandings at SanDiego, La Jolla and San Pedro.January 1959-Present off San Pedro.March 1959-Beach stranding at San Pedro.December 1959-Massive numbers present off SantaCruz, Anacapa, Santa Barbara Islands and Monterey.January 1960-Beach stranding at Monterey andSanta Catalina.It is now possible with the CalCOFI data to tracethis range extension to the north rather more closely;in Figure 5 are summarized the frequency of occurrencedata for the CalCOFI inshore area arranged bystation lines running approximately normal to thecoast and representing a latitudinal series at 26 intervals,each of 40 miles, extending from Cab0 SanLucas in the south to Monterey in the north. For eachstation line a percentage frequency of occurrence ofPleuroncodes is given for each month, ranked infour categories.The CalCOFI data show that a northward movementbegan some months before the first casual observationwas made of their presence off La Jollafrom a sport fishing boat; this movement started inthe area between Punta San Eugenio and Cab0Colnett in June and July of 1957 and by October someBoyd __.___________75-300 10.0-14.0
