Island and Monterey (lat. 290 00' to 36e 30' N. and to long. 
l30e 00' W•. ). 
1. To intercept the ~lbacere migration and determine its 
route into the mainland fishing grounds. 
2.  To coll~ct physical and bielogical data which may be re-
lated to albacore occurrence. 
3. To tag and release albacore. 
1. (a) Some 3, 100 miles were scouted during daylight hours, 
using surface trelling gear. 
(b) Fifty-seven albacore were caught during the cruise. 
The first was taken in 59.90 F. water on June 9, 
about 540 mUes west of Pt. Buchen; four more, 
averaging 11 pounds, were caught June 18, approxi-
.mately 360 mUes west of San Diego in 590 to 60e F. 
water; the re.tnainder,averaging 14 pounds were 
taken June 20thrGugh 22, about 20 to 30 miles south

slides w'ere read, coded, and forwarded to the National 
Oc~anographic Data Center via U. S. Bureau of Com-
mercial Fisheries Radio StationWWD. 
(d) A w'ater sample, for salinity determination, and the 
temperature was obtained at lO-meters by a Nansen 
bottle cast at each BT station. 
(e) W.father observations were recorded every six hours 
and radioed to the U. S. Weather Bureau via station 
W'WD. 
'(f) Eleven night light stations were occupied while the 
vessel drifted on sea anch()r~ Pacific sauries 
(Cololabis sai~~) were observed at every station, in 
numbers r~Iiging from four or five individuals to
