their use of time is characteristic of the fleet 

 in general and if the pattern of their activities 

 for the years 1952 and 1953 is characteristic of 

 other years, we may analyze their records to 

 obtain an idea of the operation for the fishery. 



Table 1 gives the percentage breakdown of 

 all time available to the two vessels during the 

 2 years. The first four categories cover 

 periods during which the vessels are not active, 

 but are tied up to the dock or are out of the 

 water entirely. This time in port is more than 

 half of all time available, averaging 61.3 per- 

 cent for the two vessels in 1952-53. (However, 

 the "nonworking" time of the average laborer 

 on a "land" job for 8 hours a day, 5 days a 

 week, plus miscellaneous holidays is some- 

 thing over 78 percent of the year. The fisher- 

 men on the two vessels averaged more than 65 

 hours a week at sea.) The major part of this 

 time in port is spent in "rest and unloading," 



and the time required for unloading is doubt- 

 less a minor portion of this. A larger portion 

 of this time is spent with the vessel anchored 

 or tied up at the dock waiting to leave for the 

 fishing grounds. In addition, time that the crew 

 spends ashore for rest or with their families 

 may account for a substantial portion of this 

 time. The time spent traveling is that required 

 to go to and from port to the bait and fishing 

 grounds. 



Certain activities listed in table 1 can be 

 carried on by day or night, but others are re- 

 stricted to daylight or to darkness. The most 

 important activity during the day is scouting 

 and fishing, which can be done effectively only 

 during the day. Fishing for bait is another 

 important daylight activity. 



Since scouting and fishing and day baiting 

 require daylight, whereas essentially all other 

 activities (except night baiting) can be done at
