Table 60 shows for the years 19^0 and 1951j the craft and men 

 using both tuna and other gear, and the total of such duplications. 

 The following discussion describes in more detail the inter-relation- 

 ship between the tuna and other fisheries based on the data for the 

 year 19^0 given in table 60 « 



Duplications With Tuna Purse Seines 



Table 56 reveals that only 9 of the fleet of 102 tuna purse 

 seiners were engaged exclusively in tuna fishing with purse seines in 

 19^0 and table 60 shows what fisheries the other 93 vessels engaged in 

 ■when not fishing tuna. Some of these vessels engaged in more than one 

 fishery besides the tuna fisheryo The vessels of the tuna purse seine 

 fleet are based largely at San Pedro, but include also a few based 

 at San DiegOo All but one of the San Diego vessels operate a modified 

 form of purse seine for local bluefin only, converting to albacore 

 fishing, either with bait or troll lines, during the season when 

 albacore are abundant in southern California waters o They also fish 

 pilchards (sardines) with purse seines during the sardine season. One 

 of these vessels also operated sea bass gill nets for a short period 

 in 1950. A very limited number of the tuna purse seine fleet have 

 their home port at Monterey and San Francisco, but these also base 

 at San Pedro during the tuna purse seining season. 



The main body of the tuna purse seine fleet are vessels that 

 were built to engage in a combination of seining operations, such as 

 for sardines, mackerels, and tunas, A limited few will also purse 

 seine for market fishes, chiefly barracuda, off Lower California, when 

 market conditions are favorable. The above is confirmed in table 60, 

 which reveals that in 1950s 91 vessels of the fleet also were used 

 for sardine seining, 27 also for mackerel seining, and 2 for barracuda 

 and other market fishes „ The sardine season set by California law, 

 starts in central and northern California on August 1, and ends 

 January 15, and starts ir "outhern California on October 1, and ends on 

 February lo The mackerel seining season on which no legal season is 

 set, usually starts in August and ends in February or March, but these 

 fish may be taken in lesser quantities in other months also. Thus it 

 may be seen that the fleet of seiners can have practically a year 

 round operation by fishing for pilchards during the southern California 

 season, and for tuna in late winter and spring. In late summer and 

 early fall they may go to Monterey or San Francisco to fish for 

 sardines or they may fish mackerels, principally jack mackerel in
