Catch by gear. — Three types of gear accounted for 94 per cent of 

 the fishery products taken off the coast of Cahfornia and landed in 

 the San Diego division during 1929. In the order of their importance 

 they were: Lampara nets, which accounted for 45 per cent of the 

 catch; lines, 43 per cent; and purse seines, 6 per cent. The catch by 

 lampara nets was made up principally of mackerel and pilchard or 

 sardine; that by lines was chiefly skipjack or striped tuna, mackerel, 

 and rockfishes; and that by purse seines was almost exclusively bluefin 



tuna.
