Fishing usually began to intensify about May, 

 and over the years second-quarter effort av- 

 eraged about 513 trips, which represented about 

 32 percent of the annual effort. Second-quarter 

 catches, which usually were about one-third of 

 the total annual catch, rose correspondingly to 

 an average of 1,414 metric tons or nearly three 

 times the average amount landed in the first 

 quarter. 



High catches were usually concentrated in 

 four regions in this quarter — off Hilo, off Cape 

 Kaea, off Kaena Point, and off Kahuku Point 

 (fig. 4). Together, they contributed a substan- 

 tial 41 percent to the second-quarter landings. 

 The catches off Hilo, which averaged only about 

 16 metric tons in the first quarter, increased 

 roughly nine times that amount in the second 

 quarter (table 3). Much of this sizable in- 

 crease contributed to the rise in the proportion 

 of fish taken in this quarter over the previous
