capture frequency of black skipjack in Tal)ie 1 is not 

 meant to reflect the true spawning frequency of the 

 afhilts. 



Thirty-nine specimens were held for laboratory 

 growth experiments. Their estimated lengths and 

 weights at capture are shown in Figure 4. The larger 

 fish in the catch (Fig. 3) survived capture and transfer 



in greater proportions than the smaller ones (Fig. 4). 

 The captive fish survived an average of 36 days in the 

 laboratory; most (64%) died in 30 days or less. Three 

 fish survived in excess of 130 days. The longest-lived 

 black skipjack grew in captivity for 167 days, and 

 attained an SL of 259 mm and weight of 336 g. It was 

 sacrificed when it ceased feeding due to eye infec-
