Table 19/ — Record of mackerel eggs and larvae caught during cruises I to VII in 1983 — Continued 



CRUISE VII— Continued 



Note. — The above given table docs not include stations at which hauls were made and no eggs or larvae of mackerel found. All 

 these hauls were completely sorted for large larvae, but only fractions for eggs and small larvae. In the following enumeration that 

 includes all such stations, the fractions of hauls sorted are included in parentheses, and the letters U and L refer to upper and lower 

 hauls, respectively. Unless otherwise specified, the fraction given for upper haul was sorted for both eggs and larvae, those of the 

 lower haul for larvae onlv. Cruise I: Martha's Vineyard I 2)327 (U 0.0187 for eggs) (0.0747 for larvae): Martha's Vineyard II 21328
