hauls yielded a much larger percentage <strong>of</strong> young forms from <strong>the</strong> surface layers than<br />

did day hauls. Possibly <strong>the</strong> same condition might have occurred if night collections<br />

had been made in Chesapeake Bay (table 2).<br />

fishes were taken in larval or early postlarval stages<br />

TABLE 2.—The surface <strong>and</strong> subsurface distribution <strong>of</strong> planktonic fishes in Chesapeake Bay, expressed<br />

as <strong>the</strong> percentage <strong>of</strong> hauls in which <strong>the</strong> various species occurred<br />

[108 surface <strong>and</strong> 140 subsurface hauls wore made from May to October, 1929, <strong>and</strong> 111 surface <strong>and</strong> 168 subsurface hauls from April to<br />

December, 1930, omitting June. No fishes were obtained In 24 surface hauls <strong>and</strong> 47 subsurface hauls made in January <strong>and</strong><br />
