The greater number of collections 

 containing menhaden larvae during 

 cruise 5 than during cruise 1, both of 

 which occurred during the sannetime of 

 year, is believed due to the changes in 

 methods of collecting. During cruise 1, 

 a half-meter silk plankton net was towed 

 slowly at an estimated speed of 1-2 

 knots. During cruise 5, metal plankton 

 nets were towed more rapidly. A Gulf III 

 sampler was towed at 5-6 knots for all 

 but seven of the regular stations occu- 

 pied, and a Gulf lA sampler was towed 

 between stations I to 43 at 8-10 knots. 

 A description of the samplers is given 

 by Arnold and Gehringer (1952). The 

 absence or scarcity of larvae during 

 cruise 1 is believed due to their ability 

 to avoid a slow-nnoving net.
