data collected from the winter fishery, most of 

 which occurs north of the MAB region. A more 

 structured design is required to address some of 

 these issues. The entire size and maturity stage 

 range needs to be sampled across the geographic 

 range of each survey and these data should be 

 augmented with opportunistic sampling outside 

 the area or time frame in which the sui-veys are 

 carried out. 



In summary, results from these two studies 

 complement each other to reveal patterns of re- 

 productive dynamics for L. pealeii that have been 

 suggested previously in other studies but that 

 have never thoroughly been investigated. The 

 high frequency of small squid present in spring 

 sui-vey catches indicates that winter spawning is 

 indeed an important component of reproduction 

 for the population, and biological analyses sug- 

 gest that this winter spawning occurs primarily 

 south of Cape Hatteras, rather than in the vicin- 

 ity of the offshore submarine canyons along the 

 edge of the northeastern U.S. continental shelf 

 from Hudson Canyon up to Georges Bank.

We would like to extend our thanks to John Gal- 

 braith of NEFSC. Ai-nie Howe of the Massachu- 

 setts Division of Marine Fisheries, Dave Simpson 

 of the State of Connecticut Marine Division, for 

 coordinated field sampling from sui-veys; Glenn 

 Goodwin and Gier Monsen of Seafreeze and Joe 

 Mantineo of Ruggierio Seafoods for commercial 

 samples. Lars Axelson, Glenn Goodwin, and Jim 

 Ruble shared their obsei^vations on spawning 

 grounds of Loligo pealeii with us. Chad Keith and Lynette 

 Suslowicz provided technical help in the cutting room. Jon 

 Brodziak provided the code for. and assistance with, the diel 

 correction analyses. We would like to thank John Boreman. 

 Steve Murawski, and Fred Serchuk for their thoughtful 

 and instructive reviews of this manuscript. EMCH would 

 like especially to acknowledge Steve Murawski's guidance 

 and help throughout the course of her Research Associate- 

 ship with NMFS. We also thank other scientific personnel 

 on NEFSC, MA, and CT bottom-trawl surveys and last, but 

 most definitely not least, the thousands of squid that have 

 sacrificed their lives for the advancement of sciencel Fund- 

 ing for EMCH was provided though the National Research 

 Council Research Associateship program.
