Chief, Fisheries Statistics Investigation. Sandy Hook Marine Lab, November 1980—November 1985. Supervised staff of 25 -30 port agents operating out of field offices from Hampton, VA to Rockland, ME. Port agents collected fisheries landing data from dealers, interviewed vessel captains and collected biological samples essential for stock assessments needed for fisheries management. Data and samples were preprocessed and forwarded to NMFS facility at Woods Hole, MA for conversion to computerized files or further processing. Chief, Fisheries Statistics and Economics Branch, Northeast Fisheries Science Center, National Marine Fisheries Service, Woods Hole MA, December 1985—Dec 1990. Supervised Staff of about 50 including port agents collecting data, IT staff who developed software and converted the data to digital form, and Econom-ists who used the data to study impacts of fisheries management on fishing communities. Initiated first NMFS domestic fisheries observer program in the northeast U.S. and absorbed preexisting foreign observer program and staff. During the period from 1990 until my retirement in January 2001 the Northeast Science Center went through a series of reorganizations resulting in my being assigned different Branches to administer. These Branches included at times responsibilities for all groundfish and shellfish assessment cruises and deployment of observers to multiple fisheries from NC to ME and all US swordfish longline vessels in the Atlantic. The observer program expanded rapidly and grew to include multiple fisheries impacting protected species of marine mammals and sea turtles as well as fisheries monitored primarily for bycatch and discard of finfish and shellfish. I attended marine mammal take reduction team meetings in an advisory capacity and served on panels reviewing and approving grant proposals for marine mammal and sea turtle research.
