NEFSC 2001 Spring Bottom Trawl Survey (AL0104, EK500)

The objectives of the cruise are to: (1) determine the spring distribution and relative abundance of fish and selected invertebrate species; (2) collect biological samples for studies of age and growth relationships, fecundity, maturity and food habits; (3) collect hydrographic and meteorological data; (4)
collect samples of ichthyoplankton and zooplankton; and (5) make data and sample collections for cooperative researchers and programs; (6) conduct a hydroacoustic survey between survey stations.
