4 DATA FROM VIRGINIA-MARYLAND COOPERATIVE FISH TRAWL SURVEYS IN CHESAPEAKE BAY AND 958 As a cooperative study conducted by the Virginia Institute of Marine Science and the Chesapeake Biological Laboratory, four trawl survey cruises were made from the mouth to the head of Chesapeake Bay. These cruises were planned to determine seasonal patterns of fish distribution, and to compare the distributions of fishes in Chesapeake Bay as a whole with the distribution in southern Chesapeake Bay and the York and Pamunkey rivers (Massmann, 96). Data including surface and bottom water temperatures and salinities, species and numbers of each species captured, and their length frequencies are listed in this report. Four cruises were made aboard the R/V Pathfinder - September, 957, and January, April, and July, 958. A total of 4 stations located at approximately 7-mile intervals from the mouth to the head of the bay were occupied on the September, April, and July cruises. In January the northe rn part of the bay was frozen ; therefore, only stations were occupied. At each station surface and bottom water temperatures and saliniti,es were measured and a 5-minute haul was made with a JO-foot otter tr.awl. Fishes were identified and measured and in some cases scale samples were taken. Sampling procedures were identical to those outlined by Massmann il al. (958). Station locations and depths are listed in Table. Water temperatures, saliities, fishes captured and length frequencies of subsamples of the :Eishes taken during the September 957 cruise are

5 - - listed in Tables -4; for the January 958 cruise in Tables 5-7; for the April 9 58 cruise in Tables 8-0; and for the July 958 cruise in Tables -3. A total of 3,774 fishes of 58 species were captured. In general, the distribution of fishes and their lengths approximated the distribution and lengths of fishes captured during cruises in lower Chesapeake Bay a.nd the York and Pamunkey rivers. Data collected during these joint efforts have been published by Mansueti (960_: 7-8; 96:9). The authors gratefully acknowledge assistance given in field work by J. Muncy and G.
