3 FISHES AND FISH LARVAE COLLECTZD FRON ATLANTIC PLANKTOU CRUISES OF R /V PATi:IF INDER March 96 - March 96 As part of a continuing progr m to locate spawning areas, to obtain information on hydrogre.phic f ctors which influence spawning seasons end lurvel distribution, the second series of monthly cruises was mede from March 96 to }larch 96. This report lists the young fishes and fish larvae obtained by plankton collecting gear duri g these cruises. The gener3l objectives of this program end methods employed were outlined by Joseph et al. (960). Preliminery tabulations of the fishes and fish l rvne collected during the initial series of cruises have been re,o4ted by Massmann et al. (96i). The types of gear used and sa pling effort have been summarized by Wilson (96). For the present series, the station pattern and sampling methods were considerably modified from those used in the initial cr.uise series. In the Atlantic, si stations located t 0-mile intervals and etending 60 miles offshore, were established along the ' ancl 37 0; perellels of latitude. Two stations, located at 0.. mile intervals and e:>ctending 0 -miles offshore, were est bliohed along the 37 0' porallel of latitude. Two dditional stations located 80 miles offshore, one 60 miles offshore and two stations at the entrances of Sand Shoal and Wachepreague inlets were occupied on so e cruises. Eight stations, located et approimately 0-mile intervals, were established within the Chesapeeke B y system from near the Bay mouth through the Yo=k River and into the Pamunkey River. Station d sigmtions and locations are shown in Table ond.

4 - - A total of 7,0Sl young fishes and fish larvae were captured 6,493 of which were taken by routine to\ S.. Among these were 6 species, 7 forms identified to genera and l to family. Fifty-si specimens remain unidentified. The seasonal occirrence of larvae is presented in Table 3 and numbers of larvae captured from each aren by month and their length r nges are sho"t-m in Table lh The larvae captured by special tows are listed in Table 5. The identification of larval fishes is difficult.. Many have not t been described rrntl others have been so inadequately described that they =- :r.e indisti.nguishable from closely related froras; therefore, the list of.:9ecies uiust be considered as tentative. Among the raost difficult to differentiate nre larvae often present in great numbers, including the genera Alosa, Roccus, AnF.h_o...., Uro is, Prionotus. and Mvoocephalus.. I?or aid in the identification of some of the larvae the following have been most helpful:; Romeo and Alice He..nsueti, Chesapeake Biological Laboratory, Solomons, Harylcnd; G ace L. Orton, Scripps Institution of Oceanography, La Jolla, California; W. L. Klawe, Inter-Americe.n Tropical Tuna Commission, La Jolla, California; Daniel Cohen, U. S. National Museum, Washington, D. C., Robert H. Gibbs, Boston Ur.h ersity, Boston, Hassachusetts; and John Colton, U. S. Fish t Wildlife Service, Woods Role, Nessachusetts. Although collect:!.ng methods and station locations for the surveys ch.ffered from those made dring 96-6, it is possible to make gross comparisons of the ln vae obteined during the two periods. A nuraber of faros were captured during most of the same onths for both cruise series including yoortia yrannu, Ang rostrata, Gadus morhu., Micropogon undulatus, MYOccephalus spp., Poronotus trincanthus, Ai!-nocytes e.mericanus,

5 - 3 - _!'seudoj.?leuronectes mnericaill!. During the 96-6 survey some larvae were captm:ed late'i in the season than they we:r.e during initial cruises, these include Por,,atomus..alta, CytoscJ.Q!!. rew:lis.. and Prionotus spp. The collecting methods were not intended to be quantitative, yet the differences in numbers of some species of larvae captured during the two se ies of cruises were so great that they suggest differences in density of lm:-vae present in the area surveyed. For ezample, Merlncci. hil:i.near.is, common in winter collections during the initial series of c uises, did not occur during the second cruise series. f..qfonotus!!"..! canthus,.:-- donotus spp. and ]:seudopl uronec tes american.!}... were far more abudant during the fi st series of cruises, while Pmr.atoaus Jtatri was more abundant during the secon.d cruise series.
