because we found that agitating the weed in water did 

 not dislodge certain fishes (notably baUstids, anten- 

 nariids, syngnathids, gadids, and anguilliform lep- 

 tocephali). All fishes captured were preserved for later 

 identification and measurement. 



The arrangement of the list of fishes is phylogenetic 

 and follows Greenwood et al. (1966). Names follow 

 Bailey et al. (1970). The catch of each species is 

 separated by cruise (italicized) then listed as follows: 

 station where caught, total number captured, length 

 or length range in millimeters. Measurements are of 

 fork length, unless SL (standard length) or TL (total 

 length) are specified. The designation "mut" in- 

 dicates that identification or measurement was im- 

 possible due to mutilation of the specimen. 



RESULTS 



We caught 10,741 fishes belonging to 158 categories 

 including 51 families and 107 identified species (Table 

 2). Variety of species was greatest within the families 

 Carangidae (17 species), Balistidae (13 species), and 

 Exocoetidae (15 species). The proportions of the total 

 catch contributed by each family are shown in Figure 

 2. 



Over the inshore part of the shelf, catches were 

 augmented when we sampled along windrows of 

 debris and stems of Phragmites sp. and Spartina sp. 



Offshore catches were augmented when we sampled 

 among rafts of sargassum. 



Surface temperatures over the offshore part of the 

 shelf varied little throughout the year (Fig. 3-6, and 

 Clark et al. 1970) and this stability was reflected in a 

 fairly uniform catch during all four seasons. Fishes 

 strongly seasonal in occurrence (such as Mugil 

 cephalus, Mullus auratus, Pomatomus saltatrix, and 

 Urophycis regius) were taken mainly over the inshore 

 part of the shelf where temperatures ranged from 

 7.8°C in January to 28.1°C in July. 



Several species were surprisingly absent from our 

 collections (for example the carangids Trachurus 

 lathami and Selene vomer and larvae of the family 

 Acanthuridae) or were collected only rarely despite 

 their reportedly common status (for example Selar 

 crumenophthalmus, Lobotes surinamensis, and 

 Cantherhines pullus). These species may be common 

 under rafts of sargassum and susceptible to capture 

 by Dooley's (1972) purse seine but may not be strongly 

 enough surface oriented to be susceptible to capture 

 with a net towed within 1 m of the surface. 



Opportunities for comparing day and night catches 

 are limited since we never occupied a station long 

 enough to sample consecutively during both light 

 regimes. Catches of some species, however, were 

 noticeably greater at night. The halfbeaks
