Table 1 
Fish and shellfish landed in Broward County, Florida, during 1989. Species groups are identified by the following: BC = blue crab, 
BF = bait fishes, GS = grouper-snappers, ID = inshore demersals, IP = inshore pelagics, LB = lobsters, OD = offshore demersals, 
OP = offshore pelagics, SC = stone crab, SH = shrimps, and UM = unidentified miscellaneous fishes. Golden crab landings are 
included in the category “misc. invertebrates.”

February and June were least similar. About half (28 
out of 66) of all possible unique pair-wise compari- 
sons revealed significantly different assemblages 
(Table 3). These differences were usually due to 
changes in the proportion of landings contributed by 
swordfish and to the prevalence of lobster and 
baitfish. 
The composition of the assemblage landed in a 
particular month varied considerably. The assem- 
blage landed during any given month was signifi- 
cantly different from those of as few as two to as many 
as nine of the other eleven months. Assemblages of 
adjacent months were not significantly different, with 
the exception of July-August (owing to a sharp drop 
in swordfish landings and to a large increase in lob- 
ster landings at the beginning of the season) and 
September-October (owing to a sharp increase in 
swordfish landings and a general reordering of the 
dominance of other species) (Table 3). October was 
different from all months, except November and De- 
cember, and July was different from all months, ex- 
cept June and September. January was different only
