Invertebrates comprised the majority of commercial landings. In 1992, the total 
reported commercial landings were composed of 52% invertebrates (4.09 x 106 kg), 
28% reef fishes (2.19 x 106 kg), and 21% non-reef fishes (1.62 x 106 kg). In the 
recreational headboat fishery, reef fishes accounted for 92% of 0.107 x 106 kg 
average total annual landings from the Dry Tortugas and 86% of 0.201 x 106 kg landed 
from the Florida Keys since 1981. Average annual landings for other recreational 
fisheries were estimated at 1.79 x 106 kg for reef fishes (45%) and 2.17 x 106 kg for 
non-reef fishes (55%) from 1980 through 1992. Finer resolution of catch and effort 
data are needed, especially for recreational fisheries. Landings for some species varied 
greatly over time. The most conspicuous declines were for pink shrimp, combined 
grouper, and king mackerel while the most conspicuous increases were for amberjack, 
stone crab, blue crab, and yellowtail snapper. Landings of spiny lobster have generally 
remained constant. Fisheries closed to harvest included queen conch, Nassau grouper, 
jewfish, and stony corals. Effective fishing effort has increased over time with more 
participants and more effective fishing technology. Since 1965, the number of 
registered private recreational vessels has increased over six times, while the number 
of commercial and headboat vessels has remained stable. The number of management 
actions have continually increased and become more restrictive with increased fishing 
effort. Comparison of fisheries was complicated because different fisheries targeted 
different species and different sized organisms. Also, landings were sometimes 
reported by numbers and sometimes by weight. Measures of reproductive value and 
spawning potential are suggested as useful parameters for comparing effects of 
different fisheries. The new FKNMS provides a unique opportunity to shift management 
emphasis from a species approach to an ecosystem and habitat based approach.

[NO COPY OF PAPER AVAILABLE. ABSTRACT FROM SCHMIDT (1991).] Studies on 
carbonate sediment samples from the Florida Keys and Florida Bay (Cross Key Bank) 
and noncarbonate samples from Mexico Beach, Florida, indicate that amino acids 
comprise 15-36% by wt of humic substances from these sediments. Humic and fulvic 
acids extracted from carbonate sediments are characterized primarily by the acidic 
amino acids aspartic and glutamic acid. From these sediments it was found that lower 
mol wt fractions have appreciably higher relative abundances of the acidic amino acids 
compared to higher mol wt fractions. Based on typical values for carboxyl group 
content in humic substances, acidic amino acids may be a significant contributor of 
these functional groups. Carbonate surfaces selectively adsorb aspartic acid-enriched 
organic matter while noncarbonates do not.
