generally occur in northeastern Florida Bay. In certain parts of northeastern Florida 
Bay, however, environmental conditions suitable for young pink shrimp apparently do 
exist for extended periods of time. Even at these times, however, few juveniles occur 
in northeastern Florida Bay. Another important aim of the field work is to accumulate 
information needed as background for 'estuary-seeding' experiments. If production of 
juvenile shrimp in Florida Bay depends on the availability of postlarvae, it may be 
feasible to introduce large numbers of young shrimp reared artificially to certain 
shrimp-deficient areas of the bay and thereby increase production. Sampling has 
established the usual abundance of pink shrimp and associated organisns at each station. 
With these background data, we may be able to determine the effect of introducing large 
numbers of young shrimp at a chosen location.

[NO COPY OF PAPER AVAILABLE. ABSTRACT FROM SCHMIDT (1991).] Postlarval pink 
shrimp were sampled at Buttonwood Canal and Little Shark River, from July 1965 to 
December 1967. Environmental effects on postlarval catches were observed and the 
catches of immigrating Penaeus were compared with commercial catches of Penaeus on 
the Grounds. Postlarvae were more abundant at night, during flood tides, in bottom 
samples, during new and first quarter lunar periods and during the summer. An index of 
abundance was selected at both stations with which it was possible to predict 61% of 
the monthly variation in commercial Tortugas catches.

Ecological studies in Florida Bay and the Florida Keys have produced a variety of 
information on young pink shrimp, Penneus d. duorarum, not previously available. These 
shallow waters are the prime nursery grounds for pink shrimp of the Tortugas fishery. 
Postlarvae of the pink shrimp enter the Florida Bay estuary from the Atlantic Ocean 
through channels in the Florida keys and love on the bottom of suitable, shallow-water, 
grassy areas. These shrimp settle in greatest numbers near shorelines, and apparently 
prefer bottoms with growths of shoal grass, Diplanthera wrightii. Quantitative samples 
of planktopnic postlarval shrimp enterting Florida Bay via Whale Harbor Channel were 
taken monthly for 30 months. Seasonal peaks of shrimp abundance were in the spring, 
summer, or fall. The numbers of incoming planktonic postlarvae are reflected by the 
numbers of benthic postlarvae caught at selected sampling stations in Florida Bay and 
the Keys. Planktonic and benthic postlarvae were most abundant from June to December 
in 1967. The numbers of shrimp in samples from 18 selected stations in October 1967 
give a general picture of shrimp distribution in Florida Bay and the Florida Keys. 
Northeastern Florida Bay has little water exchange with the Atlantic Ocean and contains 
a relatively small number of shrimp. The central Bay, with water circulation somewhat 
restricted by shallow water mudbanks, has moderate numbers of postlarval and 
juvenile shrimp, whereas the western Bay, with a large volume of incoming Atlantic 
water, has an abundance of young pink shrimp. The Lower Keys have moderate numbers
