Figure 9. --Growth, measured in average lengths and 

 weights, of brown shrimp reared in static-water pond 

 (A) and circulating-water pond (B). 



Results in the circulating-water pond ap- 

 peared more promising because all the shrimp 

 did not die. Average lengths and weights of 

 shrimp during the first 77 days of this experi- 

 ment increased at a rate of 0.9 mm. (0.035 in.) 



per day and 0.06 g.

FLORroA BAY ECOLOGY PROJECT 



This project, started in fiscal year 1964, 

 has two principal objectives: (1) to establish, 

 by quantitative sampling, an index of abundance 

 of juvenile pink shrimp in eastern Florida 

 Bay and (2) to describe the habitat types 

 in the pink shrimp nursery areas of eastern 

 Florida Bay and relate these types to the 

 density of juvenile pink shrimp in each area. 



The Study Area 



Florida Bay, located at the southern tip of 

 the Florida Peninsula, is an extensive shallow 

 embayment intersected by grass-covered mud 

 banks and mangrove keys. Turney ( 1958) ^ sep- 

 arated the bay into four subenvironments based 

 upon degree of water circulation, influx of 

 ocean and fresh water, salinity and temperature 

 ranges, and distribution of moUusks, For 

 com.parative purposes, we have located 

 sampling sites in two of these subenviron- 

 ments, and we are considering a third site 

 (fig. 10). 



Development of Sampling Equipment 



Because we had to measure quantitatively 

 the abundance of juvenile pink shrimp in 

 Florida Bay, we considered several types of
