areas but that of brown shrimp was over 8 times greater at the weir than in Lake 4. The harvest 

 of both species was small in Lake 3. The drying of Lakes 3 and 4 during the spring and early 

 summer probably reduced brown shrimp production. Water control structures on Lake 3 were 

 inoperative by summer and apparently reduced access by white shrimp. 



Blue crabs were taken in abundance throughout the study area and the harvest totaled 10,554 

 kg, with 55.2% taken from the impoundments and weir area. 



Alligator gar (7,247 kg) and redfish (7,570 kg) were the finfish taken in greatest amounts on 

 the study area. Of the alligator gars taken, 70.5% were taken from within the management units, 

 and 74.1% of the redfish were taken outside the management units.
