 Bottom type, abundance of predators and fouling organisms, and abundance and size of oysters 

 present have been, recorded. 



Florida 2-52-D Robert Ingle $71,300 



Construction of artificial oyster reefs - Natural oyster reefs are being established from 

 Tampa Bay north to Choctawhatchee Bay. This project will create permanent areas for oyster 

 attachment and growth, and, consequently, commercial production. 



Georgia 2-10-R Thomas Linton Completed 1968 



Feasibility study of methods for improving oyster production in Georgia - An inventory of 

 the intertidal resources has been completed. Pilot studies to find the best methods of culti- 

 vation are completed on pond and raft culture. 



Hawaii H-2-R Henry Sakuda $U,229 



Investigation for the development of a commercial oyster industry - Seed oysters are col- 

 lected from West Loch, Pearl Harbor, Oahu, and transplanted into Hilo Bay on the island of 

 Hawaii, Kaneoke Bay on the Island of Oahu, and other selected ponds and estuarine areas. The 

 oysters are sampled routinely for changes in .condition, growth, and mortality. 



Louisiana 2-23-D John Loy, Sr. 161,000 



Oyster lease control monuments - Survey control monuments are being established throughout 

 the oyster-growing areas to aid in accurate surveys of waterbottoms for leasing purposes. 

 The control monuments are constructed of concrete and reinforcing steel rods and placed at 

 about -g--mile intervals.

Evaluation of experimental oyster tonging reefs in Calcasieu Lake - The purpose of this pro- 

 ject is to evaluate the development of oyster tonging reefs in Calcasieu Lake. About 

 10,000 to 15,000 cubic yards of clam shell will be planted at predetermined locations. The 

 shell planted will form a mat of about A inches in depth. Monthly checks will be made to 

 determine the success of spa tf all. 



Maryland 3-20-R Victor Sprague Completed 1968 



Development of a disease resistant oyster brood stock - Various strains of oysters have been 

 tested for relative resistance to diseases. Laboratory and field studies have been made 

 to develop a resistant brood stock. The stocks are tested in pond culture experiments. 



Maryland 3-23-R William Roosenburg Completed 1967 



Study of the effects of thermal pollution on (Crassostrea virginica) in the Patuxent Estuary - 

 A study of oyster growth, mortality, gonad development, and condition has been completed in 

 the upper Patuxent estuary. Stations were located 1,000 feet to 7 miles from the heated
