Maryland JF-3-1-R David Cargo $100,000 



A study of the biology of sea nettles to develop potential methods for control of their 

 abundance - The Chesapeake Bay Biological Laboratory is continuing studies to obtain a 

 thorough knowledge of the life history of the sea nettle, determine its relation to various 

 environmental factors, determine the effect of this and related species on other Bay animals, 

 and to develop methods of control. 



Mississippi JF-2-1-R Philip Phillips $36,828 



Population studies of Mississippi Sound and inshore Gulf coelenterates with special emphasis 

 on noxious planktonie forms - This project investigates the life history and related en- 

 vironmental factors relative to population abundance of the noxious coelenterates. The Gulf 

 Coast Research Laboratory, Ocean Springs, analyzes biological samples and hydrographic data 

 collected from the estuaries to the shallow offshore islands. 



New York JF-3-3-R Kenneth Koetzner $22,000 



A study of the overwintering and germinating stages of floating marine algae in Great South 

 Bay, New York - The purpose of this project is to find out how to control the abundance of 

 marine algae. Samples of the upper portion of the sediment layer and overlying water are 

 being made and analyzed in the laboratory. Changes in temperature and salinity at selected 

 stations are being recorded. Overwintering stages collected from October to April are 

 germinated in the laboratory to determine species and growth. 



Puerto Rico JF-2-6-R Charles Cutress $17,4.72 



Investigation of the biology and control of noxious coelenterates occurring in the coastal 

 waters of Puerto Rico - Little is known of the noxious marine animals in Puerto Rico. A 

 survey is underway to determine 'the type, incidence, and severity of injury to bathers and 

 the occurrence and distribution of noxious marine invertebrates. Life history studies 

 will be made on those noxious jellyfish of primary importance. 



Virginia JF-3-2-R Dexter Haven |138,4.93 



An ecological study of the jellyfish (Chrysaora qiu.nquecirrha) - Research activities are 

 underway in the lower Chesapeake Bay and the James, York, and Rappahannock Rivers to define 

 the distribution and abundance of various stages of the jellyfish. The Virginia Institute 

 of Marine Science, Gloucester Point, will investigate possible predators and other causes 

 of mortality associated with the jellyfish. 



Snellfish 



There have been 65 projects approved and funded under the shellfish category, and 20 

 have been completed. 



Clam : 



Georgia 2-UU-K Walter Godwin Completed 1968 



Survey of a potential hard clam fishery - A survey along the Georgia coast to determine 

 whether a hard-clam fishery is feasible has been completed. Several types of harvesting 

 techniques were tested. 



Maryland 3-93-R H. T. Pfitzenmeyer $20,000 



Effects of Maryland hydraulic dredge on soft shell clams - This project will determine 

 how seasonal hydraulic clam dredging affects present populations and recruitment of 

 juvenile soft-shell clams. An area of the Maryland portion of Chesapeake Bay will be used 

 for the removal of clams and mechanical disruption of the bottom. Samples will be taken 

 every U months.
