4. Through its pesticide monitoring program in both ocean and Great 

 Lakes, the Bureau of Commercial Fisheries determined levels of pesticides 

 in shellfish, crustacean, and fish stocks. This information can be used to plan 

 pesticide utilization compatible with continued harvesting of commercial 

 species. 



5. An ecological study of Biscayne Bay, Fla., is investigating the effects 

 of thermal pollution from a nuclear powerplant on fish life. The Atomic 

 Energ)' Commission is supporting the study of noncommercial species, and 

 the Bureau of Commercial Fisheries those which are of commercial value. 



6. A comparison of the ecology of a natural marsh area with that of a 

 marsh altered by channeling and filling is being conducted by the Bureau of 

 Commercial Fisheries in Galveston Bay. 



7. The Corps of Engineers published a study on methods available for 

 the analysis of physical and ecological problems in estuaries.^ 



8. Numerical models and prediction programs to forecast storm surges 

 along the coastline have been developed and tested by ESSA and Navy. 



9. Acute (96-hour) toxic effect of several new pesticides on oysters, 

 shrimp, and fish were evaluated by the Bureau of Commercial Fisheries 

 under controlled conditions in the laboratory. Information obtained from 

 these and other toxicity studies was sent to the Pesticide Registration Division 

 of the Department of Agriculture to aid it in certifying pesticides to be used 

 in the marine environment. 



10. The Corps of Engineers published an engineering analysis of the 

 coastal engineering aspects of the tsunami wave created by the Alaskan 

 earthquake of 1964. 



1 1 . Following up an earlier initiative of the Marine Sciences Council, the 

 Corps of Engineers sponsored a study on the effects of engineering activities 

 on coastal ecology. 



Opportunities for tlie Future 



The coastal zone, with its multitude of opportunities, also presents a 

 multitude of problems. Many of these are largly scientific and technological, 

 and to these our scientists and engineers can provide answers. Far more 

 difficult questions arise from the conflicting desires and needs of the many 

 different occupants and users of the shoreline. The challenge before us is 

 to reconcile these competing interests — to find opportunities for multiple, 

 compatible uses of the shoreline and inshore waters, and to maintain op- 

 tions for future uses not foreclosed by degradation of the resource. 



This will require identifying multiple compatible uses and also encourag- 

 ing the development of effective mechanisms for making rational choices 

 among incompatible uses. Implementation of those initiatives of the admin- 

 istration's five-point program which relate to the coastal zone should assist 

 in making available both the basic information and the management tools 

 for making wise decisions.
