grams, in particular the Pollutant Transfer Program and the Con- 

 trolled Ecosystem Pollution Experiment (CEPEX). CEPEX was felt 

 to be the other half of an overall effects program. The Executive Com- 

 mittees of the Programs could arrange for data exchange and joint 

 planning. 



3. The participants recommend that a field experiment be carried 

 out on shipboard in order to utilize some of the non-lethal biological 

 tests developed by the Effects Program. Such a joint experiment might 

 also involve Transfer and CEPEX investigators. 



Specific Recommendations 



1. It was recommended that biological effects studies on biota from 

 the continental shelf and open sea be continued. Such studies 

 should go beyond lethal dose experiments to sub-lethal effects. The 

 mechanisms for both killing and sub-lethal biological effects are 

 poorly understood and require further study. 



2. It was recommended that representative species of organisms from 

 the following groups be studied: 



(a) phytoplankton of the open ocean and coastal areas 



(b) fish of the continental shelf 



(c) marine Crustacea, with special focus on crab, shrimp, amphi- 

 pods and mysids 



(d) mollusks 



(e) echinoderms 



3. For comparison of relative sensitivity toward pollution it was rec- 

 ommended that similar but less extensive studies be done on estu- 

 arine organisms. 



4. It was recommended that increased effort be directed at two 

 difficult technical problems which have emerged from the Program 

 (i) the cultivation in the laboratory of open ocean marine plants 

 and animals (ii) the development of improved physiological and 

 biochemical parameters for detecting biological effects. 



5. It was recognized that the Effects Program is highly biological in 

 nature and should remain so but it was recommended that strong 

 chemical projects be carried out in support of the biology especi- 

 ally with regard to characterizing petroleum toxins. 



6. It was recommended that geochemical transport, accumulation and 

 retention studies be done for selected pollutants. Such studies 

 should be related to the IDOE Pollutant Transfer Program.
