N. Frazer's presentation was based on population 

 models. This must be put into language that the 

 public can understand. This needs to be done 

 especially for developing countries. What are the 

 effects of long term harvesting of eggs and young? 



The long term effects of harvesting eggs, 

 juveniles, and adults would be to deplete the 

 resource very rapidly. Harvesting eggs and 

 juveniles would deplete the resource more slowly. 

 Harvesting only the eggs will deplete the resource 

 more slowly still. 



Some places may choose to impose a size limit on 

 taking sea turtles rather than a moratorium. The 

 national representatives need to understand N. 

 Frazer's reproductive model to explain it to 

 fishermen and other appropriate people when they 

 return home.

N. Frazer's model was supported, but the model 

 must be explained to the people affected by its 

 implementation . 



As talk about the moratorium continues, the 

 problems with the incidental take of sea turtles 

 must not be forgotten. 



Lots of data show sea turtle populations don't 

 shift from one area to another. Local declines 

 cannot be explained. Something to prohibit trade 

 in sea turtles and their products must be done. 



Green turtles have been tagged at the Tortuguero 

 rookery for over 30 years. About 30,000 sea 

 turtles have been tagged at Tortuguero, and not 

 one has been found nesting elsewhere — a strong 

 case for philopatry. 



The chair has been thoroughly educated in 

 management options and now has to evaluate how the 

 various options could apply in his area. How 

 these options could apply in more detail must be 

 discussed with colleagues and other interested 

 parties. 



The migratory patterns of sea turtles need to be 

 studied to determine if a world wide moratorium on
