If the survival of younger animals is lowered, 

 then the relative reproductive value of adults 

 will increase. Although we worked with a 

 population that was not internationally exploited, 

 almost any reduction in juvenile survival was 

 found to increase the relative reproductive value 

 of adults.

Agreed with N. Frazer. Most changes will not 

 affect the general shape of the curve. It may be 

 higher or lower but the shape is pretty much the 

 same for nearly all changes. 



In a declining population, the relative value of 

 adults is higher than in a stable population. 



Fishermen don't go strictly by numbers. They will 

 take 10 small turtles in place of one large 

 turtle. Also, enforcement costs are much greater 

 for something like this. The additional costs may 

 come from research funds.

The moratorium must be accomplished through public 

 education. The local people must be told what 

 they will miss if they don't conserve the 

 resource. 



LAWRENCE: 



The practicality of using this model must be 

 considered. N. Foster and R. Marquez made good 

 points on this. N. Frazer did not present a 

 complete package. He should try to see how 

 practical it would be to explain this model to 

 someone who uses sea turtles as a source of food. 

 This model may make sense in larger areas, but not 

 on small islands. 



BOULON; 



GILLET; 



If the moratorium were put into effect, it would 

 be very good for sea turtle populations in this 

 region. However, all countries would have to 

 support it to make it work. 



The arguments about the moratorium will go on for 

 a long time. Dr. Frazer 's model probably is a 

 good management tool. The countries must work 

 together to decide what the size limits for taking 

 sea turtles will be. This size limit must apply 

 throughout our region if it is to work.
