 Screening nests is not possible on high density 

 nesting beaches, because screens are destroyed by 

 subsequent nesters. It is also difficult to 

 obtain temperature profiles from high density 

 beaches because the probes cannot be protected 

 from the turtles. He asked about the accuracy of 

 the mathematical equations used to estimate 

 nesting populations. 



Arrival survey methodology was reviewed. The 

 estimate of nesting females has not been 

 extrapolated to the total population. This aspect 

 is under study. 



Headlamps operating off solar power are used in 

 French Guiana. Further information is available 

 through him. 



(National representative of U.S.). Mrosovsky's 

 point about moratorium regulations causing 

 enforcement problems exists also with seasonal 

 closures or size limitations. She asked Murphy if 

 aerial nesting surveys are conducted comparably in 

 other states.

He agreed with Foster about enforcement. 

 Commercialism can generate funds for enforcement 

 while non-exploitation cannot. 



(National representative of Venezuela) . He 

 commented on Mrosovsky's comments on harvesting 

 "doomed" eggs subject to tidal inundation or 

 erosion representing negative genes. Observations 

 on Aves Island seem to indicate randomization of 

 nest site selection on the nesting beach. Eggs 

 laid in poor sites at one nesting are not 

 necessarily negative genes. It is dangerous to 

 utilize these eggs at the commercial level and may 

 be much better to translocate these eggs. 



Urged publication of these data. What is done 

 with eggs deposited in poorly selected nests sites 

 is part of one's conservation philosophy. You 

 must do what you think is best. 



(National representative of Dominica) . Has any 

 work been done on fishing mortality by the 

 swordfish fishery? Our knowledge indicates heavy 

 mortality especially in regard to D. coriacea .
