20 live ones put back in nest

18 determined to be unviable

Dumped along with 20 hatched eggs


46 thought to be still viable put back into nest .


2 hatched eggs of 46 found on check one week later 12/17


11/14 - first inventory check of nest 69,

Viable eggs found everything reburied and left to continue incubation

12/3- check to see condition of egg if still viable,found hatchlings close to surface. Green hatchlings rebury and caged.

At SCDNR MTP guidance told to let sit a week.

12/10- check of nest found results listed above . Per SCDNR MTP guidance told to rebury and cage.

Plan was on 12/12 to remove all live hatchlings and take them to warmer waters offshore. Unfortunately that plan was changed to waiting for another week.

12/17-

Found 15 of 20 live hatchlings had passed, also found 2 of viable eggs had hatched. No live hatchlings found .

Put remaining viable eggs back in nest



12/31 final inventory- 8 hatched eggs found at inventory appears all emerged from nest on their own


Nest 69 taught us a valuable lesson , that cooler to cold temps don't kill eggs and hatchlings. Just slows development.
