The Norwegian government wants to start puncturing the unhatched eggs of Canadian and grey geese to control the geese population. |
Additionally, we examined unhatched eggs for evidence of embryo development, and, if present, collected tissue samples. |
Water circulating around the spawning bed carries oxygen to the eggs, but when silt covers them, the unhatched fish are suffocated. |
The hatch rank of unhatched eggs was deduced from their volume, and the ranks of successfully hatched young were adjusted accordingly. |
All along the beach feral dogs have raided turtle nests and eaten the unhatched eggs. |
Eggs were candled at 13 days, and unhatched eggs at 20 days of incubation were opened to allow classification of down color. |
