What apparatus is used to artificially hatch eggs?
Aldabra giant tortoise of eggs in a year. After incubating for about eight months, the tiny, independent young hatch between October and December. In captivity, oviposition dates vary. Tulsa Zoo maintains a small herd of Aldabra tortoises and they have reproduced several times since 1999. One female typically lays eggs in November and again in January, providing the weather is warm enough to go outside for laying. The zoo also incubates their eggs artificially, keeping two separate incubators at 27 °C (81 °F) and 30 °C (86 °F). On average, the eggs kept at the latter temperature hatch in 107 days. The Aldabra
Egg hatch assay Egg hatch assay Egg hatch assay (EHA), also called an egg hatch test (EHT), is a method used to determine a given parasite's resistance to extant drug therapy. Fresh eggs are incubated from the parasite of interest and serial dilutions of the drug of interest are applied. The percentage of eggs that hatch or die is determined at each concentration and a drug response curve may be plotted. The data can then be transformed and analysed to give further statistics such as an effective dose. This technique is labour-intensive, expensive and can take some time, however an egg hatch assay
