Artificial Incubation, Hormonal Sex Reversal Promoted Tilapia Boom
Research And Development Expansion of tilapia farming on a commercial scale was hindered by the limited availability of quality fry realized by researchers. Attempts were made to develop a practical technique of massscale fry production at the Asian Institute of Technology (AIT) in Klong Luang, Pathumthani, Thailand. A series of onstation trials were conducted over a decade, maintaining the Chi...
متن کاملFactors related to shell deaths during artificial incubation of ostrich eggs.
The ostrich industry experiences a high rate of embryonic mortalities during artificial incubation of eggs. Embryonic deaths were studied from data recorded on 37,740 fertile eggs incubated artificially during the 1998-2005 breeding seasons. Roughly 10,000 eggs that sustained embryonic mortalities were classified according to the stage and nature of death, i.e. before 21 days of incubation, aft...
متن کاملSurvival and Growth of American Alligator (Alligator mississippiensis) Hatchlings after Artificial Incubation and Repatriation
—Hatchling American Alligators (Alligator mississippiensis) produced from artificially incubated wild eggs were returned to their natal areas (repatriated). We compared artificially incubated and repatriated hatchlings released within and outside the maternal alligator’s home range with naturally incubated hatchlings captured and released within the maternal alligator’s home range on Lake Apopk...
متن کاملArtificial incubation of Muscovy duck eggs: why some eggs hatch and others do not.
This study was designed to gain insight into the influence of spraying and cooling, during artificial incubation, on the embryo metabolic rate and hatching ability of Muscovy duck eggs. Three times a week 93 incubated eggs were sprayed and cooled for 0.5 h at room temperature. Daily embryo metabolic rate was measured in 30 eggs with a water vapor conductance ranging from 1.15 to 2.07 mg/day-kPa...
متن کاملIncubation effects
After an initial period of unsuccessful work at solving a problem, a subject might either continue to work uninterruptedly or put the problem temporarily aside, returning to it later. The elusive laboratory phenomenon called "incubation" refers to superior performance for those subjects who return to the problem after a delay rather than working continuously on the problem. The forgetting-fixat...
