METHOD TO MONITOR DEVELOPMENT OF HYDROCOLES, FOR INSTANCE, STURGEONS, IN EARLY ONTOGENESIS Russian patent published in 2012 - IPC A01K61/00 

FIELD: agriculture.

SUBSTANCE: method includes measurement of water medium temperature, detection of caviar development duration in stages by comparison with indices in the form of schedules, which correspond to development of caviar at permanent temperature. Periodical sampling of caviar is carried out to identify typical nature of development and execution of piscicultural and ichthyopathological actions. Water medium temperature is measured discretely. Parameters of object development duration are determined for each temperature measurement and summed up. Produced parameters are compared with a schedule of a selected temperature axis optimal for this object with the help of correction coefficients that reflect ratio of total length of development under permanent temperature on the selected axis to the total duration of development under current temperature. Further a temperature criterion is identified, which is a sum of products of a current temperature (in degrees) by discrete time (in hours) and by a correction coefficient that reflects quality of the object development. Further to collect and process measurements in the automatic mode the produced data is introduced into a dispatcher program, which is installed into a temperature metre.

EFFECT: technology will make it possible to increase accuracy of detecting duration of hydrocoles development in stages and thus efficiency of biological process control in the medium with variable temperature mode.
