Fisherman Watch presents by "Fish Planet" give an accurate prediction of success on fishing and addressed to all fishermen and amateurs, and anglers sportsmen. The program displays the influence of weather and movements of the sun and moon on the result of fishing on selected species of fish and allows you to choose the best hours for fishing.

After that, to this point information is calculated sunrise, sunset and the culminations of the sun and moon, high tide and low tide - if the point is located in the coastal zone. Then, in accordance with these seasonal-diurnal model of the behavior of fish MathFish5.1(TM) - is detecting the influence of all these parameters for each of fish. It is important that for the different species of fish these effects are also accounted differently. For each fish You want to catch, have the best time, this time is determined by the mathematical model accurately defined biologists parameters. Similarly, the influence of the tide on coastal fishing fish species, which is not affected, in contrast to the height of the moon above the horizon, on catching fish in inland waters.

To better reflect the influence of climate on the World map is built the model of climatic zones taking into account details of the relief and global currents. For for more convenient display you can select the desired fish species. In the application settings the fishs are distributed across the families. In the basic free version of the app included 3 fish. Regional packages are separately available for download: North America - 76 species; Europe and Asia - 151 species; Marine fish - 322 species.
