Built forecast catch smallmouth bass, pike, perch, bream, carp, crucian carp and other fish species. Application via the Internet receives weather at the point of location of the mobile phone. It records the values of atmospheric pressure, temperature, humidity, wind, clouds and the dynamics of all these parameters. 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. The user can choose what factors he considered when forecasting.With the help of the switches that are on the screen, you can disable the influence of the Sun, moon, tides, weather and even the daily behaviors of the selected fish species. In this case, will stay only the data of seasonal behavior of fish for those coordinates where is the phone. Itself the seasonal model, depends on the coordinates of the fisher. 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.
