Russian Fish is an Android application designed for anglers who are passionate about fishing in Russia. Developed by MP Fish, this free app serves as a comprehensive atlas and field guide to 160 different fish species that are commonly found in Russia.

The app features original color illustrations and black and white engravings for each fish, along with detailed descriptions of their symptoms, habitats, biology, and local names. The data used to compile the materials was sourced from scientific papers, ensuring accuracy and reliability.

One unique feature of the app is the fish calendar, which is created for each species based on the information provided in the encyclopedia. This can be accessed through the separate application, Fisherman MP-Fish.
