Tag my Fish is a project useful for anglers, ichthyologists, and ecologists. It will present, unite and connect all fish species with all body waters in one place, both in the context of sport fishing and in the context of ecology and protection of waters and aquatic ecosystems.

The site has two separate, but closely related parts: the first, of a scientific-educational type, showing fish species and waters, and the second, which relies heavily on the first, and which is a social network for anglers. It will aim to gather millions of anglers who will upload photos of their catches and tag the water on which they made their catch and the type of fish they caught. If they tag the fish species incorrectly or simply do not know what they have caught, the system will automatically re-tag the catch and select the right fish species as soon as possible.

This database will be unique in the world and will be characterized by very high accuracy. As such, it will allow the angler to get very valuable information that will help him decide where to go fishing and what kind of fish to catch. The application will be welcome on domestic fishing grounds, and especially useful when the fisherman is fishing in lesser-known waters in the country or abroad.

The project will also have great ecological importance. By monitoring catches, one can also monitor the health of the ecosystem. This way, ecologists will be able to find waters where rare and endangered fish species, such as tench and crucian carp, and, if necessary, additionally protect those waters and fish populations. They will be able to use the application for early detection of invasive fish species and act quickly and preventively to reduce the chances of those species spreading further. They will be able to find even points on the river downstream from which the number of catches is drastically decreasing and to mark those points as a potential inflow point of some toxic wastewater or chemicals used in agriculture. Or, without going out on the field, to scientifically prove how many times the population of some fish species in mountain rivers has been reduced due to redirection the part of water into the pipelines of hydroelectric power plants.

The current version of the project is 2.0, that includes a social network.

The social network was officially launched on September 25, 2023.
