Our Mission

30 years ago we realized that the existing record data in specified literature is incomplete and the information exchange between scientists, commercial fishermen and sports fishermen is poor.

Therefore we are engaged in updating a database concerning the maximum size of freshwater fish. "World Records Freshwater Fishing" started as a compilation of the most important references worldwide from international networks. In the last years more and more angler and scientists from around the world send us accurate data and high quality photos for verification.

Fishermen and scientists have free access to a complete, precise, and up-to-date reference database. In 2012 we had the idea to develop this database towards a travel portal. This project should be financed by offering tour operators, camps, equipment manufacturers etc. the opportunity to present themselves to interested fishermen at the optimal time. In the meantime we need your donations.

In addition we work as consultants free of charge for

  • Discovery Channel / Animal Planet, series "River Monsters"
  • National Geographic Channel, series "Hooked: Monster Fish"
  • the "Megafishes Project" of the National Geographic Society / WWF
  • angling magazines
