Peruvian researchers develop the first vaccine for Amazonian fish

Tridge summary

A team of researchers, led by Jefferson Yunis, is developing a vaccine to reduce the use of antibiotics in fish farming. The vaccine is being developed for species such as rainbow trout and Amazonian fish, and is currently in its second stage. The vaccine is created by studying disease-causing bacteria found in dead fish, which are then inactivated and used to protect the fish. The vaccine is expected to improve survival rates and reduce economic losses for fish farmers by combating main pathogens such as 'Yersinia ruckeri' and 'Weissella tructae' in trout, and 'Aeromonas hydrophila' in Amazonian fish.

In an interview for the program Always at Home, Jefferson Yunis, master and doctor in aquaculture, shared details about the development of an innovative vaccine for fish. This project, carried out together with other researchers, aims to reduce the use of antibiotics in fish farming through vaccination. The development of this vaccine is focused on regions such as Junín, Puno, Loreto and San Martín, specifically for species such as rainbow trout and Amazonian fish such as gamitana and paco. Currently, the project is in its second stage. Over the years, pathogens living inside fish have been combated through the use of antibiotics. However, it has been shown that over time, these bacteria stop responding to medications, so the use of antibiotics becomes only a short-term solution. In this way, vaccination, according to Yunis Aguinaga, is presented as the option that has provided the best results in the fight against these bacteria. This method not only improves and increases the ...
