Sri Vijaya Puram, Jan 24: Mr. C. Arjun, a resident of Sri Vijaya Puram, initiated a freshwater ornamental fish culture startup in 2021, initially importing 50 varieties of commercially important ornamental fish from Chennai. However, the venture encountered substantial challenges, notably a concerning mortality rate of 70–80% among the newly imported fish, attributed to deficient management practices, and limited knowledge of disease prevention and treatment protocols.
