A comprehensive review of major viral, bacterial, oomycete, and parasitic diseases affecting warmwater freshwater finfish, highlighting diagnostics, prevention, and climate change impacts.
Freshwater finfish aquaculture accounted for over 53.4 million tonnes (43.64% of total global aquaculture production) in 2020, with cyprinids, tilapias, and catfishes representing the vast majority of volume. This chapter provides a comprehensive review of key infectious diseases impacting warmwater freshwater finfish in pond and cage culture systems. Major viral pathogens examined include Tilapia Lake Virus (TiLV), Tilapia Parvovirus (TiPV), Carp Edema Virus (CEV), Koi Herpesvirus (KHV), Grass Carp Reovirus (GCRV), and Channel Catfish Virus (CCV). Key bacterial diseases discussed comprise motile Aeromonas septicaemia (MAS), Pseudomonas septicaemia, Edwardsiellosis, Francisellosis, Columnaris disease, and Streptococcosis caused by Streptococcus agalactiae and S. iniae. In addition, water moulds (Saprolegnia, Aphanomyces invadans) and prominent parasitic taxa—such as ciliates (Ichthyophthirius multifiliis, Trichodina), dinoflagellates, myxozoans, monogeneans (Dactylogyrus, Cichlidogyrus, Gyrodactylus), and crustacean ectoparasites (Argulus)—are detailed with respect to pathology, diagnostics, and biosecurity control strategies. Finally, the chapter assesses how climate change drivers, including rising temperatures and extreme weather events, exacerbate disease dynamics in key tropical aquaculture regions.

A comprehensive review outlining critical challenges, practical strategies, and policy frameworks like the Progressive Management Pathway (PMP/AB) to mitigate disease risks and enhance global aquaculture biosecurity.
First confirmation that pathogenic Vibrio parahaemolyticus (AHPND) can be aerosolised by pond aeration and carried over 70 m, identifying airborne transmission as a critical biosecurity risk in shrimp farming.
Water supplementation with a commercial Bacillus probiotic mixture in BFT and clear water systems significantly enhanced gut Bacillus colonization and suppressed Vibrio density in Litopenaeus vannamei.
