Aeromonas hydrophila as a causative agent of blue sac fry syndrome in different trout species

Abstract

Blue sac fry syndrome (BSFS) occurs in alevins of rainbow trout Oncorhynchus mykiss (Walbaum) and brook trout Salvelinus fontinalis, (Mitchill) and can cause substantial losses during the incubation period. It is generally considered to be a non-infectious disease associated with water quality criteria such as temperature, pH, total nitrogen compounds and dissolved gasses (Noga 2010).
