| Summary: | Microbial pathogens in recirculating aquaculture and egg incubation systems can cause elevated mortality and decreased production. Peracetic acid (PAA) is an effective disinfectant; however, its toxicity to early life stages of Atlantic salmon (Salmo salar) has not been assessed. This research determined the 24-hour LC50 value of PAA for three early life stages of Atlantic salmon: eyed eggs, fry, and fingerlings. Toxicity Relationship Analysis Program (TRAP) LC50 values for eggs treated for 5 and 10 minutes were 781.5 mg/L and 485.0 mg/L PAA, respectively. Trimmed Spearman Karber (TSK) LC50 values for eggs treated for 5 and 10 minutes were 771.1 mg/L and 462.1 mg/L PAA, respectively. TRAP LC50 values for fry and fingerlings were 4.0 mg/L and 5.3 mg/L PAA, respectively. TSK LC50 values for fry and fingerling were 4.1 mg/L and 5.3 mg/L PAA, respectively. These LC50 values provide guidance for developing safe PAA treatment protocols for Atlantic salmon eggs, fry, and/or fingerlings. ... |
