Abstract：Acute toxicity of strong glutaral solution ,sodium periodate ,bromochlorohydantoin ,sodium hy‐pochlorite ,benzalkonium bromide and trichloroisocyanurie acid to golden pompano T rachinotus ov atus with body weight of (4 .3 ± 0 .5) g ,were studied in seawater filtered by sand ,at a pH of 8 .02—8 .37 ,dis‐solved oxygen level of above 6 .0 mg/L ,a salinity of 20—24 and water temperature of (29 .0 ± 2 .0) ℃ u‐sing 96 h static bioassay test .The results showed that the 24 h LC50 was 3 .519 mg/L in trichloroisocyanu‐rie acid ,14 .166 mg/L in strong glutaral solution ,0 .092 mg/L in sodium periodate ,6 .448 mg/L in bromo‐chlorhydantoin .2 .156 μL/L in sodium hypochlorite ,and 9 .806 μL/L in benzalkonium bromide ;The 96 h LC50 was 3 .434 mg/L ,12 .936 mg/L ,0 .083 mg/L ,and 6 .150 mg/L ,1 .981 μL/L ,8 .756 μL/L ;with the safe concentration of 0 .981 mg/L ,4 .018 mg/L ,0 .025 mg/L ,1 .812 mg/L ,0 .529 μL/L ,and 2 .666 μL/L .T he findings indicate that trichloroisocyanuric acid ,strong glutaral solution and bromochlorohydantoin are used safely in prodution ,but sodium periodate ,sodium hypochlorite ,benzalkonium bromide should be used caref ully .
