“…However, not all species adhere to the decrease in acute toxicity concentrations of CuSO with increased exposure. Hoseini and Nodeh (2012) reported the 24 and 48h-LC 50 were both 0.42 mg L − 1 for Rutilus rutilus caspicus fry.…”

“…The toxic effects of formalin in fish include mortality and are directly proportional to the concentration (Table 1). However, tolerance to formalin varies among fish depending on the species, size (age), treatment conditions (Chmelova et al, 2016; Cruz et al, 2005; Cruz‐Lacierda et al, 2012; Fajer‐Ávila et al, 2003; Hoseini & Nodeh, 2013; Hoseini et al, 2013; Intorre et al, 2007; Neves et al, 2020; Tancredo et al, 2019), among other factors. Therefore, the toxicity of this chemotherapeutic to each fish species must be determined before application, and the data of toxicity and safe ranges of the dose of formalin can be extrapolated for fish farming.…”

The search for more effective methods and drugs to control parasites in fish farming is constant. Several studies have evaluated the effects of formalin in freshwater and marine fish and their parasites. Thus, this paper focuses on the major toxicological aspects of this chemotherapeutic including growth performance, histopathological damages, haematological and biochemical alterations, and antiparasitic efficacy. Acute toxicity (LC50—96 h) to formalin sulphate vary widely among fish species (0.1–640.0 mg/L) depending on various factors, as many fish species are sensitive to concentrations near those required for controlling and treating parasites. The toxicity of formalin on some metabolic processes leads to disturbances and imbalances to various physiological functions, particularly respiration and haematological and biochemical processes, due to histopathological damages in gills and haematopoietic organs. Formalin often affects the gills, liver, kidney and spleen, and in the gills provokes an increase in mucus and chloride cells, hyperplasia and/or hypertrophy of lamellae and epithelial lifting. Formalin used in therapeutic baths is extremely effective against various protozoan and monogenean species, which are parasites that infect gills, skin and/or fins of farmed freshwater and marine fish.

“…Fish treated with excessive formalin die because of formalin‐induced gill damage including epithelial division, denaturation, and hardening of gill tissue protein that interrupt osmoregulation and gas exchange (Cruz and Pitago ; WendelaarBonga ). Because the intensity and lethality of gill damage vary with species, size, and metabolism, as well as salinity in some cases (Hoseini and Nodeh ), it is necessary that the tolerance of the fish be empirically assessed for each species. Present results suggest that LC 50 of formalin for S. rivulatus juveniles (551.0 mg/L) is greater than LC 50 of formalin for many marine teleosts, such as Florida pompano, Trachinotus carolinus , LC 50 = 69 mg/L (Birdsong and Avault ); Atlantic salmon fingerlings, Salmo salar , LC 50 = 69 mg/L (Bills et al ); American eel, Anguilla rostrata , LC 50 = 81 mg/L (Hinton and Eversole ); striped bass fingerlings, Morones axatilis , LC 50 = 10.8 mg/L (Reardon and Harrel ); and bulls eye puffer fish, Sphoeroides annulatus , LC 50 = 79 mg/L (Fajer‐Ávila et al ); and thus formalin can be used as a prophylactic or treatment for this species.…”

As aquaculture evolves from extensive pond culture to intensive tank and cage systems, chemical dips and baths are increasingly being used to treat a concomitant increase in ectoparasitic and bacterial infestations. Some of the main disease‐causing agents are ectoparasites on the skin and gills of fish. Consequently, application of chemotherapeutics is increasing in aquaculture industries in order to control outbreaks of parasitic infestations. However, the toxic effect of commonly used chemotherapeutic agents on specific aquacultured fish species is often unknown. The present work was performed to test the effect of four commonly used chemical treatments on rabbitfish, Siganus rivulatus. The lethal concentrations for 50% of population (LC50) of formalin, copper sulfate, potassium permanganate, and hydrogen peroxide for S. rivulatus juveniles treated for 1 h were assessed. Formalin and potassium permanganate tolerance values were determined by calculating 72‐h LC50 values through probit analysis. The 72‐h LC50 values for the formalin toxicity tests were 551.0 and 1.68 mg/L, respectively. LC50 of copper sulfate and hydrogen peroxide could not be determined from the concentrations tested but were found to be >3 and >700 mg/L, respectively. Accordingly, treatment concentrations of formalin and potassium permanganate used for other fish species could be lethal to S. rivulatus, but the species appears to be quite tolerant to copper sulfate and hydrogen peroxide.
