“…Numerous early studies suggested that natural products (compounds and extracts) derived from some medicinal plants have potential to be used for prevention and control against Saprolegnia (Gormez and Diler 2014; Huang et al ) found that Magnolia officinalis exhibited enhanced growth inhibition and could therefore be a valuable antifungal herbal species. Gormez and Diler () evaluated the in vitro antifungal activity of essential oils extracted from Tymbra , Origanum , and Satureja species on S. parasitica , and suggested that these essential oils have the potential to be used against S. parasitica infection in rainbow trout ( Oncorhyncus mykiss ).…”

“…There are few comparable data in the literature of rhein, but these findings support that rhein shows promising anti-Saprolegnia properties that could be exploited as a fungicide in the prevention and control of Saprolegnia infection, while its 48 h-LC 50 to the host (grass carp) was determined to be 148.5 mg/L which indicated the safety for use of rhein for this purpose.

Saprolegnia infections cause severe economic losses among freshwater fish farming. In this study, two known compounds, rhein and aloe‐emodin, were isolated from Rheum palmatum, and the in vitro inhibitory activity of both compounds against mycelial growth and spore germination of Saprolegnia was tested. Both rhein and aloe‐emodin were able to decrease Saprolegnia mycelial growth and spore activity in all tested concentrations after exposure for 48 h. Complete inhibition of mycelial growth was observed at 20 mg/L for rhein and at 50 mg/L for aloe‐emodin, while spore germination was 100% prevented at 16 and 40 mg/L for rhein and aloe‐emodin, respectively. Because rhein showed stronger in vitro anti‐Saprolegnia activity, it was further tested in vivo to measure the prevention and treatment efficacy on Saprolegnia infection of grass carp. Its acute activity to grass carp was also evaluated. The results revealed that exposure to rhein at 20 mg/L for 7 d could prevent 93.3% of infections by Saprolegnia in abraded grass carp, while 67.7% of infected fish could be recovered by treatment with rhein. The 48‐h median lethal concentration (48 h‐LC50) to grass carp was 148.5 mg/L, which is about 7.4 times the effective dose indicating the safety for the use of rhein. This study suggests that rhein has promising anti‐Saprolegnia activity and may be an option in preventing and controlling Saprolegnia infection.

“…() observed that MIC values of O. vulgare , T. vulgaris and S. montana were 100 μL mL −1 , 100 μL mL −1 , 200 μL mL −1 , respectively and all plants had a fungicidal activity at 200 μL mL −1 . Gormez and Diler () noted that MIC values of the essential oils of O. onites, S. tymbra and T. spicata for S. parasitica strains were 10 μL mL −1 , 100 μL mL −1 and 50 μL mL −1 respectively.

“…Several studies about the use of plant extracts against pathogenic fungi have been observed that some essential oils are capable of inhibiting the growth or even causing the death of S. parasitica at comparatively low concentrations (Khallil ; Tampieri, Galuppi, Carelle, Macchioni, Cioni & Morelli ; Sharif Rohani, Ebrahimzadeh Mosavi, Khosravi, Baba, Bahonar, Mirzargar & Mehrabi ; Udomkusonsri, Trongvanichnam, Limpoka, Klangkaew & Kusucharit ; Pirbalouti et al . ; Gormez & Diler ).

In the present study, the chemical composition and the antifungal properties against Saprolegnia parasitica (in vitro and in vivo) of the essential oils of thyme (Satureja cuneifolia) from Mediterranean region of Turkey were evaluated for the first time. The composition of oils was analysed using gas chromatography/mass spectrometry (GC/MS). The major constituents of oil of S. cuneifolia were cavracrol (46,84%) and cymene (16.90%). Antifungal effects of S. cuneifolia essential oil against S. parasitica strains (A1 and E1) were detected by disc diffusion and tube dilution assays. The antifungal effect of S. cuneifolia was determined to be stronger against S. parasitica E1 isolate (MIC 50 lL mL À1 , MLC 250 lL mL À1 ) compared with S. parasitica A1 isolate (MIC 50 lL mL À1 , MLC 500 lL mL À1 ). Following in vitro assays, effective doses of S. cuneifolia for disease control in rainbow trout eggs experimentally infected with S. parasitica were investigated. For this aim, infected eggs were treated with the essential oil (0, 5, 10, 20 and 50 ppm) during incubation period (21 days) after fertilization. Formalin (5 mL L À1 ) was used as positive control. Hatching rate of eggs at the end of incubation period were calculated. The highest hatching rates were recorded in S. parasitica E1 strain at 5 and 10 ppm concentrations of S. cuneifolia and in S. parasitica A1 strain at 10 and 20 ppm (P < 0.05).

Plants have been reported to produce various effects such as antistress, growth promotion, appetite stimulation, immunostimulation, aphrodisiac and to have antipathogen properties in fish and shrimp aquaculture due to their varied active principles such as alkaloids, terpenoids, tannins, saponins and flavonoids. To date, most scientific studies on the use of medicinal plants in aquaculture have focused on identification of biological activity rather than natural product determination. The plant species that have displayed the highest potential for use in aquaculture are garlic (Allium sativum), pomegranate (Punica granatum), bermuda grass (Cynodon dactylon), Indian ginseng (Whitania somnifera) and ginger (Zingiber officinale). Algae are considered to be a rich source of original bioactive molecules which display multiple bioactivities. In aquaculture, several recent studies have showed the potential of algae for the treatment of pathogens or to improve fish fitness.
