“…Aqueous rosemary extract at a dose of 100 g/L for 30 minutes decreased the intensity of Dactylogyrus minutus in carps compared to water immersion [6]. Apart from its anti-leech properties, rosemary can also increase immunity in fish; the essential oil in rosemary used in feed can improve haematological parameters and increase the young beluga's immunity [7]. Bathing rosemary to control sea leech infections in grouper fish can be considered.…”

One common disease that attacks hybrid grouper is marine leech (Zeylanicobdella sp.). Therefore, it is necessary to take safe and environmentally friendly treatment steps, namely bathing fish infected with marine leeches with rosemary solution. This research examined the application of rosemary solution with different concentrations and bathing times to decrease the intensity of marine leech infections in “cantang” hybrid grouper (Epinephelus fuscoguttatus x Epinephelus lanceolatus). The experimental design of this research was a randomized factorial design (rosemary solution concentration factor and bathing time factor) with three replications. This experimental’s treatments were a combination of rosemary solution concentrations (0, 7.5, and 15 mL/L) and bathing times (20, 40, and 60 minutes). The experiment showed that the interaction of concentration and bathing time of rosemary significantly eliminate the number of leeches in “cantang” hybrid grouper. The rosemary solution at concentrations of 15 mL/L and 7.5 mL/L significantly differed from the control; 15 mL/L was the best concentration for reducing leeches intensity, with an average intensity reduction of 29.91%. The best duration of bathing rosemary to decrease the intensity of leeches in “cantang” hybrid grouper is 60 minutes, with an average reduction in intensity of 19.21%. However, the concentration and duration of bathing in rosemary solution could not decrease the prevalence of leeches in “cantang” hybrid grouper. Bathing grouper fish in rosemary solution at a dose of 15 mL/L for 60 minutes is the best treatment to decrease the intensity of leech attacks on grouper fish by 44.85%. Bathing hybrid grouper with rosemary solution is one solution to decrease the intensity of marine leech attacks on fish farming.

One of the diseases that attacks and disrupts productivity in hybrid grouper cultivation (Epinephelus fuscoguttatus >< Epinephelus lanceolatus) is caused by the sea leech parasite (Zeylanicobdella sp.). To control parasite attacks, safe and easy control measures need to be taken, one of which is the application of turmeric juice to soak fish infected with leeches. Therefore, research must be conducted to test the most effective concentration and soaking time of turmeric (Curcuma domestica) juice to reduce the intensity of sea leech attacks on hybrid grouper fish. This study was to test differences in turmeric juice concentration using a completely randomized factorial design consisting of 2 factors, namely the turmeric juice concentration factor (0 mL/L, 0.6 mL/L, 0.9 mL/L and 1.2 mL/L seawater) and immersion time factor (30 and 60 minutes) with eight treatments and three replications. The research results showed that the most effective reduction in intensity after soaking with turmeric juice was at a concentration of 1.2 mL/L of seawater for 60 minutes at 24.00%. The interaction between the concentration and soaking time of turmeric juice reduced the intensity of parasites but did not affect the behaviour and survival of the fish. Turmeric juice has the potential as an anti-leech and can be applied in grouper cultivation to reduce the intensity of leech infections.
