“…This shows that each type of fish has a different tolerance to clove oil (Fernandez et al, 2017). According to Wojan et al, (2019) The use of anesthesia using either clove oil or MS-222 can cause discoloration of the fish's body. In fish that were given anesthesia, there was a difference in color compared to the control, there was an increase in saturation and a decrease in brightness.…”

This study aims to determine the effect of clove oil concentration and time of immersion in clove oil on the anesthesia, recovery time, and physiological responses in the payangka fish (Ophieleotris aporos). The experimental design was completely randomized with a 6 x 3 factorial arrangement. The first factor was a concentration of clove oil consisting of six levels i.e., 0.02; 0.03; 0.04; 0.05; 0.1, and 0.2 ml/L of water. The second factor was a time of immersion consisting of three levels i.e., 1; 3; and 6.5 hours. Results showed that the concentration of clove oil significantly (p<0.05) affected the anesthesia time and the recovery time after immersing. The length of immersing and concentration of clove oil also significantly (p<0.05) affected the concentration of glucose, but not significantly (p>0.05) affected the concentration of cholesterol. It showed that clove oil can be used as anesthetization for payangka fish in the appropriate dose. The optimal concentration of clove oil that can be used as anesthesia for the transportation of live payangka fish is 0.02 ml/L of water. Meanwhile, for handling activities on payangka fish, a clove oil concentration of 0.03 ml/L of water is recommended

This study aimed to evaluate the effects of different concentrations of astaxanthin and Bidens Pilosa compound feed additives on the color and hypoxia tolerance of cherry shrimp (Neocaridina davidi var. red). Color parameters were assessed using CIELAB color space, and differential gene expression related to color and stress was analyzed using reverse transcription quantitative polymerase chain reaction (RT-qPCR) to understand the gene regulatory mechanisms affecting color expression and stability. Over a 56-day rearing period, the feed additives AX100 (astaxanthin 100 mg/kg) and AX100+BP (astaxanthin 100 mg/kg + B. pilosa 5 g/kg) significantly reduced the color difference values compared to the standard sample (ΔE*ab), indicating notable color boosting effects. This included a reduction in lightness (L*), a decrease in color hue angle (h*) with AX100, and an increase in redness (a*) and chroma (C*) with AX100+BP. We further designed 22 color-related gene primers, 16 of which amplified the target fragment. Six gene sets exhibited significant differences among all feed treatment groups and were correlated with color expression. After 9 hours of hypoxic stress, body color remained stable in the feed additive groups, especially in the AX100 + BP and AX200 + BP (astaxanthin 200 mg/kg + B. pilosa 5 g/kg) groups, with color differences before and after hypoxic stress remaining below the discernible threshold of the human eye, indicating optimal color stability. Additionally, the CAT gene, among the stress-related genes that successfully amplified, showed significant differences among feed treatment groups and correlated with color stability based on color difference values. In conclusion, the composite addition of 100 mg/kg astaxanthin and 5 g/kg Bidens pilosa (AX100 + BP) was identified as the most effective treatment. This formulation significantly enhanced cherry shrimp color, evidenced by improved parameters such as decreased lightness and increased redness. Moreover, AX100 + BP demonstrated superior color stability under hypoxic conditions, with ΔE*ab values remaining below the discernible threshold of the human eye, highlighting its potential for maintaining optimal color during transportation. Offering a basis for enhancing the commercial value and reducing the sale risks of cherry shrimp.
