Abstract

The frequent use of synthetic antioxidant compounds can cause degenerative diseases, especially consumers, so that natural antioxidant compounds are needed to reduce the risk of disease. One of the biotas that may contain potential as natural antioxidants is sea cucumber. Sea cucumbers are marine invertebrates that have therapeutic properties whose bioactive content has the potential as antioxidants. Thus, this study aims to determine the potential of two species of sea cucumber (Stichopus variegatus and Holothuria fuscocinerea) as natural antioxidant candidates as an alternative to synthetic antioxidants by knowing the bioactive content and analyzing the antioxidant activity of the sample. The research was started from April 1 to September 29, 2021 with methods including sampling in the waters of the Thousand Islands National Park, extraction, antioxidant testing, testing for total compound content, and data analysis on sample extracts of S. variegatus and H. fuscocinerea. The results of the DDPH antioxidant test and β-carotene bleaching assay after the one-way ANOVA test showed that the antioxidant activity value was P < 0.05, which means that there was a significant difference in sample concentration on antioxidant activity. In the method and -carotene bleaching assay, the sample extracts of S. variegatus and H. fuscocinerea were 46.37% and 45.75%, respectively. Based on the value of the antioxidant test results and bioactive content, it can be concluded that the sample extracts of S. variegatus and H. fuscocinerea have very weak antioxidant activity so that they cannot be used as alternative natural antioxidants to replace synthetic antioxidants.

Abstract

An important component in the application of biofloc is the presence of probiotic bacteria as a floc-forming agent. This study aimed to analyze the differences in the yield of vannamei shrimp in a biofloc system using commercial probiotics and independent probiotics on a laboratory scale. The study design was a completely randomized design with 3 treatments and 4 replications, including independent probiotics (IP), commercial probiotics (CP) and control (C). PM utilized an independent formula with starter bacteria Lactobacillus casei and PK contained bacteria Bacillus sp., Pseudomonas sp., Nitrosomonas sp., Aerobacter sp., Nitrobacter sp. Probiotics were fermented 24 hours before its application to the maintenance medium. A total of 15 shrimp/aquarium measuring 3.29 ± 0.48 g were reared for 27 days after the floc was first formed. The results showed that the growth and feed conversion ratio of vannamei shrimp in the biofloc system were higher than that of the control (P<0.05). Growth and feed conversion ratio between probiotic treatments did not show significantly different results (P>0.05). Survival in treatment and control groups was not significantly different (P>0.05). The observed floc volumes which increased during the rearing of vannamei shrimp were up to 6.50-7.50 mL/L. Several types of organisms found in the flock included nematodes, phytoplankton, copepods and protozoa. The observed water quality was the same in each treatment except for higher dissolved oxygen and ammonia in the control. This study recommends the use of independent probiotics in vannamei shrimp culture based on biofloc technology.

Abstract

Depik Fish (Rasbora tawarensis) is an endemic fish species found in Tawar Lake, with a threatened status. Domestication efforts are being undertaken to conserve the Depik Fish population. This study aimed to analyze the effectiveness of different vitamins on the growth and survival of Depik Fish. The study was conducted at Balai Benih Ikan (BBI), Pegasing - Central Aceh Regency, from December 2021 to January 2022. A Complete Random Design (CRD) with four treatment levels and four replications was employed, including a control group and three experimental groups: 300 mg/kg feed of vitamin C, vitamin B complex, and Viterna Plus. The results of the Anova test indicate that the dosage of vitamin C, vitamin B complex, and Viterna Plus in commercial feed significantly influenced the absolute weight growth, absolute length growth, and specific growth rates of the Depik Fish (P<0.05). However, it did not have a significant effect on feed efficiency and survival. Duncan’s test revealed significant differences among the treatment groups, with the highest values observed in the application of Viterna Plus at a dosage of 300 mg/kg feed, which resulted in increased growth and survival of the Depik Fish. Therefore, the use of Viterna Plus in fish feed is recommended.

Abstract

Cryopreservation in red bader fish is needed for conservation and development of gamete cell storage. It is a chemical compound that can prevent cell or tissue damage due to freezing. In addition, dimethyl sulfoxide can penetrate cells quickly during equilibration. This research aimed to study reproductive biology and analyze the fructose ability as a extender in the Red Bader fish sperm cryopreservation process. The cryopreservation process was conducted at the Artificial Insemination Center, Singosari. The test fish were obtained from the Freshwater Cultivation Development Center, Umbulan then they were reared for 2 months to get the level of gonad maturity. This study was designed using a completely randomized design (CRD) which consisted of three treatments and three replications. The treatment given was the use of fructose extenders with different percentages i.e., 0.2%, 0.4%, and 0.6%. The results showed that the sperm characteristics of the red bader fish (Puntius bramoides) had a volume of 3.18 mL, a pH value of 7.39, a milky white sperm color, a sperm concentration of 3.5x109 cells/mL, a motility value of 81.67%, and a viability of 85 %. The best type of fructose extender with 0,6% dimethylsulfoxide concentration has a motility value of 38,33% post-cryopservation and 36,67% post-cryopreservation viability. The type of extender affects the sperm quality of angry bader fish during the cryopreservation process, the type of extender obtained was fructose with the best concentration of 0,6% dimethylsulfoxide with the highest motility and viability values.

Abstract

Phytomedicines are affordable, safe, and offer great potential for treating and controlling wounds. The effects of herbal supplements on Clarias gariepinus wound healing was investigated. Twenty-four fish (146.4±0.74g) randomised into four paired sub-groups: G1 and G2, G3 and G4, G5 and G6, G7, and G8 were fed formulated rations containing no herbal additive (0.0g/kg), 5.0g/kg of Allium sativum, 10.0g/kg of Chromolaena odorata and 10.0g/kg of Talinum triangulare as feed additive respectively at 5% body weight. On the 21st day, a sterile incision measuring 45.0 mm by 1.0 mm was made on the dorsolateral side of each fish. Subgroups G2, G4, G6, and G8 were intraperitoneally inoculated with 0.1 ml of pathogenic Pseudomonas aeruginosa that had been predetermined (1.4 x106 bacteria/ml), while G1, G3, G5, and G7 were not inoculated. Post-incision, macroscopic parameters (measurements), given as percentage healing rates on days 3, 6, 9, 12, and 15, were used to evaluate the wound closure. Data were analyzed using descriptive statistics and ANOVA at α0.05. On day 3, there were significant differences between the control and treatment groups in the healing pattern (P < 0.05). On day 15 post-incision, G7 had the best healing rate in both inoculated (86.7 percent) and uninoculated (100 percent) fish, while G1 had the lowest healing rate (0.0 percent) and maximum healing rate (64.4 percent), respectively. The findings indicated that Talinum triangulare at a concentration of 10.0 g/kg was the optimum feed additive for promoting wound healing in Clarias gariepinus.

Abstract

Viral Nervous Necrosis (VNN) and Vibriosis are contagious diseases that can affect grouper fish from the larval to adult stages and cause significant economic losses for farmers. The owner brought the sunuk grouper to BKIPM Mataram to determine the fish's health. Since the grouper arrived at the floating net cage, the owner reports it has sustained bodily injuries. The grouper is separated from the healthy fish and placed in the area where the sick fish are. During maintenance, the fish exhibits a decrease in appetite, wounds on the mouth, operculum, and body from the head to the tail, low mobility, and swimming upside-down. The physical examination revealed that the fish was swimming limply in an inverted position and had lesions on various body parts. According to virological and bacteriological laboratory tests, the sunuk grouper infected with Vibriosis and VNN can be affected by the condition of fish that have been sick since they first arrived. Also, stress, contact with infected fish, and a decreased appetite result in sunuk grouper contracting the disease. Due to a disease, a fish's immune system does not function optimally. This condition makes sunuk susceptible to several infectious diseases.

Abstract

Feed was the most important part in aquaculture. Not only affecting growth, but the feed also impacted the cultivation environment. Poor feeding management in the use of feed will have a negative impact on the cultivation process. The purpose of the research was to create a dynamic system model. In the model a systemized algorithm was structured that would assist cultivators in carrying out aquaculture activities and with this model, problems that occurred were immediately resolved. The dynamic system model was the method used in this research. This model was used to determine the optimization of feed use based on several variables that support the process of using the feed. In this research, the production of Oreochromis niloticus was 14 kg, the amount of feed used was 10 kg, which affects the increase in the amount of organic matter, which was 3626.4 g (total feces + uneaten feed) in 65 days cultivation period. The result showed that the total feed was connected with organic waste, namely total N, total P, total feces, and total uneaten feed. The results obtained from this research were then poured into a dynamic system and the results were found, namely the relationship between feeding and organic waste, namely linear or perpendicular. The design of this dynamic system model was expected to enable tilapia cultivators to develop aquaculture businesses that were more environmentally friendly, effective, and efficient.

Abstract

Increased intensive cultivation of Punten Carp (Cyprinus carpio L.) is quite profitable, but on the other hand, it can result in a decrease in water quality due to uncontrolled leftover feed. Poor water quality can cause fish to become stressed then susceptible to disease, one of which is Myxobolus koi parasite infestation. The purpose of this study was to determine the effect of immunostimulant treatment of whole protein Myxobolus koi spores on the blood profile of Myxobolus-infested punten carp. The method used was an experiment with two treatments, the treatment without Myxobolus koi spore whole protein (P0) and the treatment of commercial feed added with an immunostimulant from Myxobolus koi spore whole protein of 5 µg/kg feed (P1). The study was conducted for 28 days and observed on days 0, 7, 14, 21, and 28, including the calculation of the number of erythrocytes, leukocytes, leukocyte differential, and water quality as supporting data. The abundance of erythrocytes in fish treated with P1 (1.16x106 cells/mm3-2.44x106 cells/mm3) was higher than in fish treated with P0 (1.09x106 cells/mm3-1.55x106 cells/mm3). The abundance of leukocytes in fish treated with P1 (3.79x104 cells/mm3-11.31x104 cells/mm3) was higher than in fish treated with P0 (3.51x104 cells/mm3-6.58x104 cells/mm3). The results of differential observations of leukocytes in the P0 treatment found basophils (0.3-1.3%), neutrophils (12.3-21.5%), eosinophils (2.5-4.9%), lymphocytes (61.9-76.8%) and monocytes (3.8-6.3%). The results of differential observations of leukocytes in the P1 treatment found basophils (0.3-1.0%), neutrophils (10.7-19.9%), eosinophils (2.4-3.9%), lymphocytes (61.8-72.6%) and monocytes (3.9-5.4%).
