To overcome excess residues and fish mortality rates during transportation, natural ingredients, namely clove oil, can be used. Compounds in clove oil are considered safe because they use natural ingredients. The purpose of this study was to determine the effectiveness of using clove oil as an anesthetic agent with different doses on the length of time of unconsciousness and survival rate of tilapia. This research was conducted from May to June 2023. This research was carried out at the Bungus Fish Seed Center, Padang, and West Sumatera. The method used in this study is the experimental method. The design used in this study was a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatment used in this study is use of clove oil with different doses. Treatment A1 = 0.5 ml L-1 water, A2 = 1 ml L-1 water, A3 = 1.5 ml L-1 water and A4 = 2 ml L-1 water. Observations of changes in tilapia behavior and water quality were analyzed descriptively, while the length of time of stupor and survival of tilapia obtained during the study were analyzed using analysis of variance (ANOVA). To see the differences between treatments, the Duncant Multiple Range Test (DMNRT) was performed. Data is processed using the SPSS 26 program. The conclusion that can be considered in this study is that the administration of clove oil with different doses as an anesthetic has a significant effect on the longest induction time, on the length of time the fish were unconscious, the length of time the fish regained consciousness and survival rate of tilapia. In treatment A2 with a dose of 1 mL L-1 of water, it was optimal to stun tilapia for 244 minutes with a survival of 88.89%.Keywords:Clove oilFish transportationTilapia

Ectoparasites pose a significant threat to the health and productivity of vaname shrimp (Litopenaeus vannamei) in aquaculture settings, particularly in tropical regions. This study aimed to assess the prevalence, intensity, and dominance of ectoparasites in vaname shrimp ponds in Padang Pariaman, West Sumatra. This study was conducted from March to May 2024 in vaname shrimp ponds in Padang Pariaman, West Sumatra. Sampling was carried out at five different pond stations, and water quality assessments were carried out. Ectoparasites were identified, and their prevalence, intensity, and dominance were measured. Station II had the highest prevalence (100%), intensity (69 ind/shrimp), and dominance of ectoparasites from all other observation stations. The dominant types of ectoparasites were Epystylis sp. (37.81%), Zootamnium sp. (18.65%), and Vorticella sp. (20.64%). Water quality at five Vaname shrimp pond stations showed significant variations, especially in pH, COD, and ammonia parameters, with some values exceeding the quality standard. Station V was identified as the most critical location with the highest COD (90.08 mg/l) and ammonia (0.188 mg/l) values and pH below the optimal threshold. It is important to implement better pond management strategies to improve shrimp health and productivity while minimizing the ectoparasites on aquaculture systems in tropical regions.Keywords:Vaname shrimpEctoparasitesAquaculture managementWater quality

This research is scheduled to take place from May to August 2022 at the Marine and Brackish Water Aquaculture Fisheries Center in West Sumatra. The method employed will be observation, which entails monitoring the eating behavior of lobsters and their feeding schedule every time food is provided within a 24-hour timeframe. Data pertaining to lobster eating behavior will be analyzed descriptively based on these observations. Throughout the research, various feeding activities of sand lobsters were documented. The observational results indicated that the lobster feeding process remained consistent. The lobster typically initiates the process by gripping the food with its claws and feet, subsequently breaking it into smaller pieces with its claws, and then placing these fragments into its mouth. As the lobster tears apart the food, the next step involves transferring it to the mouth using the nearest upper and lower jaws. In light of this research, it can be inferred that lobster feeding behavior encompasses the following steps: firstly, the lobster approaches the food after spotting it; secondly, lobsters employ their claws to grasp the food; and finally, lobsters tear and ingest the food. Lobster feeding activities are most commonly observed between 6:00 PM - 10:00 PM and 10:00 PM - 2:00 AM.Keywords: eating behavior; lobster; Lobster feeding schedule.
