Abstract

Jungga lime (Citrus jambhiri L.)/Sundai acid/Limau kuit is a natural ingredient that contains alkaloids, saponins, steroids, tannins, flavonoids, ascorbic acid, essential oils, and limonene, which are antibacterial. This research was conducted from August to December 2024 at the Laboratory of Fish Diseases and Parasites, Faculty of Fisheries and Marine, Universitas Riau. This research aimed to analyze the physiological and biochemical responses of the blood of striped catfish. The method used was experimental with a completely randomized design (CRD) of 1 factor, five treatments, and three replicates. The treatments applied were Kn (without the addition of jungga lime and without being infected with A. hydrophila), Kp (without jungga lime and infected with A. hydrophila), and jungga lime-enriched pellets at P1 (6.0 mL/kg), P2 (6.5 mL/kg), and P3 (7.0 mL/kg), and infected with A. hydrophila. Striped catfish (P. hypophthalmus) with a size of 8-12 cm and a weight of 6-7 g were kept in a 54x37x29 cm container, with a stocking density of 1 fish/3 L, and fed 3 times a day and sanitation. On day 32, fish were intramuscularly challenged with A. hydrophila (108 CFU/mL) at 0.1 mL. The results showed that the best dose was P3 (7.0 mL/kg) with a blood glucose of 79.33 mg/dL, Mg 3.07 mg/dL, Ca 9.87 mg/dL, P 4.03 mg/dl, Lisozyme activity of 259 units, mL, weight growth reached 19.11 g, and length growth reached 5.39 cm. Adding jungga lime to fish feed can improve post-challenge fish blood's physiological and biochemical responses

Abstract

Trichogaster trichopterus Pall is a freshwater fish widely found in Indonesian waters, particularly in the swamp areas of Riau Province. This study was conducted from September 2024 to March 2025 at the Laboratory of Fish Parasites and Diseases, Faculty of Fisheries and Marine Science, University of Riau. The objective of this research was to analyze the intestinal tissue structure of T. trichopterus infected with Clinostomum sp. The methods used were purposive sampling and survey techniques. Fish samples were collected from the reservoir at the Faculty of Fisheries and Marine Science, University of Riau. Sampling was conducted three times over 30 days at four predetermined stations. Station I was located at the reservoir entrance, Station II to the west, Station III to the north of the entrance, with a 50-meter distance between stations, and Station IV was located upstream. The research procedures included sampling, intestinal organ fixation in formalin, and preparation of histopathological slides through a series of stages: dehydration, alcohol removal, infiltration, embedding, sectioning, staining, and mounting. Observed parameters included clinical symptoms and intestinal histological structure, which were analyzed descriptively. The results showed that the intestines of infected fish exhibited alterations, including epithelial lifting, goblet cell proliferation, oedema, hypertrophy, haemorrhage, inflammatory cell infiltration, and necrosis. The histopathological index of infected fish intestines reached a damage score of 7, categorised as severe. Based on the findings, it can be concluded that Clinostomum sp. infection causes significant alterations to the intestinal structure of T. trichopterus

Abstract

The Mundam Jaya Joint Business Group (KUB) in Mundam Village, Medang Kampai District, Dumai City, participated in a community service program introducing the cultivation of Azolla sp. as a local feed source to improve the efficiency of Nile tilapia farming. The program aimed to reduce production costs, enhance productivity, and strengthen food security and the local coastal economy. The methods implemented included training, field practice, mentoring, and continuous monitoring and evaluation using a learning by doing approach. The results demonstrated that group members were able to master Azolla cultivation techniques, from propagation to its application as supplementary feed for tilapia. The use of Azolla reduced dependence on commercial feed, lowered feed costs by up to 45%, and improved tilapia growth and survival rates, with survival exceeding 85%. Beyond technical outcomes, the program also enhanced participants’ business management skills, particularly in production record-keeping and marketing strategies. Overall, this initiative proved that the utilization of natural resources such as Azolla as fish feed can serve as a sustainable innovation in aquaculture. It not only supports the development of the village aquaculture sector but also contributes to economic independence and food security for coastal communities.
