One of the factors that reduce fish production and population is disease. This study aims to determine the various types of zoonotic endoparasites, prevalence, intensity, abundance, diversity index, relationship of fish length-weight, relationship length with the intensity of parasites, and the relationship between weight and intensity of parasites. This research was conducted at Kelan Beach, Bali from December 2018 to April 2019. The research used a descriptive method using purposive sampling for data retrieval. Endoparasites were found in 9 types, namely Cucullanus sp. (3 ind), Anisakis sp. (7 ind), Lecithochirium sp. (1 ind), Hamacreadium lethrini (6 ind), Helicometra sp. (1 ind), Siphoderina sp (7 ind). Trypanorhyncha (32 ind), Tetraphylidea (4 ind), and Acanthocephalus sp. (1 ind). Organs infected by endoparasites were stomach (34%), liver (3%), and intestine (63%). The highest prevalence obtained was Trypanorhyncha (37.5%). The highest intensity obtained was Hamacreadium lethrini and Cucullanus sp. about 3 ind / fish. The highest abundance obtained was Trypanorhyncha (80%). The diversity index was 1,583. The length and weight relationship of Red Snapper (Lutjanus sp.) shows isometric relationship after t-test. Long relationship with parasite intensity has a very low relationship with a velue (r) of 0,142. The relationship between weight and parasite intensity has a very low relationship with a velue (r) of 0,139. Based on 9 types of endoparasites found 1 type is zoonotic namely Anisakis sp. that cause Anisakiasis disease.

This research aims to determine the survival of Litopenaeus vannamei post larvae when challenged with various density of pathogenic Vibrio harveyi. The L. vannamei post larvae used in this study was obtained from Vannamei Broodstock Center BPIUUK, Karangasem Bali. This research was conducted for two months, from April to May 2018 in fishery laboratory, Faculty of Marine Science and Fisheries, Udayana University by using complete randomized experimental design with four different V. harveyi density and three times repetitions. The study showed that the higher density of pathogenic V. harveyi resulted on the lower survival of L. vannamei post larvae. The highest density of V. harveyi 107 CFU/mL in treatment D resulted on 53±5.77% post larvae survival, while treatment A as control without addition of V. harveyi was still has survival of 100±0.00% at the end of experiment. The density 105 CFU/mL of V. harveyi (Treatment B) seems able to be tolerated by L. vannamei post larvae since the shrimp was still have high survival at this V. harveyi density. Further both V. harveyi density of 106 CFU/mL and 107 CFU/mL were not able to tolerated by the shrimp post larvae and lead to the high shrimp mortality. Although affected on shrimp survival, addition of V. harveyi have no significant effect to the weight of shrimp post larvae between treatments.

The existence of COVID-19 has had a very large impact on economic conditions throughout the world, one of the business fields that has been greatly affected by this pandemic is the business sector of tourism activities. Until now, people in the Province of Bali have relied heavily on businesses in the tourism sector, which directly experienced a tremendous impact due to economic shocks, so that this condition resulted in several people who depended on tourism for their livelihoods choosing to return to their home villages due to layoffs or losses due to business. which is not profitable. Buleleng Regency has an area of ??1,365.88 km² or 24.25% of the island of Bali, so it has the largest land and water area in the Province of Bali. There are many activities that can be used as a source of livelihood during this pandemic, one of which is fish farming. Catfish farming is one of the activities of choice in the midst of this pandemic because it is practical and productive. Practical because it is easy to apply and can even use plantation land as a location for cultivation and produce because the harvest can not only be consumed by cultivators but can also be sold which of course provides economic value. The purpose of this service activity is to provide solutions to problems of economic opportunity for communities affected by COVID-19 and the use of plantation land for catfish cultivation with the application of round tarpaulin ponds, so as not to interfere with the main commodities of the plantation land. Tarpaulin ponds are one solution for the development of catfish cultivation on plantation land so that the land, in addition to getting production from its main commodity, also gets additional results from catfish production. The service activity took place on August 21, 2021 in Galungan Village by involving the community starting from the preparation, implementation, and evaluation stages. The community was very enthusiastic about following the presentation from Mr. Dr. Pande Gde Sasmita Julyantoro, S.Si., M.Si and Mr. Nyoman Agus Sudarta, S.Pi, judging by the feedback given by the community in the form of questions related to catfish farming using tarpaulin ponds.

Swordfish (Trichiurus lepturus) with the local name Layur is one of the demersal fish commodities that has high economic value because it is an export commodity with high omega 3 content.. The high demand for layur fish must be supported by good fish quality and quality. The quality control is needed related to fish diseases, one of which is fish parasites. Endoparasite infection in marine fish can be zoonotic and dangerous if consumed by humans. This research was conducted to determine the intensity, prevalence, abundance and correlation of fish sex with the number of endoparasites. The research sample was obtained from the Kedonganan Fish Market, Bali which was held from September 2022 to November 2022. The sampling method was carried out by purposive sampling by paying attention to the secondary sexual characteristics of the swordfish. The total sample of fish examined was 36 fish consisting of 18 male fish and 18 female fish. Endoparasites of the genus Acanthobothrium were parasites with the highest intensity and abundance values, namely 46.05 ind./fish and 28.14 ind./fish, while the highest prevalence value was obtained from the Genus Lecithochirium of 86.11%. The correlation between fish sex and the number of endoparasites was analyzed using the Mann â€“ Whitney test with an Asymp value. Sig 0.506 and Z value -0.665. These results showed an insignificant relationship (p > 0.05) between the sex of the fish and the number of endoparasites in the whitefish that were sampled in this study. Keywords: Endoparasites; Gender; Number of Parasites; Trichiurus lepturus
