Abstract

Microplastics are particles that have a size of <5 mm and their existence might be able to contaminate the biota in the aquatic environment, such as care fish. Caru fish was collected in the Dumai city fish landing base in September - December 2022 to determine the abundance of microplastics in caru fish. The method used in this study is a survey method; samples of caru fish were obtained from Fish Landing Base (PPI) Dumai, and the samples were analyzed for the microplastic content in the laboratory. The samples used were 90 caru fish divided into three size classes. The parameters measured included type of microplastic, microplastic abundance, microplastic colour and the relationship between care fish size and microplastic abundance. The abundance of microplastics from the three size class of fish shows that the size class 22.1-24 cm had a higher average abundance of microplastics with an average value of 5.7 particles/individual. The type of microplastics found in this study were fibre, film and fragment. The relationship between the length of the caru fish and the abundance of microplastics has not been influenced by the size of the carp fish

Abstract

Striped catfish (Pangasianodon hypophthalmus) is a widely cultivated type of superior food fish. Intensive cultivation of catfish can cause disease. Feeding striped catfish with guava leaf extract is expected to reduce stress, which can be seen in striped catfish's hematological and physiological conditions. This research aims to obtain a dose of guava leaf extract (Psidium guajava L) to improve the health of striped catfish. The method used in the study was an experimental method that applied a one-factor, Completely Randomized Design (CRD) with five treatment levels. The treatment used was without adding guava leaf extract (P0); P1, P2, P3, and P4 with doses of 25, 50, 75, and 100 mL/kg feed, and all treatments were tested against Aeromonas hydrophila. The fish used in this research were 250 striped catfish seeds measuring 6-8 cm and kept for 45 days. Feeding with the addition of guava leaf extract at a dose of 75 mL/kg of feed had an influence on the hematological and physiological profile of post-challenge catfish, such as total erythrocytes of 2.40x106 cells/mm3, hematocrit 35.66%, hemoglobin levels 9.61 g/dL, total leukocytes 10.54x 104 cells/mm3, blood glucose levels of 78.00 mg/dL and phagocytic activity 35.66%.

Abstract

The potential for developing marine tourism in Sikabau Beach focuses on integration with the local salted fish processing industry and the importance of synergy between the two sectors, considering that Jorong Sikabau has stunning natural beauty and maritime traditions, including salted fish processing that has been passed down from generation to generation. However, the salted fish processing industry still faces challenges, such as limited market access, lack of technical knowledge, and inadequate infrastructure. This study aims to describe the tourism picture and characteristics of salted fish processors and analyze the empowerment of salted fish processors. The method used in this study is a case study method using a qualitative approach. The selection of informants in this study was purposive. The data analysis used was qualitative, starting from data reduction, data display, and drawing conclusions. The study results showed that the characteristics of Sikabau Beach marine tourism are mangrove forest tourism, Batu Kajang, and the estuary of Sikabau Beach. The attributes of salted fish processing businesses are that they still carry out the processing process traditionally. The empowerment carried out for salted fish processors is training in processing fish-based products and their marketing, fish packaging, and how to reproduce good processed food. The programs that have not been implemented are business strengthening and strengthening the added value of products. Therefore, there needs to be support from the government that focuses more on skills training for salted fish processors and the development of adequate infrastructure for salted fish processors.

Abstract

Majalaya carp (Cyprinus carpio) is one of the essential commodities used to increase fisheries production in Indonesia. However, this cultivation activity is often hampered by disease problems caused by parasites. Therefore, it is necessary to research the inventory of ectoparasites in Majalaya carp with different sizes. This study aims to determine the type, intensity, and prevalence of ectoparasites in Majalaya carp of different sizes. Samples were taken by random sampling from cultivation ponds in the North Minahasa Regency, North Sulawesi Province. The research method used a descriptive method, and for ectoparasite examination, a native method was used by examining the surface of the fish's body, mucus, fins, gills, and eyes. The study results found six types of ectoparasites: Dactylogyrus sp, Argulus sp, Ichthyophthirius multifiliis, Trichodina sp, Vorticella sp, and Gyrodactylus sp. At a size of 4-7 cm, more Dactylogyrus sp were found. On the gills, size 8-14 cm I. multifiliis on mucus and size 23-30 cm Argulus sp on the surface of the fish body. The intensity level of ectoparasites produced on Dactylogyrus sp reached a value of 5.14 Ind/fish (low infection), I.multifiliis 4.27 Ind/fish (low infection), and Argulus sp of 3.80 Ind/fish (low infection). Then, the prevalence level of ectoparasites produced on Dactylogyrus sp reached a value of 70% (moderate infection), Ichthyophthirius multifiliis 50% (persistent infection), and Argulus sp 67% (persistent infection). This study emphasizes the importance of water quality management and fish density regulation.

Abstract

Essential fatty acids play a crucial role in fish growth and health. A quality feed containing the right amount of fats can promote fish growth and support metabolic functions. Fatty acid requirements vary depending on the fish species and habitat, with freshwater fish tending to require more n-6 fatty acids, while marine fish require more n-3 fatty acids. The use of fat in feed should be well regulated, as too high levels can interfere with the digestive and metabolic processes of the fish. The use of fish oil mixed in feed as much as 1.5% can help improve the growth performance of carp. Magot oil mixed into the feed as much as 15%/100 g gives the best growth performance in carp. Soybean oil used as much as 10% in feed can increase the content of omega 3, EPA, and DHA in catfish meat. Coconut oil used in feed at 6% proved to have a good impact on the DHA content of tilapia. The purpose of this paper is to review the literature on the role and function of fatty acids in fish growth.
