This study aims to determine the prevalence and intensity of parasitic infections in layur fish (T. lepturus) sold in Kedonganan Fish Market. Layur fish (T. lepturus) were studied as many as 40 birds and identified in the Fisheries Science Laboratory, Faculty of Marine and Fisheries, Udayana University. Parasites observed were ectoparasites and endoparasites. The results of the research data were analyzed by calculating the difference in prevalence, intensity of infection, and correlation test to determine the relationship between length and intensity, weight with intensity, and descriptive calculation to determine the level of infection in various organs. The results showed that the prevalence of parasitic infections in layur fish (T. lepturus) marketed in the Kedonganan Fish Market was included in the ‘always’ category with a value of 95%. According to William and Bunkley (1996), this ‘always’ category illustrates that ordinary parasites infect fish by 90-98%. The intensity of parasitic infections was 815 parasitic individuals with an average intensity of 21.44 parasites / fish. After a correlation test, the relationship between the length and weight of the fish with the intensity of parasitic infection was positively correlated but with a weak relationship with values ??of 0.029 and 0.146, where each fish increased in length and weight, it did not necessarily increase the intensity of parasitic infections.

The Indian scad (Decapterus russeli) is a pelagic fish that has high economic value, found throughout the Indonesian waters. The availability of Indian scad resources makes this fish easy to find, especially in Kedonganan Beach, Bali. The use of Indian scad for human consumption makes it necessary to pay attention to the quality of indian scad in order to avoid fish diseases, such as parasites. The attack of endoparasites in Indian scad can be zoonotic, which can be dangerous for humans who consume them, so research is needed to determine the density of endoparasite attacks and the percentage of endoparasites in indian scad. Samples of Indian scad (D. russeli) were obtained randomly from PPI Kedonganan and Kedonganan Fish Market. The observed organs were intestines, gonads and liver. The research was conducted for 1 month from 16 December 2020 to 17 January 2021 and fish samples were taken by random sampling. There were 35 fish samples (D. russeli) examined. The endoparasites found were Anisakis sp. (316 individuals), Camallanus sp. (15 individuals), and Lecithocirium sp. (33 individuals). The highest intensity in the genus Anisakis was 9.2 ind/fish and was classified as moderate infection and the highest prevalence was also in the Anisakis genus, which was 97.14% with (almost always categories), 60% of the genus Lecithocirium (very frequent categories), and the Camallanus genus of 28.50% with (frequent category).

The prospect of developing freshwater fish farming development in Indonesia has been promising. One of the freshwater fish commodities that has a high economic value and market demand is tilapia (Oreochromis niloticus). This research aims to determine the optimal sex ratio for tilapia broodstock to produce the best quantity and quality of tilapia larvae. The research was conducted in December 2019 to February 2020 at Unit Pelaksana Teknis (UPT) Pasar Benih Ikan dan Balai Benih Ikan Denpasar. The method use is an experimental with complete random design with 3 treatments and 3 replicates. The sex ratio for this research was a ratio between males and females of 1:2, 1:3, 1:4. Observed parameters were fish larvae quantity, absolute weight and length tilapian larvae, survival rate tilapia larvae and water quality. The results of this research showed that sex ratio of tilapia has a significant effect (P < 0,05) on the quantity of tilapia larvae, with the highest quantity was obtained from the treatment B (sex ratio of 1:3) about 1305±393 individu, but the quality of the tilapia larvae e.g. absolute weight, length and survival rate were not significantly influenced by sex ratio of tilapia broodstock (P > 0,05). Water quality parameter including temperature, dissolved oxygen (DO) and potential of hydrogen (pH) were still at a range that supports tilapia life during the research period.

Teknologi akuakultur resirkulasi adalah sebuah sistem sirkulasi air dengan menggunakan kembali air untuk budidaya, sehingga mengurangi penggunaan air dari luar sistem. Menggunakan teknologi akuakultur resirkulasi ini, biota budidaya akan lebih sehat dan kadar sirkulasi makanan lebih rendah dari perikanan secara konvensional. Tujuan penelitian ini untuk mengetahui gambaran kondisi hepatopankreas udang hasil teknologi budidaya Recirculating Aquaculture System (RAS) dengan padat tebar yang berbeda. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 3 kali ulangan, yaitu RAS padat tebar 500 ekor/m2, RAS padat tebar 750 ekor/m2, dan kontrol berupa budidaya sistem intensif flow through (konvensional) padat tebar 200 ekor/m2. Prosedur pembuatan sampel histologi hepatopankreas udang vanamei dilakukan berdasarkan prosedur Austin dan Austin (1989). Hasil penelitian menunjukkan perubahan struktur hepatopankreas pada udang uji berupa nekrosis, vakuolasi, dan indikasi mineralisasi. Pada teknologi budidaya RAS padat tebar 500 ekor/m2 kondisi hepatopankreas mengalami peningkatan kualitas pada bulan ke-2, karena nekrosis, vakuolasi, dan mineralisasi pada tubulus mengalami penurunan, sehingga lebih banyak tubulus utuh yang berada pada kondisi normal. Sedangkan pada teknologi budidaya RAS padat tebar 750 ekor/m2 dan kontrol kondisi hepatopankreas mengalami penurunan kualitas pada bulan ke-2. Tetapi pada teknologi budidaya RAS padat tebar 750 ekor/m2 lebih baik daripada kontrol, karena pada kontrol tidak ditemukan tubuli normal yang mengindikasikan hepatopankreas mengalami kerusakan. Kualitas air budidaya pada tambak udang uji masih dikategorikan normal dan memenuhi baku mutu untuk pemeliharaan udang vanamei.

Culture media is one of the important factors for microalgae growth. Adding fertilizer to culture media can influence the density of Spirulina sp. The use of rice water can be used as an alternative fertilizer for culture media because it is good for the growth of Spirulina sp. Rice water contains nutrients including nitrogen, phosphorus and vitamin B1. This study aims to determine the effect and determine the concentration of rice water media on the growth rate of Spirulina sp. culture. The experiment was conducted in December 2018 to January 2019 at Greath Hall of Brackishwater Aquaculture Fisheries (BBPBAP) Jepara, Central Java. The experiment used a completely randomized design (CRD) with five treatments and three replications. The test material in the study was Spirulina sp. with an initial density of 5×103 cells/ml and the fertilizer used is rice water and walne. The main parameters observed were Spirulina sp. cell density. while the supporting parameters observed were measurements of temperature, pH, DO, salinity, nitrate and phosphate. The dosage of adding rice washing water is treatment A1 (1 mL/L), A2 (3 mL/L), A3 (5 mL/L), K- (0 mL/L) and K + using walne fertilizer with an optimum dose of 0.5 mL/L. The results showed that the addition of rice water had a positive effect on the growth rate of Spirulina sp. The addition of rice water produces the optimum growth rate in treatment A1 which is equal to 0.57±0.001 cells/day. The ANOVA test results showed that the addition of rice water had a significant effect (P <0.05) on the growth rate of Spirulina sp.
