Abstract

This study aims to determine the various types of parasites that infect tuna, their abundance, prevalence, level of parasite intensity and the effect of fish length on the number of parasitic infections. Fish samples were obtained from Kedonganan Beach, Bali from November-December 2021. This study used a descriptive method and data collection using simple random sampling. The total samples examined were 35 fish. The endoparasites found in the internal organs of fish which include the intestines, liver, and gonads consist of 3 different genera, namely: Rhadinorhynchus sp., Anisakis sp., and Lecithocladium sp. The highest abundance was found in the genus Rhadinorhynchus sp., the highest prevalence was found in the genus Rhadinorhynchus sp., and the highest intensity level was found in the genus Lecithocladium sp. The relationship between length and number of parasites was classified as "very weak" because the correlation between the two relationships ranged from 0.00-0.199. So, it can be concluded from the research that has been done related to the relationship between fish posture and the number of endoparasites that infect the tuna (Auxis rochei) which was landed on the beach of Kedonganan, Bali. There is no relationship between fish body posture and the number of endoparasite infections or can be classified into the category of a "very weak" relationship.

Abstract

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 – 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.

Abstract

Tilapia is a type of fish favored by freshwater fish consumers because it is easy to cultivate. The problem faced in freshwater fish farming activities is the high price of artificial feed. To deal with these problems, alternative feeds are needed to reduce the use of artificial feeds such as sudden apu wood (Azolla pinnata). This study aims to determine the effectiveness of the sudden apu wood (Azolla pinnata) on the growth and survival of tilapia (Oreochromis niloticus) and to help fish farmers reduce the use of artificial feed. The research method used is an experimental approach method. The experimental design in this study was a Randomized Block Design (RAK) which consisted of 3 treatments with 3 replications. Treatment A (direct feeding of 100% Azolla pinnata plants), Treatment B (direct feeding of 50% Azolla pinnata plants and 50% pellets), and Treatment C (100% pellet feeding). The results showed the absolute weight growth of treatment A 12.18±5.66 g, treatment B 17.73±4.40 g, treatment C 24.53±3.80 g. The absolute length growth of treatment A was 2.22 ± 0.60 cm, treatment B 2.54 ± 0.40 cm, treatment C 3.50 ± 0.37 cm. The survival rate of treatment A was 66.67±11.54%, treatment B and treatment C were 100±0%. Feed conversion ratio (FCR) for treatment A 4.8±2.28, treatment B 2.1±0.45, treatment C 1.7±0.17. The water quality of the three feeding treatments had no significant effect on pond water quality and was still within the optimal range for tilapia growth and cultivation.

Abstract

Lingkungan yang ekstrim telah banyak dilaporkan dapat memicu terjadinya stres pada mahluk hidup yang terpapar, sehingga mengganggu kondisi homeostasinya. Dalam keadaan tertekan, organisme vertebrata akan melepas hormon-hormon stres, seperti katekolamin Norepinephrin (NE) dan Dopamin (Dopa), yang melibatkan axis hypothalamus-sympathetic-chromaffin (HSC) dan axis hypothalamus–pituitary-interrenal (HPI). Kedua sistem axis tersebut berturut-turut menghasilkan hormone katekolamin (antara lain adrenalin, noradrenalin, dan dopamine) dan hormon kortikosteroid (terutama kortisol). Kehadiran kedua kelompok hormon tersebut pada sistem peredaran darah inang berperan sebagai signal bagi bakteri patogen, seperti Aeromonas hydrophila, yang umum ditemukan dalam akuakultur, untuk memulai proses infeksinya. Hormon berperan untuk mengaktifkan gen-gen dalam aktivitas dan pembentukan flagella (memungkinkan sel bakteri berenang dengan cepat menuju inangnya), pembentukan pilli, produksi toksin, dan mengaktivasi proses pembentukan biofilm. Dengan kata lain, kondisi stres pada inang ini mempengaruhi metabolisme, pertumbuhan dan virulensi bakteri patogen tersebut, karena kondisi sistem imun inang berada pada titik terendah ketika organisme tersebut mengalami stres. Sekresi hormone katekolamin juga merupakan signal bagi bakteri patogen untuk mengaktifkan gen ferric uptake regulator (fur gene) yang berperan dalam proses pengkhelatan zat besi (Fe3+) di lingkunganya, sehingga terjadi pertumbuhan berlebih dari patogen tersebut. Peran hormone katekolamin dalam peningkatan patogenitas patogen adalah melemahkan ikatan kompleks protein transferrin dengan zat besi (Fe3+), sehingga terjadi peningkatan laju pertumbuhan patogen yang akhirnya berdampak pada peningkatan patogenitasnya. Kata kunci : Akuakultur, Endokrinologi mikroba, Patogenisitas, Stres.

Abstract

Seaweed cultivation is one of the leading commodities in the fishing sector and is still occupied by most coastal communities. One of the types of seaweed that can be cultivated is Eucheuma cottonii. One of the areas in Badung Regency that was once a place for seaweed cultivation is the South Kuta District, Badung Regency, Pandawa Beach, to be exact. The problem most often faced by seaweed cultivators is that seaweed cannot grow properly. The cause of seaweed not being able to grow properly occurs due to predators eating the seaweed thallus. Therefore, a study was conducted to determine the appropriate location on the Pandawa Beach for the cultivation of seaweed Eucheuma cottonii. The research method was carried out by planting Eucheuma cottonii seaweed in 3 different locations seen from the distance from the tourism position (water sport) in the waters of Pandawa Beach, first location in the water sport area, second location is 100 m to the west of the one location, third location is 100 m to the west of two location. The results of this study indicate that the average weight of seaweed at location 1 in the first to sixth week range 119,6 g – 399,7 g, location 2 range 121,80 g – 413,5 g, and at location 3 it ranged 123,35 g – 430,75 g. The Growth Rate (SGR) at Location 1 is 3,3%, Location 2 is 3,37%, and Location 3 is 3,47.%.

Abstract

Vaname shrimp (Litopenaeus vannamei) has advantages, such as being more responsive to feed, resistant to diseases and poor environmental conditions, fast growth, high survival rate, and high stocking density. This study aims to examine the effects of different stocking densities on the growth, survival rate, and feed efficiency of vaname shrimp. Vaname shrimp (±0.6 g/shrimp). were stocked in fiber tanks with a volume of 500 liters and filled with seawater with a salinity of 35 ppt. This study used an experimental method with 3 different stocking density treatments: 200 individual/m3 (A), 400 individual/m3 (B), and 600 individual/m3 (C), repeated three times per treatment. The shrimps were cultivated for 60 days and fed at a rate of 5% of their body weight/day four times a day. The results showed that average growth shrimp in treatment A, B, and C were 12.10 g, 10.14 g, and 7.37 g, respectively. The survival rate of shrimp in the treatmen A. B, and C were: 72%, 46,3%, and 56%, respectively. The FCR in the treatment A, B, and C were 0.95; 1.4; and 1.26. One Way ANOVA statistical analysis indicated significant differences (P<0,05) between treatments A dan C in terms of mean body weight growth, as well as between treatments A and B in terms of FCR. This study indicated that different stocking densities affect the growth, survival rates, feed efficiency, and water quality of vaname shrimp.

Abstract

The bacteria Vibrio parahaemolyticus and V. campbellii are the pathogens of Vibriosis in various marine cultured organisms. Moreover, Aeromonas hydrophila is the pathogen of the Motile Aeromonad Septicemia (MAS) disease. Therefore, it is needed to inhibit these bacteria's activity. Studies showed that the extract of seaweed Kappaphycus alvarezii could hinder the growth of gram-negative and gram-positive bacteria; however, the antibacterial activities against V. parahaemolyticus, V. campbellii, and Aeromonas hydrophila remain unknown. Thus, this study aimed to analyze the antibacterial activity, and the minimum inhibitory concentration of K. alvarezii extract against V. parahaemolyticus, V. campbellii, and A. hydrophila. K. alvarezii was collected from the cultured in the Geger Beach area, Badung Regency. The methanol K. alvarezii extracts with different concentrations (10, 5, 1, 0.05%) were dropped to the paper disk and placed on the bacterial tested cultures. Inhibition zone measurements were carried out every 6 hours during the 24-hour incubation period. Chloramphenicol and methanol were also tested as the positive and negative control, respectively. Results showed that the antibacterial activity was only demonstrated in 10% extract against V. campbellii with an inhibition zone of 12.5 mm.

Abstract

Tambak udang vaname (Litopenaeus vannamei) banyak ditemukan di Indonesia dan membutuhkan pengelolaan kualitas air yang baik untuk mendukung pertumbuhan dan kesehatan udang. Meskipun udang vaname relatif tahan terhadap beberapa penyakit, ia tetap rentan terhadap infeksi bakteri Vibrio dan virus Infectious Myonecrosis Virus (IMNV), yang dapat menurunkan kualitas produksi udang akibat kerusakan otot dan infeksi sekunder. Kelimpahan Vibrio mengacu pada jumlah bakteri dari genus Vibrio dalam air, yang dapat memperburuk kesehatan udang, terutama jika dipengaruhi oleh faktor lingkungan seperti suhu, pH, dan kualitas air yang buruk. Sementara itu, total bakteri mengacu pada jumlah keseluruhan bakteri dalam sampel air, baik yang menguntungkan maupun patogen, yang penting untuk menilai kualitas ekosistem tambak dan potensi risiko kesehatan bagi udang. Penelitian ini bertujuan untuk mengetahui kelimpahan bakteri Vibrio dan total bakteri pada air tambak udang vaname yang terindikasi terjangkit IMNV. Penelitian ini menggunakan metode deskriptif kuantitatif dengan teknik kultur mikrobiologi untuk menghitung kelimpahan Vibrio dan total bakteri. Sampel air diambil dari tambak yang terindikasi terjangkit IMNV di Bali, dengan analisis parameter kualitas air seperti salinitas, suhu, pH, DO, nitrit, dan amonia. Hasil penelitian menunjukkan kelimpahan Vibrio rata-rata 2 x 10⁴ cfu/mL dan total bakteri 3.17 x 10⁶ cfu/mL. Kualitas air tambak tersebut menunjukkan kondisi yang mendukung pertumbuhan bakteri, dengan nilai TSS dan amonia yang tinggi meningkatkan risiko bakteri patogen.
