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. Keywords: Endoparasites; Gender; Number of Parasites; Trichiurus lepturus

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

Penelitian ini dilakukan untuk mengetahui pola pertumbuhan rumput laut (Eucheuma cottonii) yang menggunakan kantong dan tanpa kantong di perairan pantai Geger pada bulan Oktober-November 2022. Pengambilan data dilakukan seminggu sekali selama 6 minggu penelitian. Metode budidaya yang digunakan dalam penelitian ini adalah metode lepas dasar dengan perlakuan menggunakan kantong dan tanpa kantong (konvensional). Penelitian ini di rancang dengan menggunakan Rancangan Acak Lengkap (RAL). Untuk mengetahui data SGR (laju pertumbuhan berat per hari) dapat dianalisis menggunakan uji One Way Anova, dengan tingkat signifikan 5% dari hasil analisisnya yaitu 95%. Uji statistik dibantu dengan menggunakan software SPSS PC. var 25.0. Hasil penelitian ini menunjukkan bahwa pertumbuhan rumput laut pada penggunaan kantong lebih tinggi dari tanpa kantong. Berat rumput laut pada penggunaan kantong di minggu ke-6 sebesar 666 g dan tanpa kantong di minggu ke-6 hanya sebesar 375 g. Specific Growth Rate (SGR) pada penggunaan kantong sebesar 5,53%/hari sedangkan perlakuan tanpa kantong sebesar 2,12%/hari. Hal ini terjadi karena banyak rumput laut yang patah akibat arus dan dimakan oleh predator pada perlakuan tanpa kantong. Parameter kualitas air yang diukur selama penelitian mendapatkan kisaran hasil yang sesuai untuk pertumbuhan rumput laut yaitu, suhu 26,7-30ºC, salinitas 31-35 ppt, pH 7,1-8,0, DO 5,9-6,7 mg/L, nitrat 0,034-0,057 mg/L, fosfat 0,011-0,066 mg/L, kecepatan arus 0,31-0,50 m/s dan kecerahan 60-107 cm. Nilai pengukuran nitrat dan fosfat di perairan Pantai Geger tergolong rendah namun masih dapat mendukung dalam kegiatan budidaya rumput laut. Pertumbuhan rumput laut pada penggunaan kantong lebih baik dari pada tanpa kantong dengan selisih berat sebesar 291 g pada akhir penelitian. Hasil ini masuk kategori baik dalam budidaya rumput laut.

Abstract

Benoa Port is one of the public ports as well as a special export fishing port. The existence of transportation activities at Benoa Port is indicated to have an indirect pollution impact on the waters, so that research related to the heavy metal content of lead (Pb) and cadmium (Cd) in water and water quality conditions in the waters of Benoa Port Denpasar is important to do. Water sampling was carried out at Benoa Port, then the samples were analyzed at the Analytical Laboratory of Udayana University from June-July 2023.The tested water samples were taken from 3 points with 3 repetitions at each point. Point 1 is at the port entrance, point 2 is at the port of the fishing town and point 3 is at RTH Taman Segara. Data from the study was obtained that the highest Pb value was at point 2, which was 0.1 mg/l and the Cd value was 0.054 mg/l. At point 3 the Pb value is 0.025 mg/l and the Cd value is 0.018 mg/l, and the lowest is found at point 1 with a Pb value of 0.02 mg/l and a Cd value of 0.016 mg/l. Water quality parameters measured include temperature, pH, Dissolved Oxygen (DO), and Total Dissolve Solids (TDS). The highest temperature value is found at point 2 of 29.8oC while the lowest temperature value is found at point 1 with a value of 28.6oC.

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.
