Abstract

To overcome excess residues and fish mortality rates during transportation, natural ingredients, namely clove oil, can be used. Compounds in clove oil are considered safe because they use natural ingredients. The purpose of this study was to determine the effectiveness of using clove oil as an anesthetic agent with different doses on the length of time of unconsciousness and survival rate of tilapia. This research was conducted from May to June 2023. This research was carried out at the Bungus Fish Seed Center, Padang, and West Sumatera. The method used in this study is the experimental method. The design used in this study was a completely randomized design (CRD) consisting of 4 treatments and 3 replications. The treatment used in this study is use of clove oil with different doses. Treatment A1 = 0.5 ml L-1 water, A2 = 1 ml L-1 water, A3 = 1.5 ml L-1 water and A4 = 2 ml L-1 water. Observations of changes in tilapia behavior and water quality were analyzed descriptively, while the length of time of stupor and survival of tilapia obtained during the study were analyzed using analysis of variance (ANOVA). To see the differences between treatments, the Duncant Multiple Range Test (DMNRT) was performed. Data is processed using the SPSS 26 program. The conclusion that can be considered in this study is that the administration of clove oil with different doses as an anesthetic has a significant effect on the longest induction time, on the length of time the fish were unconscious, the length of time the fish regained consciousness and survival rate of tilapia. In treatment A2 with a dose of 1 mL L-1 of water, it was optimal to stun tilapia for 244 minutes with a survival of 88.89%.Keywords:Clove oilFish transportationTilapia

Abstract

Ectoparasites pose a significant threat to the health and productivity of vaname shrimp (Litopenaeus vannamei) in aquaculture settings, particularly in tropical regions. This study aimed to assess the prevalence, intensity, and dominance of ectoparasites in vaname shrimp ponds in Padang Pariaman, West Sumatra. This study was conducted from March to May 2024 in vaname shrimp ponds in Padang Pariaman, West Sumatra. Sampling was carried out at five different pond stations, and water quality assessments were carried out. Ectoparasites were identified, and their prevalence, intensity, and dominance were measured. Station II had the highest prevalence (100%), intensity (69 ind/shrimp), and dominance of ectoparasites from all other observation stations. The dominant types of ectoparasites were Epystylis sp. (37.81%), Zootamnium sp. (18.65%), and Vorticella sp. (20.64%). Water quality at five Vaname shrimp pond stations showed significant variations, especially in pH, COD, and ammonia parameters, with some values exceeding the quality standard. Station V was identified as the most critical location with the highest COD (90.08 mg/l) and ammonia (0.188 mg/l) values and pH below the optimal threshold. It is important to implement better pond management strategies to improve shrimp health and productivity while minimizing the ectoparasites on aquaculture systems in tropical regions.Keywords:Vaname shrimpEctoparasitesAquaculture managementWater quality

Abstract

This research is scheduled to take place from May to August 2022 at the Marine and Brackish Water Aquaculture Fisheries Center in West Sumatra. The method employed will be observation, which entails monitoring the eating behavior of lobsters and their feeding schedule every time food is provided within a 24-hour timeframe. Data pertaining to lobster eating behavior will be analyzed descriptively based on these observations. Throughout the research, various feeding activities of sand lobsters were documented. The observational results indicated that the lobster feeding process remained consistent. The lobster typically initiates the process by gripping the food with its claws and feet, subsequently breaking it into smaller pieces with its claws, and then placing these fragments into its mouth. As the lobster tears apart the food, the next step involves transferring it to the mouth using the nearest upper and lower jaws. In light of this research, it can be inferred that lobster feeding behavior encompasses the following steps: firstly, the lobster approaches the food after spotting it; secondly, lobsters employ their claws to grasp the food; and finally, lobsters tear and ingest the food. Lobster feeding activities are most commonly observed between 6:00 PM - 10:00 PM and 10:00 PM - 2:00 AM.Keywords: eating behavior; lobster; Lobster feeding schedule.

Abstract

Penelitian ini bertujuan menganalisis karakteristik morfometrik dan hubungan panjang–berat kerang lokan (Polymesoda sp ) di Sungai Batang Masang, Kabupaten Agam, Sumatera Barat. Sampel dikumpulkan dari tiga lokasi, yaitu kawasan permukiman, sekitar jembatan, dan daerah muara. Parameter yang diamati meliputi panjang, lebar, dan tinggi cangkang, serta bobot tubuh. Hasil penelitian menunjukkan bahwa kerang dari stasiun muara (Stasiun III) memiliki ukuran rata-rata paling besar dengan panjang 54,39 ± 1,88 mm dan bobot 29,63 ± 1,59 g. Analisis regresi panjang–berat menunjukkan pola pertumbuhan alometrik negatif (b 3) di seluruh stasiun, yang berarti pertumbuhan panjang lebih cepat daripada penambahan bobot. Faktor lingkungan, terutama kandungan oksigen terlarut dan jenis substrat, berperan penting dalam memengaruhi pertumbuhan kerang. Kajian ini menegaskan bahwa analisis morfometrik dapat dimanfaatkan sebagai indikator biologis kondisi ekosistem estuaria sekaligus sebagai dasar dalam pengelolaan berkelanjutan sumber daya kerang lokan.

Abstract

Kemajuan teknologi genomik telah merevolusi pendekatan penelitian dan pemuliaan ikan nila (Oreochromis niloticus), yang sebelumnya berbasis fenotip menjadi lebih terarah pada informasi genetik. Penelitian ini bertujuan menelaah perkembangan, penerapan, serta efektivitas berbagai inovasi genomik dalam pemuliaan ikan nila melalui metode Systematic Literature Review (SLR) terhadap sepuluh artikel ilmiah terbitan tahun 2015–2025. Kajian ini mengidentifikasi sejumlah teknologi utama yang digunakan, termasuk Genomic Selection (GS), Genome-Wide Association Studies (GWAS), RNA Sequencing (RNA-Seq), Marker-Assisted Selection (MAS), serta teknik penyuntingan gen berbasis CRISPR/Cas9. Hasil tinjauan menunjukkan bahwa penerapan seleksi genomik mampu meningkatkan akurasi nilai pemuliaan sebesar 30–34% dibandingkan metode konvensional. Pendekatan GWAS berhasil menemukan lokus penting pada kromosom 5 dan 7 yang terkait dengan laju pertumbuhan serta efisiensi pakan. Analisis RNA-Seq mengungkap lebih dari 500 gen berbeda ekspresi yang berperan dalam mekanisme adaptasi terhadap stres salinitas, sedangkan penerapan CRISPR/Cas9 terbukti efektif menghasilkan populasi jantan tanpa penggunaan hormon sintetis. Sementara itu, program pemuliaan konvensional di Kenya dan Uganda masih menunjukkan peningkatan pertumbuhan sekitar 20% per generasi, meskipun belum sepenuhnya mengintegrasikan teknologi genomik. Secara keseluruhan, penerapan teknologi genomik berpotensi besar untuk mempercepat peningkatan produktivitas ikan nila, menjaga keberlanjutan sistem budidaya, serta memperkuat pengelolaan sumber daya perairan secara efisien dan ramah lingkungan

Abstract

Ectoparasites pose a significant threat to the health and productivity of vaname shrimp (Litopenaeus vannamei) in aquaculture settings, particularly in tropical regions. This study aimed to assess the prevalence, intensity, and dominance of ectoparasites in vaname shrimp ponds in Padang Pariaman, West Sumatra, and to identify factors influencing their distribution. Sampling was conducted across five different pond stations, with each station subjected to regular water quality assessments, temperature monitoring, and parasitological examinations. Ectoparasites were identified and quantified using standard microscopic techniques to determine prevalence, intensity, and dominance. Results indicated that Station II had the highest prevalence (100%) and intensity (69) of ectoparasites, likely due to poor water quality, fluctuating temperatures, and inadequate pond management practices. In contrast, Stations I, III, IV, and V exhibited lower levels of ectoparasite infestation, with Station I having moderate prevalence (80%) and intensity (21) and the remaining stations showing relatively low infestation levels. The dominant ectoparasites identified were Epystylis sp, Zoothamnium sp, Vorticella sp, and Ichthyobodo sp, with varying levels of dominance across the stations, suggesting a correlation with environmental conditions and pond management practices. Effective management of water quality, stocking densities, and regular monitoring can help mitigate ectoparasite infestations in shrimp ponds. This research provides essential insights into sustainable shrimp aquaculture practices, emphasizing the importance of improved pond management strategies to enhance shrimp health and productivity while minimizing the impact of ectoparasites on aquaculture systems in tropical regions.
