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.

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

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.

The utilization of rice washing water waste from households has not been optimized, even though it contains a large amount of essential nutrients for plant growth. This waste can be utilized as natural fertilizer for horticultural plants. Rice washing water provides various benefits for plants, is easily accessible to farmers, and is also environmentally friendly. Additionally, its price is very affordable so it can be accessed by farmers. The purpose of this activity is to increase knowledge and understanding of the community in making Liquid Organic Fertilizer (LOF) derived from rice washing water waste, as well as to reduce the use of chemical fertilizers by shifting to organic fertilizers to maintain soil and environmental quality. This activity was conducted in Nagari Lawang, Matur District, Agam, West Sumatra. The method used was through lectures and demonstrations of liquid organic fertilizer (LOF) production. The results of this activity showed that the interaction between the organizers and participants had a positive impact, improving skills, and motivating PKK mothers in plant cultivation. The home garden is seen as a productive land for nutrition and income, but there are obstacles such as lack of knowledge and capital. Overcoming these obstacles requires increasing technical knowledge and providing capital. Furthermore, this activity also resulted in increased knowledge and active participation in the process of making liquid organic fertilizer. The conclusion of this activity is to increase knowledge and skills in making LOF, motivating intensive plant cultivation. Public interest in making LOF from waste is high, increasing knowledge and skills in producing organic fertilizer for successful plant cultivation.

Fish farming is one of the most popular activities in the community. However, a common obstacle for fish farmers is the attack of diseases that attack cultured fish. Bacterial infection is one example of a disorder that often attacks farmed fish and causes losses in fish farming. Due to side effects and drug resistance, the use of chemical drugs and antibiotics in fish has been restricted. On the other hand, efforts can be made to improve the prevention and treatment of fish diseases by the use of herbal plants. This article discusses studies on the use of herbal materials that enhance fish immunity and resistance to bacterial diseases and focuses on the types of herbal plants. The review results show that the use of herbal plants for the management and control of diseases affecting fish populations effectively shows a higher level of efficiency and poses a much lower risk to the health of aquatic organisms and can be a more economical alternative when compared to frequently used chemical drugs.

Abstract. Lubis AS, Efrizal, Syaifullah, Rusnam, Nurmiati, Puari AT. 2023. Growth performance and survival rate of spiny lobster Panulirus homarus (Linnaeus, 1758) with formulated feeding enriched by spinach extract. Biodiversitas 24: 6010-6016. In the context of spiny lobster Panulirus homarus (Linnaeus, 1758) aquaculture and marine conservation, assessing factors that influence growth and survival is critical. Spinach extract can be added as a feed additive to enhance the growth and survival rate of lobsters. This study aimed to analyze the effect of formulated feed enriched with spinach extract on spiny lobsters' growth and survival performance. A completely randomized design with five treatments and five replications: formulated feed with spinach extract 0 mg (Feed A1), 0.4 mg (Feed A2), 0.5 mg (Feed A3), 0.6 mg (Feed A4), and 0.7 mg (Feed A5) were used. The result showed that the formulated feed enriched with spinach extract had a significant effect on absolute weight, specific growth rate, length, and width of the carapace in growth performance (P<0.05) but had no significant on the survival rate and the molting frequency (P>0.05). The best result was treatment A3, adding 0.5 g of spinach extract to lobster feed with absolute weight 39.67±6.20 g, length of carapace 0.46±0.06 cm, width of carapace 0.28±0.05 cm, specific growth rate 0.38±0.06% day-1, molting frequency 1.00±0.00 times lobster-1, and survival rate 100±0.00%. The Spinach extract of 0.5 mg was the best for the survival and growth of the lobster (Duncan's test). The chemical of the feed showed that the tested feed met the nutritional needs of lobsters with a protein content of 39.74-42.60%. However, the number of amino acids in the best test feeds was still low quantity compared to several other studies, so the growth of lobsters was still slow. Based on research results, enriched 0.5 g of spinach extract to formulated feed is the best result for increasing the growth and survival rate of lobsters.

Abstract. Suparno, Yusra, Lubis AS, Viza AFY. 2024. Influencing the environmental factors on the abundance of puerulus Panulirus homarus in the Mentawai Islands, West Sumatra, Indonesia. Biodiversitas 25: 3758-3767. The lobster puerulus, the final larval stage of the spiny lobster, is significantly influenced by environmental factors, making it crucial for sustainable aquaculture development. This study aimed to analyze how these factors affect the abundance of puerulus Panulirus homarus (Linnaeus, 1758) in the Mentawai Islands, West Sumatra, Indonesia has practical implications for aquaculture. A one-way analysis of variance revealed that the temporal period significantly impacts the abundance of puerulus P. homarus (P<0.05). In February (west season), the abundance was not significantly different from April (transition season I), but both differed significantly from June (east season). The highest abundance occurred in June (33.8±4.21 ind/trip), followed by April (27.00±5.00 ind/trip) and February (23.20±2.22 ind/trip). Regression analysis showed that temperature (R²=0.8111), salinity (R²=0.5158), and phosphate (R²=0.5492) strongly correlated with puerulus abundance. In contrast, chlorophyll-a (R²=0.2236), nitrate (R²=0.4136), and sea current velocity (R²=0.0223) were less significant. These results emphasize the importance of temperature, salinity, and phosphate as key factors influencing puerulus distribution, providing valuable insights for sustainable aquaculture. Environmental parameters were observed using Aqua Modis satellite imagery. They included Sea Surface Temperature (SST), chlorophyll-a concentration, and current velocity, showing a good correlation with field measurements from the Copernicus Marine Environment Monitoring Service (CMEMs).

Abstract. Kamal E, Lubis AS, Mayzuri Z, Hertati R. 2025. Biodiversity of the ichthyofauna in the estuary area of Padang, West Sumatra, Indonesia. Biodiversitas 26: 2621-2630. Estuaries are transitional ecosystems between marine and terrestrial environments, characterized by high biodiversity and a crucial role in maintaining aquatic ecosystems. This study aimed to identify the diversity, distribution patterns, and environmental influences on ichthyofauna in the estuaries of Padang, West Sumatra, Indonesia. Fish sampling was conducted in five estuarine sites from July to December 2024 using habitat-specific fishing gear, while water quality parameters, including temperature, salinity, pH, and dissolved oxygen, were measured in situ. Data analysis included species identification, Shannon-Wiener Diversity Index, Evenness Index, Simpson Dominance Index, and correlation and regression tests to evaluate the relationship between environmental factors and ichthyofauna biodiversity. Results indicate varying fish distribution across sites, with Teluk Buo exhibiting the highest diversity (H': 3.27), while the Batang Arau River Estuary showed species dominance and low diversity. The highest Evenness Index was recorded in the Batang Arau and Anai River Estuaries, where the highest Simpson Dominance Index was found in the Anai River and Batang Arau estuaries, primarily dominated by Rasbora sp. (28 individuals) and Ambassis tetra (21 individuals). Fish distribution was influenced by environmental factors such as food availability, habitat complexity, water quality, and interspecies interactions. More structurally complex habitats supported higher biodiversity, while disturbances like pollution, overfishing, and habitat degradation led to species dominance and reduced biodiversity.
