Pollution of the freshwater ecosystem can cause adverse effects on aquatic organisms, especially fish. Fish skin is a multi-purpose tissue that serves as the first barrier to protect the fish from aquatic pollution and defense system against pathogens. Pangasiidae is an economically important riverine catfishes that generally exist in freshwater fr...

... study was conducted October -December 2018 at Aquaculture facilities of the Research Center of Limnology. Three Pangasius strains, Patin Siam (Pangasianodon hypophthalmus), Patin Jambal (Pangasius djambal), and Patin Pasupati (Pangasius sp.) were used in this study because those Pangasius strains were commonly found in Indonesia, especially Java ( Figure 1). All the fish used in this study were obtained from aquaculture farms in Bogor and Karawang. ...

... Đặc điểm chung của bệnh lở loét cá da trơn là tổn thương ăn sâu gây hoại tử trên da và cơ của cá bệnh. Da cá là loại mô linh hoạt, đóng vai trò là tuyến phòng thủ đầu tiên chống lại bệnh tật và là rào cản chống lại các chất ô nhiễm trong nước (Sadi & Yoga, 2021). Các vết loét là nơi để các sinh vật gây bệnh xâm chiếm vùng da bị tổn thương (Noga, 2000). ...
... Sự khác biệt về dấu hiệu bệnh lý này là do có sự khác biệt về thành phần collagen có trong cấu trúc da giữa nhóm cá vẩy và cá da trơn. Collagen có trong da cá là collagen loại I giàu glycine và proline đóng vai trò quan trọng ngăn ngừa nhiễm trùng và tổn thương (Sadi & Yoga, 2021). Theo nghiên cứu của Feng et al. (2023) sự loét da do vi khuẩn V. mimicus có thể tiết ra enzyme collagenase phân huỷ collagen, quá trình này sẽ chuyển hoá collagen loại I trên da cá thành hỗn hợp collagen loại I và III và khi MMP-9 và MMP-13 đến để thực hiện chức năng tái tạo mô vô tình làm cho vi khuẩn đi sâu vào trong cơ làm quá trình lây nhiễm trầm trọng hơn. ...
Bệnh truyền nhiễm do vi khuẩn xuất hiện trên cá tra ngày càng phổ biến, gây thiệt hại lớn cho người nuôi ở đồng bằng sông Cửu Long. Nghiên cứu thực hiện nhằm xác định vi khuẩn gây bệnh lở loét trên cá tra (Pangasianodon hypophthalmus) tại ao nuôi ở An Giang, Cần Thơ và Đồng Tháp. Ba chủng vi khuẩn đại diện cho từng khu vực được phân lập từ cá tra bệnh có biểu hiện lở loét, đuôi mòn và nội tạng trương phồng. Thí nghiệm cảm nhiễm cho thấy ba chủng CT5, NV9 và VH120 có độc lực cao với giá trị LD50 lần lượt là 1,66×104 CFU/mL, 3,98×104 CFU/mL và 1,58×103 CFU/mL. Cá cảm nhiễm có các dấu hiệu bệnh lở loét tương tự cá bệnh ngoài tự nhiên. Tất cả các chủng vi khuẩn phân lập là Gram âm, oxidase, catalase, O/F dương tính và sử dụng glucose, galactose hoặc D-mannitol làm nguồn carbon. Giải trình tự 16S rRNA cho thấy ba chủng vi khuẩn phân lập có độ tương đồng 99,87% với vi khuẩn Vibrio mimicus. Đây là nghiên cứu đầu tiên xác định vi khuẩn V. mimicus là tác nhân gây bệnh lở loét trên cá tra nuôi thâm canh.
... The phenotypic characteristics are streamlined body, scissors-shape of the caudal fin, silver belly, wide and sub-terminal mouth, long twin beard, soft meat texture, and delicious taste (Slembrouck et al., 2003). These last two features make Pangasius more preferred by the public, and then it is reared as an aquaculture commodity economically (Sadi & Yoga, 2021). Besides that, it grows fast when culture it and it has higher market demand (Hoque et al., 2021). ...
Pangasius sp is an introductory species that is widely distributed in freshwater regions in Indonesia since the 1990s and it was initiatively reared at the beginning of 2011 using a floating net cage in Lake Ngade, Ternate. Even though it has benefited economically, there is still a lack of information on its biological and ecological aspects. Growth and survival rate are two main factors that should be known to develop Pangasius aquaculture. The study aims to understand the growth and survival rate of Pangasius by mixing different fish meals into dietary. 120 Pangasius fingerlings were placed into 12 tanks. Diet was formulated using Pearson's square method. Three different protein fish meal sources were mixed into feed formulation namely flying fish meal, Nile meal, and eel meal. Commercial feed was used as control. Filling Randomized Design (FRD) was applied with the experimental setup of the treatments. The results show that feed stability in water ranges from 2'23" to 3'47" while feed durability ranges from 2'09" to 2'35". The survival rate of Pangasius is almost 100% except for treatment C. Growth rates vary among treatments which is the highest found in treatment A (16.42%) followed by treatment B (15.85%), D (15.57%), and C (7.00%) respectively. Nile fish meal is also significantly affected (P<0.05) by the Specific Growth Rate (SGR) of fish. Nutrition ingredients and water quality parameters are conducive to maintaining the fish's life. All in all, different fish meal sources in the formulated diet are significantly supporting Pangasius growth. ABSTRAK Ikan Patin (Pangasius sp) merupakan spesies introduksi yang tersebar di perairan tawar Indonesia sejak tahun 1990an, dan awal mula dibudidayakan di Ternate adalah di keramba jaring apung Danau Ngade pada tahun 2011. Walaupun menguntungkan secara ekonomi, namun informasi tentang biologi dan ekologi masih sangat kurang. Pertumbuhan dan sintasan merupakan dua faktor utama yang harus diketahui dalam pengembangan budidaya ikan patin. Penelitian ini bertujuan untuk mengetahui pertumbuhan dan sintasan ikan patin yang diberi jenis tepung ikan berbeda dalam campuran formulasi pakan buatan. 120 ekor ukuran fingerling ditempatkan pada 12 akuarium. Pakan buatan diformulasi menggunakan metode bujursangkar Pearson. Tiga penyumbang protein tepung ikan yang berbeda yaitu tepung ikan layang, tepung ikan nila, dan tepung ikan sidat dicampurkan pada formulasi pakan. Pakan komersial digunakan sebagai kontrol. Penelitian dilakukan secara eksperimen menggunakan RAL (Rancangan Acak Lengkap). Hasil penelitian menunjukkan uji daya apung berkisar 2 menit dan 23 detik hingga 3 menit 47 detik, dan daya tahan pakan di dalam air adalah 2 menit 09 detik hingga 2 menit 35 detik. Sintasan sebesar 100% kecuali pada perlakuan C. Laju pertumbuhan tertinggi berturut-turut pada perlakuan A (16,47%), B (15,85%), D (15,57%), dan C (7,00%). Penggunaan tepung ikan nila
Catfish (Pangasianodon hypothalamus) are known in Asia, specifically in Southeast Asia. Currently, this fish has been exported to almost all countries in the world. This research aimed to examine the existing conditions of the solid waste produced, analyze the chemical composition of the waste, and look for alternatives for the policy and economical use of waste in the catfish processing business. Using the survey method, data were gathered through measurement at the research location and laboratory, interviews with business owners, and field observations. Proximate analysis was conducted on pink slime meat, belly fat, bones, and fish innards. Analysis of acid number, saponification number, iodine number, and fat fatty acid was carried out on stomach fat. Meanwhile, amino acid analysis was carried out for pink slime meat. Handling catfish industrial waste has yet to be carried out properly, which causes a foul smell and disturbs the environment. The catfish industry waste’s chemical content (protein, fat, water content, carbohydrates, and fatty acids) (pink slime meat, belly fat, fish bones, and innards) is still relatively applicable. The study processed fish waste into products like instant porridge, analogous fish sago rice, and fish sago noodles. The proximate analysis results of these products show figures that exceed the minimum standards for similar products.
