Could farmed #salmon become #vegetarian? 🤔 🐟 World's first #genetic overview of Atlantic salmon gut #microbiota could pave the way for switch to plant-based #aquaculture feed, according to researchers. 🔬 The groundbreaking research, led by researchers at NMBU - Norwegian University of Life Sciences and published in Nature Microbiology, offers critical insights into how gut #microbes help salmon digest #nutrients, studying 211 types of microorganisms from both wild and farmed salmon. 💬 “Before introducing plant-based feeds, we need to understand what happens inside the salmon’s gut to optimize the nutritional benefits,” said lead researcher, Sabina Leanti La Rosa. "This knowledge could lead to innovations in aquaculture and the development of new, more effective feeds for better #fishhealth, #sustainability, and #nutrition in #farming systems," 💡 Read more details here 👉 https://lnkd.in/d_s5MbWS

🐟 #FishHealth Matters! 💡 Ensuring the health of wild and farmed fish is fundamental for sustainable #aquaticecosystems. One key aspect is checking their #blood health, particularly looking at #poikilocytosis – which means finding abnormally shaped #RedBloodCells. 🤔 Why does it matter? ✔ #Poikilocytosis can indicate #stress, #infections, #poor nutrition, or pollution. ✔ Different shapes of these cells, like #acanthocytes or #spherocytes, show various health issues. ✔ Piscine poikilocytosis as a significant fish #hematological biomarker 🔔 Understanding these changes helps researchers and #vets spot problems early and take action. 👉 Reading the comprehensive review from Dr. Avishek Bardhan, Prof.  Thangapalam Jawahar Abraham, Dr. Ratnapriya Das, and Dr. Prasanna kumar Patil from The Neotia University, West Bengal University of Animal and Fishery Sciences, and Central Institute of Brackishwater Aquaculture CIBA(ICAR), India. https://lnkd.in/gexDbqnX

Infectious diseases can be a complicated matter, especially in RAS. We are happy to share our work which provides a powerful tool to assist in solving complex diagnosis in aquaculture farms, recently published in Scientific Reports. We (Argelia Cuenca, Niccolò Vendramin, Lone Madsen and I) will be at #Aqua2024 conference in Copenhagen later this month, reach out if you have are interested in knowing more about it.   In this study, we tested the use of a microfluidic High Throughput qPCR chip to monitor and quantify all most important bacterial and viral salmonid pathogens during a 7 month survey in a RAS farm with severe accumulated mortality. Results were compared and validated against standard diagnostic and provide valuable insights in the pathobiome involved in complex disease in RAS. https://lnkd.in/dy_5ahK6   #AquacultureEurope #WorldAquacultureSociety #EuropeanAquacultureSociety #Copenhagen2024

i rarely post on Linkedin , but in my honest opinion, this work deserve the attention of the fish health community! Together with Juliane Sørensen Argelia Cuenca, Lone Madsen and many other good colleagues we have first explored pathobiome of RAS farm describing occurrence of putative new gill pathogens in Rainbow trout. Then, based on this knowledge, we prototyped and tested in the field a microfluidic High Throughput qPCR chip to describe the kinetics in pathogens load over an outbreak and understand disease progression and development. All the work done always comparing with standard diagnostic for ensuring results validation. This high throughput tool has a lot of interesting potential for improving fish health and disease diagnostics in aquaculture!

#Aquaculturedisease101 series Early detection is key to successful disease management. These fish are showing signs of gill irritation triggered by deterioration in water quality and development of bacteria biofilm* on their gills. *mats of Tenacibaculum in marine fish or Flavobacterium aka columnaris disease in freshwater fish If caught early, response to a mucolytic such as benzalkonium chloride or F10 short bath is good. However, the ability to catch it early is limited by ability to see subtle changes in fish behaviour in commercial aquaculture. Reduction in feed resulting in increase in uneaten feed or clogging of drum filters by faeces may cause poor water quality that triggers increased mucus production in gills, predisposing to bacteria overgrowth. The deterioration in water quality may in itself trigger bacteria biofilm formation on gills. This is where AI to better capture these changes and alert farm staff to carry out mitigation procedures to correct these triggers of gill bacteria overgrowth will prevent the disease from progressing to death. Heavy mats of filamentous bacteria interfere with oxygen uptake in gills. Bacteria also produce enzymes that destroys gill tissues. #aquaculture #disease #waterquality #bacteria #gills

👉Do you know the causes of fungal and bacterial infection in the hatchery 🐟🐟?? The following are the causes of fungal and bacterial growth in the hatchery * fungus and bacteria can be introduced from water contamination * also when the Hatchery system do not circulate well water and lead fish eggs to compact, these can lead to eruption of this infections * sometimes unfertilized eggs in the incubator, on the way to decaying or rotting can provide favourable condition to growth of pathogens, so means if these are not removed on time can infect the health eggs.🐟 👉So in controlling these infections most farmer apply chemical treatment like use of formalin, methylene blue and humic acid, which are cost full especially for the ones that have large scale production. But am doing a research on natural alternative way of controlling bacterial and fungal infections so as to reduce cost to the farmers which is using of almond leaves 🌿🌿 in treating fungal and bacterial in Nile tilapia eggs and other fish. 👉Here are importance of almond leaves to the Hatchery system, first of all it produce tannins that have antimicrobial agents (flavonoids)which help to kill the pathogens (bacterial and fungal infections caused by Trichodina sp and saprolegnia sp). but also tends to lower the pH level in the water which create unfavorable condition to these bacteria and fungi. # Aquaculture sector # hatchery system, Nile tilapia follow for more

Antimicrobial resistance (AMR) is a significant threat to global public health. There is a direct relationship between antibiotics and the emergence of AMR in fish and human infections✅〽️ Studies have highlighted that bacteria may convey resistance genes to the next generation. Another research suggests that the development of AMR in aquaculture environments may lead to AMR in bacteria or human diseases💯💥Therefore, it is essential to identify the trends of AMR in fish to develop better surveillance strategies for the future🐟 #antibiotics #AMR #Aquaculture #SDG2 #SDG14 #publichealth

As a part of RAWEP. We visit the host farmer field I obversed this disease in the field STEM ROT OF PADDY Casual organism: Sclerotium oryzae Symptoms : Stem rot in paddy, caused by Sclerotium oryzae, can be highly damaging, especially under waterlogged conditions. Here are the precise symptoms: 1. Initial Lesions: Dark brown or black lesions appear near the waterline on the outer leaf sheath during the tillering to panicle initiation stages. These lesions are typically small, irregular, and dark, gradually enlarging. 2. Stem and Sheath Decay: The lesions spread to inner sheaths and eventually to the stem, causing tissue decay. As the disease progresses, these spots turn necrotic, and the stem becomes weakened. 3. Inner Stem Damage: The fungus can penetrate into the stem, causing internal rotting. Infected stems often hollow out, making the plant brittle and prone to lodging (falling over). 4. White Mycelial Growth: In humid conditions, a whitish fungal growth appears on the infected tissues, sometimes accompanied by small, black sclerotia (fungal survival structures) on the surface of the stem or sheath. 5. Stunted Growth: The plant may show stunted growth, yellowing, and wilting due to disruption in nutrient and water transport. The damage often worsens post-heading, affecting grain filling and yield. 6. Lodging: Severe infection leads to lodging, especially near harvest, which complicates harvesting and reduces grain quality Control Measures: 1. Cultural Practices: Manage water levels, remove infected debris, and use crop rotation to reduce fungal spread. 2. Resistant Varieties: Promote use of resistant paddy varieties to minimize infection. 3. Biological Control: Apply bio-agents like Trichoderma and organic amendments to suppress the pathogen. 4. Chemical Control: Use fungicides (e.g., propiconazole) carefully and only when necessary. 5. Farmer Training: Conduct demonstrations and training to increase awareness of integrated control methods and sustainable practices. . . . . . . #organic #farmer #naturalfarming #pathology #crop #stemrot #ipm #rawep #farm #paddy #diease #agriculture #farming
