EHP: The Persistent Nightmare Haunting Vietnamese Shrimp Farm 💤💣💥 📊 One major factor driving up the cost of shrimp production in Vietnam is the low success rate due to rampant disease outbreaks. Currently, the survival rate for super-intensive white leg shrimp farming in the country is less than 40%, significantly lower than competitors like Ecuador at over 90%, India at over 60% , and Thailand at 55%. Small-scale shrimp farms in Vietnam are essentially gambling 🎲- high risk, high reward —an environment that's becoming increasingly challenging as conditions deteriorate. Within just 30-45 days of stocking, shrimp are often infected with EHP (Eusoridacris hermaphroditus), leading to stunted growth and early mortality. ☠ Even those that survive this phase are frequently hit by secondary diseases like white spot syndrome, white feces, or pancreatic necrosis after 60 days. These recurring outbreaks leave farmers disheartened and erode their trust in the farming cycle. Unlike before, EHP-infected shrimp, despite their poor growth, continue to eat voraciously. This behavior can mislead farmers and lead to increased feed costs. Often, treatment efforts fail to deliver the expected results, adding further financial strain. 💬 Technical solutions for the Vietnamese shrimp industry exist but are still insufficient! What the industry needs now are #revolutions: revolution in the farmers' attitude towards sustainable farming, revolution in investment thinking for long-term benefits, and revolution in the policies controlling the quality of aquaculture drugs and feed. At Tepbac, we are dedicated to driving change every day !! By providing objective information, effective IOTs products, and reliable testing services, Tepbac is steadily helping shrimp farmers enhance production efficiency and protect their farming environments. ✊ Let's work together to make a historic change in Aquaculture!!! photo: Araujo, Joao and Hughes (2016)

Histamine Poisoning from Tuna 🍣🤢: What Need to Know and How to Prevent It Tuna, a popular ingredient in dishes like sashimi, sushi, and grilled tuna, can cause histamine poisoning if not properly handled. However, nothing can beat our passion for Tuna, that is why we need to educated ourselve with below knowledges: 🔍 Causes and Symptoms of Histamine Poisoning Histamine forms when bacteria break down protein histidine in tuna, especially if the fish is not chilled immediately after catching or is stored for too long. Symptoms of histamine poisoning include: Rash and itching  Headache and dizziness  Abdominal pain and diarrhea  Shortness of breath 📊 Toxic Levels of Histamine Histamine can be toxic when levels exceed 100 mg/100 g of fish. However, symptoms can occur even at lower levels depending on individual sensitivity. 💡 How to Prevent Histamine Poisoning Choose Reliable Sources: Purchase tuna from suppliers with strict handling and storage practices.  Check Storage Conditions: Tuna should be stored at temperatures between 0°C and 4°C or frozen immediately.  Inspect Smell: Fresh tuna should have a distinct sea-like smell, not a sour or off-putting odor.  Verify Expiry Date: Ensure the tuna is within its use-by date and has been properly stored. By paying attention to these factors, you can safely enjoy tuna and savor your favorite dishes without the risk of histamine poisoning ! #SeafoodSafety #HistaminePoisoning #Tuna #FoodQuality #HealthFirst #FoodSafety

Have you ever read the ingredient list of a Microbial product and felt confused by the long Latin names and their functions? Based on the first part of their names, we might get an idea of their roles through the following groups: #Bacillus_and_Lactobacillus These are two of the most commonly used microbial genera in aquaculture. Hundreds of strains from these two genera have been proven to have diverse functions, such as breaking down organic matter, reducing toxic gases in water, and enhancing gut health for aquatic animals. #Nitrosomonas_and_Nitrobacter These two genera of bacteria play a key role in the nitrification process, converting NH₄+ into NO₃-, helping to reduce toxic ammonium and create a safer environment for aquatic animals. They are recommended for use in ponds with large biomass or ponds that are not frequently water-exchanged. #Pseudomonas Pseudomonas has the ability to break down oil and hard-to-decompose organic substances, helping to clean the water environment and prevent pollutants from negatively affecting the ecosystem. Additionally, many Pseudomonas strains can inhibit disease-causing bacteria like Vibrio by producing natural antibacterial substances like siderophores, which compete for iron and limit pathogen growth. #Saccharomyces This yeast species improves digestion and supports overall health by providing digestive enzymes, while also enhancing immunity and reducing stress for farmed animals. Saccharomyces is particularly effective at absorbing toxins like mycotoxins and heavy metals in ponds. #Rhodobacter Rhodobacter is a group of photosynthetic bacteria capable of converting harmful sulfur compounds like hydrogen sulfide into non-toxic forms such as sulfate salts, helping to reduce odors and improve water quality, especially in closed ponds or earthen ponds with limited siphoning or water exchange. #Thiobacillus Thiobacillus helps oxidize sulfur and iron in the water environment, contributing to improved water quality by removing harmful compounds and enhancing the living conditions for aquatic species. Understanding the functions of these common microbial species not only helps farmers choose the right microbial products for their purposes, optimizing effectiveness, but also prevents falling for exaggerated or false advertising claims, avoiding waste, and ensuring timely management of arising issues! #Aquaculture #Shrimpfarming #EfficientBacteria

😲 Visiting the Water Treatment System at One of Vietnam Leading Hatcheries In SPF shrimp hatcheries, water treatment is crucial to ensure the shrimp are not infected by pathogens from the environment. At one of Vietnam’s leading hatcheries, the water treatment system is meticulously implemented with multiple filtration and treatment stages to remove bacteria, viruses, harmful algae, and protozoa. Let’s explore this process. 1. Coarse Sedimentation Pond Water from the natural environment, carrying organic debris and impurities, first flows through a channel into a large, deep pond. This pre-treatment step removes large suspended particles, reducing the amount of impurities that could affect later filtration stages. 2. Drum Filter After settling in the coarse pond, the water moves to a drum filter. This mechanical device removes smaller particles, such as remaining impurities from the sedimentation pond, making the water clearer before chemical treatment. 3. Chemical Treatment The water then passes through a cloth filter before entering the ready pond. Chemical treatment includes two main steps: Chlorine (for disinfection) and EDTA (for removing heavy metals). 4. Protein Skimmer To ensure the water is free of dissolved proteins and remaining organic matter, a Protein Skimmer is used. It generates tiny air bubbles that organic substances attach to, rise to the surface, and are then removed from the water. This helps eliminate small protein molecules, preventing bacterial and harmful algae growth. 5. Ozone Treatment Next, the water is disinfected with ozone, a powerful oxidizing agent that destroys any remaining microorganisms. 6. Ultrafiltration (UF) Finally, the water is passed through an UF system, using ultrafine membranes to remove all micro-sized impurities such as bacteria, viruses, and protozoa, ensuring the water meets SPF standards and is pathogen-free. Despite rigorous water treatment, pathogens can still enter through parent shrimp, natural feed, technicians, or the air. Should we tighten control over all risks or consider developing a diferent shrimp breeding model? photo source: fresh by designed, Tepbac

⚖ Comparison between Eyestalk Ablation and Non Ablation Methods in Shrimp Broodstock ✂ The Eyestalk Ablation method is a traditional technique applied to stimulate female shrimp to molt, quickly reach sexual maturity, and spawn. By removing part of the eyestalk, the production of reproductive inhibitory hormones is disrupted, thereby increasing the frequency of spawning. This method is technically simple and cost-effective, commonly used in medium and small hatcheries. However, it reduces the number of reproductive cycles in shrimp, leading to a gradual decline in egg quality and the health of the offspring over generations. Although accepted by certifications like ASC, BAP, etc., eyestalk ablation still raises animal welfare concerns in hatcheries. 🌱 The Natural Breeding method without eyestalk ablation is a new solution, allowing female shrimp to reproduce naturally by nutrition enhancing, thereby enhancing their resistance and extending their reproductive lifespan. Research shows that non-ablated shrimp can reproduce more frequently throughout their lifespan, producing healthier offspring with higher survival rates and lower disease incidence. Shrimp reared using this method yield more than 200 nauplii per mother, with shorter larval rearing times and stable, high-quality post-larvae with fewer deformities. Thus, transitioning to the natural breeding method without eyestalk ablation not only improves the quality of shrimp larvae but also contributes to the sustainable development of the shrimp farming industry. #eyestalk_ablation_method #natural_breeding_method

🛡 Preventing Disease Outbreaks: 4 Principles for Safe and Effective Antibiotic use 👑 In intensive shrimp farming, shrimp ponds are valuable assets for farmers. Therefore, when shrimp become ill, treatment must be conducted carefully and scientifically to ensure effectiveness and avoid harming the environment and human health. 🔍 When shrimp show abnormal signs such as reduced appetite, empty intestines, or lethargic swimming on the water surface, the first step is to identify the cause of the disease. 🔬 Diagnosis can be carried out at the farm or in specialized laboratories. The diagnostic steps include: observing the shrimp externally, measuring water quality, and examining shrimp under a microscope to detect bacteria, parasites, or fungi. If necessary, bacterial culture on petri dishes, PCR testing, or histopathological examination may be performed to obtain the most accurate diagnosis. After identifying the cause of the disease, the selection of antibiotics should follow these principles: 💊 Use antibiotics only for bacterial diseases: Antibiotics are ineffective against diseases caused by fungi, parasites, or viruses. Antibiotics should be used for treatment, not for prevention. ⭕️ Choose the appropriate antibiotic: The selected antibiotic must be cost-effective, not on the list of prohibited drugs, and readily available on the market or in stock. 🎯 Proven treatment efficacy: Avoid using antibiotics indiscriminately or combining multiple antibiotics from the same group. Studies show that 87% of bacterial samples found in ponds carry drug-resistant or multi-resistant genes. Therefore, it's necessary to use antibiotic susceptibility testing to determine the most effective antibiotic against the bacteria causing the disease in the pond. 📝 Follow the correct dosage and withdrawal period: Antibiotics must be used at the correct dosage, for the appropriate number of days, and adhere to the withdrawal period of that antibiotic before harvesting to ensure safety for consumers and the environment.

Seafood Survey Reveals Surprising Consumer Insights: Price Overrules Sustainability, Health Concerns, and Certification Trust This January, a consumer survey involving over major seafood-importing markets in Europe, North America, East Asia, and Australia was conducted by the Aquaculture Stewardship Council (ASC) and Conversation Studio - Proposition Design. This research revealed the following key findings: Consumers Are Price-Driven: 58% of consumers are concerned with price and promotions when shopping, more than factors like quality, brand, ingredients, packaging, and product origin. Sustainability Is Seldom Considered: Although 67% of respondents said sustainability is important, only 1-2% actually consider this factor when purchasing seafood and groceries. The main reasons they choose sustainable seafood are for health safety and environmental benefits. Free from antibiotics and chemicals is most concerned when speaking of sustainable seafood. Consumers Are Eating Less Fish/Seafood: 16-17% of survey participants have reduced their consumption of sweets and red meat, 8% have reduced their fish/ seafood intake, while 22% have increased their consumption of vegetables and 15% have increased their fruit intake. This shift may be due to price concerns and health issues. The Distinction Between Farmed and Wild-Caught Fish Is Unclear: Only 33% of consumers believe they are knowledgeable about this issue. Consumers think wild-caught seafood is healthier, less polluted, more natural, and tastier; however, they are also concerned about the higher prices and overfishing. 44% prefer eating wild-caught seafood, and 37% are fine with eating farmed seafood. Independent Certification Programs Are the Most Trusted Source of Information: Consumers trust independent certification programs more than any other source of information when evaluating the sustainability and safety of seafood. Recognition and trust in the ASC are significantly higher compared to other farmed seafood certification logos, associated with concepts of responsibility, sustainability, quality, safety, and health.
