“…Moreover, vitamin C supplementation was found to quicken the phagocytic infiltration rate, thus resulting in minimal lesion at the injection site and culminating in complete resolution on day nine following the challenge test [315] . Similarly, supplementing vitamin C was found to effectively reduce the mortality rate of Wuchang bream (Megalobrama Amblycephala) [316] and striped catfish (Pangasianodon hypophthalmus) [317] when confronted with A. hydrophila. Besides, cholecalciferol, the inactive form of vitamin D3, has been proven as an ideal feed additive for Atlantic Salmon (Salmo salar), particularly to harness its effect in resisting Aeromonas salmonicida infections [318] .…”

As feed accounts for a significant proportion of a farm’s expenditure, animal nutrition is one of the key profit determinants. Attributed to the size-dependent market value, enhancing shrimps' growth is essential to maximize profit. Despite not being the best option, antibiotics are often used as growth-promoting agents in farming. Although this trend is less explicit in aquaculture, increasing production yield is paramount, especially when intensive aquafarming compromises animal growth and increases disease prevalence. However, the environmental and clinical pitfalls of indiscriminate antibiotic usage are surfacing. Fortunately, increasing evidence demonstrated probiotics as a safer, more sustainable, and environmental-friendly substitute for antibiotics. Nonetheless, most studies are observational, and the growth-promotion mechanisms of these agents are yet to be elucidated. In this light, this review aims to decipher the growth promotion mechanisms of probiotics in shrimps based on the primary works conducted. Evidently, probiotic treatment modulates the gut microbiome composition. The growth promotion effect of probiotics is partly mediated through the production of bioactive compounds such as short-chain fatty acids, vitamins, and polyamines. Besides, elevated digestive enzyme activities following the introduction of probiotics may help enhance digestibility and utilization. Histological changes at the hepatopancreas and intestine were evident. Furthermore, probiotics may reinforce the protective mechanisms in the gut and strengthen immune function. Treated shrimps demonstrate better appetite and exhibit superior metabolic and growth-related genes profile. Contrasting these recognized mechanisms with antibiotics helps construct the initial framework for designing high-quality probiotics for growth enhancement in farmed animals.

“…Các cơ quan miễn dịch, chẳng hạn như tỳ tạng, gan và thận của cá bị nhiễm A. hydrophila thường biểu hiện các khuyết tật bệnh lý, bao gồm các thay đổi thoái hóa, hoại tử, phù nề và tình trạng xuất huyết (Chen et al, 2014;Abdelhamed et al, 2017;Sellegounder et al, 2018;Aisiah et al, 2020). Trong quá trình phòng chống bệnh lâu dài cho cá, khả năng miễn dịch của cá cần được nâng cao (Tang et al, 2017;Daniel et al, 2021). Hình 9 cho thấy rằng các chủng vi khuẩn A. hydrophila này thể hiện tính nhạy rất cao với các kháng sinh ciprofloxacine, norfloxacine, cefotaxime, enrofloxacine, flumequine và florfenicol (100%).…”

Nghiên cứu được thực hiện nhằm tìm hiểu mầm bệnh vi khuẩn và ký sinh trùng gây bệnh trên lươn giai đoạn giống và nuôi thương phẩm. Mẫu lươn được thu từ tháng 12/2021 đến tháng 08/2022. Kết quả ghi nhận có 6 giống trùng thuộc ngành giun sán ký sinh trong ruột lươn gồm: Camalanus, Carassotrema, Caryophyllaeus, Clonorchis, Pallisentis và Proteocephalus. Không tìm thấy ký sinh trùng trên lươn giống. Đối với lươn nuôi thương phẩm, giống giun tròn Camalanus có tỷ lệ nhiễm cao nhất (38,9%). Giống sán dây Caryophyllaeus có tỷ lệ nhiễm thấp nhất (23,3%). Kết quả phân tích lươn bệnh cho thấy vi khuẩn được phân lập phổ biến nhất trên các mẫu thận của lươn bệnh. Các dấu hiệu bệnh đặc trưng bao gồm: bụng trương, hậu môn đỏ, sưng to, da có những mảng trắng, xuất huyết, lỡ loét, gan, thận, tỳ tạng đỏ bầm, mềm nhũn. Kết quả định danh bằng kit API 20E đã xác định loài vi khuẩn Aeromonas hydrophila. Kết quả kháng sinh đồ cho thấy các chủng A. hydrophila nhạy rất cao với các kháng sinh ciproloxacine, norloxacine, cefotaxime, enroloxacine, flumequine và florfenicol.

“…Physiological and metabolic conditions of animals, including fish, can be diagnosed using biochemistry and blood components. In pangas species, previous researches have examined the probiotics; different dietary proteins and nucleotides sourced [16,[17][18][19], hematological and clinical parameters of stress study [20], infection [21], and use of immunostimulants [22]. Due to a lack of physiological and biochemical data, it is difficult to assess a species' health and manage its diseases.…”

In freshwater fish culture, water quality poses a serious hazard to survival and growth. To understand this high-risk factor associated with the poor water quality in the aquarium system, the hematological, histological, immunological, antioxidant, and growth performance of C. auratus, C. carpio, and P. hypophthalmus in the aquarium with different water treatment efficiencies and one without water filtration were compared. The experiment was conducted for approximately 120 days using water treatments: 1. PF, 2. BF, 3. PBF, 4. PBUVF, 5. WoF. Results showed that Fish health concerning turbidity (98%) was significantly reduced during post-filtration (PF, BF, PBF, and PB-UV-F) (p<0.05). In experimental tanks, water-treated fish showed improved growth and a 90% survival rate (p<0.05). In pot and bamboo filters, the hematological parameters such as RBC (93%, 94%, and 93%), WBC (79%, 18%, and 91%), and MCHC (93%, 45%, and 90%) were in the optimum levels during post filtration experiment. The immune response (IgM, C3, C4, NOS, and LSZ) of enzyme activities in the gut and liver of aquarium fishes and antioxidant parameters in the gut and liver (ABTS, CAT, GR, SOD, and LPO) were also the low-risk level where the water treatments in the aquarium tanks. In conclusion, our findings show that installing filtration systems in freshwater fish culture has helped to successfully regulate the fish health and water quality of aquariums and ensure their proper maintenance.
