“…The improvement resistance against Aeromonas hydrophila in a biofilm-based rearing system was observed in common carp fry (Joice et al, 2002) and in Rohu, Labeo rohita (Rajesh et al, 2008). Similarly, Vinay et al (2019) observed an elevated level of immunity of Pacific white shrimp, L. vannamei, by oral administration of Vibrio harvei biofilm. Among some exvivo studies, Lee et al (2017) demonstrated that dietary inclusion of freeze-dried biofloc powder at the level of 4.0% increases innate immunity in Pacific white shrimp.…”

During the last few decades, aquaculture as a useful animal protein providing sector intensifies to meet the growing world population demands. Although fish culture technological advancement has resulted in increased production, intensive technology has negatively affected the environment—consequently, aquaculture research efforts have been diverted towards developing sustainable culture technology. Introducing algae and bacteria singly or in combination in aquaculture was advantageous both by ex-vivo and in-vivo culture techniques. Utilization of microbial consortium in aquaculture can help to construct three pillars (social, economical, and ecological) of sustainability by improving water quality, reducing dependency on a wild fish stock as a feed ingredient, improving the health status of animals, and increasing economic returns along with protection of the environment. Numerous fruitful research outcomes on using algal-bacterial systems are available for its application in aquaculture. In this context, the present article highlights an updated review of current research trends on various aspects such as application of algal-bacterial consortia for aquaculture, available technologies based on their interaction, and recommendations for further improvement. This review will also provide some critical clues for the standardization of novel fish culture techniques based on microbial interaction.

“…The proper prevention of diseases in shrimp farming is indispensable. Efforts to prevent shrimp diseases can be made by modulating immune responses using immunostimulants, vitamins, and hormones (Kilawati & Islamy, 2021;Vinay et al, 2019). Immunostimulants are chemical compounds, drugs, or other materials that enhance non-speci c response mechanisms.…”

Immunostimulants are more suitable for improving the health of shrimp than using drugs in the prevention of diseases. This study evaluated the efficacy of bioactive compounds from Ocimum basilicum and Piper betle in increasing the non-specific immune response of Litopenaeus vannamei. Samples were collected directly from a traditional market. Shrimp was fed: O. basilicum leaf flour- and P. betle leaf flour-un-supplemented diet (P1), O. basilicum leaf flour (44.84 g/kg feed)-supplemented diet (P2), P. betle leaf flour (31.57 g/kg feed)-supplemented diet (P3), and O. basilicum leaf flour (22.42 g/kg feed)- and P. betle leaf flour (16.79 g/kg feed)-supplemented diet (P4). Phytochemical screening tests were conducted using commonly used chemical reagents, including Dragendorff, Meyer, and Liebermann-Burchard reagents. Supplementation with O. basilicum and P. betle (P4) significantly enhanced the shrimp’s immune response, namely the total hemocyte counts (THC), phagocytic activity (PA), phagocytic index (PI), and prophenoloxidase (proPO). The supplemented diet (P4) was synergistically able to improve shrimp health, with the highest values for THC (7.30 x 106 cells/mL), hyaline (61.33%), PA (84%), PI (2.19), and proPO (0.91). Flavonoids and alkaloids in the feed containing leaf flour from both plants were bioactive compounds suspected to be responsible for enhancing the immune response. These findings suggest that a leaf flour combination of O. basilicum and P. betle can be a new immunostimulant alternative to improve shrimp health for disease prevention.

“…The diseases may cause vasculitis, gastroenteritis, eye lesions, and even death. Considering the high economic losses in aquaculture and the high mortality rates, studies have been conducted on the genetics, physiology, and pathophysiology of V. harveyi (Vinay et al, 2019; Zhang et al, 2021). Despite this, it is still unclear what pathogenic mechanisms this bacterium uses to cause disease.…”

Caspases, also known as cysteine-dependent aspartatedirected proteases, play an important role in regulating apoptosis during development and inflammation. In this study, 10 caspase genes were characterized by searching the Japanese pufferfish genome using various bioinformatics methods, such as multiple sequence alignment and phylogenetic analysis. Additionally, we characterized the caspase genes and examined the expression profiles of every member in both healthy tissues and tissues infected with Vibrio harveyi in the liver and intestine. Our results revealed that 10 caspase genes were detected in all examined tissues, and the expression levels varied among different tissues and genes. Vibrio harveyi infection induced significant changes in the expression of 10 caspases in a time-dependent manner, suggesting that they might play
