Summary: The innate immunity of invertebrates is a valuable foundation for studying the common biological responses to environmental changes. The intensification of aquaculture has led to the overuse of antibiotics and chemotherapeutics, resulting in the emergence of resistant microbes. Biofloc technology (BFT) offers a sustainable and eco-friendly approach to disease management in aquaculture by harnessing the power of antibiotics, probiotics, and prebiotics.

Summary: By optimizing stocking density of koi carp with gotukola in a phytoremediated aquaponic system, it was found that the best results were achieved with a stocking density of 1.4 kg m(-3) (T1), although 2.1 kg m(-3) (T2) also showed good performance. Different densities had significant effects on the growth and health status of koi carp.

Summary: The study found that maintaining low stocking densities within lantern nets is crucial for promoting scallop growth, particularly during periods of high temperature and growth. During summer, scallop growth rates were significantly higher in low-density nets compared to high-density nets. Additionally, there were significant nonlinear relationships between temperature, stocking density, and shell height growth rate, with optimal growth occurring within a window of 10-15 degrees Celsius.

Summary: In order to optimize the integrated multi-trophic aquaculture (IMTA) model, this study investigated the effect of Bellamya purificata cultivation on the dynamics and assembly of bacterial communities in sediment. The results showed that B. purificata significantly altered the composition and function of bacterial communities in sediment, with different effects at different stocking densities. B. purificata cultivation also resulted in changes in environmental factors, which were closely related to the altered composition and function of bacterial communities. Stochastic processes dominated the bacterial community assembly in the sediment and B. purificata cultivation had limited impacts on the bacterial community assembly.

Summary: Fish farming in Recirculating Aquaculture Systems (RAS) is a sustainable and efficient practice. This study analyzed the influence of different stocking densities on the water microbiome composition and identified bacterial pathogens associated with common fish farming practices. The results showed that microbiomes differ across systems and sampling points, and fish biomass and water physicochemical properties affect the microbiome.

Summary: Cholesterol homeostasis is crucial for skeletal development, and dysregulation in cholesterol-related mechanisms can lead to cartilage diseases like osteoarthritis (OA). Studies have linked elevated serum cholesterol levels to OA, and abnormal lipid accumulation in chondrocytes due to disrupted cholesterol homeostasis has been implicated in OA development. However, the precise mechanisms linking cholesterol metabolism, particularly HDL cholesterol metabolism, to OA remain unclear, and further research is needed to uncover new therapeutic targets for OA patients.

Summary: The demand for fish in Tanzania is increasing due to population growth and rising incomes, but the decline in wild fish catches has created a supply gap. Aquaculture provides a viable alternative to meet the fish demand gap. However, despite the perfect climate and land for fish farming in Tanzania, the potential of aquaculture is not fully tapped. This study assesses the growth of aquaculture in Dodoma, Tanzania, and identifies its potential, challenges, and solutions.

Summary: This study investigates the physiological responses of catsharks to air exposure and identifies specific enzymes involved in amino acid catabolism and ammonium excretion. The study demonstrates that catsharks rely on white muscle amino acid catabolism to meet the energy demand during stress and utilize a Na+/H+ exchanger enzyme for ammonium excretion. Understanding the relationship between acute stress and osmoregulation in elasmobranchs is important for studying these ancient vertebrates.
