The tiger shrimp Penaeus monodon is a commercially important species; however, the intensification of farming this species has led to production and release significant amounts organic waste. Traditional aquaculture uses water exchange for waste removal, which may cause pollution infection reared with external pathogens. This study aimed evaluate effects two different modes on antioxidant status, nonspecific immune response, growth performance P. monodon, reveal differences in their microbial communities. experiment was divided into groups: one using bioflocs zero (Group ZC), other clear system C). results showed that, compared those Group C, ZC exhibited higher final body weight, lower feed conversion ratio, survival rate, unit yield. Additionally, digestive enzyme activities, as well upregulated expression immune-related genes (such lysozyme, anti-lipopolysaccharide factor, Toll-like receptors). Therefore, biofloc technology can improve performance, immunity, capacity offering an environmentally friendly efficient model farming.

Cyanobacteria, also known as blue-green algae, are a diverse phylum of photosynthetic, Gram-negative bacteria and one the largest microbial taxa. These organisms produce cyanotoxins, which secondary metabolites that can have significant impacts on both human health environment. While toxins like Microcystins Cylindrospermopsins well-documented been extensively studied, other including those produced by Lyngbya Nostoc, remain underexplored. lesser-known cause various issues in humans, neurotoxicity, hepatotoxicity, dermatotoxicity, each through distinct mechanisms. Moreover, recent studies shown cyanobacteria be aerosolized transmitted air over long distances, providing an additional route for exposure to their harmful effects. However, it remains area requires much more investigation accurately assess risks develop appropriate public guidelines. In addition direct toxins, lead algal blooms, pose further wildlife health, global concern. There is limited knowledge about these highlighting need research understand clinical manifestations improve society’s preparedness associated risks. This work aims review existing literature underexplored with intoxication, elucidate relevance, address challenges cyanobacterial research, provide guidance mitigating adverse
