Microalgal bioremediation of recirculating aquaculture system (RAS) wastewater represents an alternative for treatment with the potential to generate valuable biomass. This study evaluated effects removing biological contamination and suspended solids from Nordic area RAS through filtration 0.45 μm filters on performance nutritional value microalgae. All three tested green microalgae (Haematoco...

Recirculating aquaculture systems (RAS), often used in fish farming, rely on microorganisms to maintain healthy water quality, nutrient cycling, animal welfare, and disease control. However, many daily operations farms (e.g., stocking) may negatively affect the microorganisms' community composition create a favorable environment for opportunistic pathogens. Currently, understanding communities ...

The effects of ultrafine bubbles on the high stock density striped catfish larvae in a recirculating aquaculture system (RAS) are described this research (UFBs-RAS). In study, various densities were investigated regarding effect oxygen saturation yolk sac absorption rate, length growth and utilization efficiency at endogenous stage. survival specific rate (weight, length, biomass), gross feedin...
