Abstract Selenium plays a crucial role in vital physiological processes for fish, by involved many of cellular metabolism and increase the growth performance health status fish. Nano-selenium (nano-Se) has been shown to promote fish more than other traditional inorganic Se forms. Additionally, increased capacity absorb various nutrients, provided protection from pathogens. In general, growth, hematological, biochemical immune characteristics improved with incorporation dietary selenium. When fed small amounts, can also function as an antioxidant. There is need research on use supplement diets aquatic species since there are few variables that could affect levels make it difficult estimate its required levels. The actual bioavailability nanoparticles needs be determined. This review have tried evaluate draw conclusions about advantages forms potential application mineral animal’s different biological functions.

Abstract Measuring and monitoring fish welfare in aquaculture research relies on the use of outcome- (biotic) input-based (e.g., abiotic) indicators (WIs). Incorporating behavioural auditing into this toolbox can sometimes be challenging because sourcing quantitative data is often labour intensive it a time-consuming process. Digitalization process via computer vision artificial intelligence help automate streamline procedure, gather continuous optimisation assist decision-making. The tool introduced study (1) adapts DeepLabCut framework, based machine learning, to obtain pose estimation Atlantic salmon parr under replicated experimental conditions, (2) quantifies spatial distribution through metrics inspired by ecological concepts home range core area, (3) applies inspect variability around feeding. This proof concept demonstrates potential our methodology for automating analysis behaviour relation including detection, variations within between tanks. impact feeding these patterns also briefly outlined, using 5 days as demonstrative case study. approach provide stakeholders with valuable information how their rearing environment small-scale settings used further development technologies measuring future studies.
