Cell survival or death is a critical issue in the inflammatory response. Accumulation of ROS involves ROS generation and scavenging, which determine ROS homeostasis. Understanding the roles of ROS in modulating the inflammatory response in fish is vital for helping protect fish from the damage of water pollutants in harsh environmental conditions. ROS-related key genes and signalling pathways are relatively conserved in fish but vary among different species. Recent frequent incidences of fish diseases have posed a considerable challenge to large-scale aquaculture. ROS is important in stress perception, integration of diverse stress-responsive signalling networks, and activation of animal defence mechanisms, which frequently occur during inflammation in fish. This review summarises recent studies on ROS signalling pathways during inflammation in fish. Furthermore, it examines the relationship between ROS and inflammation in fish.

Plants are not optimal due to low protein content and antinutritional factors which can cause gut dysbiosis. Duckweed (<i>Lemnaceae</i>) is a family of aquatic plants with high protein content and has been used successfully for various types of animal feeds. In this systematic review and meta-analysis of 58 papers, we summarize the extent by which duckweed has been used in fish production including the species of fish tested, the grow-out stage of fish, and method of application. Duckweed studies spanned a total of 18 species of fish (16 freshwater and two marine) that collectively are valued at 263 billion USD annually, and comprise 28% of total aquaculture production by mass. The average experiment length was 72 days (SD 42), primarily at the fingerling life stage.

The <i>Lemna</i> spp., dominated by <i>L</i>. <i>minor</i>, <i>L</i>. <i>gibba</i>, and unknown <i>Lemna</i> species, were the most commonly used for feeds. <i>Spirodela polyrhiza</i> was the second most common.

However, these intensive fish farming practices can contribute to eutrophication, leading to changes in primary producers and promoting the excessive proliferation of cyanobacteria. Cyanobacteria blooms pose significant consequences to aquatic ecosystems, including potential risks to fish exposed to harmful cyanobacterial metabolites. Cyanobacterial metabolites encompass various chemical classes, such as terpenoids, carotenoids, alkaloids, cyanopeptides, amino acids, organophosphates, macrolides, and lipopolysaccharides. Some of these compounds' toxicity and impact on fish farms still need to be better understood. Cyanotoxins and off-flavour compounds in fish farms can pose risks to water and fish quality and potential health hazards for humans throughout the food chain.

Thus, a systemic review and meta-analysis were conducted to compare the impacts of various plant protein sources on growth, feed utilization efficiencies, blood lipid, and liver health of representative carnivorous species. Supported by the data from 256 articles, our results indicated that Atlantic salmon, African catfish, Black seabass, and Hybrid striped bass were better at utilizing plant protein sources than Grouper and Japanese seabass. Cottonseed and lupin proteins were promising protein alternatives, while rapeseed showed significant growth suppression effects for these carnivorous fish species. Besides, deep processing methods such as fermentation and enzymolysis alleviated undesirable consequences effectively when less than half of FM was replaced by plant protein sources. Moreover, the optimal plant protein sources are discussed for each fish species.

Despite success, selective breeding programs have limitations to the rate of genetic gain they can achieve. The incorporation of targeted genetic technologies, such as gene editing, into research related to selective breeding programs will help identify specific genes related to commercially desirable traits, as well as expedite genetic improvement.

Increased intensification and production of larger smolts in modern salmonid aquaculture has resulted in reports of gill NKA activity being less reliable as a proxy for smolt quality. Consequently, changes in mRNA <i>nka</i>-<i>α1b</i>/<i>α1a</i> ratios in gills are increasingly used as indicators of PST.

During PST, the osmoregulatory transformations necessary for SW tolerance and survival does not only occur in the gills. Equally important are the changes in ion transporting activities, including NKA activity, in the intestine and kidneys.
