“…Transcriptome analysis of the spleen of A. dabryanus also revealed upregulation of immune‐related signalling pathways after feeding different fat sources for seven weeks (Chen et al . 2019b). Differentially expressed unigenes revealed enriched pathways mainly related to the immune system, with NOD‐like receptor signalling, platelet activation, Fc gamma R‐mediated phagocytosis, Th17 cell differentiation, and Th1 and Th2 cell differentiation among the most important ones.…”

Sturgeon immunity is relevant for basic evolutionary and applied research, including caviar-and meat-producing aquaculture, protection of wild sturgeons and their re-introduction through conservation aquaculture. Starting from a comprehensive overview of immune organs, we discuss pathways of innate and adaptive immune systems in a vertebrate phylogenetic and genomic context. The thymus as a key organ of adaptive immunity in sturgeons requires future molecular studies. Likewise, data on immune functions of sturgeon-specific pericardial and meningeal tissues are largely missing. Integrating immunological and endocrine functions, the sturgeon head kidney resembles that of teleosts. Recently identified pattern recognition receptors in sturgeon require research on downstream regulation. We review first acipenseriform data on Toll-like receptors (TLRs), type I transmembrane glycoproteins expressed in membranes and endosomes, initiating inflammation and host defence by molecular pattern-induced activation. Retinoic acid-inducible gene-I-like (RIG-like) receptors of sturgeons present RNA and key sensors of virus infections in most cell types. Sturgeons and teleosts share major components of the adaptive immune system, including B cells, immunoglobulins, major histocompatibility complex and the adaptive cellular response by T cells. The ontogeny of the sturgeon innate and onset of adaptive immune genes in different organs remain understudied. In a genomics perspective, our new data on 100 key immune genes exemplify a multitude of evolutionary trajectories after the sturgeon-specific genome duplication, where some single-copy genes contrast with many duplications, allowing tissue specialization, sub-functionalization or both. Our preliminary conclusion should be tested by future evolutionary bioinformatics, involving all >1000 immunity genes. This knowledge update about the acipenseriform immune system identifies several important research gaps and presents a basis for future applications.

“…With increasing urbanization and deforestation, the impact on environmental protection seems to hinder the availability of natural resources as well as sustainability of aquaculture industry (Chen et al 2019). This rising pollution level poses a huge threat on the water quality index due to the pragmatic contamination of metals, pesticides, aromatic polycyclic hydrocarbons, microplastics, and antibiotics which affects the life cycle of aquatic species.…”

With decreasing world oceans fish stock there is rapid increase in aquaculture production. To meet this demand, there is an urgent need to improve existing aquaculture technologies and make the system more sustainable and economically feasible. Diatoms are unicellular protists that are present ubiquitously in freshwater and marine habitats and are responsible for 40% of marine and 20% of net global primary productivity. They are the most preferred microalgae for production of live feeds in mariculture due to their suitable size, easy digestibility, and optimum nutritional content. Diatoms biosynthesize a range of bioactive compounds like lipids, polysaccharides, proteins, pigments, and vitamins which can both promote the health and survival of aquatic species like fishes, bivalves, and shrimps. As the main prerequisite to attain sustainability is to reduce pollutants from aquaculture wastewater, diatoms have long been employed for remediating and utilizing the eutrophic nutrients as a growth supplement which otherwise might be detrimental to aquaculture species. Though many recent studies have highlighted the significance of diatoms in aquaculture, its dual contribution in maintaining the nutritional content of the feed as well as in improving the water quality should be coupled with its unique mechanisms and adaptability. Thus, the current review addresses the bottlenecks in aquaculture industry and the prospects of implementing diatom‐based bioremediation and biomass valorization for the production of live feeds with the hindsight of establishing circular bioeconomy.

The application of microalgae biotechnology, which can recover nutrients from wastewater, improve water quality, and feed some aquatic animals, is becoming an emerging trend in the development of eco-friendly aquaculture. Previous studies explored a variety of models to support the use of microalgae in aquaculture practice, verifying the feasibility and advantages of microalgae-based aquaculture. However, a couple of bottlenecks and problems jeopardizing the application of microalgae biotechnology in aquaculture are discovered in the research and industrial practice. This work, hence, summarizes the research progress and the current opinions relating with the microalgae-based aquaculture and proposes some critical thoughts about the bottlenecks challenging its industrial implementation.
