Special Issue Information

Dear Colleagues,

Water quality can influence the structure and function of freshwater or marine ecosystems, especially the biodiversity and health of aquatic organisms. In turn, aquatic organisms are critical for improving water quality through elemental cycling and nutrient transformations. Further studies are needed to explore the role of organisms in the aquatic environment, which would enable us to better protect and restore aquatic ecosystems and improve the ecosystems’ health.

Aquatic organisms can reduce the negative impact of a wide range of pollutants on ecosystems. Aquatic plants (macro- and micro-algae), cyanobacteria, fungi, bacteria, and aquatic animals (shellfish and fish) have an important role in treating various polluted waters. Thus, aquatic organisms are one of the most environmentally safe, highly sustainable, and effective biomaterials. Biological methods for wastewater treatment have great potential for water quality control.

This Special Issue aims to understand the interplay between aquatic organisms and water quality and explore novel biological techniques for water quality treatment.

In this Special Issue, original research article and review are welcome. Research topics may include (but are not limited to) the following:

Monitoring of aquatic organisms and water quality;

Biological methods for the treatment of water quality;

Analyses on the interaction between aquatic organisms and aquatic ecosystem health;

Effects of water quality on aquatic animals in captive and natural environments at the ecological, physiological, and molecular levels.

We look forward to receiving your contributions.

The genus Vibrio is genetically and ecologically diverse, resulting in severe economic losses in aquacultural macroalgae and animals. Studies on vibrios will contribute to the conservation of aquatic aquaculture in Ría de Vigo (Spain), which is famous for its shellfish farming activity. However, limited research focused on the diversity and distribution of Vibrio spp. in Ría de Vigo has been reported. Here, a slight increase in the abundance of Vibrio spp. was recorded from inshore to the open sea by quantitative PCR (qPCR). Vibrios were more abundant in the free-living (FL) than in the particle-associated (PA) fraction, showing that FL might be their preferential lifestyle. Photobacterium piscicola, Vibrio japonicus and Vibrio harveyi, which are serious pathogens for fish and invertebrates in mariculture, were found to be the dominant species across all samples by high-throughput sequencing and analyses and were mainly affected by stochastic processes. More colony-forming units and species of vibrios were recorded at 16 °C (18 species) than at 28 °C (6 species), and five isolates (5.05% of the total isolates) showed low 16S rRNA gene similarity (<98.65%) to the known strains. The results indicate that culture conditions closer to the in situ temperature may help to isolate more Vibrio species. Our findings may contribute to local aquatic aquaculture research, providing background information and novel insights for management and pathogen prevention in aquaculture, and more studies should focus on Ría de Vigo to acquire novel or pathogenic microbes in the future.

Against the backdrop of hydropower development in the upper Yellow River, comprehending the spatiotemporal variation and ecological evaluation of macroinvertebrate functional feeding groups (FFGs) is paramount for the conservation and restoration of aquatic biological resources in watersheds. Detailed surveys of macroinvertebrates were conducted in the gorge and plain areas of the upper Yellow River in July 2022 and March, May, and October 2023, culminating in the identification of 65 taxonomic units (genus or species) spanning 4 phyla, 14 orders, and 35 families. Of these, 41 taxonomic units were discovered in the gorge areas and 57 in the plain areas. Among the FFGs of macroinvertebrates in the upper Yellow River, collector-gatherers were overwhelmingly dominant, followed by scrapers, collector-filterers, predators, and shredders. Concerning river section types, dominant species in the gorge areas included Gammarus sp., Limnodrilus hoffmeisteri, and Polypedilum sp. among collector-gatherers, while in the plain areas, dominant species included Ecdyonurus sp. among scrapers, Hydropsyche sp. among collector-filterers, and Gammarus sp., Limnodrilus hoffmeisteri, and Chironomus sp. among collector-gatherers. A Mantel test revealed that dissolved oxygen, conductivity, and orthophosphate were the primary environmental factors affecting the FFGs of macroinvertebrates in the upper Yellow River, with variations observed in their effects across different months. The evaluation results of the Hilsenhoff Biological Index and Shannon–Wiener Index indicate that the water quality of the upper Yellow River is at a moderate level. An assessment of the upper Yellow River ecosystem using FFG parameters demonstrated that macroinvertebrate biomass progressively increased from upstream (gorge areas) to downstream (plain areas) spatially, accompanied by increasing habitat stability, with cascade hydropower development identified as a key factor impacting habitat stability. These findings provide pertinent data and a theoretical foundation for the protection of aquatic biological resources and watershed management in the upper Yellow River. Full article
