The growing trend of land-based aquaculture has heightened the significance comprehensively assessing air-water carbon dioxide (CO2) gas exchange in these inland waters, given their potential impact on neutral strategies. However, temporal variations partial pressure CO2 (pCO2) and flux clam fish ponds were barely investigated. We assessed water surface pCO2 one to five months intervals by deploying a lab-made buoy three fishponds located tropical subtropical climates. Measurements conducted over 24 h period each time, spanning from April 2021 June 2022, covering stocking, middle, harvesting stages culture cycle. Diurnal dominantly controlled biologically driven changes dissolved inorganic total alkalinity (~97 %), while temperature salinity effects minor (~3 %). Clam acted as sink atmospheric during stocking transitioned source middle stages. In contrast, throughout cycles strengthened when reaching Overall, weak for (−2.8 ± 17.3 mmol m−2 d−1), whereas (16.8 21.7 d−1). emission was stronger daytime coinciding with higher windspeeds compared nighttime fishponds. suggest incorporating high resolution measurements account diurnal culture-stage variations, enabling more accurate estimates ponds. Moreover, findings this study highlight importance feeding, aeration, biological activities (photosynthesis, remineralization, calcification) controlling such information can be used implementing better strategies achieve goals.

Abstract The diverse aquaculture sector makes important contributions toward achieving the Sustainable Development Goals (SDGs)/Agenda 2030, and can increasingly do so in future. Its role for food security, nutrition, livelihoods, economies, cultures is not clearly visible Agenda 21 declaration. This may partly reflect state of development policies compared with its terrestrial counterpart, agriculture, possibly also because production has historically originated from a few key hotspot regions/countries. review highlights need better integration global system dialogues. Unpacking aquaculture's functions generation values at multiple spatiotemporal scales enables understanding present future potential contribution to SDGs. Aquaculture unique that encompasses all aquatic ecosystems (freshwater, brackish/estuarine, marine) tightly interconnected through, example, feed resources other dependencies.

Abstract Aquaculture is a rapidly growing food production technology, but there are significant concerns related to its environmental impact and adverse social effects. We examine aquaculture outcomes in three pillars of sustainability framework by analyzing data collected using the Performance Indicators. Using this approach, comparable has been for 57 systems worldwide on 88 metrics that measure social, economic, or outcomes. first relationships among then analyze performance technology species. The results show are, average, mutually reinforced global systems.

Abstract Background Aquaculture plays an important role in global protein supplies and food security. The ban on antibiotics as feed additive proposes urgent need to develop alternatives. Gut microbiota roles the metabolism immunity of fish has potential give rise novel solutions for challenges confronted by culture. However, our understanding gut microbiome is still lacking. Results We identified 575,856 non-redundant genes metagenomic sequencing intestinal content samples grass carp. Taxonomic functional annotation gene catalogue revealed specificity carp compared with mammals. Co-occurrence analysis indicated exclusive relations between genera belonging Proteobacteria Fusobacteria/Firmicutes/Bacteroidetes , suggesting two independent ecological groups microbiota. association pattern expression modules liver was consistently opposite that Fusobacteria Firmicutes Bacteroidetes implying differential functionality / .

Microplastics (MPs) and antibiotic resistance genes (ARGs) pose significant challenges to the One Health framework due their intricate multifaceted ecological environmental impacts. However, understanding of how MP properties influence ARG prevalence in mariculture sediments remains limited. Herein, polystyrene (PS) polyvinyl chloride (PVC) MPs with different sizes (20-120 μm 0.5-2.0 mm) were selected evaluate impacts underlying mechanisms driving ARGs dissemination. The results showed that PS PVC increased relative abundance by 1.41-2.50-fold 2.01-2.84-fold, respectively, compared control, particularly high-risk genes. polymer type effect was identified as more influential than size sediment resistome evolution. shifted microbial community assembly from stochastic deterministic processes, thus enriching host pathogens. Furthermore, highly hydrophobic not only recruited bacteria colonization but also facilitated exchange within plastisphere. exogenous additives released (e.g., heavy metals, bisphenol A, tridecyl ester) particles synergistically promoted conjugative transfer inducing oxidative stress enhancing cell membrane permeability. These findings revealed characteristics spread marine benthic ecosystems, underscoring importance mitigating pollution maintain ecosystem health, prevent zoonotic diseases, balance global health.

Ectothermic vertebrates, e.g. fish, maintain their body temperature within a specific physiological range mainly through behavioural thermoregulation. Here, we characterise the presence of daily rhythms thermal preference in two phylogenetically distant and well-studied fish species: zebrafish (Danio rerio), an experimental model, Nile tilapia (Oreochromis niloticus), aquaculture species. We created non-continuous gradient using multichambered tanks according to natural environmental for each Each species was allowed freely choose preferred during 24h cycle over long-term period. Both displayed strikingly consistent temporal with higher temperatures being selected second half light phase lower at end dark phase, mean acrophases Zeitgeber Time (ZT) 5.37 h (zebrafish) ZT 12.5 (tilapia). Interestingly, when moved tank, only took longer time establish rhythms.
