Microplastics (MPs) have attracted global concern because of their harmful effects on marine biota; toxic properties can negatively impact aquatic ecosystems. Fish is an essential source protein for humans, playing a crucial role in daily food intake. Until recently, MPs were addressed primarily as environmental pollutants, but they are now increasingly recognized contaminants the supply.

There has been a surge of research in the aquaculture industry investigating probiotic, prebiotic, and synbiotic interventions on physiological mechanisms fish, specifically digestive enzymes, oxidative stress, antioxidant defense. In probiotics have shown to improve nutrient utilization growth performance by stimulating enzymes. Meanwhile, probiotics, prebiotics synbiotics also studied for their ability modulate stress defense highlighting multifaceted health benefits. This review identified current trends, gaps, future considerations this evolving field. Although promising findings made, significant gap exists understanding specific role prebiotics, modulating systems variety fish species. As study investigate into existing body literature, it becomes evident that while certain aspects these interactions elucidated, nuanced comprehensive still needs be discovered. The variations experimental design, species-specific responses, lack standardized methodologies contribute complexity Digestive physiology vary among different species, so should focus responses formulations. It will possible establish robust correlations between dietary observed effects through systematic design methodology approach. Accordingly, further is needed understand Identifying gaps adopting can help develop tailored strategies optimize performance.

Combined effects of heatwaves and micropollutants on freshwater ecosystems: Towards an integrated assessment of extreme events in multiple stressors research

Global Change Biology, Journal Year: 2021, Volume and Issue: 28(4), P. 1248 - 1267

Abstract Freshwater ecosystems are strongly influenced by weather extremes such as heatwaves (HWs), which predicted to increase in frequency and magnitude the future. In addition these climate extremes, freshwater realm is impacted exposure various classes of chemicals emitted anthropogenic activities. Currently, there limited knowledge on how combined HWs affects structure functioning ecosystems. Here, we review available literature describing single effects different levels biological organization, obtain a holistic view their potential interactive effects. We only found few studies (13 out 61 included this review) that investigated combination with chemical pollution. The reported varied largely not within trophic but also depending studied endpoints for populations or individuals. Hence, owing little number available, no consistent could be highlighted at any level organization. Moreover, an imbalance towards species population experiments, five using multitrophic approach. This results gap relevant community ecosystem endpoints, prevents exploration important indirect can compromise food web stability. impairs validity risk assessments our ability protect Finally, highlight urgency integrating extreme events into multiple stressors provide specific recommendations guide further experimental research regard.

In aquaculture, fish are stressed with several factors involved in impacting the growth rate and health status. Although Nile tilapia can resist brackish water conditions, hypoxia status may impair condition of fish. were exposed to salinity at 0, 10, 20‰ for four weeks then behavior was checked. The results showed meaningfully lowered rate, feed utilization, survival when kept weeks. Then subdivided into six groups (factorial design, 2 × 3) normoxia (DO, 6 mg/L) 1 conditions 24 h.

Are mitochondria the main contributor of reactive oxygen species in cells?

Journal of Experimental Biology, Journal Year: 2021, Volume and Issue: 224(5)

Published: March 1, 2021

ABSTRACT Physiologists often assume that mitochondria are the main producers of reactive oxygen species (ROS) in cells. Consequently, biomedicine, considered as important targets for therapeutic treatments, and evolutionary biology, they mediators life-history tradeoffs. Surprisingly, data supporting such an assumption lacking, at least partially due to technical difficulties accurately measuring level ROS produced by different subcellular compartments intact In this Commentary, we first review three potential reasons underlying misassumption mitochondrial dominance production cellular ROS. We then introduce some other major sites/enzymes responsible production. With use a recently developed cell-based assay, further discuss contribution total rate release cell lines primary cells species. these cells, varies between types but never source This indicates although one significant sources ROS, not necessarily contributor under normal conditions. Intriguingly, similar findings were also observed variety stressors, strategies pathological stages, which rates significantly enhanced. Finally, make recommendations designing future studies. hope paper will encourage investigators carefully consider non-mitochondrial their study systems or models.

Marine foods are highly perishable products due to their high content of polyunsaturated fatty acids, which can be readily oxidized form peroxides and secondary oxidation products, thus conferring such undesirable organoleptic characteristics generating harmful compounds that detrimental the health consumers. The use preservation methods minimize lipid is required in fishing aquaculture industries. Low temperature storage (chilling or freezing) one most commonly used for fish seafood, although it has been shown fraction partially but not completely inhibited at low temperatures. extent depends on species time, among other factors. This paper reviews effect quality fish, either alone combination with techniques. antioxidant additives, hydrostatic pressure, irradiation, ozonation, ultrasounds, pulsed electric fields, design novel packaging help preserve chilled frozen further research needed develop more efficient processes from an economic, nutritional, sensory, sustainable standpoint.
