In the present work, marine invertebrate Mytilus galloprovincialis was used as model organism to evaluate toxic effects of neonicotinoid Calypso 480 SC (CAL) following 20 days exposure sub-lethal concentrations 7.77 mg L-1 (0.1% 96 h-LC50) and 77.70 (1% h-LC50), a recovery period 10 in uncontaminated seawater. Results revealed that both CAL increased significantly mortality rate cells haemolymph digestive gland, while gland were no longer able regulate cell volume. Exposure reduced parameters (Cl-, Na+), affected enzymatic activities superoxide dismutase catalase gill, caused also histopathological alterations gills. Main histological damages detected mussels lipofuscin accumulation, focal points necrosis, mucous overproduction infiltrative inflammations. Interestingly, persisted after CAL-free water, especially for haemocyte (K+, Na+, Ca2+, lactate dehydrogenase, glucose). A slight conditions detected. These findings suggested sub-chronic insecticide significant tissue M. galloprovincialis. Considering ecologically commercially important role coastal waters, potential risk posed by neonicotinoids this essential aquatic resource can be highlighted.

Fish gills are in direct contact with the surrounding pollutants, and thus, potentially more vulnerable to microplastics (MPs) heavy metals. The present study aimed evaluate long-term exposure effects of MPs copper (Cu) adult zebrafish (Danio rerio). To this end, were exposed (2 mg/L), Cu (Cu25, 25 μg/L) their mixture (Cu25 + MPs) for 30 days, then oxidative stress, detoxification, antioxidant, metabolic neurotoxicity enzymes/genes, as well serotonergic system apoptosis genes, evaluated gills. In group, ROS levels increased, while CAT GPx activities inhibited, indicating induction stress This was followed by an increase LPO potential damage tryptophan hydroxylase 1a (tph1a) caspase-3 (casp3) genes significantly upregulated Cu25 a dysregulation serotonin synthesis pathways, respectively. Overall, contributes improving knowledge about response aquatic organisms ecological risk that these particles represent ecosystems.

Global meta‐analysis reveals diverse effects of microplastics on freshwater and marine fishes

Abstract Microplastic debris is a globally ubiquitous pollutant with diverse consequences for fishes, ranging from severe negative impacts to neutral, or even, positive effects. In the present study, we conducted systematic review and meta‐analysis of experimental observational studies test microplastic exposure on freshwater, estuarine marine fishes across taxonomies, geographies, ecosystem contexts. We report evidence detrimental, albeit variable, microplastics, including reduced consumption, altered feeding behavior, obstructed digestion assimilation, decreased growth, compromised immunity. By contrast, microplastics appeared invoke neutral responses in several other ecological physiological processes, such as body condition, fecundity, hatching success survival. The results this study also point mismatch between types, shapes, sizes investigated settings versus those found fish wild, well striking difference 728 species contamination wild only 22 evaluated effects laboratory. reiterates necessity more consistent methodological approaches analyzing reporting exposure, greater taxonomic breadth use environmentally relevant polymers future studies. Furthermore, model simulations that explore individual‐ population‐level implications realistic scenarios are needed. Overall, current weight supports continued management policy actions reduce production, use, release into world's waters.

Captivating Colors, Crucial Roles: Astaxanthin’s Antioxidant Impact on Fish Oxidative Stress and Reproductive Performance

Animals, Год журнала: 2023, Номер 13(21), С. 3357 - 3357

Опубликована: Окт. 29, 2023

Fish, constantly exposed to environmental stressors due their aquatic habitat and high metabolic rates, are susceptible oxidative stress. This review examines the interplay between stress fish reproduction, emphasizing potent antioxidant properties of astaxanthin. Our primary objective is highlight astaxanthin's role in mitigating during critical reproductive stages, leading improved gamete quality, ovary development, hormone levels. We also explore its practical applications aquaculture, including enhanced pigmentation overall health. conducted a comprehensive literature review, analyzing studies on impact reproduction. Astaxanthin, carotenoid pigment, effectively combats reactive oxygen species, inhibiting lipid peroxidation maintaining membrane integrity. It significantly enhances success improves health aquaculture settings. reveals multifaceted benefits offering economic advantages aquaculture. Future research should delve into species-specific responses, optimal dosages, long-term effects astaxanthin supplementation inform sustainable strategies.
