Summary: This study describes the current situation of chlorpyrifos (CPF) in Mexico, revealing its high sales and usage rate. The analysis of soil, water, and fish samples indicates the presence of CPF, posing a threat to wildlife and human health. Hence, it is recommended to ban the use of CPF in Mexico to prevent serious neurocognitive health problems.

Summary: This study confirmed the need for additional phospholipids in Atlantic Salmon fry diet for optimal performance. Marine-based phospholipids significantly improved growth and survival rates of salmon juveniles, while soy lecithin showed slightly weaker performance in growth compared to marine-based phospholipids.

Summary: Atlantic salmon fed a carbohydrate-rich diet showed suboptimal growth performance and metabolic disturbances. The study aimed to investigate the effects of graded levels of digestible carbohydrates on the distal intestine digesta microbiota in Atlantic salmon. The results demonstrated that feeding a high digestible carbohydrate diet led to negative effects on growth parameters and liver health, including increased lipid vacuolization and expression of fatty acid synthase. The composition of distal intestine digesta microbiota also changed with the carbohydrate-rich diet. Furthermore, certain lactic acid bacteria were found to be negatively correlated with hepatic steatosis and other liver health indicators. The potential use of lactic acid bacteria as probiotics to improve liver health in carnivorous fish fed a fatty liver-induced diet deserves further investigation.

Summary: The study emphasizes the importance of biodegradation in degrading CPF, pointing out the limitations of traditional degradation methods, and the need to simultaneously degrade both CPF and TCP. In addition, experiments confirm the potential of bioremediation in removing pesticide residues in wastewater treatment.

Summary: Biologically active compounds used in agriculture can easily spill into aquatic environments, leading to the accumulation of insecticides and other chemicals in aquatic organisms. These insecticides may induce immunotoxic responses, altering the immune system of fish and even causing death in severe cases.

Summary: This study systematically investigated the hydroxylamine (HA) promoted activation of persulfate (PS) by chalcopyrite (CuFeS2) for the removal of chlorpyrifos (CPF) and imidacloprid (IMP) in water. The results showed that HA greatly accelerated the regeneration of Cu2+ and Fe3+ in solutions for PS decomposition. CuFeS2/PS/HA process achieved a high removal rate of CPF and synchronously removed IMP under certain conditions. The study proposes possible pathways for CPF degradation and enhanced mechanism for both CPF and IMP removal by CuFeS2/PS/HA process.

Summary: This review focuses on the water holding properties of Atlantic salmon, evaluating the methods used to measure them and how pre- and postmortem factors, processing, and preservation methods influence these properties and their correlations to other quality parameters. Various methods are available to measure water holding capacity (WHC), with the centrifugation method being the most prevalent but other non-invasive and cost-effective approaches increasingly preferred. The diversity of methods makes direct comparison of results from previous research relative unless the same method is used with the same conditions.

Summary: The study assessed the spatial and temporal variation of organophosphate pesticides chlorpyrifos and dimethoate in two agricultural drainage ditches in northern Sinaloa state, Mexico. It was found that concentrations of chlorpyrifos in water and sediment exceeded quality criteria, posing a hazard to the environment and human health as the ditches discharge into the Gulf of California.

Summary: Plants recruit specific microorganisms from the soil to cope with biotic or abiotic stress. Foliar spraying of pesticides leads to changes in rhizosphere microbiota, and rice plants respond to the stress by releasing certain substances in root exudates, resulting in a shift in bacterial community composition and enrichment of Sphingomonas sp. Furthermore, these bacteria can consume linolenic acid and alleviate pesticide stress.

Summary: The abuse of chlorpyrifos has led to environmental pollution and toxicological effects on non-target organisms. It enters the ecosystem through the food chain and directly affects non-target organisms in water environments. The study demonstrates the toxic effects of chlorpyrifos on rats and the mitigating effects of chitosan oligosaccharide. Chitosan oligosaccharide shows significant biological effects in mitigating the toxic damage in rats induced by chlorpyrifos.

Summary: This review discusses the chemical quality markers of Atlantic salmon, including lipids and pigmentation. These markers are influenced by diet and other important factors. Various analysis methods are used to monitor these quality parameters, with some considered industry standard. However, recent advances in spectroscopic techniques offer faster and non-invasive alternatives with great potential in fisheries science.

Summary: An unbalanced gut microbiota in fish may promote bacterial infections. However, the interactions between different bacterial groups and their effects on fish health are not well understood. This study found that pathogenic species were present in the digestive tract and gut mucosa of healthy salmon, and the dysbiosis in sick salmon may be associated with cooperative interactions between different taxonomic families of bacteria, leading to clinical symptoms.

Summary: The use of plant-based feeds in fish farming has introduced undesirable substances such as pesticides. Research indicates that commercially produced Atlantic salmon feed may contain unsafe levels of the pesticide pirimiphos-methyl (PM-m), leading to adverse effects on fish health. Fish fed with PM-m spiked feeds showed growth reduction, oxidative stress, liver damage, and disturbances in lipid metabolism. Safe limits for dietary PM-m were determined through dose-response analysis, setting the daily safe dose for fish consumption.

PFOS was the most abundant compound, and PFAS levels and patterns varied between fish tissues. The dietary intake of certain PFASs in fish from Jeddah exceeded safety thresholds, posing a potential health risk to humans.

Summary: This study investigated high concentrations of mercury in deep-water fish species in Norwegian fjords, focusing on tusk sampled from Sognefjorden in Western Norway. Analysis of liver tissue revealed a significant correlation between fish weight and accumulation of methylmercury (MeHg), leading to potential sublethal effects. Transcriptome analysis identified hundreds of differentially expressed genes linked to pathways involved in protein folding, adipogenesis, and lipid metabolism, suggesting negative impacts of mercury bioaccumulation on tusk in Sognefjorden.

Summary: This study investigates the impacts of tailings from a calcium carbonate processing plant on early live stages of haddock and Atlantic cod. Results show that mineral particles adhere to fish eggs, affecting egg buoyancy, survival, and development. Tailing exposure induced early hatching, reduced survival, and caused malformations in larvae, particularly in cod.

Summary: This study investigated the effects of mine tailing exposure on marine copepods and found that exposure led to slower growth and reduced lipid accumulation. The presence of metals and processing chemicals did not influence these responses, suggesting that uptake of mineral particles was responsible for the observed effects. The applied dynamic energy budget (DEB) model confirmed that ingestion of tailing particles while feeding can result in less energy being available for growth and development.

Summary: The study found that 6PPD quinone is toxic to zebrafish larvae, but no significant mortality was observed at the tested concentrations, resulting in a dose-dependent reduction in swimming performance. Exposure to environmentally relevant concentrations (1 µg/L) of 6PPD and 6PPD quinone did not affect the behavior of zebrafish embryos, while exposure to higher but sublethal concentrations (10 and 25 µg/L) can impact behavioral endpoints.

The GCF phenotype of salmon is similar to wild type (WT) counterparts in terms of growth and welfare, with the advantage of never maturing.

This study found that replacing conventional canola oil with DHA canola oil did not affect the growth, survival, or lipid digestion of the salmon. The fatty acid composition of the fish tissues was influenced by the different diets, with higher levels of DHA resulting in improved fillet quality.
