Summary: This study investigated the effects of co-exposure of chlorpyrifos (CPF) and zinc oxide nanoparticles (ZnO NPs) on fish-derived cells. A range of concentrations of CPF (0.312-75 mg/L) and ZnO NPs (10-100 mg/L) were tested in single and binary exposures. Commonly used cellular endpoints were measured to assess cytotoxicity. The results showed that CPF and ZnO NPs had significant effects on multiple endpoints, and the toxic interaction between CPF and ZnO NPs was more pronounced than with bulk ZnO.

Summary: This study investigated the mechanisms of acute and subchronic toxicity of waterborne thallium to rainbow trout. The results showed no significant effects on ionoregulatory enzymes and oxidative stress endpoints. The data suggest that ionoregulatory perturbance is a more likely mechanism of thallium toxicity in rainbow trout, particularly at elevated environmental concentrations.

Summary: The study found that CuNPs are bioavailable to olfactory mucosal cells and have different effects on rainbow trout compared to Cu2+. RNA-seq analysis revealed distinct mechanisms of action between the two contaminants, with CuNPs affecting olfactory signal transduction, calcium homeostasis, and synaptic vesicular signaling in OSNs. CuNPs also impacted neuroregenerative pathways and suppressed inflammatory signaling, without inducing oxidative stress or apoptosis.

Summary: This research investigated the impact of heavy metals on the reproductive health of rainbow trout from two locations. The study found that fish from the more polluted site had higher levels of iron and zinc in their tissues. Additionally, these fish experienced more severe damage such as cellular damage, apoptosis, oxidative damage, and altered hormone levels, compared to fish from the less polluted site.

Summary: Industrial operations lead to high concentrations of suspended particles in surface waters, which need to be treated before being discharged into fish-bearing waters. Adding flocculants is a common practice to improve the sedimentation of these particles. However, even small amounts of uncomplexed cationic polymer coagulant/flocculant remaining in the treated water can be highly toxic to fish. This study found that the toxicity of the cationic polymer is due to its accumulation on the gill epithelia, leading to hypoxemia in fish. The toxicity can be reversed by adding a neutralizing polymer.

Summary: The study found that exposure to mixtures of chlorpyrifos (CPF) and polystyrene (PS) microplastics (MPs) had significant effects on histopathological and histomorphometric biomarkers in rainbow trout, particularly in the gills and gut. Exposure to CPF and PS-MPs individually or combined led to significant changes in histomorphometric biomarkers in fish tissues.

Summary: The study aimed to determine the integrated stress response in rainbow trout after acute hypoxia. The results showed that physiological responses were significantly affected by hypoxic stress and their interaction with time after the challenge. The study also revealed the importance of different elements and areas of the stress response, including systemic and mucosal responses, in maintaining homeostasis.

Summary: The study investigated the tissue-specific effects of clothianidin on Oncorhynchus mykiss, revealing changes in behavior, neurotoxicity, osmoregulation disruption, and severe histological lesions with increasing concentrations. Clothianidin altered normal behavior, caused neurotoxicity, and disturbed osmoregulation, with tissue-specific responses and increasing severity of histological lesions indicating the potential threat of environmentally relevant concentrations of clothianidin to early life stages of fish.

Summary: This study evaluated the effects of including black soldier fly prepupae in rainbow trout fingerling diets. The results showed that replacing 50% of fish meal with black soldier fly meal had no adverse effects on growth performance, liver characteristics, feed utilization, or fillet quality. Therefore, black soldier fly meal can safely be used in rainbow trout fingerling diets.

Summary: Conserving biodiversity at genetic and community levels is crucial for the provision of ecosystem services. However, the application of genomics in biodiversity conservation and ecosystem service management is currently limited, primarily focusing on flagship species. To bridge this gap, a framework is proposed to guide genomics applications in management, including population supplementation, assisted migration, delimitation of conservation areas, and solving conservation trade-offs. Effective implementation of genomics-informed management actions requires collaboration between scientists and ecosystem service managers along with standardized workflows and training for managers.

Summary: This study investigated the effects of direct black soldier fly (BSF) feeding on the growth, health, and filet quality of rainbow trout. It was found that feeding dried BSF led to a reduction in growth, decreased feed intake, and constipation in the fish. The amino acid content of BSF prepupae was higher than that of commercial diet, and some fatty acid contents were similar to or higher than commercial diet. Feeding dried BSF once a day resulted in improvements in certain fatty acid levels in the fish.

Summary: This study investigated the effect of different organic waste substrates on the nutritional content of black soldier fly prepupae (BSFP). It found that BSFP reared on fruit and vegetable waste had lower protein and lipid content, but higher carbohydrate content compared to those reared on chicken waste meal and a mixture of the two. Additionally, BSFP reared on the mixture had higher levels of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids. These findings suggest that the use of certain organic waste substrates can enhance the nutritional value of BSFP and their potential as a sustainable protein source in aquafeeds.

Summary: The aim of this study was to use the transcribed spacer (ITS) region between 16S rRNA and 23S rRNA as a potential useful molecular target to differentiate L. garvieae from L. petauri for accurate discrimination between these two species. Seven SNPs were identified that separate L. garvieae from L. petauri based on the ITS region sequence. The 16S-23S rRNA ITS region can be used as a diagnostic marker to quickly identify the pathogens in a lactococcosis outbreak.

Summary: In this study, a bacteriophage specific to Aeromonas hydrophila was isolated from domestic wastewater. The phage was found to be icosahedral with a diameter of 60 nm. Based on the analysis of its genome sequence, the phage belongs to the genus Lahexavirus and does not contain antimicrobial resistance or virulence genes. Overall, the Lahexavirus APT65 phage may have potential as a therapeutic agent to tackle antimicrobial resistance in aquaculture.

Summary: Lactococcosis is a globally prevalent infectious disease that has a significant economic and sanitary impact on the rainbow trout industry. This study reveals that both Lactococcus garvieae and Lactococcus petauri are implicated in the etiology of lactococcosis, and that L. petauri plays a significant role in the epidemiology of this disease. Additionally, some biochemical differences between the two species may serve as phenotypic markers for their presumptive recognition.
