‘Blue foods’ from aquaculture provide an invaluable source of nutrition but can be resource‐intensive and relatively unsustainable to produce. Naked clam aquaculture, the farming of wood‐boring bivalves of the family Teredinidae, offers a means to rapidly and sustainably convert wood into a low‐environmental impact and nutrient‐dense protein. Naked clam aquaculture is unique due to the ease with which

Fundamental metabolic functions depend upon the endoplasmic reticulum (ER), as this organelle plays a central role in maintaining cellular homeostasis. Different physiological and pathological conditions can result in the accumulation of misfolded/unfolded proteins, which this accumulation causes ER stress. These pathological conditions can lead to disease and are concerning for species used for aquaculture

The presence of organic pollutants in aquatic environments requires effective solutions to reduce their concentration. In this context, the development of environmental remediation technologies using nanomaterials has emerged as a promising alternative. However, prior to their application, it is necessary to evaluate the toxicity of these materials along their lifecycle. The aim of this study was to

MCPA-Na (2-methyl-4-chlorophenoxyacetic acid) is a selective herbicide widely used in agricultural cultivation. Despite monitoring indicating risks to aquatic life, the specific organ effects and pathogen susceptibility are unclear. Therefore, we constructed a “compound-core target-signaling pathway” network using network toxicology methods, and the results showed that MCPA-Na interacted with multiple

Anionic Polyacrylamide (APAM) is widely used in oil extraction processes, serving as an oil-repellent polymer and constituting a critical component of water-based drilling fluids. The environmental and ecological effects of APAM on fishery resources have attracted significant attention, yet its toxic mechanism in marine fish at early developmental stages remains poorly understood. The potential effects

Microplastics (MPs) are newly emerged pollutants found in water and soil, while microcystin-leucine arginine (MC-LR) is often detected in drinking water and water products, both posing serious threats to aquatic environment and food safety. MPs can serve as carriers of MC-LR. These pollutants are often found together, rather than separately. This study focused on assessing the neurotoxicity of co-exposure

The gut-liver axis is vital for organism health. Nanoplastics (NPs) and bisphenol A (BPA) can harm zebrafish intestines and livers, yet their combined impact on the gut-liver axis and transgenerational effects are unknown.

The widespread application of pesticides makes it important to understand the impacts of these chemicals on wildlife. Chlorpyrifos, an organophosphate insecticide that is still used en masse over large parts of the globe, can affect the development and behavior of non-target organisms and may thereby alter predator-prey interactions. To investigate whether environmentally relevant concentrations of

Tebuconazole (TBZ) is a triazole fungicide broadly used to control fungal diseases in agricultural crops, fruit-bearing plants and forestry plantations. However, its increasing use and release into aquatic environments has raised concerns about its hazardous effects on the health of fish. Thus, the aim of the present study was to review the scientific literature on the ecotoxicological effects of TBZ

The widespread use of antibiotics has significantly contributed to the spread of antibiotic resistance genes (ARGs), which have become a major challenge to global ecological and public health. Antibiotic resistance not only proliferates in clinical settings but also persists in aquatic systems, where its residues and cross-domain spread pose a dual threat to both ecosystems and human health. ARGs spread

Conventional plastics have become a major environmental concern due to their persistence and accumulation in marine ecosystems. Recently, the development of bio-based polymers, such as polylactic acid (PLA), has gained particular attention as an alternative to limit plastic pollution, as these materials can be degraded under certain conditions. This study investigated the ecotoxicity of polylactic

This study evaluated the individual and combined impacts of temperature, pyrene, and cadmium on the coastal diatom Thalassiosira weissflogii under conditions representative of the Gulf of Guinea. In the individual stressor experiments, time, rather than temperature or individual pollutants, was the primary factor influencing growth parameters. Specifically, temperature modulated diatom growth with

The growing use of data‐poor fisheries models provides unprecedented access to compelling stock metrics and management scenarios for coral‐reef fisheries. Yet, it remains unclear how well the assumptions surrounding data‐poor models derived from extensive cold‐water fisheries fit the life histories and ecology of tropical coral‐reef fishes. The present study compared the outcomes from length‐based

Microplastics (MP) are a diverse class of contaminants for which it is challenging to assess their effects on freshwater biota. As polyamide (PA) and polyvinyl chloride (PVC) are two of the most abundant microplastic materials in natural environments, the present study investigated whether their chronic presence, particle size (< 100 μm and > 100 μm) and their mixture influenced gene transcription

Fish predation poses a significant challenge to bivalve aquaculture throughout the global range of production. However, the issue remains poorly understood, preventing the advance of effective interventions. Fish predation, especially on mussels in longline culture, can be severe and, in some instances, lead to crop losses of up to 100%, which has resulted in the closure of farming operations in several

In aquaculture, the quantitative analysis of fish school behavior refers to the systematic application of mathematical and statistical tools for the precise measurement and description of fish school behavior characteristics through metrics, statistics, and modeling. Compared to studies on individual behavior, the analysis of fish school behavior is crucial for managing fish health and enhancing aquaculture

Seaweed aquaculture is rapidly growing globally and offers environmental benefits such as reducing eutrophication and increasing biodiversity.

Over the past decade, several innovative research projects have explored and developed techniques tailored toward sustainable seaweed aquaculture

There is increased evidence of the co-occurrence of microplastics (MPs) with other co-pollutants in surface water globally, leading to ecological and environmental concerns. The risks and toxicity of co-occurring pollutants largely depend on the mechanisms controlling the activation of their various sources, their fate and transport in different environmental media. Due to their size-specific surface

Megalocytivirus, a large double‐stranded DNA virus belonging to the Iridoviridae family, has infected over 100 species of fish, leading to significant economic losses in the aquaculture, food, and ornamental fish industries. These viruses exhibit icosahedral symmetry and have diameters ranging from 120 to 200 nm. Two distinct viral species of genus Megalocytivirus have been identified: Megalocytivirus

The early detectable tail coiling behavior of zebrafish (Danio rerio) embryos is receiving increasing attention in the context of (developmental) neurotoxicity testing and may be used as a rapid screening tool for compounds with unknown or suspected neurotoxic potential. The observation of this behavior over a longer period of time already offered advantages such as the possibility of detecting effects

Ibuprofen (IBU), a prevalent non-steroidal anti-inflammatory drug (NSAID), is extensively utilized in medical practices. Especially since the popularity of COVID-19, its use has become more widespread, coupled with its low degradation rate and high environmental residues. Thus, more focus is warranted on the possible detrimental impacts on non-target organisms, as well as the underlying mechanisms

Buprofezin (BPFN), a pesticide used to control crop pests and diseases, causes potential harm to aquatic animals and the environment by leaching into aquatic ecosystems. However, there are limited studies on the toxicity of BPFN to aquatic organisms. Using zebrafish embryos, we integrated flow cytometry, qRT-PCR, RNA-seq and other techniques to assess BPFN's developmental toxicity. Additionally, IBRv2

Mixed‐species fish shoals are common, and form for a variety of reasons. We suggest that short term mixed‐species shoals, that persist for minutes or hours, might form because lone individuals (or small groups) of one species might benefit from joining larger groups of heterospecifics to reduce predation risk. We carried out a literature survey, which revealed that mixed‐species groups seldom contain

This review examines the progression of fish bioacoustics and ecoacoustics, with a focus on the growing application of Passive Acoustic Monitoring (PAM) as a non‐invasive tool for assessing fish biodiversity.

Boscalid (BO), one of the frequently detected fungicides of succinate dehydrogenase inhibitor in water environments, has unknown effects on the respiratory function and gut health of aquatic organisms. Therefore, zebrafish were exposed to BO solutions (0.01–1.0 mg/L) for 21 days to assess its effects on zebrafish respiration and intestinal microbiota in this study. The results showed that exposure

Targeted management interventions can influence marine resource user behaviour, yet some remain ineffective. Behavioural economics may offer valuable insights on this topic by identifying which interventions can effectively change human behaviour and how they can be applied. This systematic review (N = 140) synthesises evidence from behavioural economics studies conducted in a fisheries context. The

Demographic models are vital tools in fisheries management, particularly for data‐limited species such as sharks and rays. However, a significant gap exists in the statistical quantification of productivity metrics related to elasmobranchs. This study addresses this gap by conducting a meta‐analysis of population models for sharks and rays, framed within a scientometric context. We reviewed 91 publications

As intensive aquaculture continues to develop, substantial investments have been made in equipment to sustain high‐density farming. However, this has resulted in elevated noise levels within these aquaculture environments, particularly below 2000 Hz, matching the hearing range of most cultured fish species. Fish under noise conditions may experience hearing loss and physiological stress, which can

Micro- and nanoplastic particles (MNPs) are pollutants of global concern due to their persistence, ubiquity, and associated risks. Laboratory studies, however, have predominantly focused on pristine MNPs, which do not adequately reflect the characteristics of environmental plastic debris. To address this gap, this study investigated the cellular and tissue-level responses of mussels (Mytilus edulis)

Over the past few decades, the accumulation of micro- and nanoplastics (MNPs) have identified as enduring contaminants, posing significant risks to aquatic organisms. However, the interplay of MNPs and environmental stressors (e.g. nutrient etc.) is not well understood.

The widespread use of the organophosphorus flame retardant tris(2-butoxyethyl) phosphate (TBOEP) and its presence in aquatic environments pose a hazard to wildlife. This study investigates the chronic ecotoxicity of TBOEP at environmentally relevant concentrations (6 ± 0.7 µg L−1) in the tropical water flea Ceriodaphnia cornuta over seven generations. Delayed toxicity emerged from the second generation

Agrochemical organosilicone spray adjuvants, widely applied in agroecosystems, are suspected to pose environmental risks based on recent studies. In response to these concerns, we have purified the active components of these adjuvants, specifically a series of oligomers of hydroxy(polyethyleneoxy) propyl-heptamethyl trisiloxane (TSS-H), including ethylene oxide (EO) units ranging from 4 to 12. For

Oxygenated polycyclic aromatic hydrocarbons (OPAHs) are a class of anthropogenic, persistent, and highly toxic PAH contaminants associated with developmental toxicity, 9-fluorenone (9-FLO) is a typical member of the OPAH family. Due to its ketone group, it has higher polarity, which results in increased solubility in water and greater potential for transport via atmospheric particles or water bodies

A comparative ecotoxicological profile was conducted on plastic materials with the same use made of conventional polymers versus alternative, potentially biodegradable polymers, frequently marketed as “bio” with claims of lower ecological impact. The sensitive in vivo sea-urchin embryo test (SET) was used for the ecotoxicological characterization, and non-target chemical analyses using GC–MS for the

Even though extensive research exists on the negative impact of nanoplastics on fish, their effect on the microbiota and intestinal health of freshwater fish remains unclear. This study investigated the impact of polystyrene nanoplastics (PS-NPs) on the microbiota, oxidative stress, and intestinal morphology of the Acrossocheilus yunnanensis (A. yunnanensis) freshwater fish species. The findings demonstrated

Aquatic organisms face increased complexity and severity when exposed to the combined stressors of climate change and micro- and nanoplastics (MNPs), as opposed to facing these stressors individually. This study examined the effects and underlying mechanisms of elevated pCO2, which leads to freshwater acidification, as well as amino-modified polystyrene MNPs (PS-NH2 MNPs) of varying sizes (5 μm, 300

Our understanding of the ecotoxicology for tropical marine species is limited. We investigated the impacts of copper (0.1–6 µg/L) and zinc (2.5–45 µg/L) on development of the crown-of-thorns sea star (COTS) (Acanthaster sp.) with respect to lethal concentration (LC) and effective concentration (EC) for inhibition of larval swimming and in context with concentrations reported for the Great Barrier Reef
