ClearPlastics in scene: A review of the effect of plastics in aquatic crustaceans
Researchers synthesized 10 years of literature on plastic pollution effects across nearly 100 crustacean species, finding that ingestion, bioaccumulation, and trophic transfer are the most studied endpoints, and that crustaceans — spanning marine, freshwater, and estuarine habitats — represent both highly vulnerable organisms and valuable bioindicators for assessing plastic contamination in aquatic food webs.
Chemical cues for intraspecific chemical communication and interspecific interactions in aquatic environments: applications for fisheries and aquaculture
This review explores how aquatic organisms use chemical cues for communication, mating, feeding, and danger detection, and how this knowledge applies to aquaculture and fisheries. Researchers noted that global environmental changes, including ocean acidification and increasing plastic pollution, can disrupt these chemosensory behaviors. The study discusses practical applications such as using pheromones to improve breeding success and developing low-cost attractants for sustainable fishing.
Impacts of Contaminants on Crustaceans in the Field
This review examines how inorganic and organic contaminants in field conditions affect crustacean populations, finding that real-world pollutant mixtures including microplastics, heavy metals, and pesticides compromise crustacean physiology and contribute to population declines.
Pattern recognition receptors in Crustacea: immunological roles under environmental stress
This review examines how crustaceans like shrimp and crabs defend against infections using their innate immune system, and how environmental stressors including pollution weaken these defenses. While focused on crustacean health, the findings are relevant to humans because compromised shellfish immunity can affect the safety of farmed seafood that people consume.
Progress on the Effects of Microplastics on Aquatic Crustaceans: A Review
This review examined the effects of microplastics on aquatic crustaceans, finding that microplastics negatively affect life history, behavior, and physiological functions including oxidative stress, immune responses, and reproductive output across multiple species.
IMPACT OF HEAVY METAL CONTAMINATION ON PHYTOCHEMICAL PROFILES IN MARINE CRUSTACEANS: A COMPARATIVE STUDY OF Farfantepenaeus notialis AND Macrobrachium vollenhovenii
This review examined how heavy metal contamination affects phytochemical profiles — including antioxidants, pigments, and secondary metabolites — in marine crustaceans. Metal accumulation was found to disrupt normal biochemical composition with implications for seafood quality and consumer safety.
Invertebrates facing environmental contamination by endocrine disruptors: Novel evidences and recent insights
Researchers review the emerging evidence for endocrine disruption in invertebrates from anthropogenic chemicals, highlighting how invertebrate-specific hormonal pathways require dedicated research beyond vertebrate models, and noting that omics technologies now offer new tools to characterize disruption of these poorly understood systems across diverse invertebrate species.
The Effects of Combined Stress from pH and Microplastic-Derived Odours on the European Green Crab Carcinus maenas’s Olfactory Behaviour
Researchers tested how microplastic-derived odors and reduced seawater pH (simulating ocean acidification) combined to affect the olfactory behavior of European green crabs (Carcinus maenas). Using slow-release gel cues at pH values from 8.2 down to projected 2100 levels, they found that both stressors disrupted crab responses to sex pheromone and food cues, with combined exposure causing the most pronounced behavioral disruption.
Plastic waste interferes with chemical communication in aquatic ecosystems
Researchers found that plastic waste made of common polymers like HDPE and PET can absorb chemical signals that water fleas (Daphnia) use to detect predators, disrupting their ability to form protective physical defenses. This indirect effect of microplastics — interfering with chemical communication rather than causing direct toxicity — could have far-reaching consequences for aquatic food webs.
Ostracoda (Crustacea) as indicators of anthropogenic impacts – A review
This review examines how ostracods, tiny crustaceans found in lakes, rivers, and oceans, can serve as living indicators of water pollution from human activities including heavy metals, pesticides, and nutrient runoff. The authors note that ostracods have barely been studied in relation to microplastic contamination, presenting an opportunity for future research. Since these organisms are sensitive to water quality changes, they could become useful biological tools for monitoring microplastic pollution in aquatic environments.
Interference of Chemical Communication in Plankton: Impact of Nanoplastics
This review explains how nanoplastics — plastic fragments smaller than 1,000 nanometers — physically interfere with the chemical signals that aquatic plankton use to find mates, detect predators, and compete for food, effectively silencing the invisible communication networks that underpin freshwater food webs. Because plankton form the base of aquatic ecosystems, disrupting these chemical cues can cascade upward through food chains, reducing biodiversity and destabilizing ecosystems even at nanoplastic concentrations too low to cause obvious physical harm.
Microplastic leachates impair behavioural vigilance and predator avoidance in a temperate intertidal gastropod
Researchers found that leachates from microplastics impaired chemical vigilance and predator avoidance behavior in an intertidal gastropod, demonstrating that microplastic chemical contamination can compromise anti-predator responses in marine invertebrates even without direct particle ingestion.
Microplastics in decapod crustaceans: Accumulation, toxicity and impacts, a review
This review summarizes research on microplastic contamination in decapod crustaceans like shrimp, crabs, and lobsters, which are widely consumed as seafood. Studies have found microplastics accumulating in their gills, digestive organs, and gut, with experimental evidence showing oxidative stress, immune damage, and reproductive toxicity. The findings raise concerns about potential human exposure to microplastics through seafood consumption.
Microplastic pollution in wild populations of decapod crustaceans: A review
Researchers reviewed the occurrence and characteristics of microplastics found in wild populations of decapod crustaceans including crabs and shrimps. They found that fibrous microplastics smaller than 1 mm were the most commonly detected type, and that edible portions generally contained fewer microplastics than non-edible parts. The review highlights the importance of understanding microplastic contamination in commercially valuable crustaceans for both ecological and food safety assessments.
Ecological Exposure and Effects of Microplastics in Crabs Along the Pacific Coast
This study investigated how microplastic ingestion affects Pacific mole crabs — a common indicator species — finding that exposed crabs showed reduced predator avoidance ability, impaired reproductive output, and higher parasite loads. The results suggest that ecologically relevant levels of microplastic pollution can have cascading effects on both individual health and population dynamics in coastal crustaceans.
Plastic contamination in commercially valuable decapods caught near a major Australian urban centre
Researchers examined the digestive tracts of four commercially harvested decapod crustacean species near Perth, Western Australia for microplastics, and tested muscle and hepatopancreas tissue for plasticizer chemicals. Microplastics were found in all species' guts, and phthalate and bisphenol plasticizers were detected in edible tissues, raising food safety concerns for local seafood consumers.

This review assessed current methodological approaches for studying microplastic contamination in crustaceans, evaluating techniques for extraction, identification, and quantification while highlighting gaps in standardization that limit cross-study comparisons and risk assessment for these ecologically important invertebrates.
Parasites of invasive crustacea: risks and opportunities for control
This review examined parasites of invasive crustacean species and their potential as biological control agents, discussing both risks and opportunities for managing invasive populations. While focused on crustacean parasitology rather than microplastics, the work is relevant to understanding the health of commercially important shellfish species.
Potential use of gammarus (Pontogammarus maeoticus) and shrimp (Palaemon elegans) as biomonitors of microplastics pollution in coastal environments
Researchers investigated whether two crustacean species, gammarus and shrimp, could serve as biological indicators of microplastic pollution in coastal environments. They found microplastics in both organisms as well as in surrounding water and sediment, with fibers being the dominant type. The study suggests these common coastal species could be useful biomonitors for tracking microplastic contamination levels in marine ecosystems.
