“…In contrast, for cultured or farmed species, the researches mainly focus on marine shellfish and bivalves species but a very few freshwater species (Cole et al 2014;Wilcox et al 2015;Vandermeersch et al 2015;Koelmans 2015;Ziajahromi et al 2016;Lusher et al 2017;Lavers & Bond 2017;Carbery et al 2018;Ma et al 2019;Granek et al 2020). For example, study on the MPs from sea cucumber Apostichopus japonicas in the eight farms in the Bohai Sea and the Yellow Sea in China showed that MPs widely existed in sea cucumber farms (Mohsen et al 2019). In addition, researchers also tend to compare the MPs in the wild capture with the farmed aquatic animals.…”

According to the statistics, 8.3 billion metric tonnes of plastics have been produced since 1950s, which is far more than other synthetic materials and the annual production which are about 500 million tonnes per year at present. The production of plastics makes microplastics pollution extremely widespread distribution, which will have a lasting impact on the global environment, especially on the aquaculture systems. And the distribution of the microplastics is extremely imbalanced around the global waters. In the present review, we have summarized the development of aquaculture in the World and China based on the existing data sources. And the total aquaculture production of the World will over 90 million tonnes, which will exceed the capture production in 2020. Aquaculture products will become one of the most important sources of high-quality protein. However, we found that many kinds of microplastics are detected and enriched in both farmed and captured species. Both endogenous and exogenous factors like the use of fishing plastic products, factory farming facility and equipment, natural and synthetic feed, animal health products, aquaculture fortifier and aquatic food additives make accumulation of microplastics easier. In addition, the safety of aquaculture products is closely related to human health because the residues of microplastics in fish leading to various potential hazards. In summary, this paper reviewed the relationship between microplastics and aquaculture, aimed at calling for the rational and restricted use of plastic products in the aquaculture ecosystems.

“…Consequentially, PVC and PET, which are materials for plastic sewers, tubes and beverage bottles (Oberbeckmann et al 2016), are often found in freshwater sediments (Ehlers et al 2019;Jiang et al 2019). Once in the sediment, MPs are encountered by benthic organisms and are often consumed (Hurley et al 2017;Mohsen et al 2019). Therefore, to date, most microplastic studies have investigated the oral uptake of microplastics by (epi)benthic animals (Redondo-Hasselerharm et al 2018;Courtene-Jones et al 2019;Windsor et al 2019).…”

Caddisfly larvae occur in streams and rivers, and many caddisfly species build protective cases using material from their habitat such as sand grains. At the same time, microplastics (MPs) are regularly deposited in aquatic sediments and are incorporated into caddisfly (Lepidostoma basale) cases in the field. However, it is unknown what the effects of MP incorporation into cases might be on the health of the caddisfly larvae. Hence, we offered two commonly used MPs (polyvinyl chloride (PVC) and polyethylene terephthalate (PET)) to L. basale larvae during a laboratory experiment. Both plastic types have a high density and co-occur with L. basale larvae in benthic habitats. In our experiment, L. basale actively used sand, PET and PVC MPs for building tube-like portable or emergency cases. The latter is a temporary shelter under which the larva can hide for immediate protection. Furthermore, case stability decreased with increasing PVC and PET particle content in the cases, suggesting that MPs may threaten caddisflies by destabilising cases. When case stability is reduced, the protective function of the cases is limited and the larvae may be more prone to predation. Additionally, larvae may be washed away by the current as plastic is lighter than sand. Both effects could limit the caddisfly's survival, which could have far-reaching consequences as caddisfly larvae are important primary consumers in aquatic ecosystems.

Microplastics (< 5 mm) are widespread within the marine environment, posing a major threat to marine biota. The aim of the present study was to investigate microplastic contamination in three widespread and highly commercial fish from the coast of Lima, Peru. Peruvian silverside (Odontesthes regia), Peruvian morwong (Cheilodactylus variegatus), and Peruvian grunt (Anisotremus scapularis) specimens were caught off the coast of Lima. Fish stomach and intestines were extracted and submerged in 10% (w/v) KOH, followed by 24 h incubation at 60 °C. The resulting supernatant solution was vacuum filtrated and filters were then observed under an optical microscope and stereomicroscope. Strict quality control and external contamination prevention measures were taken. Microplastic abundance, type and color were recorded. Quality control measures resulted in reduced external contamination. C. variegatus was the most contaminated fish (5.13 ± 0.81 MP/individual), similar to A. scapularis (5.00 ± 0.46 MP/individual), but significantly different to O. regia (0.43 ± 0.11 MP/individual). Fibers were the overall most abundant microplastic type, while blue the dominant color. Results indicated highly contaminated fish, compared to those from other parts of the SE Pacific. Microplastic ingestion by C. variegatus and A. scapularis may be subject to trophic transfer from their natural prey. Highly populated cities and poor solid waste management may contribute to worsen microplastic ingestion by native marine species. The need for further research and a marine microplastic monitoring program was discussed.
