Direct ingestion, trophic transfer, and physiological effects of microplastics in the early life stages of Centropristis striata, a commercially and recreationally valuable fishery species

Mixotrophic flagellate ingestion boosts microplastic accumulation in ascidians

“…It has been recently demonstrated that tintinnid ciliates, Favella spp, can actively ingest 10-20 µm MPs, consuming up to 10 MPs in an hour (Athey et al, 2020;Stienbarger et al, 2021). Similarly, we observed that cryptomonad flagellates actively ingest MPs.…”

“…The ability to ingest plastic microspheres by unicellular planktonic organisms, such as ciliates and flagellates, is well-known (Athey et al, 2020;Børsheim, 1984;Stienbarger et al, 2021;Nygaard et al, 1988).…”

“…Larvae of Centropristis striata were found to ingest a significantly higher number of MPs when fed with ciliates containing MPs than when they were directly exposed to MPs. In this case, sight could be a crucial factor for the results, as fish larvae are visual predators (Stienbarger et al, 2021).…”

Effects of microplastics on the feeding rates of larvae of a coastal fish: direct consumption, trophic transfer, and effects on growth and survival

“…Other studies have shown that ingestion of nanoplastics and microplastics by zooplankton is common (Cole et al 2013 ; Desforges et al 2015 ; Sun et al 2017 ; Cousin et al 2020 ), and that retention of microplastics is fairly low (Wang et al 2019 ), zooplankton as a group may be particularly susceptible to the negative effects of microplastic pollution. It is becoming increasingly clear that microplastics may be transferred up the food web (e.g., Setälä et al 2014 ; Cousin et al 2020 ; Hasegawa and Nakaoka 2021 ; Stienbarger et al 2021 ), more studies of the ecological effects of trophic transfer are needed. Our study found immediate effects on growth and a trend toward greater mortality when larval fish consume zooplankton that have ingested microplastics.…”

Microplastics and Their Impact on Reproduction—Can we Learn From the C. elegans Model?

“…They provide visual stimulus for ingestion by animal species ( Carpenter et al, 1972 ; Gramentz, 1988 ; David and Robert, 1994 ), or chemical cues for other foragers for preferential ingestion of MP-containing food ( Savoca et al, 2016 ; Savoca et al, 2017 ; Savoca et al, 2018 ; Procter et al, 2019 ). Accumulation of MPs and NPs have been widely recorded in various aquatic ( Lusher et al, 2013 ; Avio et al, 2015 ; Frydkjær et al, 2017 ; Gambardella et al, 2017 ; Critchell and Hoogenboom, 2018 ; Lo and Chan, 2018 ; Naidoo and Glassom, 2019 ; Masiá et al, 2021 ; Stienbarger et al, 2021 ; Liu et al, 2022a ) (reviewed in: ( Akdogan and Guven, 2019 ; Wang et al, 2019a ; Franzellitti et al, 2019 )) and terrestrial animals ( Huerta Lwanga et al, 2017 ; Maaß et al, 2017 ; Souza Machado et al, 2018 ; Panebianco et al, 2019 ; Lu et al, 2020 ; Mackenzie and Vladimirova, 2021 ). These studies have reported significant detrimental effects on animal development and health, including intestinal defects, decreased body size, decreased survival rate and reproduction, decreased motility, altered behavior, neurotoxicity, increased inflammation, oxidative stress, genotoxicity, altered fat and energy metabolism, and changes in the microbiome ( Tosetto et al, 2016a ; Lu et al, 2016 ; Lei et al, 2018a ; Jin et al, 2018 ; Fackelmann and Sommer, 2019 ; Poma et al, 2019 ; Qiao et al, 2019 ; Li et al, 2020a ; Araújo and Malafaia, 2020 ; Crump et al, 2020 ; Hirt and Body-Malapel, 2020 ; Prüst et al, 2020 ; Solleiro-Villavicencio et al, 2020 ; Yong et al, 2020 ; Li et al, 2021a ; Lear et al, 2021 ; Tagorti and Kaya, 2022 ).…”
