“…Before the extraction procedures, several steps were carefully carried out to ensure quality assurance/quality control (QA/QC) and avoid possible airborne and cross-contamination, following the protocol described by Justino et al (2021). This QA/QC includes using 100% cotton lab coats, face masks, and disposable gloves in a cleaned and reserved room, with a limited flow of people during the whole process.…”

“…An alkaline digestion protocol using sodium hydroxide (NaOH) was used for extracting MPs from the digestive tract of fish (Justino et al, 2021). Digestive tract samples were rinsed with filtered distilled water to remove any particles adhering to the external tissue before being placed in a beaker and submerged in NaOH (1 mol L −1 ; PA 97%) solution (the proportion used was 1:100 (w/v), i.e.…”

“…Fish trophic level was taken from FishBase (see above) and ranged between 2.0 to 4.9. Trophic group categories were compiled from Quimbayo et al 123 and complemented with information from other literature [124][125][126][127][128][129][130][131][132][133][134][135][136][137][138][139][140][141][142][143] . The categories were invertivores, herbivores, macrocarnivores, omnivores, piscivores and planktivores.…”

Anthropogenic impacts on tropical and subtropical coastal environments are increasing at an alarming rate compromising ecosystem function, structure and services. Understanding the scale of marine population decline and diversity loss requires a long-term perspective that incorporates information from a range of sources. The Southern Atlantic Ocean, however, represents a major gap in our understanding of pre-industrial marine species composition. Here we contribute to fill this gap by performing an extensive review of the published data on Middle and Late Holocene marine fish composition along the southern coast of Brazil. This region preserves archaeological sites that are unique archives of past socio-ecological systems and of pre-European biological diversity. We assessed snapshots of species compositions and relative abundances spanning the last 5000 years, and modelled differences in species’ functional traits between archaeological and modern fisheries. We found evidence for both generalist and specialist fishing practices in pre-European times, with large body size and body mass caught regularly over hundreds of years. Comparison with modern catches revealed a significant decline in these functional traits, possibly associated with overfishing and the escalating human impacts in recent times.

“…The presence of MP was observed in several commercially important fish species for human consumption, such as Hoplosternum littorale, Cynoscion acoupa, and Dicentrarchus labrax (Mazurais et al, 2015;Lusher et al, 2016;Silva-Cavalcanti et al, 2017;Ferreira et al, 2018;Justino et al, 2021). Therefore, the intake of MP by species used for human consumption is a means through which humans are exposed to these particles and their chemical components (Bouwmeester et al, 2015;GESAMP, 2016;Jin et al, 2021;Nunes et al, 2021).…”

This literature review exploring the relationship between microplastics and ichthyoplankton was conducted in the main databases available online, considering the period from 2007 to 2021. Sixty articles were found reporting the presence of microplastics in estuarine environments (71.7%), and ingestion by ichthyoplankton in estuarine environments (16.6%) and under experimental conditions (11.7%). The most abundant microplastic found in natural environments was fiber (55%). Environments with densities between 17.5 and 4100 particles/m³ exhibited greater possibilities of ingestion of these particles by ichthyoplankton, the smaller the microplastic particle (63 μm-0.5 mm) the greater the probability (95%) of being ingested by ichthyoplankton (>2.56 mm). Danio rerio (zebrafish) was the species commonly used to assess the effects caused by the interaction between microplastics and ichthyoplankton under experimental conditions. The effects frequently reported were: increased heart rates (25%); growth inhibition (25%); interference in larvae’s swimming speed (53.4%); and inflammation in various organs (e.g., liver, intestine) (50%).
