Microplastics in sediments below shellfish farms
AI summary Read the abstract
Researchers compared microplastic abundance in sediments beneath shellfish farms near Sibenik Bridge, Croatia against a reference station, finding higher total counts of both fibers and fragments at the farm site. The study underscores the need for continuous monitoring of microplastics in marine sediments near aquaculture operations and implementation of measures to reduce environmental input.
U ovom su diplomskom radu predstavljeni rezultati istraživanja prisutnosti mikroplastike u sedimentima ispod uzgajališta školjkaša u blizini Šibenskog mosta. Analizirano je 12 uzoraka sedimenta uzorkovanih na dvije postaje (postaji ispod uzgajališta školjkaša i kontrolnoj postaji) te su prebrojena i zabilježena vlakana i fragmenti mikroplastike. Rezultati su pokazali veći ukupni broj vlakana i fragmenata mikroplastike u sedimentu ispod uzgajališta školjkaša, u odnosu na referentnu postaju. Prikazani rezultati ističu potrebu za kontinuiranim praćenjem mikroplastike u morskim sedimentima te primjenu mjera za smanjenje njenog unosa u okoliš, kako bi se očuvali morski resursi i smanjili rizici za ljudsko zdravlje.

Microplastics in bivalves and their habitat in relation to shellfish aquaculture proximity in coastal British Columbia, Canada
AI summary Read the abstract
Researchers compared microplastic concentrations in Manila clams and Pacific oysters grown at commercial shellfish aquaculture sites versus reference beaches in coastal British Columbia, finding that proximity to aquaculture operations influenced microplastic levels in both bivalves and surrounding sediments.

This Croatian thesis examined microplastic contamination in Mediterranean mussels and flat oysters from Sibenik Bay, Croatia. Researchers collected organisms from commercial aquaculture sites and analyzed microplastic abundance and types using standardized methods.
Abundance of microplastics at and near a shellfish aquaculture farm: An eastern oyster (Crassostrea virginica) transplant study
AI summary Read the abstract
Researchers studied microplastic abundance at a shellfish aquaculture farm in Connecticut by transplanting eastern oysters between the farm and a nearby recreational bed. They found that oysters from both locations contained similar levels of microplastics, suggesting that aquaculture operations may not significantly increase microplastic loads compared to surrounding waters. The study provides useful baseline data on microplastic exposure in commercially farmed shellfish.
Abundance and distribution of microplastics within surface sediments of a key shellfish growing region of Canada
AI summary Read the abstract
Microplastics were found across all sediment size classes at shellfish farming sites in British Columbia, Canada, with higher concentrations in finer sediment fractions. The results raise concerns for the safety of bivalves grown in this region and for the broader health of one of Canada's most productive shellfish aquaculture areas.
Aquaculture in the crossroad of microplastic contamination
AI summary Read the abstract
Researchers investigated microplastic contamination in three commercially important shellfish species -- oysters, clams, and mussels -- from aquaculture operations in different climate conditions. They found microplastics present in all species and at all sites, with polyester and polyethylene being the most common types. The study raises awareness that aquaculture practices and equipment may contribute to microplastic contamination in farmed seafood.
