Article Synopsis
- The study investigates how volcanic ash impacts the feeding organisms, specifically adult females of Crepipatella peruviana, in seawater with varying ash concentrations.
- Results showed that increased ash levels led to higher mortality rates and decreased feeding, respiration, tissue weight, and overall health of the organisms.
- Additionally, severe gill degradation was observed, affecting their ability to feed effectively, while some antioxidant responses were triggered in reaction to the ash presence.
Article Synopsis
- Azamethiphos is a pesticide used in the salmon industry to combat sea lice, but it may harm non-target species like oysters, especially as seawater temperatures rise.
- The study evaluated the combined effects of azamethiphos (at different concentrations) and temperatures on oxidative damage in oyster gonads and gills over 7 days.
- Findings showed that lipid peroxidation increased over time in both gonads and gills, with protein damage also significant in gills across treatments, while exposure time had a greater impact on cellular damage than temperature.
