Mercury is a known toxic metal, but studies on the effects of inorganic mercury ingestion in aquatic organisms are scarce. The present study aimed to investigate changes in feeding behaviour and biomarkers (lipid peroxidation, acetylcholinesterase, glutathione S-transferase and catalase activities) of yellowfin bream (Acanthopagrus australis) after ingestion of inorganic mercury (control: 0.2 mg kg-1, low: 0.7 mg kg-1, medium: 2.4 mg kg-1 and high: 6 mg kg-1) over 16 days. After 4 days, exposed fish attempted feeding more often, and showed a significantly lower eating success than controls. However, these differences became less notable with longer exposure periods. Most biochemical markers varied over time, regardless of mercury treatment. However, biomarker responses to mercury were also observed, mostly with increased exposure period and were dependant on the tissue analysed. This study showed that fish can recover from initial feeding behaviour effects of inorganic mercury, but showed delayed response in tissue biomarkers.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 December 2017.
All research outputs
#22,764,772
of 25,382,440 outputs
Outputs from Marine Environmental Research
#1,696
of 1,909 outputs
Outputs of similar age
#387,418
of 447,701 outputs
Outputs of similar age from Marine Environmental Research
#30
of 36 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,909 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.5. This one is in the 1st percentile – i.e., 1% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 447,701 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 36 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
