The report also documents that, whilst diseases caused by bacteria are under good control, Norway has seen a recent rise in viral diseases.

"There was a sharp increase of pancreas disease (PD) in 2014. It was the highest number of registered cases of PD so far," said Atle Lillehaug, researcher and project manager at the National Veterinary Institute.

There was also a moderate increase in infectious salmon anemia (ISA) cases and Ameobic Gill Disease (AGD) has continued to spread.

This year, the US's Lake Erie is expected to suffer some of the worst harmful algal bloom's (HAB) in years.

Scientists from the National Oceanic and Atmospheric Administration (NOAA) have predicted that the 2015 western Lake Erie harmful algal bloom season could become the second most severe behind the record-setting 2011 bloom.

The bloom, which will peak in September, is expected to measure 8.7 on the severity index with a range from 8.1 to potentially as high as 9.5.
