Where are the wild things going?

The Fish Site –

As we approach midsummer and the sea temperature rises, a number of subtle changes are taking place in Scotland’s west coast waters: more plankton in the water column, more seaweed growth and the return of warm-weather species.

Whilst none of this might sound significant, it does affect things on site. The nets need to be cleaned more regularly, we must be vigilant for jellyfish, as these can have negative impacts on gill health, and we have fitted an aeration system across the fish farm as a precautionary measure against algal blooms.

However, watching these natural environmental changes unfold on a daily basis is a privilege that many do not have. This small, seasonal increase in temperature has the power to transform the environment around us. Witnessing it first-hand has reinforced my impression of how diverse and productive, yet sensitive, our marine environment is.

A UN report was recently released, warning us of unprecedented levels of species loss globally. A million plant and animal species are now threatened with extinction – largely due to us, the human race. In Scotland, we are all too aware of the declining wild Atlantic salmon population, which has also received its fair share of media coverage lately.
