hi @crokkon,

You're right, I got confused with the data from the contribution from @ghulammujtaba which I took as accumulated data instead of results created between Jan 2017 and Feb 2018.

I have updated the data, analysis and conclusions for the section of variations of the populations of each species using data from a post from @arcange Steemit Statistics – 2018.02.26

In this post "Inactive" and "Red Fish" levels are used, which I have converted into plankton to maintain consistency with the rest of the analysis.

Thank you
