Reach statistics:

Fish Populations

The fish populations tab provide summary statistics for fish density and classification for the selected reach.

This sections contains 4 sub-sections.  The first one gives indications on the number of fisheries sites contained in the reach.  It also gives an indication of the representativeness of the statistics produced based on the number of sites within the reach.  Reaches with very few sites will provide statistics that are not reliable.  As the number of sites surveyed per reach increases, we gain confidence in the statistics produced.

In the case of this particular reach, we have 2 fisheries survey sites present which provides with a moderate level of representativeness.
