Taking samples with a fallfälla
on shallow soft bottoms
Collecting samples with a fallfälle
1. Decide the area to be surveyed and draw a map of it. Randomly
mark out 5-15 points on the map of where the samples will be taken.
2. Place the fallfällan on a sample site and net all the organisms
and place them in jars. After 10 sweeps with the net it can be assumed
that the fallfälle is empty.
3. Pour some of the water out of the jar so only a few centimetres
are left and top off with 3-4 cm 96-% alcohol.
4. Proceed to the next sampling area.
Examining your fallfälle samples
1. Pour your samples into a dish and sort them after what you think
they are for species and place them in different jars.
2. Be more accurate when determining the specie of the samples, count
the number and measure their size:
