ONTROLLING THE WATER
-
FLOW
For correct operation the amount of water must be adjusted to the size of the fish. Generally
speaking, better separation of the fish will be achieved if not too much water is used. On the other
hand sufficient water must be used to flush the fish smoothly down the channel. The following
table can be used as a rough guideline. The figures are for salmon, other fish species (different
shape) may require slightly different amounts of water.
The figures shows how correct water flow can be achieved by using a stop watch and a water
bucket (12 – 14 litres). The time is measured while the water flows from the channel and fills the
bucket.
Fish size

LOPE OF THE CHANNEL
Generally, the slope of
the V-channel should be
about 0° - 5° for stable
operation. For higher
capacity
(and lower
accuracy) the slope can
be increased to 10° - 15°.
