For
sites with strong currents over 1.5 knots a weighted circular ring
is suspended from the cage collar. The principal function of these
rings is to weight the bottom of the net and also retain the net shape
by applying force on the horizontal plane to the base panel of the
net. The weight of the ring is dependent on the cage type, the net
type and the strength of the current. By helping to maintain the net
shape in strong current conditions, the cubic enclosed volume is maintained
and the fish will not suffer the net abrasion induced trauma which
could otherwise occur.
Kames has pioneered and developed the design of
the ring and has introduced it to many markets such as Chile, where
it has now become a standard piece of equipment, particularly on
the large 100 and 120 metre cages. Built on site by Kames engineers,
the rings can be made to fit any size of circular cages with the
weights dependent on site conditions.
Material Specification
180 or 200 mm SDR 11 PE80 pipe dependent
on cage model with internal steel weights and external galvanised
steel brackets. The weight of a ring will depend on the conditions
experienced at each particular site.

Top Net Support
At the opposite end of the cage you
can better aid predator control by utilising a top net support in
conjunction with predator nets as shown.
