devices ready to be employed. The current design of the Anti Netting Device
(AND) was developed by Alan Pitman and each unit costs currently around
MK1, 800.00 (US$13.00) each, including the securing cable and anchorage.
The transportation of the anchorages is fairly expensive as large chunks
of metal like the thresher baskets is used. The "cable" is still a bit
of an issue as it is not certain that they will last long, being just galvanized;
mild steel chain may be better as the lake is very kind to steel (the water
has a relatively low conductivity). The anchorages are only used where
there are sandy bottoms as it is possible to use the natural rock to secure
the ANDs in rocky areas.
