The sides and bottom are hung over the railing so that the sweep net forms a "bag".

This is done towards the side where the wellboat is positioned. In some cases, it is the

wellboat itself that does the job of pulling the sweep net towards the boat.

NOTE: Use caution during this part of the operation to prevent folds from forming in the

netting where fish could be crushed.

As the fish are pumped aboard the wellboat, start to reduce the volume of the sweep net

so that the remaining fish are brought closer together. This must be done as slowly as

possible to ensure that the fish have sufficient volume and oxygen. In some cases, the

oxygen level must be monitored (for example, during fish treatments) and extra oxygen

added if needed. Lift the bottom via rings/bridles using a crane (or manually if the sweep

net is not too heavy). Use the purse line that is on the outer edge of the sweep net.

When collecting fish, place the sweep net

around the floating collar, in a semicircle.

The sweep net should be arranged along

the railing on the floating collar. The

bottom is lowered down along the net

wall to get depth in the cast.

When removing small quantities of fish

(e.g. when sampling), the sweep net can

be used across just a small part of the

floating collar.

When lifting the sweep net, we

recommend using crane loops fitted

between floats along the top rope.

When starting to gather the sweep net,

start lifting the sides and bottom as well.

The extent to which the sweep net is

gathered determines how many

fish are captured in the cast.
