Recatching wrasse in pens can be a challenging operation. And it is stressful for the fish.
Lumpfish are fond of the SeaNest hides, and they seek to return to it when they are not hunting lice. This makes it easy to catch the wrasse while it rests on the SeaNest unit.
The specially made recapture net is ready at the bottom of the hide - and is pulled up within seconds. The fish are then caught, and can easily be transported onwards. The SeaNest Recapture System comes as a separate unit that attaches to the standard SeaNest.
And it can be used again and again. Year after year.
