Pump for Sea Lice and Plankton

23.585 - Pump for Sea Lice
23.586 - Pump for sea lice and plankton:

Our pump is designed for collecting and analysing the amount of sea lice, and it can be used in vertical as well as horizontal orientation. Standard delivery comes with a mesh size of 140 µm, but a huge variety of mesh sizes is available, so the pump can also be used for plankton analysis. The pump comes with a time lapsed trigger allowing programmed pump sessions. Furthermore it's very easy to replace the battery for an extended operation time.

Salmon farms across the world are suffering from infestations of Lepeophtheirus salmonis, a sea louse that targets salmonids (the family of fish that includes salmon).

Sea lice are copepod crustaceans. They have been around for millions of years and have adapted to live on salmon, feeding on the fishes' skin and blood to survive. The lice have a short, free-swimming larval phase, when they need to find and attach to a fish host.

The infective larvae are less than a millimetre long, so in the wild finding a host is a difficult part of the life cycle, but in aquaculture, fish are kept at unnaturally high densities, so the parasites will exploit that, and their lives become easy.

Although they are small, the lice can cause catastrophic damage commercially. Infected fish can't be sold due to the lesions the parasites cause. But the health of the fish is also at risk. In extreme cases, an infestation can cause mass mortality.
