Guide: What kind of cleaner fish shed should you choose?

Cleaner fish sheds come in various types and models. Even though the sheds often have similar characteristics, it is important to find the right design to make the operations on the pen as good as possible.

cleanGOOD – Main shed

 
Single curtain shed
A single curtain shed is easy to maintain. You can let the shed dry on the edge of the pen when it is time to clean it, and you do not have use a crane boat to pull it up and down.

A single curtain shed is suitable for sites with smaller amounts of cleaner fish in the pens.

Twofold curtain shed
A twofold curtain shed is split in the middle, allowing you to pull one part of the shed to the side and dry it one part at the time. This way, you will always have a shed in the sea. 

The curtain shed is easy to maintain. You can let the shed dry on the edge of the pen when it is time to clean it, and you do not have to use a crane boat to pull it up and down.

A twofold curtain shed is suitable for sites with moderate amounts of cleaner fish in the pens.

Fourfold curtain shed
With a fourfold curtain shed, you can let a wall of sheds dry along the edge of the pen at all times, without losing the corridor effect.

The curtain shed is easy to maintain. You can let the shed dry on the edge of the pen when it is time to clean it, and you do not have to use a crane boat to pull it up and down.

A fourfold curtain shed is suitable for sites with large amounts of cleaner fish in the pens.

Panel/crane sheds
Panel/crane sheds have been constructed to endure more fouling before cleaning. The result is longer calm periods for the cleaner fish compared to what it would get if you had used curtain sheds with more frequent drying intervals. 

With panel/crane sheds you will have to use a crane boat and/or onshore service to handle and maintain the sheds. However, you can look forward to efficient shed switches with very limited “downtime”. Panel/crane sheds can easily be adapted to smaller, moderate or larger amounts of cleaner fish by adding or extracting panels.

Additional sheds

 
liveGOOD – Resting sheds
For sites that are exposed to strong currents and where lumpfish are used as cleaner fish, it is necessary to install resting sheds. The resting shed provides a safe place to rest for the lumpfish during strong currents, preventing it from being pressed against the net wall.

The resting shed should be installed in the area where the current is exiting the pen, preferably spliced in layers to create the best possible coverage.

leadGOOD – Bottom/Wintering sheds
Bottom/wintering sheds should be used in all facilities that have cleaner fish caught in the wild. The shed will lead the cleaner fish towards the main shed and will also provide a safe place for the fish to hibernate.

Bottom/wintering sheds should be used both during summer and winter.
