WETFEED (SOFTFEED)

The feed is developed to look like the fish' natural food as much as possible, which contains about 70-80 % freshwater. It is therefore necessary to add large quantities of water to the dryfeed.
SeaFarm Solutions AS has patented a dryfeed for fish in enclosures. Water is added to the feed at the edge of the enclosure, just before feeding and the feed is made specifically to ensure high stability in water after water is added. This makes the feed soft and ensures that it stays stabile, without dissolving in the water. Up to 60 % water and additives can be added to the pellets. The feed is especially well suited to RAS facilities.

Picture 1; shows how the pellets look before and after adding water/additives. On top is the dryfeed without anything added. In the middle water and additives (carotenoid) has been added to the dryfeed, the additives being dissolved in the water. On the bottom only water has been added to the dryfeed.

Wetfeed from Seafarm Solutions

Wet feed immediately after treatment

Wet feed after 24 hours in water

In the videos above, you can see how our Seafarm Solutions wet feed looks right after water is added – and how it retains its structure, firmness, and quality for more than 24 hours. The feed is specifically developed for high water stability after hydration, making it soft and palatable for the fish while remaining intact in the water without breaking down.

This unique property allows the feed to be transported efficiently to the cages without any loss of quality, ensures improved feed intake, and reduces feed waste. The result is better feed utilization, lower environmental impact, and no risk of microplastic pollution.

Standard dry feed

In these videos, we see how standard dry feed behaves just seconds after contact with water: it crumbles quickly, loses structure, and disintegrates. This poses challenges for transporting and dispensing dry feed in cages, often resulting in significant feed loss with consequences both environmentally and economically.

BENEFITS WITH WETFEED

​

When water is added right before feeding, the feed keeps all the benefits of dryfeed, when it comes to storage and transportation.

A combination of specifically designed equipment and feed makes wetfeeding possible, simple and enviromentally sound.

The pellets used in aquaculture today are hard to ensure that they can be transported and blown out into the enclosures using strong air pressure. They are therefore not made to benefit the fish.

A number of trials with wetfeed has been made with different breeds of fish. All of them have shown good results for both growth and feed-factor.

WETFEED PROVIDES

  • Better digestion, better uptake of nutrition and increased well-being

  • Better fish health and lower mortality rate 

  • Better growth

  • Higher quality of fish

  • No microplastic pollution

  • Less energy consumption in feeding  

  • Better feed-factor

  • Possibility to add different additives to the feed, just before feeding

  • Reduced volume of functional feed

  • Increased storagestability of feed

  • Better total feeding-economy.

In addition to solving a basic need for the fish, the concept also enables - at the edge of the enclosure - the addition of other prescription content that can increase the degree of accuracy in feeding when it comes to temperature, oxygen, appetite, fish health etc.
This also applies to the addition of vitamins, energi(oils), coloring, functional feedadditives, prescriptions for oral vaccines. 
The feed can be produced in the feedsuppliers existing extruderfacility / production lines.
