We raise sole

We follow their growth  FROM THE DAY THEY HATCH  until the fish are ready for  YOUR TABLE.

We look after their wellbeing

Because well treated fish are  HAPPIER FISH. And they taste better too.

We know that well-treated fish feel more comfortable, grow quickly and healthily and consume fewer resources – the result is a higher quality food.
It is for all these reasons that we are dedicated to ensuring the best quality nourishment for our fish, delivered in a way they enjoy, maintaining the water conditions where they live at an optimum for the species and continuously researching the best ways of keeping and handling the fish.


Our facilities

Two different facilities to care for our fish RIGHT THROUGH THEIR GROWTH STAGES.

A sustainable business

Are the cornerstones of our work.


We believe that the quality of our staff is key to our success and we have a dedicated team to look after our fish.
More important than a formal management system is the care that each employee takes in their role; this passion is reflected in the quality of the final product.


The production system we choose (RAS – we continuously treat and recycle the water in which the fish live) requires a level of training, planning and control not normally seen in this sector.
This system enables us to better forecast production, minimizing the risk of supply failure and so managing the relationship with our customers more effectively.


The stable environment in which our sole are kept allows them to grow more with fewer resources. Furthermore, it means that our fish quality is not affected by the seasons of the year, water temperature, sea conditions or by their own maturation, resulting in constant nutritional and sensory conditions being maintained over time.
It is this environmental stability that allows us to deliver the best fish throughout the year.


We can no longer invent the wheel but can always make it more efficient. This is what we do, continually improving all aspects of our production to everyone’s benefit: our team, our customers, the environment, society and our shareholders.
We invest considerable resources in R&D activities and we always ask the same question: can we do better what we already do well?

For all these reasons, our sole  IS MORE SUSTAINABLE  and is always of  THE BEST QUALITY.

Our cycle

By caring for our fish, we are investing in our business and working for a better world.

A passion for what we do


Having farmed different fish species in several European countries, a variety of career paths and personal journeys are core strengths in our team. We have specialized staff for growing fish for food, as well as professionals with a background in science and business.

This is how we are able to identify trends, solve problems, innovate our methods and improve the way we work. Our team is divided into different groups who either look after breeding our fish, manage their growth or provide the necessary support to allow seamless operation. Under this organization, our sole grow healthily in a comfortable environment.

Our passion is there every day in the care of our fish, so that we deliver to your table only the best taste and quality.

How does aquaculture work


Aquaculture 3.0 is a term coined by one of our shareholders to differentiate our fish farming system.
In Aquaculture 3.0 we use cutting edge technology and innovative methods to provide our sole with the best possible environmental conditions and stability, which they need to optimize their use of available resources.

In this terminology, Aquaculture 1.0 corresponds to the traditional way of raising fish in converted old salt ponds, with a minimum level of control over the fish, their environment or their biological performance.
Aquaculture 2.0 encompasses production in floating sea cages and in built tanks, generally with no water nor effluent treatment and with no real control of the environment in which the fish are kept.

Aquaculture 3.0 describes what we believe to be the optimum model to raise fish: environmental stability, animal welfare, sustainability and predictable production. For us, it’s the perfect system.


Aquaculture is important




The Marine Conservation Society  - a British NGO chaired by His Royal Highness the Prince of Wales – works to safeguard the oceans, reduce the overexploitation of fish stocks and promote sustainable alternatives to threatened species – has classified sole as an at-risk species and discourages the consumption of fish caught at sea in order to protect the species.This NGO identified a total of 20 combinations of fishing areas and fishing methods, of which 75% are considered unsustainable..
Along the same lines, the sole fishing quota approved by the European community for 2014 was reduced for the second consecutive year, with the aim of trying to restore natural stocks.
The sole Sea8 produces using water recirculation technology allows us to deliver a premium quality sustainable product, most suitable for demanding markets and sophisticated consumers.

Aquaculture Myths

Nothing like some  FACTS to put an end to some  MYTHS.

Aquaculture pollutes the environment.
Aquaculture generates waste, just as any other productive activity does. But our production system (RAS) allows us to reuse nutrients that are normally wasted. Through integrated multi-trophic aquaculture, nutrients not used by fish serve as food for other species such as oysters, algae and a variety of plants.
This combination of technologies allows us to significantly improve the quality of effluent from aquaculture and generate new products with added value. This is the mission of aquaculture in the 21st century: more sustainability generating more profit with the same resources.
Fish feed pollutes the environment and is of poor quality.
Fish feed pollutes the environment and is of poor quality. This idea reflects old practices. Feeds now used in aquaculture maintain a balance between quality and safety, both for the fish and for the consumer, all with minimal environmental impact and maximum savings.
To achieve this balance, we use raw materials from well-managed certified fish banks and trimmings from the fish processing industry, as well as selected vegetable ingredients. We are always careful to assess and ensure the nutritional value of the feeds we use.
Only certified and approved ingredients can be used in aquaculture feeds and so each new raw material has to be approved by the European Food Safety Agency (EFSA).
In addition, the veterinary authorities of each country perform periodic and random inspections for prohibited ingredients, guaranteeing a high level of food safety.
Aquaculture is fundamental to reduce the pressure on wild fisheries. Global stocks are limited and eating farmed seafood helps preserve them.
Aquaculture fish is of a lower quality.
Regardless of how they are produced, all fish are important sources of easily digestible protein, polyunsaturated fatty acids, vitamins A and D and minerals (iodine, zinc, magnesium, iron, selenium) and they have a low index of cholesterol. Aquaculture fish have a higher level of unsaturated fats that are rich in long chain omega 3 fatty acids. Their high levels of long chain omega 3 fatty acids (EPA and DHA) contribute to the prevention of cardiovascular and neurological disease and even certain types of cancer.
Furthermore, aquaculture fish are subject to regular food safety monitoring, from the production stage to the moment it arrives at the fish counter. So quality is always guaranteed.
Aquaculture fish are less nutritious and less tasty.
The nutritional quality of farmed fish depends on their diet, specially during the growth phase. The food we give our fish provides all the essential nutrients: protein, vitamins, minerals and polyunsaturated fatty acids of the omega-3 long-chain type. So eating aquaculture fish contributes to a rich and balanced diet. The European Food Safety Agency (EFSA) recommends a daily intake of 500mg of polyunsaturated omega-3 series fatty acids (EPA and DHA). Two meals per week of aquaculture fish are enough to get this amount of omega-3.
In terms of taste, most people do not distinguish between wild and aquaculture fish. In blind tastings, aquaculture fish is usually well received by both consumers and specialist tasters. Because it's good for you and tastes good, aquaculture fish is an excellent ingredient for your daily meals or for a special occasion. Farmed fish can be caught according to demand and therefore are always sold very fresh. And freshness means good flavor.

In addition to the views expressed by the group of specialists who kindlyshared with Sea8 their knowledge and experience to clarify some mythscommonly associated with aquaculture, we also suggest reading the information available on the NOAA website, the North American organization responsible for the matters related to the oceans and the atmosphere. line-height:18px
