Fish Farm Designing, Technology Transfer

In the search of technological and technical solutions for our clients, we think in the same way as in our own investments. We do not believe that there is an ideal technology, but rather that state of being unencumbered with the representation of individual technologies is prerequisite for success. A combination of technological and various approaches are the path to profitable aquaculture activity. The ultimate interest of the client is the only guide in the search for solutions, which could also result in investment discouragement, should we not believe in the project effectiveness. All our projects involve many experts from abroad, exchanging our experiences and knowledge, as well as basing trust on previous projects.

Despite the fact that some of the solutions seem sophisticated, we believe that all of them meet the following criteria:

  • check_circle Simplicity
  • check_circle Efficiency
  • check_circle Security
  • check_circle Economic efficiency
  • check_circle Custom design

We do not believe in type projects because the conditions of the market, the strategy of each company, the technological competence of staff, etc. are always specific, which is why G2O technology and technological solutions are always adapted to every particular situation. Regardless of the technical proficiency of the client's staff, all our systems function simply and efficiently, which is a prerequisite for making a profit.

The company G2O offers solutions in the following activities:

  • check_circle Controlled spawning of any freshwater fish
  • check_circle Breeding of any freshwater fish
  • check_circle Designing and constructing hatcheries
  • check_circle Designing and construction of teaching recirculation and aquaponic systems
  • check_circle Designing and construction of recirculation
  • check_circle Technical solutions in aquaculture
  • check_circle Designing and construction of ornamental ponds
  • check_circle Sale and consulting about the selection of aquaculture equipment
  • check_circle Sale and consulting about the selection of fish fodder

Carp farming & Recirculation for Brown Trout Breeding

Aquaculture On Our Farms

Carp farming Žabnik, Sv. Florijan, Slovenija

Find us on map

Our ponds are restored medieval ponds which were owned by the nobility. Our family started restoring the ponds in 1980 with the last one being renovated in 2009. Due to the lack of natural resources (there are only 2.5 ha of water surface at our disposal and a small water source which dries up in summer), we have developed a technology of intensive carp breeding with yield achievement from 5 to 10 t/ha per year. Besides carp, we also breed pike and pike-perch, according to the market demand we used to breed or have been breeding more than 12 indigenous species of fish intended for fish repopulation. For each species we have our own breeding shoal, we self-sufficiently perform controlled spawning, fry breeding, and breeding for consumption. Each fish grown at a carp farm is intended for fish repopulation of fishing grounds, its quality exceeding all regulatory norms and expectations (health status, condition, appearance, etc.).

The results achieved at our own carp farm prompted the implementation of our experience into large systems of Croatian fish farmers. For this reason our company G2O is currently leading carp production in the range of 2500 to 3000 t of carp per year (in comparison - the entire annual fish production in Slovenia is about 1000 t). Numerous smaller fish farms in Bulgaria, Romania and Hungary are breeding carp in accordance with our technology which is widely accessible through lectures at international congresses.


Recirculation for Brown Trout Breeding, Dvor, Šmarje pri Jelšah, Slovenia

Seven years ago we started breeding brown trout, rainbow trout and Danube salmon at the newly built fish farm in Šmarje pri Jelšah. At this location there are similar limited natural resources with 7 l/s of fresh water at our disposal. For this reason, after years of acquiring experience in classical flow-trough system we have independently designed and constructed a recirculation system with production capacity from 100 t per year. Recirculation is equipped with oxygen and ozone generators, an automatic monitoring, and regulation of the water parameters, which requires 4-hour working time maintenance. In terms of its capacity, energy consumption, and quality of the final product, recirculation is among the top of the world aquaculture. Trout are sold for consumption and fish repopulation in Slovenia and abroad.

Construction of recirculation has contributed to the development of aquaculture in Slovenia and abroad, seeing that our experience has started preventing prejudice against recirculation and encouraged many fish farmers to start with modernization of their own farms or constructing recirculation.
