1.6. Aquaculture

1.6.1. Breeding and rearing of sturgeons in intensive systems

The whole production cycle technology – from holding the brood stock until the meal size fish- is based on our results gained through research on the Siberian sturgeon and sterlet. –However, these are applicable for the most Acipenseridae fish species with respect to the biology of the species. The developed technology contains the elements of the out-of-season artificial propagation, larval rearing and weaning, nutritional requirements with respect to developmental stage and the description of the production process with biological, technological and economical apects.

1.6.2. The industrial production technology for African catfish

HAKI started the first experiments with African catfish reproduction and larval rearing during 80’s. Latter research was addressed to nutritional requirements of fish during the intensive on-grow, market size fish production in the intensive tank system, and with the combined method of rearing in tank and pond systems. The technology, that was started in the institute, and on which the later R&D activities were based, explains the whole production cycle and includes every element of the rearing technology. It takes considerable credits for a “success story” with African catfish farming in Hungary.

1.6.3. The industrial production technology for pikeperch

The research addressed to intensive production technology for pikeperch at HAKI started in the year 2000Two projects were finances by Hungarian Government and HAKI was member of the consortia of the EU financed CRAFT Project (Q5CR-2001-70594 ‘Lucioperca: Bio-economic feasibility of pike perch culture’). The R&D activity covered the aspects of artificial propagation, intensive larvi- and fingerling culture,  and habituation procedure for pond reared juveniles.
According to our results, pikeperch is not only a valuable fish for pond culture and fisheries, but suitable for the intensive rearing as well. Pikeperch reared in the intensive system with the sub-optimal and optimal conditions exhibits faster growth compared to extensive pond rearing.
Potential users: intensive fish producers, pond culturists (farmers), natural water operators


1.6.4. The introduction of tilapia to Hungarian aquaculture

Nile Tilapia has taken the attention of Hungarian fish-producers due to its easy propagation, relatively good resistance level against diseases and handling, and  delicious meat. From another side, with Hungarian natural wealth of thermal wells enables rearing of this species. The institute has done several R&D projects aiming to develop the rearing technology for Nile Tilapiawith special regards to product processing. According to our results in field of propagation and rearing, we can state that tilapia has a potential in our country. In the same manner as African catfish, rearing of this species would enable more efficient utilization of thermal wells, well known national wealth of Hungary.

1.6.5. Development of industrial fish-production technologies

With the purpose of establishment of new commercial scale aquaculture technologies we have done many investigations aiming to produce both fish and other aquatic organisms, such as crayfish, which simultaneously includes the aspects of technique, technology and biology. Additionally, our work was dedicated toward multifunctional aquaculture systems (i.e. aquaponics, systems for sea- and freshwater fish species, pond-RAS system). The results of our investigations are enabling the development of an effective operation of new aquaculture systems, from one hand, and are evolving the present production technologies for various ecological demands of both inland and marine species.

1.6.6. Introduction of new, marketable fish species to inland aquaculture

Introduction of new species and technologies with the aim to produce the exportable product is a rather laborous and time demanding working addition to the mentioned species (in frame of many VM/FVM projects) we have tested (and we are still testing) the production technology for hybrid striped bass, burbot, perch, pike, paddlefish, barramundi, red croaker and some crawfish-species.  With regard to the difficulty of the carp processing, or rather with regard to the European market tendencies to the range expansion, achieved results could be utilized by the produces who seek the resources-saving management. At the moment, our main focus is on the   BARRA_09 (NTP project) which main objective is the introduction of production technology for barramundi and red croaker in RAS.

1.6.7. The coordinated improvement of bio-fish and bio-rice production-technologies

Two linkable methods for the natural agricultural utilization of the wetland and flooding areas are rice and fish production. In the frame of the topic, we developed such a bio-fish- and bio-rice-producing techniques, which are enabling lower production-costs of the bio-products and its introduction to the market. Additionally, a new production-technology and (to this) related regulation has been set. To prove the conformity of the production, we registered the trademark.

Potential users: pond culturists (farmers), rice producers

1.6.8. Aquaculture economy and marketing
The economic and marketing research in the aquaculture covers the thrift analysis of the fish production, examines its resource-dependence and socio-economic aspects. The emphasized field of the topic was to scientifically establish the “good practice of the pond farms”, to assemble a list of the controllable requirements and analyze the criteria for its the practical applicability. We have also participated in preparing the inland regulation of the bio-fish production and in translation of international legislation. Related to the research activities of the topic, we made many market research surveys, which were based on questionnaires and personal interviews, aiming on the consumers and other participants of the distribution channels, and further conducted extensive statistical analysis with purpose to reveal the contexts of the inland fish product market.
The aquaculture economics research group prepared many previewer-analyzer studies for international organizations and for operators, concerning the Hungarian, Slovakian, Slovenian, Eastern European and European aquaculture sector.
