Abstract from the study
The results of the doctoral project shed more light on the development of bacterial flora in the early stages of halibut farming and the possible effects of the composition of the flora on survival and development from egg fertilization to the end of initial feeding. Severe and sudden declines are a problem in these first and most sensitive stages of rearing, and not least in the first weeks of feeding when the larvae need live feed animals. The results also show that changes in environmental factors had a significant effect on the number and composition of the bacterial flora, as it was possible to stimulate non-specific larval immunity in the treatment of food animals with hydrolysed fish proteins and improved survival in the treatment of feed animals with bacterial strains prevalent in the gastrointestinal tract. The results also indicate that the predominant part of the flora of larvae and their feed animals can to a large extent be arable.
The project was carried out in collaboration Matís ohf. and the University of Akureyri and in close collaboration with Fiskey hf. Other partners were the University of Iceland Laboratory of Pathology at Keldur, the University of Tromsø in Norway, Iceprotein ehf. and Hólar University.
The project was funded by the Rannís Technology Development Fund, the AVS Fisheries Research Fund, the Biotechnology Network in Resource Utilization, the University of Akureyri Research Fund and the KEA University Fund.
