Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

Culture of marine finfish species is expanding with emphasis on Atlantic cod production in northern Europe. These new species have their own ectoparasite problems requiring treatment and the use of wrasse is highly successful in controlling sea lice without adding pharmaceuticals to the marine environment (e.g. Deady et al., 1995). To establish a cleaner fish production, the first step is to develop productive broodstock and determine the management practices. In the summer 2008, wild Labrus bergylta were caught to establish an adequate breeding population (Ottesen et al., 2008). These preliminary studies were conducted to identify potential problems regarding the domestication of the ballan wrasse. Fish caught from the wild have difficulty to adapt to transport and / or captivity. As a result, negative indicators have been observed such as interspecies aggression, reduction/lack of maturity, reduced appetite and diseases. The work reported here focuses on this last point and reviews the potential of microalgae to reduce the bacterial disease pressure on L. bergylta in captivity.

During the past decades, many new software tools were developed to be used for agricultural research as well as for decision making. For example, crop and whole farm system modelling, pest and disease warning models/algorithms, models for irrigation scheduling or agroclimatic indices can help farmers significantly in decision-making for crop management options and related farm technologies. The aim of Working group 1 of COST734 was a review and assessment of agroclimatic indices and simulation models relevant for various European agricultural activities. The key results, based on a survey by questionnaires among the COST734 participating countries (see: http://www.cost734.eu/) and a literature survey, are presented in this study. It includes an overview of most used agrometeorological or agroclimatic indices and process oriented crop models for operational as well as scientific applications, an analysis of the limitations for applications and an overview of spatial applications in combination with GIS and remote sensing in Europe. The COST734 survey showed for example, that research activities regarding the development of agroclimatic indices in Europe are focused on indizes on drought, phenology, frost and heat stress. Process oriented crop models are mainly applied for wheat and maize, which is related to their importance in European crop production. In many cases there are still limitations of crop model applications in Europe, which often are related to the availability of input data. Spatial crop model applications including a combination with remote sensing data are still rare. There are a number of different models and indices in use, varying by regions and countries. From the survey it can be concluded that there is a need of standardisation and harmonization of applications of agroclimatic indices as well as crop models in Europe in order to allow inter-comparison of the results and to improve the interpretation of results.

En forbedret tørråtevarslingsmodell er utviklet basert på forsøk med sporefelle og fangstplanter. Modellen beregner risikoen for sporeproduksjon med påfølgende sporespredning, overlevelse og infeksjon ut fra klimadata på timebasis, forutsatt at det er tørråtesmitte i området.

Mål og metode: I denne rapporten for Buskerud presenteres materiale som er samlet inn i forbindelse med etableringen av et arealregnskap for Norge med basis i en nasjonal utvalgsundersøkelse av arealdekket. Materialet omfatter 49 utvalgsflater lagt systematisk ut over hele fylket. Disse flatene utgjør en liten, men likevel statistisk forventningsrett utvalgsundersøkelse av arealdekket. Spesielt vil materialet gi opplysninger om utmarka som utfyller registerdata og data fra andre undersøkelser. For arealtyper med mindre arealdekning enn 5 % vil usikkerheten være stor.....
