Consumer acceptance and risk perception of insect-based aquafeed
Insects are increasingly considered as sustainable source of protein in fish feed, but what are the consumers' attitudes towards fish fed insects instead of conventional protein sources?

Germ-free and germ-associated experimental set-ups for rainbow trout larvae for nutraceuticals-gut microbiota interaction studies and beyond (TroLar)
The aim of this project is to develop a standardized germ-free and germ-associated rainbow trout larval model systems as a means to understand the interplay among novel nutraceuticals, defense system and gut microbiota with a focus to improve larval quality.

Bio-conversion of non-food bio-resources to novel feeds for salmonids - a Nordic approach (NORDICFEED)
Nordic co-operation will improve the conditions for developing sustainable, microbial feed ingredients for salmonids produced on various residual products with the help of biotechnology.

Influence of environmental and host factors on the gut microbiome and lipid metabolism in salmonid fishes
The goal is to improve our understanding of the environmental impact and influence of host animal factors on intestinal microbiota and lipid metabolism in salmon.

Fish from ethanol residues
Project aim is to develop a sustainable protein source of high value for farmed fish, based on filamentous fungi grown on residues from ethanol production.

Recapture of manure from open fish farming cages – the missing link for a circular system
The overall goal of the project is to develop a technical system for recovering manure and fodder residues from the cage-based aquaculture in Sweden.

Screening for microbial biostimulants in aquaculture - a tool for resilient aquaponic systems
Aquaponics, integrated systems for production of fish and plants, display an alternative for production of animal protein and health-promoting vegetables. Scaling up aquaponic systems for primary production requires increased knowledge about challenges in the system regarding e.g. nutritional balance with respect to the plants, plant and fish diseases, as well as quality of the product.

Aquafresh - farmed fish as an excellent product for Swedish cuisine
SLU together with Örebro University/Grythyttan, is now developing methodology to better understand how to improve farming of fish, not only for more environmentally friendly production with high animal welfare, but also to produce a raw material of the highest gastronomic quality.

Welfare, ethics and feeding for farming and conditioning of wild fish
Grow-out or conditioning of wild-caught fish in aquaculture can increase profitability of inshore fisheries, which currently suffer economic problems, with little negative side-effects on stock status and aquatic ecosystems. However, knowledge about welfare of wild-born fish held in captivity is crucial.
-
Feasibility and potential for farming and conditioning of wild fish fed with by-catches in Sweden
Today farming or conditioning of wild-caught fish is low in Sweden and Europe in general. There are however a number of advantages in farming of wild fish compared to wild catch, such as a better control of the production chain and increased profitability. This project aims at investigating the potential for farming and conditioning of wild fish in Sweden.

LIVEFLY2fish - whole live black soldier fly in rainbow trout diets
In 2017, EU approved use of insects in fish feed. Wild salmonids and other fish naturally feed on insects throughout their lives. Feeding farmed fish with live insects could be environmentally friendly, and provide for nutrient requirements of the fish. This project will assess the feasibility of feeding whole black soldier fly larvae to rainbow trout.

Germ-free Artemia test system, an in vivo toolbox for aquaculture and cross-disciplinary research
In a germ-free animal, nutritional (and other) processes can be studied without interference from the microorganisms commonly inhabiting the gut in a conventional environment. The extent to which that process is modified by microbial action can then be examined by introducing a known microflora. Such kind of gnotobiotic tools is now recognized as essential in the advancement of knowledge on various aspects of nutrition and health.

Alternative feed to fish - Bioactive components effect on metabolism and the gut micro flora
The aim of this PhD project is to gain a better understanding of how feeding of dietary supplements, derived from new and sustainable sources, affect nutrient uptake, metabolism and gene expression and the gut micro flora of rainbow trout.

Sustainable fish farming in Rwanda: Evaluation of local feed ingredients for Nile tilapia Oreochromis niloticus
The purpose with this project is to contribute to food security through sustainable Tilapia production in Rwanda with locally available resources.
Aquaculture
Our research group aims to evaluate feed utilization efficiency, welfare, gut physiology and food safety implications when feeding alternative protein sources to species like trout, charr and tilapia. We focus on new feed sources originating from renewable waste sources, in a circular production. Two examples are insects transforming protein of low human interest and microbes forming new protein from carbon and minerals. We also study farming in a live microbial environment, so called biofloc. This research demands advanced analyses and experimental technology capacity, and we have built up an advanced fish laboratory. Our research area is stretching from feed technology, gut biota, gut health, cannulation and metabolism. Research area contact person: Anders Kiessling
