Mechanisms of ammonia transport in marine fish with a different nitrogen metabolism. University of Antwerp

Gudrun De Boeck
Systemic Physiological and Ecotoxicological Research (SPHERE)
Ammonia toxicity is a frequent problem in aquatic environments (aquaculture, eutrophication, …) which adversely affects fish performance and welfare. Fish also produce endogenous ammonia in their nitrogen metabolism, and it is their most important nitrogen waste product. Mechanistic strategies in fish gills to cope with ammonia toxicity and transport have fascinated biologists for many decades. The recent discovery of the ammonia transport ...

Unravelling the interplay between the bacterial fish pathogen Flavobacterium columnare and the hypothalamus-pituitaryinterrenal axis of their host under acute and chronic stress conditions Ghent University

Annemie Decostere
Department of Pathobiology, Pharmacology and Zoological Medicine

demand. This proposal aims to unravel the interplay between the bacterial fish pathogen Flavobacterium columnare and the stress response mediated via the hypothalamus-pituitaryinterrenal (HPI) axis of its host under acute and chronic stress conditions. Hereby a marked contribution will be made to i) the use of the cortisol content and glucocorticoid (GC) profile of scales as a reflection of the fishU+2019s exposure to chronic stress as this ...

Bilateral co-operation: Determination of toxic compounds and metal's speciation in fish in industrial areas Hasselt University

Jan YPERMAN
Applied and Analytical Chemistry
The aim of the study is to determine toxic compounds and speciation of metals in freshwater fish collected from several industrial and agricultural areas in Dolnysk in Poland. The evolution of pollutants profiles as a function of the following factors such as location, season, fish organ, fish species will be studied. The relationship between the kind of industrial activity and the kind, form and distribution of pollutants in fish will be ...

RIver flow regulation, fish BEhaviour and Status - MSCA-RIBES Ghent University

Peter Goethals
Department of Animal Sciences and Aquatic Ecology

In 2016 serious concerns on the achievement of the EU Biodiversity Strategy 2020 targets, due to the continuing loss of biodiversity and degradation of aquatic habitats, led to the urgent adoption of a new Resolution for implementing ecosystem restoration measures. Moreover, on December 2018 the EU raised to 32% the binding renewable energy target for 2030, bringing further input to hydropower development. Meeting these targets sets ...

Win-win protein: reconciling fish protein generation and water quality management. Ghent University

Geert Janssens
Department of Veterinary and Biosciences

Garra and tambaqui are endemic fish to Ethiopia and the Amazon. We evaluated the performance, metabolic and functional effects of garra meal as feed on broiler chickens. We evaluated the effect of fish meat preservation methods on nutritive value of tambaqui fish and investigated the compatibility of beet pulp as nutrient on functional and metabolic effects of cultured tambaqui fish.

PurpleGuppy: Healthy ornamental fish through environment-friendly feed based on purple bacteria. University of Antwerp

Gudrun De Boeck
Sustainable Energy, Air and Water Technology (DuEL), Ecosphere
Ornamental fish is the third and fifth most common group of pets in the United States and the European Union, respectively, with guppy being one of the most popular freshwater tropical fish. This market and associated environmental aspects continue to grow, spurring fish feed suppliers to use novel and ecological ingredients to boost health, fitness and color. Microalgal biomass, astaxanthin and several probiotics such as Pediococcus ...

Keeping up the pace: acquiring a ZebTEC installation for cost-efficient standardised rearing of small fish model organisms. KU Leuven

Luc Brendonck
Ecology, Evolution and Biodiversity Conservation, Molecular Biotechnology of Plants and Micro-organisms
Small fish species such as zebrafish, stickleback and killifish are important model organisms in various biological research fields. All fish research, however, hinges on standardised and cost-efficient rearing of sufficient numbers of test-animals. While a growing number of ongoing research projects within the Biology Department directly relies on the use of fish-model species, current fish rearing facilities are outdated and insufficient. ...

PurpleRace: Cost-cutting raceway technology for purple microbiomes, sustainable feed ingredients for healthy fish. University of Antwerp

Siegfried Vlaeminck
Systemic Physiological and Ecotoxicological Research (SPHERE), Sustainable Energy, Air and Water Technology (DuEL)
The aquaculture feed and ornamental fish food markets depend mainly on fishmeal as protein source, yet its use is highly controversial as its production relies primarily on fish caught in the wild resulting in overexploitation of natural fish stocks. The use of microbial biomass as protein source for feeds, termed microbial protein, has the potential to mitigate this unsustainable practice. Biomass of purple non-sulfur bacteria (PNSB) is a type ...

The shift from traditional to new fish smoking technology in Ghana: Chemical and Microbiological Food Safety Implications, and Recommendations for Meeting Food Security Objectives Ghent University

Bruno De Meulenaer
Department of Food Technology, Safety and Health, Department of Food safety and food quality, University of Ghana

Ghanian population obtains 60% of animal protein from fish, mainly traditionally smoked fish. Traditional ovens and methods of smoking predispose products to chemical and microbiological hazards, thus compromising safety. A new oven has been introduced to address those safety problems. This study will evaluate the impact of the intervention on the safety of the products from a risk assessment perspective.

Fundamental relations between spatiotemporal fish behaviour and hydraulic conditions in anthropogenically impacted streams Ghent University

Ingmar Nopens
Department of Data analysis and mathematical modelling, Department of Mathematical Modelling, Statistics and Bio-informatics

In this project, the migration routes and behaviour of two fish species near hydraulic structures in the Albert channel will be investigated by means of rigorous monitoring and modelling. Fundamental knowledge on fish behaviour in relation to hydraulic conditions in these structures will be developed in order to determine the preferred and disturbing conditions to fish migration.
