Impact of carrier on ammonia and organics removal from zero-discharge marine recirculating aquaculture system with sequencing batch biofilm reactor (SBBR) University of Antwerp
Marine recirculating aquaculture system (MRAS) is an effective technology that provides sustainable farming of food fish globally. However, dissolved organics material (chemical oxygen demand, COD) and especially ammonia are produced from uneaten feed and metabolic wastes of fish. To purify the MRAS water, this study adopted a sequencing biofilm batch reactor (SBBR) and comparatively investigated the performances of four different carriers on ...
Simultaneous biomethane production and nutrient remineralization from aquaculture solids Ghent University
The rapid expansion of the aquaculture industry has brought about a heightened focus on the waste produced by high intensity fish farming. In closed-containment, recirculating aquaculture systems (RAS), fish solids are mechanically separated and/or coagulated before being disposed as waste. Subsequent revalorization is typically limited to the direct dispersal of aquaculture solids onto agricultural fields. Here, we developed a novel, continuous ...
Evaluation of the influence of light conditions on crayfish welfare in intensive aquaculture KU Leuven
During the last years, evidence has arisen for the ability of crustaceans to suffer from stress and noxious situations. This has led to an increasing public concern for crustacean welfare. Due to the interest in intensification of crayfish aquaculture, the question arises whether artificial culture conditions may impact these crustaceans’ welfare. We evaluated the effect of six light conditions on noble crayfish (Astacus astacus) behaviour in a ...
Optimized Screening Methods for Investigation of the Larval Settlement of Lanice conchilega on Artificial Substrates Research Institute for Agriculture, Fisheries and Food
The Belgium sandy coastline is very vulnerable to erosion; therefore, development of sustainable and nature-based coastal protection solutions is important. Enhancing the settlement of the ecosystem engineer Lanice conchilega (Pallas, 1766) which stabilises the sediment bed, is a possible solution. In order to enhance larval settlement by artificial substrates in the field, efficient methodologies are required to screen a wide range of ...
Distinct dynamics of Vibrio parahaemolyticus populations in two farming models Ghent University
Aims: Despite the recent prosperity of shrimp cultivation in China, very little is known about how different shrimp farming models influence the dynamics of Vibrio parahaemolyticus populations and the antibiotic resistance of this bacterium. Methods and Results: To this end, we conducted continuous surveillance of V. parahaemolyticus on four farms over 3 years: two traditional shrimp farms with daily water exchange and two farms operated in the ...
Process optimisation for the reuse of growth medium in the cultivation of marine microalgae in a closed photobioreactor University of Antwerp
Microalgae have a wide range of applications in industries such as feed and aquaculture, functional food, chemicals, pharmaceuticals, cosmetics and biofuels. Despite their high potential, widespread large-scale cultivation of microalgae especially for low-value applications struggles to get off the ground. To increase the economic viability of bulk cultivation, production costs need to be reduced. Recycling growth medium not only allows ...
Replacement of fishmeal using poultry-based protein sources in feeds for pikeperch (Sander lucioperca, Linnaeus, 1758) during grow out phase Ghent University
A 61-day growth experiment was carried out to evaluate the potential of a poultry-based protein (PBP) comprising of feather meal (FeM) and poultry meat and bone meal (PMBM), as a fishmeal (FM) substitute in diets of juvenile pikeperch (Sander lucioperca, L.). Pikeperch (initial body weight 113.12 g) were randomly distributed in groups of 250 fish in twelve 1.8 m(3) circular recirculating aquaculture system (RAS) tanks, and fed four ...
