Optimal husbandry conditions, healthy animals, and innovative raw materials are prerequisites for sustainable aquaculture of animal organisms.
Although fish are already being successfully farmed from a human perspective, knowledge about animal welfare is very patchy and, as a result, production success is not at the level it could be.
Biochip-based molecular indicators can be used to measure the health and welfare of all possible aquatic organisms at various stages of aquaculture production, from hatching to the animals reaching harvest weight.
On this basis, husbandry conditions and aquaculture facilities can be improved and certified, thereby optimizing fish production processes right through to the slaughter process.
BioFiA is developing species-specific biochips for all key stages of production, initially for trout in different aquaculture systems. Particular attention is being paid to the juvenile stages of life, which are associated with high mortality rates.
Comprehensive monitoring of husbandry conditions is carried out using physicochemical and video technology for stress monitoring (including water parameters, activity patterns, and health status). This also includes state-of-the-art consideration of bacteria and parasites. Big data analyses of the monitoring data are performed using AI. This comprehensive sensory analysis allows early assessment and even prediction of animal welfare in real time.
One of BaMS's main focuses is optimizing animal welfare while improving the performance and product quality of fish in (partially) recirculating aquaculture systems (RAS).
RCAS are widely used production techniques for the aquaculture of salmonids in Germany and Europe.
BioFiA is concerned with the development of techniques for the direct monitoring of the health and stress response of fish in aquaculture.
The focus is on the stress behavior of fish in aquaculture. By improving the well-being of fish based on new, valid stress detection methods in RAS, massive advances in production performance and product quality are possible. BioFiA contributes to optimized production and sustainable utilization of aquatic biomass.
Together with the use of new raw materials such as microalgae, sustainable feed, fish, and food production can be ensured. The analysis of optimal animal husbandry, the use of innovative feed, and, in particular, the identification of highly diverse microorganism communities in KLA filter systems with optimal nitrification rates reduce the risk of bioaccumulation of pollutants despite intensive fish production. Animal welfare-friendly food production is rightly becoming increasingly relevant. The intensive production of fish as a food source in KLA in particular must therefore be continuously optimized at all process levels, right up to slaughter, in order to ensure safe, approvable, ethically and legally sound production. Optimal animal husbandry in CLAs directly improves performance-related parameters. Optimized feeding ratios shorten the growth period of fish and, with the help of suitable microbial communities, reduce the load of problematic, nutrient-rich wastewater.
Als Nitrifikation bezeichnet man die bakterielle Oxidation von Ammoniak (NH3) bzw. Ammonium-Ionen (NH4+) zu Nitrat (NO3−). Sie besteht aus zwei gekoppelten Teilprozessen: Zunächst wird Ammoniak zu Nitrit oxidiert, das im zweiten Teilprozess zu Nitrat oxidiert wird. Beide Teilprozesse liefern ausreichend Energie, die von den beteiligten Organismen für Wachstum und andere Lebensvorgänge genutzt wird. Im Stickstoffkreislauf von Ökosystemen spielt die Nitrifikation eine große Rolle, da sie das durch Destruenten aus abgestorbener Biomasse freigesetzte Ammoniak wieder in Nitrat überführt. So entsteht für Pflanzen stickstoffhaltiger Mineralnährstoff. Sergei Winogradsky kam als Erster zu der Erkenntnis, dass die Nitrifikation ein konzertierter Prozess ist, an dem unterschiedliche Bakteriengruppen teilnehmen. Er beschrieb in seinen (aus heutiger Sicht) klassischen Publikationen zur Nitrifikation nicht nur die Teilprozesse, auch nahezu alle bis heute bekannten Gattungen wurden erstmals beschrieben. Dabei unterteilte Winogradsky die beteiligten Bakterien, die Nitrifizierer, in zwei Gruppen: das Präfix Nitroso- verwendete er als gemeinsam verbindendes Element in der Gattungsbezeichnung für die…
