Photos: German recirculating aquaculture system research facility aims to move sector forward

Take a tour of the Centre for Aquaculture Research in Bremerhaven.

Attendees of the recent EuroShrimp 2017 event in Bremen, Germany, got an exclusive tour of the Centre of Aquaculture Research (ZAF), which is run by the organizers Alfred-Wegener-Institute (AWI) in Bremerhaven.

Research at the center, which was built in 2010, focuses on the biological requirements of organisms of culturing aquatic animals or plants.

The second focus is on optimizing husbandry conditions and on technical improvements or recirculation aquaculture systems (RAS) "for a profitable and sustainable production" of aquatic species.

The center's fresh and seawater tanks allow research on both controlled and reproductive species, AWI said.

Currently, it operates seven RAS with total tank capacities from 3 to 31.5 cubic meters, as well as four racks of aquaria with volumes of single tanks from 1.5 to 200 liter.

Water quality is maintained through mechanical, chemical and biological water treatment.

For research on algae and aquaponics a greenhouse is available.

AWI's research portfolio currently ranges from testing of aqua feeds, optimization of husbandry conditions, physiology, behavior and toxicology, biochemical analyses, new species for aquaculture, integrated multitrophic aquaculture, design and optimization of RAS, as well as development and testing of instruments and innovative technical components.

One focus is on setting up small-scale "smart shrimp farming systems" as well as combining shrimp with other fish such as tilapia in the same tanks, Kai Lorkowski, technical director ZAF at AWI, said during the tour.
