In the beginning, Inagro needed a quarantine as it purchased each year new Pikeperch juveniles. This always had the potential danger of bringing in disease. Today Inagro’s pikeperch production is a closed loop. We only work with in-house produced eggs, larvae and adult fish. Inagro has its own broodstock, off-season reproduction and larvae. As a result, we could use the quarantine room for a new aquaculture system.
This new system needed to serve two purposes:
- Possibility to conduct feeding trials with an option for digestibility research.
- Be the optimal system for fish from 0.1g to 10g, a grow-out for juveniles.
We have designed and built our own system, after half a year the first feeding trials are taking place. The system is a RAS with moving bed bioreactor, drumfilter, oxygen injection, UV, T control (2-30°C) and 12 tanks (700 liter each) with cooled feces collector at the outlet.
Today a trial on commercial feeds is running to an end, results are being gathered as I am writing this text. This will be followed by a test of our new cooled feces collector system. As pikeperch does not really have solid feces, this last experiment could become very challenging. We hope to come up with a “solid” way of gathering pikeperch feces in order to obtain data on digestibility of the feeds.
