💡It is an interactive web-based analytical platform to explore and understand the stregnths and bottlenecks of amino acids in the natural food web of global fishponds and plan way forward for precision protein feeding in pond aquaculture.

(1)   high-latitude, pelagic niche, lowland waterbodies during spring are identified as omega-3 LC-PUFA “hotspots” but progressively deteriorating over the last decades due to global change.

(2)   Zoobenthos exhibit stable ARA and EPA concentrations across latitudes but lower DHA levels than zooplankton. Zooplankton DHA content increases with latitude.

(3)   an optimum organic carbon load (8–10 mg DOC/ L) and reduced phosphorus–driven eutrophication (< 20 µg TP/ L) are needed for maximized EPA (> 20 µg/ g dry matter, DM) and DHA (> 10 µg/ g DM) concentrations.

(4)   Temporal trends indicate a decline in DHA and EPA in highland zooplankton over recent decades, likely influenced by climate change, while eutrophication-driven shifts contribute to seasonal DHA reductions in lowland lakes.

The pond fish nutrition group has a new grant! INTERREG AT-CZ project called "CARMA". Low trophic level "C1 gas protein". That is Methanogenic bacteria inspired from European fishponds, wastewater treatment and grown on industrial C1 gas effluents.

Mitigating greenhouse gas to useful amino acids supplements for aquafeed - which is anyway part of the natural food chain in ponds. Special bioreactors to avoid Sulphur-limitation/ Methionine deficiency and possibly fortified with priority minerals (such as Selenium) to improve competitiveness.

Open to do joint meeting/ workshop, data and biomass exchange? We are open to do clustering with other sucessful EU/ ERDF/ INTERREG/ H2020 grants having a similar focus. Subscribe via scanning the QR code to receive updates and contact for clustering ( kroy@frov.jcu.cz / sabine.spiess@k1-met.com).
