π How long can aquatic animals remain out of water before their welfare is compromised?
The answer isn't as simple as a number.
It depends on the species, the environmental conditions, and how the animals are handled.
π Fish, π¦ shrimp, π¦ crustaceans, π abalone and bivalves all respond differently to air exposure. Yet emersion remains one of the most physiologically challenging events they experience during the peri-harvest period.
Although air exposure is often unavoidable during harvesting, we still don't know exactly how long different aquatic species can safely remain out of water before their welfare is compromised.
Understanding these differences is essential for improving handling practices, reducing unnecessary stress, and advancing animal welfare across aquaculture.
π₯ In the latest video in my Aquaculture Peri-harvest Insights series, I explore what current science tells us about emersion and why it matters for both animal welfare and industry best practice.
π Watch the video and let me know: What improvements do you think are needed to better protect aquatic animals during harvest?
