New research reveals that fish can experience up to 22 minutes of intense pain when removed from water, challenging long-held assumptions about aquatic animal suffering. The study, highlighted by ScienceAlert, sheds light on the often-overlooked distress endured by fish during common practices such as fishing and transport. These findings not only deepen our understanding of fish physiology but also raise important ethical questions about how humans interact with aquatic life.
Fish Experience Prolonged Distress After Being Removed From Water
Recent scientific research has uncovered that fish experience up to 22 minutes of intense physiological and neurological distress once removed from their aquatic environment. Contrary to previous assumptions regarding their tolerance, studies show that the removal triggers a prolonged state of suffering characterized by rapid heartbeat, irregular gill movement, and elevated stress hormone levels. This distress period far exceeds the brief discomfort once believed, highlighting significant welfare concerns for both commercial fisheries and recreational anglers.
Key findings from the study emphasize:
- Neurological signals: Activated pain receptors continue firing for an extended time post-extraction.
- Respiratory failure: Oxygen deprivation triggers irreversible tissue damage within minutes.
- Behavioral changes: Erratic swimming and attempts to return to water persist long after removal.
