Key Event Relationship Description

?


  • Adequate swimming performance in fish is essential for behaviour such as foraging, predator avoidance and reproduction.
  • A decline in swim performance would cause a decrease in the essential behaviour listed above, causing a decline in population.

Evidence Supporting this KER

?


Biological Plausibility

?

  • Fish with reduced swim performance may lack the necessary mobility to avoid predators, resulting in mortality and an eventual significant decrease to population. Reduced swim performance  may also impact the fish’s ability to obtain food or prey (Voesenek et al., 2018).
  • Migratory fish species with reduced swim performance would face difficulties in completing their migration path, which could result in a lack of spawning (Voesenek et al., 2018).
