Why is it important to monitor fish health post-capture?

Monitoring fish health post-capture is crucial to ensure that the fish can recover successfully. After electrofishing, which temporarily stuns fish, it is essential to assess their physical condition and stress levels. Recovery is vital to maintain populations and ecosystem health. By evaluating factors such as injury, stress, and overall vitality, researchers can gauge whether the fish will survive after release. This practice contributes to sustainable fishing practices and the conservation of aquatic life, ensuring that fish can thrive and reproduce in their environment after being sampled.

Other aspects, such as understanding population size or evaluating equipment efficiency, are important to fisheries management but do not directly relate to the immediate health and recovery of individual fish post-capture. The primary focus should always be on the wellbeing of the fish to support long-term population stability.
