Discussion

Research demonstrates a novel pump sampler for small-bodied fish, offering improved efficiency and reduced mortality.

The pump sampler matched traditional methods in capture efficiency while lowering fish mortality rates.
Efficiency comparisons showed lower mortality during sampling in tidal rivers, with 13 tests conducted from April to September 2022.
This research evaluated a centrifugal pump-based sampler designed for high-flow, high-turbidity environments.
The pump sampler enhances safety and convenience for operators, allowing for mid-sampling cleaning without disruption.

Franquet et al. (2025) studied this question.
