A resistive counter is associated with an in-river structure, an example constituting a Crump weir. [1] The resistivity of a fish is lower than that of water. So, as fish cross this barrier, they pass embedded electrodes, and the difference in resistivity disturbs the field established in the vicinity of the electrodes, altering inter-electrode resistance.

In fisheries and conservation biology, the catch per unit effort (CPUE) is an indirect measure of the abundance of a target species. Changes in the catch per unit effort are inferred to signify changes to the target species' true abundance. A decreasing CPUE indicates overexploitation, while an unchanging CPUE indicates sustainable harvesting. [1]

Catch shares provide long-term secure privileges to participants and, in theory, an incentive for efficient, sustainable use of fish stocks. [2] Actual outcomes in terms of efficiency and ecological sustainability are varied, based on design and implementation of the program. Catch share programs generally fall into two categories.
