Electrofishing. Scientists carrying out a population and species survey using electrofishing equipment. Electrofishing is a fishing technique that uses direct current electricity flowing between a submerged cathode and anode. This affects the movements of nearby fish so that they swim toward the anode, where they can be caught or stunned.
Electric pulse fishing is a fishing technique sometimes used in trawl fisheries which produces a limited electric field above the seabed to catch fish. [ 1] The pulse trawl gear consists of a number of electrodes, attached to the gear in the tow direction, that emit short electric pulses. The electrodes replace the tickler chains that are used ...
Electric fishing. Electric fishing can refer to one of two methods of fishing: Electrofishing, used to draw fish to an anode to be captured. Electric pulse fishing, where an electric pulse is generated above the sea bed to disturb fish to be captured.
Established on the Central Coast in 2007, the program is a ‘community-based science program involving researchers from six California universities and surveyed 16 Marine Protected Areas using 31 ...
The population estimated from electrofishing in 1986 was about 1,000, but subsequent drought conditions probably reduced the population to about 250 in the early 1990s. Much of the upper watershed of By-Day Creek has been a refuge for LCT managed by the California Department of Fish and Wildlife since 1979, and these fish are used to restock ...

e. DNA barcoding methods for fish are used to identify groups of fish based on DNA sequences within selected regions of a genome. These methods can be used to study fish, as genetic material, in the form of environmental DNA (eDNA) or cells, is freely diffused in the water. This allows researchers to identify which species are present in a body ...
