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 ...
Fly rod building is the art of constructing a fly fishing rod to match the performance desires of the individual angler. Fly rods are usually made of graphite or cane poles. There are several commercial manufacturers of fly rods, including Echo, Hardy, Zephrus, G. Loomis, Orvis, Reddington, Sage, Scott, St. Croix, Temple Fork Outfitters, and R. L.

An electronic kit is a package of electrical components used to build an electronic device. Generally, kits are composed of electronic components, a circuit diagram (schematic), assembly instructions, and often a printed circuit board (PCB) or another type of prototyping board. There are two types of kits. Some build a single device or system.
A traditional payao is a bamboo raft anchored to the seafloor with rocks. They are usually placed in very deep water, but coastal and shallow-water versions also exist. The rafts are around 4 m (13 ft) long, 1.5 m (4.9 ft) wide, and tapering at one end. Beneath the raft are palm fronds (usually coconut or nipa palm) suspended with weights ...
A newly constructed electric reef set up by Gili Eco Trust in Indonesia. An electric reef (also electrified reef) is an artificial reef made from biorock, being limestone that forms rapidly in seawater on a metal structure from dissolved minerals in the presence of a small electric current. The first reefs of this type were created by Wolf ...
