A collection of fishing rods A fly fishing rod Line guides on modern fishing rods Fishing with a fishing rod. A fishing rod or fishing pole is a long, thin rod used by anglers to catch fish by manipulating a line ending in a hook (formerly known as an angle, hence the term "angling").
The mesopelagic zone is the disphotic zone, meaning light there is minimal but still measurable. The oxygen minimum layer exists somewhere between a depth of 700 metres (2,297 ft) and 1,000 metres (3,281 ft) deep depending on the place in the ocean. This area is also where nutrients are most abundant.
Most adult female ceratioid anglerfish have a luminescent organ called the esca at the tip of a modified dorsal ray (the illicium or fishing rod; derived from Latin ēsca, "bait"). The organ has been hypothesized to serve the purpose of luring prey in dark, deep-sea environments, but also serves to call males' attention to the females to ...
The eyes of Winteria telescopa differ slightly from those of other opisthoproctids by their more forward-pointing gaze.. Barreleyes, also known as spook fish (a name also applied to several species of chimaera), are small deep-sea argentiniform fish comprising the family Opisthoproctidae found in tropical-to-temperate waters of the Atlantic, Pacific, and Indian Oceans.
Historically, the hadal zone was not recognized as distinct from the abyssal zone, although the deepest sections were sometimes called "ultra-abyssal".During the early 1950s, the Danish Galathea II and Soviet Vityaz expeditions separately discovered a distinct shift in the life at depths of 6,000–7,000 m (20,000–23,000 ft) not recognized by the broad definition of the abyssal zone.
Rod (optical phenomenon), a photographic artifact claimed by some to be alien life; Rod (unit), an Imperial unit of length, also known as the pole or perch; Rod cell, a cell found in the retina that is sensitive to light/dark (black/white) Real-time outbreak and disease surveillance (RODS) rod, ISO 639-3 code for the Rogo language of Nigeria
A very different technique uses land based kites, instead of boats and rods, as the mechanism for delivering the terminal tackle at the end of a fishing line. This method has been used to catch mahi-mahi from cliff tops in Hawaii. [7] In French Polynesia, mahi-mahi are caught with a harpoon. Mahi-mahi don't dive when they are pursued.
Fishfinders were derived from fathometers, active sonar instruments used for navigation and safety to determine the depth of water. [1] The fathom is a unit of water depth, from which the instrument gets its name. The fathometer is an echo sounding system for measurement of water depth. A fathometer will display water depth and can make an ...
