Surface Lure
A surface lure or topwater lure is a diverse class of fishing lure designed to attract predatory fish through commotions produced at (or immediately below) the water surface, imitating preys of interest swimming at the surface such as injured baitfish, frogs, wading mice, lizards and water snakes, drowning insects (dragonflies, cicadas, moths, etc.) and dabbling ducklings. These lures are preferred by some anglers due to the belief that they attract larger-than-average fish (who tend to be more territorial and unafraid of venturing out and away from underwater hidings), and from the added excitement of actually seeing the sudden splashes created by fish aggressively breaching the surface to strike the lure, in some instances even clearly seeing the fish stalking the lure before striking. Like other types of fishing lures, topwater lures produce enticing actions through passive movements when being reeled through water. They come in several different shapes and dynamic styles, a ...

Wake (physics)
In fluid dynamics, a wake may either be: * the region of recirculating flow immediately behind a moving or stationary blunt body, caused by viscosity, which may be accompanied by flow separation and turbulence, or * the wave pattern on the water surface downstream of an object in a flow, or produced by a moving object (e.g. a ship), caused by density differences of the fluids above and below the free surface and gravity (or surface tension). Viscosity The wake is the region of disturbed flow (often turbulent) downstream of a solid body moving through a fluid, caused by the flow of the fluid around the body. For a blunt body in subsonic external flow, for example the Apollo or Orion capsules during descent and landing, the wake is massively separated and behind the body is a reverse flow region where the flow is moving toward the body. This phenomenon is often observed in wind tunnel testing of aircraft, and is especially important when parachute systems are involved, becaus ...

Spinnerbait
A spinnerbait or spinner is any one of a family of hybrid fishing lures that combines the designs of a swimbait with one or more spoon lure blades. Spinnerbaits get the name from the action of the metallic blades, which passively revolve around the attachment point like a spinning propeller when the lure is in motion, creating varying degrees of vibration and flashing that mimic small fish or other preys of interest to large predatory fishes. The two most popular types of spinnerbaits are the ''in-line spinner'' and ''safety pin spinnerbait'', though others such as the ''tail spinner'' also exist. Spinnerbaits are used principally for catching freshwater fishes such as perch, pike and bass. Mode of operation Spinnerbaits attract predatory fish primarily by creating significant amount of turbulence, noise and flashing reflections with the spinning blade. The turbulence waves, in particular, provoke the fish's lateral line system, a special tactile sensory organ that enables f ...

Splash (fluid Mechanics)
In fluid mechanics, a splash is a sudden disturbance to the otherwise quiescent free surface of a liquid (usually water). The disturbance is typically caused by a solid object suddenly hitting the surface, although splashes can occur in which moving liquid supplies the energy. This use of the word is onomatopoeia, onomatopoeic; in the past, the term "plash" has also been used. Splash also happens when a liquid droplet impacts on a liquid or a solid surface; in this case, a symmetric ''corona'' (resembling a coronet) is usually formed as shown in Harold Eugene Edgerton, Harold Edgerton's famous milk splash photography, as milk is opaque. Historically, Worthington (1908) was the first one who systematically investigated the splash dynamics using photographs. Splashes are characterized by transient Ballistics, ballistic flow, and are governed by the Reynolds number and the Weber number. In the image of a brick splashing into water, one can identify freely moving airborne wate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hook
A hook is a tool consisting of a length of material, typically metal, that contains a portion that is curved/bent back or has a deeply grooved indentation, which serves to grab, latch or in any way attach itself onto another object. The hook's design allows traction forces to be relayed through the curved/indented portion to and from the proximal end of the hook, which is either a straight shaft (known as the hook's ''shank'') or a ring (sometimes called the hook's "''eye''") for attachment to a thread (yarn), thread, rope or chain, providing a reversible attachment between two objects. In many cases, the distal end of the hook is sharply pointed to enable penetration into the target material, providing a firmer anchorage. Some hooks, particularly fish hooks, also have a ''barb'', a backwards-pointed projection near the pointed end that functions as a secondary "mini-hook" to catch and trap surrounding material, ensuring that the hook point cannot be easily pulled back out once e ...

Soft Plastic Bait
Soft plastic bait, commonly known as soft lure, soft plastics, plastic bait, worm lure or just worm, is any of a range of elastomer-based fishing lures termed so because of their flexible, flesh-like texture. Soft lures are available in a large range of colours, sizes and particularly shapes, and are typically impaled directly onto a fishing hook like an ordinary fishing bait, bait. Designed to imitate bait fishes or other aquatic invertebrates (mostly worms) that are ubiquitous natural foods for carnivorous/omnivorous fishes, the realistic texture and versatility combined with simple and economical production, as well as the freedom from handling live food, live baits and having to keep baits fresh in wet containers, has led soft lures to become a standard article of modern fishing tackle, frequently used in conjunction with a jighead or as part of a sophisticated fishing rig, rig design (e.g. the Texas rig, Texas and Carolina rigs). It is also not uncommon to see soft lures impr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Fly Fishing
Fly fishing is an angling technique that uses an ultra-lightweight lure called an artificial fly, which typically mimics small invertebrates such as flying and aquatic insects to attract and catch fish. Because the mass of the fly lure is insufficient to overcome air resistance, it cannot be launched far using conventional gears and techniques, so specialized tackles are used instead and the casting techniques are significantly different from other forms of angling. It is also very common for the angler to wear waders, carry a hand net, and stand in the water when fishing. Fly fishing primarily targets predatory fish that have significant amount of very small-sized prey in their diet, and can be done in fresh or saltwater. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon) and warm-water species (notably black bass). In Britain, where natural water temperatures vary less, the distinction is between game fishing for trout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbulent
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to laminar flow, which occurs when a fluid flows in parallel layers with no disruption between those layers. Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason, turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping i ...

Winged Insect
Pterygota ( ) is a subclass of insects that includes all winged insects and groups who lost them secondarily. Pterygota group comprises 99.9% of all insects. The orders not included are the Archaeognatha (jumping bristletails) and the Zygentoma ( silverfishes and firebrats), two primitively wingless insect orders. Unlike Archaeognatha and Zygentoma, the pterygotes do not have styli or vesicles on their abdomen (also absent in some zygentomans), and with the exception of the majority of mayflies, are also missing the median terminal filament which is present in the ancestrally wingless insects. The oldest known representatives of the group appeared during the mid-Carboniferous, around 328–324 million years ago, and the group subsequently underwent rapid diversification. Claims that they originated substantially earlier during the Silurian or Devonian based on molecular clock estimates are unlikely based on the fossil record, and are likely analytical artefacts. __TOC__ Sys ...

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, chickens, ants, most spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and semiaquatic animals, which rely on both aquatic and terrestrial habitats (e.g. platypus, most amphibians). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Alternatively, terrestrial is used to describe animals that live on the ground, as opposed to arboreal animals that live in trees. Ecological subgroups The term "terrestrial" is typically applied to species that live primarily on or in the ground, in contrast to arboreal species, who live primarily in trees, even though the latter are actually a specialized subgroup of the terre ...

Butterfly Stroke
The butterfly (shortened to fly) is a List of swimming styles, swimming stroke swum on the chest, with both arms moving symmetrically, accompanied by the butterfly kick (also known as the "dolphin kick") along with the movement of the hips and chest. It is the newest swimming (sport), swimming style swum in competition, first swum in the early 1930s and originating out of the breaststroke. Speed and ergonomics The butterfly stroke boasts a higher peak velocity than the front crawl, owing to the synchronous propulsion generated by the simultaneous pull/push of both arms and legs. However, due to the pronounced drop in speed during the recovery phase, it is marginally slower than the front crawl, especially over extended distances. Furthermore, the butterfly stroke demands a different level of physical exertion, contributing to its slower overall pace than the front crawl.
