Fishing Season
Angling is a fishing technique that uses a fish hook or "angle" (from Old English ''angol'') attached to a fishing line to tether individual fish in the mouth. The fishing line is usually manipulated via a fishing rod, although rodless techniques such as handlining and longlining also exist. Modern angling rods are usually fitted with a reel that functions as a cranking device for storing, retrieving and releasing out the line, although Tenkara fishing and cane pole fishing are two rod-angling methods that do not use any reel. The hook itself can be additionally weighted with a dense tackle called a sinker, and is typically dressed with an appetizing bait to attract the fish and enticing it into swallowing the hook, but sometimes an inedible fake bait with multiple attached hooks (known as a lure) is used instead of a single hook with edible bait. A bite indicator, such as a float or a quiver tip, is often used to relay underwater status of the hook to the surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Villa Of The Nile Mosaic Fishermen
A villa is a type of house that was originally an ancient Roman upper class country house. Since its origins in the Roman villa, the idea and function of a villa have evolved considerably. After the fall of the Roman Republic, villas became small farming compounds, which were increasingly fortified in Late Antiquity, sometimes transferred to the Church for reuse as a monastery. Then they gradually re-evolved through the Middle Ages into elegant upper-class country homes. In the Early Modern period, any comfortable detached house with a garden near a city or town was likely to be described as a villa; most survivals have now been engulfed by suburbia. In modern parlance, "villa" can refer to various types and sizes of residences, ranging from the suburban semi-detached double villa to, in some countries, especially around the Mediterranean, residences of above average size in the countryside. Roman Roman villas included: * the ''villa urbana'', a suburban or country seat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Bait
Fishing bait is any substance used to attract and catch fish, e.g. on a fishing hook. Bait items are both selected from and placed within the environment to achieve enhanced prey capture success. Traditionally, fishing baits are natural fish food such as night-crawlers, insects, worms, and smaller bait fish that have been used for catching fish. Fishermen have also begun using processed food, plastic baits and more recently, bionic lures to attract fish. Despite the importance of fish's attraction to bait, the way fish react to different baits is quite poorly understood. The various techniques and bait that a fisher may choose is dictated mainly by the target species and by its habitat. Bait can be separated into two main categories: artificial baits and natural baits. The alternative of artificial and live baits frequently demonstrate similar efficiency. The overall bait type and size will affect the efficiency and results of catches when fishing. With these two common w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Gill
Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. Within the gill filaments, capillary blood flows in the opposite direction to the water, causing counter-current exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx. Some fish, like sharks and lampreys, possess multiple gill openings. However, bony fish have a single gill op ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gullet
The esophagus (American English) or oesophagus (British English; both ), non-technically known also as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about long in adults, that travels behind the trachea and heart, passes through the diaphragm, and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word ''oesophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, “I carry”) + ἔφαγον (éphagon, “I ate”). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of fibrous tissue, and an outer layer of connective tissue. The mucosa is a stratified squamous epithelium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Jaw
Most bony fishes have two sets of jaws made mainly of bone. The primary oral jaws open and close the mouth, and a second set of pharyngeal jaws are positioned at the back of the throat. The oral jaws are used to capture and manipulate prey by biting and crushing. The pharyngeal jaws, so-called because they are positioned within the pharynx, are used to further process the food and move it from the mouth to the stomach. Cartilaginous fishes, such as sharks and rays, have one set of oral jaws made mainly of cartilage. They do not have pharyngeal jaws. Generally jaws are articulated and oppose vertically, comprising an upper jaw and a lower jaw and can bear numerous ordered teeth. Cartilaginous fishes grow multiple sets ''(polyphyodont)'' and replace teeth as they wear by moving new teeth laterally from the medial jaw surface in a conveyor-belt fashion. Teeth are replaced multiple times also in most bony fishes, but unlike cartilaginous fishes, the new tooth erupts only after the ...

Instinct
Instinct is the inherent inclination of a living organism towards a particular complex behaviour, containing both innate (inborn) and learned elements. The simplest example of an instinctive behaviour is a fixed action pattern (FAP), in which a very short to medium length sequence of actions, without variation, are carried out in response to a corresponding clearly defined stimulus. Any behaviour is instinctive if it is performed without being based upon prior experience (that is, in the absence of learning), and is therefore an expression of innate biological factors. Sea turtles, newly hatched on a beach, will instinctively move toward the ocean. A marsupial climbs into its mother's pouch upon being born. Other examples include animal fighting, animal courtship behaviour, internal escape functions, and the building of nests. Though an instinct is defined by its invariant innate characteristics, details of its performance can be changed by experience; for example, a dog can imp ...

Foraging
Foraging is searching for wild food resources. It affects an animal's Fitness (biology), fitness because it plays an important role in an animal's ability to survive and reproduce. Optimal foraging theory, Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives. Behavioral ecologists use economic models and categories to understand foraging; many of these models are a type of optimal model. Thus foraging theory is discussed in terms of optimizing a payoff from a foraging decision. The payoff for many of these models is the amount of energy an animal receives per unit time, more specifically, the highest ratio of energetic gain to cost while foraging. Foraging theory predicts that the decisions that maximize energy per unit time and thus deliver the highest payoff will be selected for and persist. Key words used to describe foraging behavior include ''resources'', the elements necessary fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scent
An odor (American English) or odour (Commonwealth English; see spelling differences) is caused by one or more volatilized chemical compounds that are generally found in low concentrations that humans and animals can perceive via their sense of smell. An odor is also called a "smell" or a "scent", which can refer to either a pleasant or an unpleasant odor. While "odor" and "smell" can refer to pleasant and unpleasant odors, the terms "scent", "aroma", and "fragrance" are usually reserved for pleasant-smelling odors and are frequently used in the food and cosmetic industry to describe floral scents or to refer to perfumes. Physiology of smell Sense of smell The perception of odors, or sense of smell, is mediated by the olfactory nerve. The olfactory receptor (OR) cells are neurons present in the olfactory epithelium, which is a small patch of tissue at the back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundbait
Groundbait is a fishing bait that is either thrown or "balled" into the water in order to olfactorily attract more fish to a designated area (i.e. fishing ground) for more efficient catching via angling, netting, trapping, or even spearing and shooting. Groundbaits are typically scattered separately from the hook and usually before even casting any rod or net, although in bottom fishing they can be deployed synchronously with hookbaits while contained inside a gradual-release device also attached to the fishing line known as a ''method feeder''. Groundbaits are often used in freshwater coarse fishing (where the target fish are commonly omnivorous or algivorous and might not be easily drawn to the hookbait), and can be custom-made personally by the angler or bulk-purchased from dedicated manufacturers. There are many different recipes of groundbaits that can be used to target specific species of fish. Groundbait can differ by the sizes of the crumbs, type of seed, colour and ...

Bait (luring Substance)
Bait is any appetizing substance used to attract prey when hunting or fishing, e.g. food in a mousetrap. Fishing The term is especially used with regard to catching fish. Traditionally, nightcrawlers, insects, and smaller fish have been used for this purpose. Fishermen have also begun using plastic bait and, more recently, electronic lures, to attract fish. Because of the risk of transmitting ''Myxobolus cerebralis'' (whirling disease), trout and salmon should not be used as bait. There are various types of natural saltwater bait. Studies show that natural baits like croaker and shrimp are better recognized therefore more readily accepted by fish. The best bait for red drum (red fish) are pogy (menhaden) and, in the fall, specks like croaker. Hunting Baiting is a common practice in leopard hunting on a safari. A dead, smaller-sized antelope is usually placed high in the tree to lure the otherwise overcautious leopard. The hunter either watches the bait from point within f ...

Casting (fishing)
In angling, casting is the act of the angler throwing the bait and hook (or a lure) out over the water, typically by slinging a fishing line manipulated by a long, elastic fishing rod. The term itself may also be used for setting out a net when artisanal fishing. The usual technique is to quickly flick/swing the rod forward towards the water, with the inertia of the terminal tackles lagging and bending the rod backward (i.e. "loading" the rod), and then use the "springing" (elastic rebound) of the rod to "whip" and rapidly sling the line forward, which in turn will hurl out the hook. There are several methods anglers use to attempt to cast farther, the most prominent of which is the shifting of body weight towards the front foot in synchrony to the forward swinging of the rod. That combined with using a longer rod, stopping the rod swing at 45 degrees, and using correctly weighted and more aerodynamic terminal tackles, will help anglers cast farther. Casting techniques Cast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quiver Tip
A quiver tip is a flexible extension to a fishing rod which is designed to vibrate, or quiver, when a fish takes the bait. The main characteristic of its design is its sensitivity. It is a popular and very effective method of bite indication both on still and running water, and is used far more often in bottom fishing. It is not used in game fishing (i.e. for salmon, trout and sea trout) and is seldom, if ever, used when fishing for very large coarse fish (e.g. carp or pike). In essence, the angler watches the tip of the fishing rod to detect bites as opposed to, say, a float or an electronic bite alarm. Description The quiver tip is a thin, light, flexible extension of the fishing rod, and relays underwater information by magnifying vibrations transmitted to the rod from the fishing line. The rod is specially designed to take quiver tips; nowadays, they are often called ''leger'' or ''feeder rods''. Very sensitive float rods can be used for quiver tip fishing, but normally ...
