Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Net
A fishing net is a net used for fishing. Nets are devices made from fibers woven in a grid-like structure. Some fishing nets are also called fish traps, for example fyke nets. Fishing nets are usually meshes formed by knotting a relatively thin thread. Early nets were woven from grasses, flaxes and other fibrous plant material. Later cotton was used. Modern nets are usually made of artificial polyamides like nylon, although nets of organic polyamides such as wool or silk thread were common until recently and are still used. History Fishing nets have been used widely in the past, including by stone age societies. The oldest known fishing net is the net of Antrea, found with other fishing equipment in the Karelian town of Antrea, Finland, in 1913. The net was made from willow, and dates back to 8300 BC. Recently, fishing net sinkers from 27,000 BC were discovered in Korea, making them the oldest fishing implements discovered, to date, in the world. The remnants of another f ...

Fish Of Europe
Fish are Aquatic animal, aquatic, craniate, gill-bearing animals that lack Limb (anatomy), limbs with Digit (anatomy), digits. Included in this definition are the living hagfish, lampreys, and Chondrichthyes, cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a vertebrate, true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed placodermi, external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Labrus
''Labrus'' is a genus of wrasses native to the eastern Atlantic Ocean into the Mediterranean and Black seas. Species The four currently recognized species in this genus are: * ''Labrus bergylta'' Ascanius, 1767 (Ballan wrasse) * ''Labrus merula'' Linnaeus, 1758 (brown wrasse) * ''Labrus mixtus'' Linnaeus, 1758 (cuckoo wrasse) * ''Labrus viridis'' Linnaeus, 1758 (green wrasse) Fossil record Fossils of ''Labrus'' are found from the Eocene to the Quaternary (age range: from 55.8 to 0.781 million years ago.).

Speargun
A speargun is a ranged underwater fishing device designed to launch a tethered spear or harpoon to impale fish or other marine animals and targets. Spearguns are used in sport fishing and underwater target shooting. The two basic types are ''pneumatic'' and ''elastic'' (powered by rubber bands). Spear types come in a number of varieties including threaded, break-away and lined. Floats and buoys are common accessories when targeting larger fish. Components The basic components of a speargun are a spear, a stock or barrel, and a handle or grip containing a trigger mechanism. Spearguns are usually from long, round or roughly rectangular from in diameter/width. Types of spearguns Spearguns are, most often, divided according to propulsion method, with the two common variants being rubber (or band) powered, and air powered (pneumatic). Band-powered spearguns, which are the simplest and cheapest to maintain, with rubber being the predominant material, come in two types: those made ...

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] |
Handline Fishing
Handline fishing, or handlining, is a fishing technique where a single fishing line is held in the hands, rather than with a fishing rod like the usual angling. It is a type of angling, and is not to be confused with handfishing, which is catching fish by hand. When handlining, one or more fishing lures or baited hooks are attached to the line, and a fishing lure and often a weight and/or a fishing float can also be attached to the line. Handlining is among the oldest forms of fishing and is still practiced throughout the world today. The fishing bait can be still fished, trolled or jigged up and down in a series of short movements. Often handling is done close to the bottom of the body of water but can also be done near or on the surface. Salt water handlining Ocean handlining is often used to catch groundfish and squid but other species are sometimes caught, including pelagic fish. Sea handlining is a good way to catch larger oceanic fish. Freshwater handlining Handlini ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Reel
A fishing reel is a hand- cranked reel used in angling to wind and stow fishing line, typical mounted onto a fishing rod, but may also be used to retrieve a tethered arrow when bowfishing. Modern recreational fishing reels usually have fittings aiding in casting for distance and accuracy, as well as controlling the speed and tension of line retrieval to avoid line snap and hook dislodgement. Fishing reels are traditionally used in angling and competitive casting. They are typically attached near the handle of a fishing rod, though some specialized reels with pressure sensors for immediate retrieval are equipped on downrigger systems which are mounted directly to an ocean-going sport boat's gunwales or transoms and are used for "deep drop" and trolling. The earliest fishing reel was invented in China at least since the Song dynasty, as shown by detailed illustration of an angler fishing with reel from Chinese paintings and records beginning about 1195 AD, although sporadic text ...

Fishing Rod
A fishing rod is a long, thin rod used by angling, anglers to fishing, catch fish by manipulating a fishing line, line ending in a fish hook, hook (formerly known as an ''angle'', hence the term "angling"). At its most basic form, a fishing rod is a straight rigid stick/pole with a line attached to one end (as seen in traditional Tenkara fishing); however, modern rods are usually elastic and generally have the line stored in a fishing reel, reel mounted at the rod handle, which is hand-cranked and controls the line retrieval, as well as numerous line-restricting rings (also known as ''line guides'') that distribute bending stress along the rod and help dampening down/prevent line whipping and entanglement. To better entice fish, fishing bait, baits or fishing lure, lures are dressed onto the one or more hooks attached to the line, and a bite indicator is used, some of which (e.g. quiver tip) might be incorporated as part of the rod itself. Fishing rod acts as an extended leve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
