Fishing
COMMERCIAL FISHING
Commercial fishing is a worldwide enterprise that involves the capture of marine and freshwater fish and shellfish and their preparation for market.
Fishing equipment ranges from small boats whose nets are cast and hauled in by hand to factory ships equipped with the most advanced technologies for finding, harvesting, and preparing huge amounts of fish. These large catches are very costly, however, not only in the price of their equipment and fuel, but also in the depletion of fishery resources their use brings about.
The major portion of the total fish harvest consists of few fish species, which are divided into two primary groups. Pelagic species - those which live in the near-surface layers of the oceans, this include several species of herring, tuna, salmon, anchovies, pilchard, sardines, menhaden, and mackerel. Demersal species - fish that live in the near-bottom layers of the ocean, this includes cod, sole, halibut, haddock, hake, and flounder. Large catches are also made of a group of fish classed commercially as SHELLFISH - shrimp, lobster, scallops, oysters, clams, crabs, mussels, and squid. WHALING was once a major part of the fishing industry. Overfishing has endangered many whale numbers, however, and the field has lessened in importance.
Almost all large pelagic and demersal fish catches are made over or near the continental shelf, the underwater plateau around the continents and large islands. In these waters temperatures, water depths, and the currents that influence the amounts of available food create an environment that is highly favourable to the existence of large schools of fish.
The animals living in and on the bottom of the continental shelf serve as additional food sources for demersal fish. Also, most species spawn on continental shelves, and the main nursery grounds of many species are also in coastal regions. The main fishing grounds are located on the wider continental shelves of the mid and high latitudes. The single most important area is the
North Pacific, where as much as one-quarter of the world's fish catch is taken.
THE DEVELOPMENT OF THE FISHING INDUSTRY
Prehistoric people were hunters and food collectors, and they found much of their food in lakes, rivers, and shallow ...

...nd to prepare recovery plans when they have decided that overfishing is depleting stocks. In addition, the councils have granted permits to foreign countries to harvest specified quantities of certain fish species in return for a fee.
Countries that have fished under US license included Japan, South Korea, the former USSR, and Poland. In their desire to maintain the prosperity of the fleets within their regions, however, the councils have not been harsh in their recognition of depleted stocks, the quotas they set, or their preparations for stock recoveries. In 1994, however, the New England Fisheries Management Council began a process that will lead to closing commercial fishing in the Georges Bank for a number of years.
Fishing in international waters has also proved difficult to control.
While it is believed, for example, that most nations have obeyed the UN moratorium on drift-net fishing, monitoring compliance remains an unsolved problem. The US Navy's Sound Surveillance System, a 48,000-km network of undersea cable, is capable of tracking drift-net operations, but budget considerations may eventually force the sound surveillance system shutdown.
Humanity became fascinated with the idea of evolution with the work of Charles Darwin and the Scientific Revolution. People began hunting for fossils that would prove that man had an ape derived ancestry (Weiner, 1955). After various years of searching, a piece of physical evidence was found in England that was said to confirm the theory of evolution (Weiner, 1955).This confirmation came from Charles Dawson’s discoveries from 1908, that were announced publicly in 1912 (Thackeray, 2011). Dawson was believed to have found the fossil remains of the “missing link” between ape and human evolution, the reconstructed skull of Piltdown man (Augustine, 2006). The material was found in stratigraphical evidence and animal remains that were, at the time, adequate enough to confirm the antiquity of the remains (Weiner, 1955). In 1915, another specimen, Piltdown man II, was found further proving this theory (Augustine, 2006). However, this was merely a hoax proven by fluorine relative dating in 1953; the artifacts and bone fragments discovered turned out to be altered to fit the proposed scenario (Augustine, 2006). The skull found was actually composed of a human braincase that was younger than the complimentary orangutan lower jaw (Falk, 2011). Both sections of the skull had been stained to appear to be from the same person of the same age (Falk, 2011).The perpetrator of this act was never caught and there are many theories proposed for the motive of this hoax (Augustine, 2006). Many people have been taken into consideration for this crime, such as Chardin, Woodward, Hinton, and Dawson (Augustine, 2006). Nevertheless, the evidence that proves that Dawson is guilty of this crime against anthropology is quite substantial compared to the evidence...
A study performed by Martin Hausler and Peter Schmid of the University of Zurich, Switzerland, appeared in the October 1995 issue of Journal of Human Evolution, igniting controversy over the 1974 Australopithecus discoveries in Hadar, Ethiopia. The most famous of the Hadar specimens is the 3-million-year-old skeleton, “Lucy,” who was recovered by paleoanthropologist, Donald Johanson. In his article, Shreeve presents the methods and findings of Hausler and Schmid’s study as well as some counter arguments from other scientists in the field.
“Analyses of the hominid indicate that they belonged to a previously unidentified species, which anthropologist Yohannes Haile-Selassie of the Cleveland Museum of Natural History and his colleagues are calling this species Ardipithecus Kadabba. Previous fossil finds from the identical genus has suggested that hominids called kadabba were instead a subspecies of the only other known Ardipithecus species, Ardipithecus ramidus”(Bower 2004). This new hominid is being addressed presently as Ardipithecus ramidus kadabba. “While Ardipithecus ramidus kadabba is not the sought-after link—the yet-undiscovered creature that lived at the cusp of the evolutionary division between man and chimp—Yohannes Haile-Selassie, also a doctoral candidate at the University of California at Berkeley, said the hominid certainly is very close to the branching point.” (Rickman 2001)
Fly fishing is a fishing experience that is unlike any other. Being up in the clear mountain waters just casting away, time flies faster than ever. Even on a day when the fish aren't biting, and it just seems like the nothing can go right, just being there is enough to pass the day. Then there are those days when catching a fish is effortless, every knot that is tied is perfect, and every cast is better than the last one; those are the days that are unforgettable. There have been times when it seems as if it is getting dark after just a few casts. Fly fishing is something that everyone should try. Fly fishing and spin fishing, how are they different; how are they similar? Fly fishing is the casting of artificial flies that come in all styles

In Jung’s theory, he claimed the dialogue between the conscious and unconscious aspects of the psyche enriches a person. In the absence of this discourse, the unconscious processes can put in danger the personality. In this respect, Jung conceptualized individuation which ...
As archeological discoveries of bone fragments and fossils continue to support the existence of homo-sapiens
The evolution of man is constantly in question. While we are reasonably sure that modern humans and primates are both related to the same common ancestor, there is constant debate over what initially caused the two species to split into early hominids and apes. According to some, our longest and most popular theory on the division of man and ape is profoundly wrong. However, those same individuals usually offer an equally controversial theory as a substitute, one that is almost impossible to scientifically test or prove. Both the Savanna Theory and the Aquatic Ape Theory offer solutions to how and why humans evolved into bipedal toolmakers. But with enough questioning, each loses its accountability to rhetorical science.
Discovering the meaning and significance of the archetypes in one’s dreams and the dreams themselves were a sort of process that helped lead the individual towards a God. The suffering and process of analyzing the dreams and manifestations of the archetypes was crucial to resolving one’s entire unconscious and thus being at peace with oneself. When this peace was achieved, it allowed the individual to further their religious experience. Jung believed that all humans had a natural religious function and the expression of their unconscious through archetypes and dreams was crucial.

To begin, school uniforms are economic. When schools have a uniform policy, it makes it easier on the children and parents. It is convenient because a child can just go to their closet and pick out a uniform and be ready for school. It is also very cost effective. Parents can outfit their children twice a year, warm and cold weather uniforms, rather than spending hundreds of dollars trying to keep up with expensive, name-brand clothing. In addition to being economically beneficial, school uniforms also help reduce distractions in the classroom.
Jung’s theories of personality are closely related to the Freudian theories. He divided the human psyche into three categories; the ego, or the conscious mind, the personal unconscious which holds memories and such, and the collective unconscious which is the connection that all humans share. According to Jung, the collective unconscious is made up of archetypes. An archetype is the “unlearned tendency to experience things in a certain way”#. There are an innumerable amount of archetypes, which all organize experiences or materialize thoughts in their own way.
Fishing contains a wide variety of physics. when you cast you are using projectile motion and rotational motion. when you hook a fish it will often use the drag from the current agenst you. Immagine draging a fish through a swift current. You deal with the tention of your line, and the friction of the line through the guides. you also deal with friction when you use a drag.
Jung’s subjective nature as well his speculative beliefs in his experiences attempts to discover the relation between objective truth (real), psychology, and spirituality (supernatural). He placed tremendous value on the meaning of personal and collective dreams. Jung considered them prophetic and visionary for the collective nature. Conclusively, Jung’s understood the self as the principle and archetype of orientation and meaning. Jung’s development of self is a concept quite similar to Fromm, Eliade, Frankl and other humanistic driven ideas discussed prior to reach completion, wholeness, absoluteness, in essence to be harmonious with nature (fate).
The use of a boat while fishing and some of the physics applicable to boating will be included in exploring the various ways physics applies to the sport of fishing. Other topics will include the fishing rod, fishing lure, casting, and the fish itself.
