I am very good at being impatient. However, it is easier for me to be patient when I am fishing because I know if I am patient, there is a chance at some point, I will get what I want, which is a fish. For a ring of a bell, a sway of a pole or a splash in the water.

Fishing can bring you a sense of peace and keep you physically fit. You don't have to be rich to participate in the sport, but you do need certain gear. From a fishing rod to extra bait, here is a list of the things you'll need if you want to start participating in this fun sport, or if you want to get your children into fishing. http://www.huffingtonpost.com/2014/09/06/benefits-of-fishing_n_5754408.html

The availability of seafood in Canadian and Argentinean waters is also dependent on the total allowable catch allocated to Clearwater in a given area. Although the totals allowable catch in these areas and Clearwater 's enterprise allocations have been largely stable, fishery regulators have the right to make changes in the total allowable catch based on their assessment of the resource from time to time. Any reduction of total allowable catches in the areas from which Clearwater sources seafood, or the reduction of stocks due to changes in the environment or the health of certain species, may have a material adverse effect on Clearwater 's financial condition and results of operations.

According to a study done by Living Planet Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing situation is being exacerbated by non-sustainable and destructive fishing practices and unfair fisheries partnership agreements; while there are currently attempts being made at fixing these problems and their effects on overfishing, nothing has been extremely effective.

This issue of overfishing covers vast fields, such as science, humanity, economy, society and nature. The term “optimum”, in regard to the yield from a fishery, is difficult to be defined, precisely and fixedly. Generally speaking, we can describe it as follows: (Niles E. Stople, January 2009, FishNet USA)

In this essay youll learn how to fish. People think they know how to fish until they start to fish and don't catch anything but sticks. When people catch sticks they tend to lose their temper. When this happens they normally just give up and leave without even trying to catch a fish. So here are the steps for fishing.

Many breeds of fish are being captured at a faster rate than they can reproduce. Some species such as orange roughy fishing became popular in New Zealand in the 1970’s. Over time, it spread to many countries around the world. In the last 20 years, there has been a decline in catch up to 75%. It is no longer common to see in grocery stores as well as restaurants. The amounts of fish that are captured and distributed around the world are alarming opposed to the rate the fish can multiply.

In order for there to be plenty of fish in the years ahead, fisheries will have to develop sustainable fisheries and some will have to close. Due to the constant increase in the human population, the oceans have been overfished with a resulting decline of fish crucial to the economy and communities of the world. The control of the world's fisheries is a controversial subject, as they cannot produce enough to satisfy the demand, especially when there aren't enough fish left to breed in healthy ecosystems. Scientists are often in the role of fisheries managers and must regulate the amount of fishing in the oceans, a position not popular with those who have to make a living fishing ever decreasing populations.

According to the United Nations, 17% of fish stocks worldwide are currently overexploited; 52% are fully exploited; and 7% are depleted. This means that only an estimated 20% of worldwide fish stocks are not already at or above their capacity(Seafarms, 2013). Catches of Pacific herring have decreased by 71% since the 1960s, with Atlantic herring catches falling by 63%. Atlantic Cod catches have fallen by 69% in the same time(Seafarms, 2013). These are just a few of many facts and statistics on the topic of overfishing. The effects of these statistics and facts impact people’s and animal's lives around the

The overexploitation of the oceans is directly linked to overfishing. Overfishing can be defined as “fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest” (Hilborn and Hilborn, 2012). Post industrial revolution there was an increase in global fishing and consequently an increase in catches. The large scale industrialization of the fishing sector inevitably led to over-fishing, causing the collapse of many fish stocks (Pauly, 2002). Due to unsustainable fishing practices an increase in overfished and fully fished stocks can be observed over time (see Figure 1). The fishing industry has had to adapt in recent times to maintain the quantity of fish being caught, one way they have achieved this is to start fishing at greater depths, today more fish are being caught deeper than ever before (see Figure 2). Deep sea fishing is mostly considered unsustainable, (Norse, 2012) as it

MSY is extensively used for fisheries management. MSY in most modern fisheries models occurs at around 30% of the unexploited population size. This fraction differs among populations depending on the life history of the species and the age-specific selectivity of the fishing method. However, the approach has been widely criticized as ignoring several key factors involved in fisheries management and has led to the devastating collapse of many fisheries. As a simple calculation, it ignores the size and age of the animal being taken, its reproductive status, and it focuses solely on the species in question, ignoring the damage to the ecosystem caused by the designated level of exploitation and the issue of by catch.

Overfishing- to deplete the stock of fish in a body of water by too much fishing. Overfishing can be defined in many way, all of them leading to the same conclusion: Catching too many fish is bad for the environment. Overfishing is an unsustainable use of the oceans. Overfishing occurs because fish are captured at a faster rate than they can reproduce. Also advances in fishing technology and an increased demand for fish has led to overfishing, causing several marine species to become extinct. Despite counter arguments, overfishing is harmful and needs to be stopped because we are depleting our fishing industry, impacting the food web, and creating economical dangers. Without creating stricter regulations, the fishing industry will continue to diminish.
