Math Sl Fish Production

Answer = The graph demonstrates that as the dissolved oxygen levels increase the fish population will increase. The fish show strong growth from 6ppm to 12ppm dissolved oxygen. As the levels reach 14ppm to 18ppm the have a repeating effect as 6ppm to 12ppm.. With this being said, it shows that fish will show growth progress to a certain level of dissolved oxygen and then level off.

The article “Counting The Last Fish” is written by both Daniel Pauly and Reg Watson. In this article they explain how fish are being fished out of the sea. Unlike in the seventeenth century, boats are not enclosed by schools of cod, salmon, striped bass and sturgeon. Fishing did not just recently become an issue, it has been an issue for over 50 years. All over the globe some fish are being hooked before they have time to mature.

Introduction: Today scientists put acquired data into a form of a graph. This said graph is designed to help make predictions and furthermore, study and understand the experiment and its contents at hand. The Graphing and Estimating lab involves just that. The lab is designed to collect data from several tests involving burn time of a candle.

Finally we got all our number and determine the slope, and the intercept in order to find out the forecast for the next

1. Based on the information in Table 2, it seems that the more dissolved oxygen in the water there is the higher the population of fish is.

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)

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.

Due to the importance of fishing to the worldwide economy and the need for humans to understand human impacts on the environment, the academic division of fisheries science was developed. Fisheries science includes all aspects of marine biology, in addition to economics and management skills and information. Marine conservation issues like overfishing, sustainable fisheries and management of fisheries are also examined through fisheries science.

    World production of fish is 146,27 million tons 3,36 million tons of fish produced in the

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

In today’s global economy sustainability is very important; from the biological aspect to the industries they all play a role on the marine environment. As world population increases the demand of fish rises causing overfishing. Certain laws have been placed to limit the amount of wild fishing to reduce the risk of endangerment. To meet the demand of the population, fish farms are introduced. Pollution and health related issues are part of the challenges of fish farming. Sustainability also affects social areas such as beaches.

To figure out what the predicted outcome of both the 1940 and 1944 Olympics all you have to do is plug in 1940 in to the equation y=3.02x+191, which was what was used in the graph that showed just the linear equation, to figure out this answer for the 1940 Olympics. You can do this because in this case the x represents the year and when you place in the year and solve out the equation you get what the predicted height would be for 1940. When you plug in all the numbers you get 200.6 cm as the predicted height for 1940. In the case of 1944 you would do the exact same thing but instead of plugging in 1940 in for x you would plug 1944 into the equation. For the 1944 the predicted answer for the height of the men’s long jump would be 200.3 cm.

The refined equation fits the data much more closely at the beginning, yet around the Age = 13 mark it starts to deviate again. Looking at this graph, one can come to the conclusion that it will take more than one mathematical function to graph the entirety of the data.
