How Does Climate Change Affect A Fish

The questions begs a valid point and presents the challenges in the article and the Global Fishing Industry. It is evident in the case that there it has taken a significant amount of time for the notion of responsible fishing techniques. In the 50’s when the global fishing industry started picking up speed and the “Commons” precedent started taking effect with everyone trying to fish the maximum they can in order to maximize their immediate profit. It took almost three decades for communities to start feeling and exploring the effects of this overfishing and there was a need for

Numerous research and scientific studies were performed on the impact of the extensive fishing along the U.S. coastline. In 1871, National Marine Fisheries Service was launched. Their mission as stated on their website, www.nefsc.noaa.gov/history/, “…devoted to the protection, study, management, and restoration of fish.” (www.nefc.noaa.gov, 2004) While the organization contributed significantly to the study of the fish and the region, the organization was completely ineffectual in any manner in protecting the fish from over fishing and unable to get passed any effective policies to control fishing. Their biocentric view allowed the organization to study fish in a manner that many groups at the time had no concern with due to the mindset of the endless capacity of the sea. The value of many of these studies while questionable at the seriousness at the time they were taken, when looking back through the history and learning from the impact that man has on our environment. In particular, this example there is good data that supports the early thoughts of a bountiful sea of fish. As the years, progress data that clearly shows the decline of various fish species as fishing continues onward. Newton, Dillingham and Choly reported (2006), “The take of Atlantic cod, crucial to the New England economy, had peaked in 1968 at 3.9 million tons; by 1992, it was down to 1.2 million tons— a

The earth’s oceans are overfished. Nearly 80 percent of commercial fisheries are overexploited and some experts believe that global fisheries will completely collapse by 2048 (Barkin page 1). While these are just facts that tell the worst-case scenario, they should be alarms that spark change in the way we fish. This paper, however, will specifically target overfishing in the Grand Banks in Newfoundland, Canada, and analyze its impact on Earth, its Environment and Humanity. Over fishing is simply when fishermen catch more fish than are being reproduced. Eventually the stock of fish in the environment will be completely depleted. That is exactly what happened off the shores of Newfoundland in 1992. With Cod fishing at an all time high, the Canadian government discovered that the Cod population was almost exhausted. New technology and poor decision-making led to the complete destruction of the cod population in the Grand Banks and this is a mistake that we should never repeat.

The article states, “…there is ample evidence that overfishing is a significant factor in the decline of numerous species and fisheries…” (Allan et al. 1045). This statement alone summarizes the article accurately and illuminates the major problem addressed in the scholarly journal. While relaying an indistinguishable message, an article by Myers and Worm finds a different way of relaying information.

the oceans are also affected by the climate change because the climate change affects the sea animals that live on corals or any fish that feed off the

For our groups visual communication strategy we chose to create a children's picture book. Our book will target elementary school children in the North Vancouver Area, specifically between the ages six to ten years of age. Our group would start by targeting one or two elementary schools in North Vancouver as they are located near the Capilano Salmon Hatchery. The location increases the relevance and connectivity of our specific topic to the kids and their parents. Our book will focus on communicating the negative impacts that both climate change and humans have on our local salmon population, through the primary use of illustrations and short “kid-friendly” dialogue. Our report will delve deeper into the science and details of the causes, impacts, vulnerabilities and possible solutions that both local people, and larger forces (ex.government, or NGO’S) can take in order to protect Vancouvers salmon stock.

Increasing temperatures are an immediate threat to the earth and its many diverse ecosystems. Our group chose to take an in depth look at the effects of climate change on freshwater fish species, specifically on the rising air and freshwater temperatures and how they affect a cold water dwelling fish species such as the trout. We will explore how the distribution of trout has changed over time with rising temperatures, how fires due to climate change affect trout populations, and lastly what the economic impacts of increased water temperatures will be on fisheries.

It has been observed through various researches that in the last century, average temperatures across the globe increased by over 1.3°F with an increase of more than two times in the Arctic. (Bates, Kundzewicz, Wu, & Palutikof, June 2008). The results of climate change can also be seen in changing precipitation patterns, increases in ocean temperatures, changes in the sea level, and acidity and melting of glaciers and sea ice (USEPA, 2014).

Habitat loss is one of the most evident effects of climate change on animals. Forests, as well as deserts support many forms of life. It is the home of insects and animals like bears, and birds. If forests will be cleared out for the development of land for families, business and farming purposes, animals will loose their homes and food. Because of deforestation, many of the trees and the other plants that provide food to the herbivorous animals will get extinct at a faster speed. Droughts caused by global warming could dry up 90 percent of central U.S. wetlands, eliminating essential breeding habitat for ducks, geese and other traveling species (National Wildlife Federation). Climate change is the main reason to wildlife's survival and putting natural resources in danger. The change in temperature caused by global warming has many effects on the habitats of animals. The melting ice will cause the loss of habitat for species such as the polar bears, penguins, and seals. The arctic ice that is melting makes it difficult for polar bears to hunt. Warmer water will also cause the population of fish such as trout

As carbon dioxide is a greenhouse gas, increased concentrations of it have led to an amplified greenhouse effect. More solar infrared radiation is re-emitted and absorbed by the Earth, causing surface temperatures to rise. Therefore, the density of the surface waters will decrease, which means there is a greater

Reviews provided by top organization, Intergovernmental Panel on Climate Change indicate that climate change is likely to induce changes in temperatures and adjustment associated with ocean circulation, sea level, and ice coverage. Impact of climate change on marine mammals occur differently according to type of mammal and its dwelling place either deep-sea dweller or surface sea dwellers (Aguirre, Ostfeld, & Daszak, 2012). Marine species distribution is affected by multiple factors; ecological, habitat related and anthropogenic factors. Habitat distributed

The article that I came across that is related to a current topic in our class is from the Hartford Courant and it is called “No Refuge For Fish? Stressed Species Need Safe Habitat”. This article depicts the current condition of the ocean life habitat in southern New England as being in very rough shape and is still declining. This article brings to light several factors the first being that overfishing has depleted many species and there are currently requests to open up even more ground for commercial fishermen. Next comes the problem that the ocean is currently rising in temp, this is causing many species to migrate to cooler conditions of which they are used to. The last problem mentioned is that there is proposals to allow more dredging near the coast, which will only destroy fish habitat and alter their ecosystem.

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.

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

A paper published in 1898 by the Freidrich Heincke, a German fisheries biologist, influenced biologists to consider the population as the unit of study instead of the species. Insights from the Heincke’s paper helped to cultivate the influential quantitative methodology to distinguish marine fish populations. The application of statistical methods and quantification techniques in marine biology contributed to the generation of an enormous amount of knowledge related to fisheries. The shift of fishery biologists, Zoologists and wildlife agencies towards numbers and measurement in their research methodology, shaped modern Fisheries Science and contributed to solving some of the critical problems associated with fisheries. In 1957, a model published by Beverton and Holt enabled scientists to predict the future size and yields of fish stock. This quantitative bio–economic model allowed governments to make decisions on the most optimal fishing levels to help reach biological and economic goals ( Bavington, D.L.Y. 2009).
