Climate Change In Aquaculture Essay

1008 Words5 Pages

It is now accepted that climate change is one of the greatest threats facing mankind today and we cannot evade it, for it is a consequence of many years of our negligence and excessive harmful gas emission from energy generation, transport, different industries and even our improving technology. As a result, we are now facing these upshots of climate change. And these upshots include those on fisheries and aquaculture- which is the main topic of this research. Climate Change affects the survival, growth, reproduction and distribution of individuals within species but impacts can also be shown at the level of populations, communities, or entire ecosystems. Some anticipated consequences are falling of fish productivity, migration of species and localized extinctions, as well as the increased risk that are associated with extreme climate events like storms and hurricanes. The reef-based fishing industries …show more content…

This is because of the inherent unpredictability of changes in climate and the links that implicate fishery and aquaculture. The impacts on fisheries are due to a variety of direct and indirect effects of a number of physical and chemical factors, which include temperature, winds, vertical mixing, salinity, oxygen, pH and others. Direct effects include reduced precipitation and greater evaporation, while indirect effect is when more water is used for irrigation to offset reduce precipitation. These direct and indirect effects contribute in the changes of distribution, productivity and extinction. Global warming may have even greater repercussion for marine ecosystems than for terrestrial ecosystems (found on landforms) because temperature influences water column stability, nutrient enrichment, and the degree of new production, thus, the abundance, size composition and

    The increase in the changes of climate is affecting the delicate coral reefs. Coral reefs depend on a balanced temperature to thrive. The increased water temperature due to global warming are causing the coral to become bleached. They turn white and die. This also kills the wildlife and algae that live in them.

    This article presents the impact of climate change in the Chesapeake Bay. Scientists predict climate change will increase the water temperatures, CO2 levels, and stream-channels which will affect the Chesapeake 's physical, chemical, and biological processes. Greater CO2 levels will increase the water temperatures and the precipitation amount and precipitation intensity. Excess precipitation will create stream-channels to the bay, and increase the fluxes of NPS sediment, phosphorus pollution, and nitrogen. Stream-channels deliver sediments and nutrients to the bay, driven to non-point sources.

    People may know about climate change and the drastic changes it is having on the environment, but what they may not be aware of is that another degree increase in the world’s average temperature will cause even bigger problems for people all over. Climate change is long term shifts in temperature and patterns in the weather. Greenhouse gasses, gasses that trap heat in the atmosphere causing it to warm up are at an all-time high due to humans and the amount of fossil fuels we use. The most crucial result of climate change is global health, but animal endangerment and the rise in sea levels are also very important effects.

    Imagine if all of Florida disappeared under the water. Millions of people would need to migrate up to other states, likely causing population issues in some places, and the culprit of the disappearance: Humans. More specifically, climate change caused by humans. Climate change is caused by greenhouse gas emissions, and that makes the atmosphere trap heat from the sun in our atmosphere. This causes the global temperature to slowly increase.

    In Newtok Alaska, the villages are built on frozen solid soil. With the climate changing the soil is thawing out and the ice is melting. Some villages have even begun to sink in into the ground. Now the villagers must relocate to higher ground and must rebuild on solid ground that won't be affected by the climate change. Humans are the main cause of global warming, but at the same time we are the only ones who can stop it.

    The lack of breaths per minute as the temperature is decreased indicates that goldfish are ectothermic organisms. Although other environmental factors may play a small role in the respiration rate of aquatic ectotherms, the experiment provided evidence that water temperature was greatly responsible. The biological significance of the experiment was that scientists may conclude that many other freshwater fish become inactive during the winter months due to the drop in water temperature. The results of the experiment may be applied to the real world by concluding that perhaps water temperature is responsible for why sport fishing in Louisiana occurs predominantly in the spring and summer months; the water is warmer and the fish require more food to maintain their respiration and metabolism. This experiment could have been adapted or modified to show that as respiration rate decreases, so does the fish’s metabolism

    Many animals, whether they live in the ocean or the arctic are affected by climate change. Climate Change affects everybody in the world, even though some choose to ignore it, which is why it would be in humanity’s best interest to come together and find a solution. Burning fossil fuels and the increase of greenhouse gases is causing the earth to warm. Although this gas is the source of the problem we still need it, without this gas the earth would be very cold.

    Earth’s climate has been changing over the last few decades, with the global temperatures rising at a high rate (Corell, 2006). Some of these climate changes are due to natural causes, although the strength at which temperatures are rising indicates human influences, such as increased carbon dioxide emission, as well as other greenhouse gases. Climate change particularly affects the Arctic region, where warmer temperatures are causing decrease in sea ice extent and thickness, permafrost thawing, coastal erosion, changes in ice sheets and shelves, and consequently, changes in the distribution and reproduction rates of Arctic species (Corell, 2006). Warmer temperatures have led to increased melting of glaciers and sea ice, and shortening of

    Certain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.

    The effects of the climate change are undeniable in the scientific research. The Intergovernmental Panel on Climate Change and other meteorological organizations measures the temperature of the earth on the daily basis and has indicated the potential increase. Furthermore, the dramatic decline in ice and glaciers in the North and South Pole verify the rising temperature and its impact on the sea level.
