The Environmental Impact of Fisheries and Fish Farming on a Global Scale

Survey report Impacts on fisheries and fisheries environments around the world At Oceanography class trips in La Jolla, California, we conducted a day's test and observation of marine life on an ocean college ship. In order to collect samples of various fish species in the area, we dragged a big web into the water, and the volunteers said that they do not do this often because they were environmentally destructive It was. I found that the fishery in this way could be harmful not only to fish but also to the marine environment itself.

The demand for fish worldwide is increasing year by year, but the fishing industry around the world is collapsing due to unsustainable fishing methods. When buying fish, please be sure to capture or cultivate fish in an environmentally friendly way. Do not you know what kind of fish to buy? This little helper makes you more relaxed. The sea absorbs more than 25% of the body's carbon dioxide emissions. This leads to "ocean acidification", which can damage a wide variety of marine species. Stopping ocean acidification is the same as dealing with climate change. We need to reduce global CO2 emissions. On an individual level, this is a great way to choose your bike or public transport instead of your car, to reduce your overall energy consumption, to use green energy like the sun and wind energy, It means to be more conscious when you eat and shop. please choose.

Even breeding carnivorous fish such as salmon does not always reduce pressure on wild fisheries. For carnivorous fish, usually fish meal and fish oil extracted from wild feed fish are given. The global aquaculture revenue recorded by FAO in 2008 is 33.8 million tons, estimated at about 60 billion dollars. Available foods usually restrict the growth of zooplankton, such as planktonic algae or crustaceans and mollusks that feed on benthic animals. Tilapia can directly filter phytoplankton and increase yield. Pond water fertilization by artificial fertilizer mixture (potassium, phosphorus, nitrogen, trace elements etc.) promotes photosynthesis
