Fisheries Emmissions

In the article "Fisheries Emissions Rising Despite rect efforts"  written by Bethany Lindsay explains the findings about a study on fisheries and their greenhouse gasses emmisions. According to the University of B.C. research, harvesting crustaceans such as shrimp is creating a bigger carbon footprint. From 1990 to 2011, there has been an increase in carbon footprint of around 21 percent per tonne of fish. The study’s leader Robert Parker said that he didn’t really think this result was actually considered bad. A lot of fisheries have attempted lower their fuel consumption, but it is very expensive which makes it harder for them. The increase in carbon footprint was not expected to cause that much of an impact. It is also considered easier to fish because the fish all swim together while it is harder to catch lobsters because they are solitary creatures which requires much more gas. After researcher were made, around four percent of the worlds emissions come from food production. Around 49 per cent of fishing emissions come from only five countries which includes China, Indonesia, Vietnam, the United States and Japan. It was also said by Parker. To reduce the amount of carbon footprint used, there are other fishes than can be fished which are more environmentally friendly. Even through fishing has a carbon footprint, they produce less than half the amount of gasses as beef, lamb, and pork farming. On the other hand, shrimp and other crustaceans produce around the same amount of carbon as beef and lamb.


In my opinion, I believe that it is important to understand what causes greenhouse gasses and to also look at less impactful solutions, but it is hard for companies that are so big commercially to be able to produce so much. Realistically, it is hard to be able to supply as much as the population demands if companies focus more on the greenhouses gasses they generate.



Hello Daija, I have selected to respond to your article because the fishing industry, especially in Canada constitutes for such a large amount of our food production. To add, Canada ranks 6th in the world for seafood exportation in an industry totaling 4.2 billion dollars for the country. Particularly, your article signals an alarming trend in the continued increase in fishery emissions by 21% since 1990. Also, it's interesting to read about how certain types of crustacean animals produce more emissions than others. Perhaps a way to mitigate the effects of fishery extractions could be to enforce a regulation that set a limit on the more emitting types of fish, thus reducing the overall impact on the environment. I agree with you when you state how, ultimately companies that produce so much and require output for the demand need to use more expensive alternatives when they are focused on making the most money possible. Since fish swim together it is a logical solution to exploit from this instead of fishing for lobsters that swim individually and require more complex solutions. Also, I believe the solution for such a problem should come from the countries who emit the most, those being China, Indonesia, Vietnam, United States, and Japan. Finally i'll end by mentioning a rather creative approach to the problem of enhanced fishery emissions. An article on presented hybrid energy as profitable alternative seeing as “[t]he Master's student estimated that by using wind turbines and PV panels in addition to a diesel generator for handling the energy peaks, farms can reduce their CO2 emissions by almost 50 per cent, and a typical fish farm will at the same time be able to cut costs by 16 per cent”.
