DangerousCatch-Group3

“​Our massive demands on the ocean’s bounty impacts life far beyond the shoreline: bushmeat hunting is on the rise in Ghana while in Namibia; fishing grounds struggle to recover as putrid fumes explode from the ocean depths and poison the waters; and radical new fish farms are sprouting up from Puerto Rico to Canada. Across the globe, all life is feeling the effects of overfishing. Can we protect fish in time to safeguard the ocean, life on land and ultimately ourselves? Find out how we all can make a difference.” · What are some pros and cons of fish farming or aquaculture? · What are the advantages to adding kelp and mussels to salmon farms that Chopin and Robinson introduced to farms in Canada? · Describe the offshore aquaculture that Brian O’Hanlon is doing in Puerto Rico. · What advantages are there to offshore aquaculture? · What are some of the problems with raising carnivorous fish, and how do you fix those problems? · What was one of the problems with shrimp farming that was discussed in the video?  Dangerous Catch Group 3 (Farmed and Dangerous) In the movie, Strange Days on Planet Earth - Dangerous Catch, scientists discovered interesting facts about fishing. Fish were washing up along shores around the world. Because of this, fish had been decreasing in population. Scientists believed that over-fishing could be the problem. These researchers decided to explore and experiment the ocean in order to save the fish. They have made many discoveries since then.

One of these discoveries was about aquaculture. Aquaculture is essentially fish farming. It is done in oceans around the world. One type of aquaculture is called Off Shore Aquaculture. Some advantages of this are: · It washes away sea lice that can harm fish · It allows a constant flow of water to help circulate itself ·  It is a more sanitary alternative

Scientist Brian O’Hanlon is doing research in an underwater machine called an aquapod. This is a space-aged sphere that provides a healthier environment for fish while allowing researchers to regrow fish populations. Mr. O’Hanlon is raising carnivores for his experiment. The only problem with these fish is that they create a large demand for other fish to feed on. Other scientists have solved this problem by raising herbivores, such as tilapia. Brian is trying to find a solution so that he can still grow carnivores.

Another project being performed around the globe discusses the symbiosis between salmon, mussels , and kelp. Scientists Chopin and Robinson determined that adding kelp and mussels to salmon farms would decrease pollution. These species would filter the waste that the salmon created and would create business for the industry when companies sold the excess kelp and mussels. This helped the production of salmon increase.

Unlike the salmon farm, shrimp farming has had a negative effect on the environment. Shrimp farming is leading to wide-spread destruction and also spreads disease. It destroys ecosystems, such as mangrove trees.

Because of these findings, scientists have been able to help save the environment. http://img2.travelblog.org/Photos/4975/36361/f/186572-Mangrove-Trees-0.jpg

Chopin and Robinson found that the average salmon farm produced the waste of 60,000 people. When they added kelp and mussels to their farm it not only decreased the pollution, but they were able to sell those products and added $100,000/year to their bottom line. Good Job 75/75
