How Global Warming Affects Lobster

Does Global Warming affect when the lobsterman can fish or not?
Yes, Global Warming makes it so that the lobster season runs longer than usual and also starts earlier than usual. This is good for the lobstering industry because there is more time that the lobsterman have to make money on their boats. In 2012, the lobster season opened 2 1/2 weeks earlier than usual and ended almost a month later.

How does global warming directly affect the Lobsters?
There are many ways the lobster could be affected by global warming. Lobsters like to be in warmer waters. This means that lobsters will be more spread out and up north more than they are now. Global Warming also has some bad affects on the lobsters. Global warming is Co2 in the air that is heating up earth and changing the climate. When the Co2 gets in the water, the calcium carbonate starts to go away. Coral reefs need calcium carbonate to survive and without it, they will die. Coral reefs are home to many lobsters and other sea life. Calcium carbonate is what lobsters need to harden their shells. With low amounts of calcium carbonate, they have to work very very hard to strengthen their shells. The lobsters working too hard causes them to not eat because they are too worn out.

Where does global warming have the most impact on lobsters?
The Gulf of Maine has seen the biggest impact on the lobsters. Scientists say that there has been a steady increase in water temperatures in the Gulf of Maine. This water temperature change has two affects on the lobsters. The first one is that the warmer water makes and increase in plankton and zooplankton, which is what lobster larva (baby lobsters) eat. This is good for the lobster larva because more of them will survive and become full grown lobsters. The second, is that the number of lobsters in the area will increase. Lobsters like warmer waters and with the water temperature rapidly increasing, lobsters will come from all over. This is great for the lobster fishing industry.

What does Global warming mean to the lobstering industry?
An article from 2010 says that high temperatures were killing off all of the lobsters from Long Island, NY all the way to Buzzards Bay, MA. The government threatened to shut down all lobstering in this area for 5 years because of the all time low number of lobsters. Less numbers in lobster have been trending the since 1997 when lobstermen brought in 20 million pounds of lobster as to 1998 they brought in 5 million pounds. This really has a bad affect on the lobstermen of these areas because they cannot do their jobs and make money to support themselves.
