Journal articles Findings: Green Crab Male/Female Ratio Students at Bath Middle School went to Reid State Park to collect crab trap data. This study was conducted because we wanted to find out about the crab population. We went on Oct 24th, 26th, 27th and 28th. We used legal crab traps and sardines in oil, and also did a catch and release experiment and recorded data on the crabs we caught. I made three pie charts for 2015, 2016 and 2017 on the female and male population. The graphs show that over the years the female population has declined and the male population has risen. Currently, the green crab is a huge problem in the marine ecosystem. 2017-12-20 FlufflyCrabbyCr... 3
Journal articles Findings: Green Crabs and the Male/Female Ratio Abstract Green crabs are an invasive species. They eat soft shell clams and native crabs food, they also other marine life animals food. We used rectangular traps to catch the green crabs. We also painted the crabs backs with insta-dry nail polish so that if we got any recaptures we would know. Results that I got were for the color of the bottom of the crabs and if they were male or female. I did my research on how many male or females had a certain color. Out of all the green crabs we caught we only had one recapture and tat told us that the population was huge. 2017-12-20 Invasivecrabass... 2
Journal articles Findings: The invasive green crab Abstract Green crabs are bad because they are invasive. They also destroy the ecosystem. We used the catch and release method. We caught a lot of green crabs. Most of the crabs had orange markings. A lot also had mixed orange markings. Green crabs are bad for the environment because there are so many and they are constantly reproducing. They are also very hard to kill. Green crabs destroy eelgrass which is a common home for many animals in our ecosystem. 2017-12-20 madcrabbyz 2
Journal articles Findings:Number of European Green Crabs Caught in 2015 - 2017 at Fort Popham, Griffith’s Head and Todd’s Landing Abstract European green crabs have been wreaking havoc of the native habitat since only 2013 and they are already are severely damaging the marine ecosystem. The purpose of our study is to find out why the green crabs are extremely resilient and what we can do to the green crabs that will harm them, but not harm others native species. We used the catch and release method to fully understand the size of the population; measuring the size of their carapace, the color of the crab, the sex of the crab, if the crab was aggressive and if the there was anything that stood out about the crab. 2017-12-20 Flitterfluff 3
Journal articles findings:Why the green crab population in Todds Landing is going down. Abstract Green crabs are a very invasive species in the Maine ecosystem, but not just in Maine but most of New England. If the green crab problem doesn't get solved then most Maine fishing industries could be shut down like crabbing and clamming. In Todd’s Landing in 2015 there were a lot of crabs, but in 2016 the number dramatically decreased then went up again. There could be many reasons they weren't in Todd’s Landing that year. 2017-12-20 101SzechuanSauc... 2
Journal articles Findings: Green Crab Trap Study Abstract Bath Middle School students have gone and investigated about green crabs, and what they are doing to our ecosystem. We have gone to investigate about this problem at Fort Popham, Todd’s Landing, and Griffith’s Head to catch, graph, and study green crabs in October. Then I graphed two graphs for how much crab’s were caught in each year. And I also gave a box and whisker plots for the maximum and lower crab counts which are 119 and 34 for Griffith’s Head. And for Todd’s Landing minimum and maximum was 97 and 14. 2017-12-20 Flitterfluff 2
Journal articles Findings:Green Crab Trap Study in Todd’s Landing, Griffith’s Head, and Fort Popham, ME Green crabs are a species of crab native to Europe and northern Africa, and they have sticking around America since the mid 1800s, when they got aboard ships from Europe to America. My question is how are they affecting the marine ecosystem. We used the catch and release method to capture the crabs. The catch and release method is using a legal crab to capture the green crabs, and used sardines in oil as bait. 2017-12-20 RockCrabsClan 3
Journal articles Findings:Male Female Ratio 2017 Green Crab Trap Data The Bath Middle School 7 graders have been learning how are green crabs impacting the marine ecosystem. We have been doing this because they are eating other species and reproducing quickly. The week we went claiming we used the catch and release method. We caught the crabs with a legal trap. Another thing we did is use sardines dip in oil The data showed that there is more males than females. Also the data showed that there is lots of crabs in Todd’s Landing and Griffith’s Head. Lastly we figured out that green crabs have been living long times even without missing legs. 2017-12-20 RockCrabsClan 1
Journal articles Findings:Green Crabs Invasion Abstract Green crabs are an invasive species. We are studying these crabs and their population.The green crabs harm our ecosystem because they eat clams and small fish. We caught the green crabs by putting a trap in the water and baiting it with sardines in oil. The trap was hauled day after day and the crabs were counted. We put insta dry nail polish on the crabs to see if they were caught the following day. There was only one crab that we caught, that had paint on their shell. Everyday we checked the trap. Some days lobsters were in the trap. 2017-12-20 101SzechuanSauc... 1
Journal articles findings:Invasive Green Crabs Population on the Coast of Maine Abstract We caught green crabs to find data to hep find out how many green crabs there are. We marked the crabs with nail polish but first we had to put nail polish remover to get rid of the bacteria so the crabs wouldn't die. If we didn't the alcohol which could have potentially killed the crabs we caught. Some of the crabs we caught were aggressive and we found out that way the hard way, the crabs tried to escape and tried to pinch us. We were lucky that the crabs couldn’t pinch us. 2017-12-20 crabbydestroyers 1
