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. We marked the crab with quick dry nail polish and then release them to the place of their capture, the next day, we would repeat the steps and also look for nail polish on the crabs. I found that 2016 was a particularly good year for the green crabs at Griffith’s Head and Todd’s Landing but at Fort Popham the crab population went down. 2016 winter had many extremes, in some places it was to coolest and the dryest and in other places it was the warmest and wettest, on the east coast it was one of the warmest winters on record. That information would explain the population at Griffith’s Head and Todd’s Landing, but not at Fort Popham. The conclusions that I have made is that green crabs are a menace to the environment and if the ocean temperatures keep rising at the rate that they are now, the green crab population will rise with it.

Comments

Not accepted for publication: Introduction clearly states the problem and research question by connecting it to prior research and local impacts. Excellent. The research question needs refining: it seems too general when the introduction and impacts were specific to the clams. Wonderfully detailed methods section with specific and clear instructions on how the data was collected. Love how the data and graphs represent a time lapse for green crabs, but I'm missing the clam data to connect. Great potential. Love how the scientist made confident conclusions about the significance of the catch and release data, but failed to use the data to show impact on environment. Excellent effort and paper!

I would recommend it for publishing. I would give a 18/20. In the results, you did not give the mean, median, mode or range. In the methods section, you had what you needed, including the steps. In the conclusion, you did support your clam about green crabs, but it was a little bit depressing.

I rated this paper a 17 out of 20 and I would absolutely recommend it for publication. Here are my three reasons why:
1. In the introduction it stated how the issue of green crabs will directly effect the community and economy if we continue to ignore it.
2. In the methods section the strategies and observations while carrying out the experiment, in a way that made it clear to the reader why you did what you did and how it effected the experiment.
3. In the conclusion it related the answer to the essential question back to all the data represented by the graphs and tables in the results section.
