Green Crab Male to Female Ratio 2013 to 2017

In our green crab study we looked at the population of green crabs. We also looked at how the clam population is decreasing. For our study we used legal crab traps. We also decided to use the catch and release method. Two of the charts I made were similar. The other chart I made had drastically more male crabs than female. In the studies that were done I found that there were drastically more green crabs than any other crabs in our ecosystems. I also found that the native crab population has decreased.

Hi fred_ab,

Your article has great background information and shows how green crabs are a real issue for the community. However, your investigation does not have a clear question. What were you trying to find out about green crabs? Why is the ratio of males to females important? You can improve your work by making sure you have a question in mind throughout your investigation. That will help you determine what you did or didn't learn from the data you collected. Keep investigating! We hope to get another submission from you some day.
