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. I looked back at the notes from October 2016 and saw that most of the notes said they were missing legs and claws, that didn't help their survival because if a rock crab or Jonah crab or even a seagull tried to attack the green crab it would most likely end up as death to the green crab because they wouldn't be able to defend themselves. When the group I was in went to Todd’s Landing there were less crabs missing claws and more of them were aggressive, and then I looked at 2016 Todd’s Landing data and I noticed that there weren’t very many crabs that were aggressive only when they had both claws, then I realised that is a sign of weakness to the crabs because with no or only 1 claw they couldn't survive until there claws grew back that means little to no food at all which also meant no energy to defend themselves.

Comments

Not accepted for publication: I love the question posed and would anticipate multiple controlled experiments around control methods for Green crab. Background information is clearly connected to the research question. Methods were solid, but without a clear way of recording data and which data was significant to research question. Good graph, yet conclusions don't connect to the question posed, namely, "How do we stop green crab?" Love the idea and there is huge potential in this topic as a way to find out what controls would work.

The paper scored a 19/20. I would recommend for publishing. It clearly states the research question and the impact. The methods section is detailed, well explained and understandable. The conclusion includes evidence and background information to support claim. It would benefit from a foot-note with sited information.
