Green Crab Population, Size and Impact in our Marine Ecosystem

In our Core Science we went to Reid State Park, Griffins head, and Todds landing to study the green crab population. We did this to see how many green crabs are in our marine ecosystem. The method we used to do this was a catch and release system. We did this through a Legal crab trap. We caught over three hundred crabs and only a handful came back. Most of the crabs we caught where around 7 seven centimeters long. The green crabs are killing most of the animals in are ecosystem. Also if we were to continue doing this I would put more traps out in different places.

I would not recommend this for publication because the methods were unclear and not easy to follow, the conclusion was not very clear for the reader, the graph's he used were not very precise and hard to understand.

The methods were okay containing confusing information. The conclusion simply makes no sense. But... the intro was so-so. I rated it a 11 out of 20. I would NOT recommend this for publishing at all.

I would not recommend for publishing because the conclusion was unclear, the methods could not be easily replicated but it was okay, the results could use expansion. The intro was good though!
