Seven weeks down, two more to go! Things have really turned up in intensity this week as deadlines for our projects are fast approaching. We’ve begun finalizing our data collection, and are well into analyzing our results to determine what we can from our data. So far, my results seem to indicate that while juvenile crabs can certainly be sustained on diets of either algae or sea urchin feces, these diets do not result in growth equivalent to the various meat treatments being tested. This is likely due to the protein and fat concentrations of the diets; we attempted to run nutrient analyses last week on the food types, but were unable to complete them. However, based on the results of the experiment so far, we can infer that algae and fecal pellets do not have the nutrient density to compete with meat in promoting growth in juvenile Dungeness crabs. This is evident in the fact that while almost all of the individuals from the clam, crab, and fish treatments have molted into their third instar, none of the crabs from the “vegetarian” diets have, despite appearing relatively healthy and active. Hopefully at least a few will molt in the next few days so that I can make some comparisons between the groups.
We took a group trip last weekend to Newport, OR to visit the Hatfield Marine Science Center, Oregon State University’s marine biology campus. We got a “backstage” tour of the center and surrounding labs, and we learned about the structure of the marine biology programs for students, current and past work conducted at HMSC, and plans for future projects and between HMSC and other organizations such as NOAA. The visitor’s center is awesome; along with touch pools, interactive exhibits, and featured fish and marine invertebrates, the center has exhibits on marine geology, fossils, and Oregon Coast history. Afterwards, we visited the Newport Aquarium, which was super fun but very busy. The drive to and from Newport was gorgeous; taking the Coastal Highway (101) is always exciting and full of amazing views.
This weekend was busier than last, as we are all trying to scramble to finish our projects and put together posters to present to the Coos Bay scientific community, which will occur in the final week here at OIMB. It’s been a whirlwind of a summer, and I’m excited to see the finished products of all of our work from the past two months!
Thanks for reading!
