Week 6: Conservation


Monday, May 5th:

This week was all about Marine Conservation and Policy! We met our instructor Sarah Henkel at 9:00am. This first day we learned about the oceans, climate change, oceanic resources such as tidal and wave energy, and aquaculture. The day consisted of lectures and deciding upon our conservation/policy research topics. 


Tuesday, May 6th:

In lecture, we learned about marine reserves and their ecological importance, and the struggles of regulation within marine reserves. 

Marine Reserves (MR), essentially are preservation lands prohibiting all commercial and recreational uses as well as oceanic development where as Marine Protected Areas (MPA) are regulated commercial and recreational areas but also prohibit oceanic development. 
MRs and MPAs are most commonly adjacent to one another; Cape Perpetua is a fine example.

When the sun began to set, in a large room in the Guin Library, a group of 22 students and their instructor, loudly speculated their ideas of science, policy, and ethics and their connectivity within the life of a scientist. What an eye-opening discussion it was!

Wednesday, May 7th:
This was one of the most exciting days of the week! We had a dock walk with Laura Anderson, owner of Local Ocean Seafoods in business for over a decade now, where she talked to us about fishing and where her fish and crustaceans came from. 

One of the boats she buys fish from, uses glazing as a means of keeping fish "fresh." Glazing flash freezes caught fish, leaving them in the same conditions they were in when first caught for longer preservation time.




Check out this neat tuna fishing boat! Laura pointed out to us certain key features that can help distinguish what type of catch this boat fishes. 

Having a cover for the tuna is essential in reducing diseases by decreasing the beat of the sun, avoiding the rise in temperature of their bodies.









These wooden doors are features found on a pink shrimp boat.
The doors have good buoyancy and help the net to stay open. 









After our lovely dock walk with Laura, we had lunch at Local Ocean Seafoods. Food choices ranged from fish wraps and salmon salads, to crab cakes and Albacore tuna kabobs. 




 Fish and crabs were displayed upon entrance in a case full of ice with the name of the boat from which they were caught. Thumbs up for them!

Thursday, May 8th:

We had another exciting field trip to Cape Perpetua and Ten-Mile Creek. 

Paul Engelmeyer, a conservation advocate, discussed his work in MRs and MPAs and his 1000 acre land protection project. He also talked about the watershed councils all around Oregon and the health of the water. Looking at one of his maps, our water systems aren't doing so well.


We then piled back into the warmth of the dry vans and headed to Ten-Mile Creek to meet Chris Lorion, Oregon Dept. of Fish and Wildlife, and Jack Sleeper, fish biologist. 

Chris Lorion showed us the neat fish collecting trap that allows him to record data on the fish abundance and diversity in the river. 






This is the fish trap used by ODFW. Fish are directed into the trap and taken out for recording fish dynamics every day.









One of the fish caught on this day was the Pacific lamprey, Entosphenus tridentatus. These adult female lamprey recently laid their eggs. 

We had the opportunity of holding them. Look at that smiling face!




In the open forest, Jack Sleeper talked to us about the importance of fallen trees in the river to steady water flow and for creating a complex habitat for fish. He also noted the seriousness of not having roads impede accessible waterways for fish, such as culverts do. 





This fallen tree is vital for juvenile salmon populations as a means of protection from predators and fast flowing waters. 







Friday, May 9th:
Presentations! One right after the other. Eleven presentations, all concerning different topics about the oceans. Our topics included ocean acidification, arctic ice caps melting, hypoxia, marine mammal containment, coral reefs, artificial reefs, seafood labelling, invasive species, Bluefin tuna migration, and fish hatcheries. Each group had a specific target audience, varying from the general public to policy-makers. Every topic had something interesting to say, capturing our attention. Needless to say, we all learned something new from each issue.

Our First Trip North




After delicious pie Tuesday night and some good old fashioned bonding, we started discussing the inverts Wednesday morning. After learning about the phyla Porifera, Cnidaria, and Ctenophora, we entered the laboratory for the first time. Here we cleaned and set up the tanks for organisms collected from our first two excursions. 

Our first stop yesterday afternoon was the Newport docks. The sun was out as we lay down on the docks to discover and capture some of the invertebrates that live beneath the wood. After the docks, we loaded our new friends into our vans and made our way to Boiler Bay. Even though the tide was not extremely low (only 0.11m) we were able to collect sea stars, chitons, urchins, crabs, limpets (like the keyhole limpet on the left), and many other invertebrates. Luckily, the clouds didn’t open until we were back in the vans heading to Newport to place the organisms in the laboratory tanks for observation and sketching.

This Week in HMSC: Guests Lectures, Confused Fishermen, and Cramming for a Test

Oh snap! The second week of BI 450 is passing us in a flash and it’s been great!

The week started out with two very informed guest lectures. First was an in depth look at the mechanisms of invasive species from Dr. John Chapman, focusing on Yaquina Bay’s own mud shrimp, Upogebia pugenttensis, and its quite damaging isopod parasite Orthione griffensis, a relationship we saw first hand last week while visiting Sally’s Bend. Then we had a talk from Dr. Sylvia Yamada, a specialist on the invasive European Green Crab. Sylvia took us down to the shore of HMSC to take data on the crabs she caught so we could get an idea of how diverse the range of species is in our backyard. Much pinching of fingers ensued.





Tuesday was an adventure out at the boat yard where we diligently searched the waters for any signs of life. Mostly we just confused the fishermen. But we did not go away empty handed! We found an abundance of Polyorchis penicillatus, commonly named red-eyed medusa, along with a ctenophore, Pleurobrachia bachei, also known as a sea gooseberry. A quick break for ice cream was a well deserved reward.




Wednesday came with a mad rush to finish our Favorite Invertebrate projects. There was dancing and games, lots of food and an odd new drug craze involving some unfortunate anemones and interviewees. It was a wonderful break from our diligent studying, but now it is time to get back to the grind and finish those darn notebooks!
