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!

A plate of fish tacos marinated in a chili-garlic sauce. YUM!

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.

Two students presenting their research on marine mammal containment as if their audience were the general public. Great job ladies!
