Managing Oceanic Resources

Fisheries Management

Why are worldwide Fisheries in decline?

“Give a man a fish and feed him for a day teach him how to fish and feed him for a lifetime”

Major Concerns: - Habitat Loss - Pollution - Over Fishing

Fisheries Concerns: - pollution - habitats - larger boats - better SONAR - bigger gear - stronger gear

Air and Water Pollutants are major problems

Striped Bass

Fins often show problems

Biological Oxygen Demand “BOD”

Chemical Oxygen Demand “COD”

BOD + COD = TOD

Flounder

Stickleback

Biomagnification = pyramiding of pollutants

Point Source Control is important

National Marine Fisheries Service

Rosefish

Rosefish

Most fishing used to happen from shore or from “day boats” from local harbors

Good fisheries data is hard to get

Ray

Shark

Controls and Concerns can be: - Local - State - Regional - National - International

National Fisherman Magazine

Fisheries Management Councils

Fishermen tend to be very independent

Now huge factory ships stay at sea for weeks catching and processing catch

The inherent dangers in fishing at sea are great

Fishing efforts are not always productive

“Bycatch” continues to be a problem

Lost nets = “Floating curtains of death”

Lost traps keep on catching and killing resources

Maximum Sustainable Yield

Optimum Sustainable Yield

Fish are usually a nutritious inexpensive food source

Fish Protein Concentrate “FPC”

Fishing Regulations can be very effective

Sound fisheries management practices are vital

Fishing in the Global Pond

Safety at sea is still a major issue

Ecosystems Approach to Ocean Management

National Oceanographic and Atmospheric Administration

IFQ’s Individual Fisheries Quotas

Transferable Quotas are hotly debated

Alien Invaders Include: - Asian whelks - European crab - Asian swamp eel - Zebra mussel

HAACPP Hazard Analysis and Control Point Program

Aquaculture carefully done can be used as a partial solution to fisheries problems

Aquaculture

Sound Management of the Global Seas is a must
