Introduction to Bottom Trawling• Hidden beneath the surface of the ocean is a world waiting

to be explored• 500,000 and 5,000,000 marine species are yet to be

discovered• What are some ways to reduce fisheries bycatch &

discard from the resulting practice of bottom trawling in California?

Early History of Bottom Trawling• 1376- petition required the prohibition of a

wondyrchoum• 19th Century- There should be no regulation/limitations

on Bottom Trawling

Current Regulations• Limited Entry• Trip Limits• Size Limits

• Seasons

• Gear Restrictions• Closed Areas

Who’s At Stake?• Environmentalist• Fishermen• Tourists

General Approaches• Encourage good fisheries managementSustainable practice, education, &

protecting vulnerable marine habitats

Fisheries management required to

incorporate ecological aspect (+) Reduce threats to life (+) Ensure long-term health, integrity &

adaptability of ecosystems (+) Protection & preservation (+) Limit overfishing (+)

Reduce high ratio

of fuel spent per

ton of fish landed

(+) Less boats (+) Reduce protein

energy < fuel

energy (+)

Alleviate competition (+) Put some fishermen out of a

job (-) Promote tourism (+) Possible increase on amount

spent for seafood (-)

Bottom

trawling ban

Marine habitats can recover (+) Reestablish species growth (+) Vulnerable species not caught (+) Destruction to ocean reduced (+)

Less boats (+) Ensure sustainable

fish community (+) Less fishermen (-)

Moral values on coastal

communities (+) Encourage diversity (+) Loss of jobs (-)

Recommendation• Implement Sustainably Managed Bottom Trawling Rights!• Limitations: Sustainable Fishing Rights• Concession: Ban = Loss of Jobs for Fishermen• Consequence: Result in Illegal Fishing Practices
