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 management
Sustainable practice, education, & protecting vulnerable marine habitats
