Lecture 1:

Recreational Fisheries:

  • Choice in keeping or releasing fish
  • Like commercial Fisheries
  • Want to establish a sustainable harvest
  • Changes in habitat, remote location, gears, human activity (Anglers)
  • Stocking of fish exists
  • Used to enhance population and introduce new species
  • Popular for sport fishing
  • 1900’s, heavy angler population drove an overall decline in fish populations
  • 1980’s, catch and release practice became popular
  • New management, promoted sustainability

Bycatch:

  • Trawly net
  • Net comes up and are counted
  • Catch would include fish that we did not want
  • Decreases survivability of juveniles and adult fish caught
  • Foundation of sustainability -> catch and release and selective harvest
  • Currently, focus on sustainable resource
  • Many recreational Fisheries is sustainable
  • Unsustainable = not directly linked to recreational fisheries
  • Angler effect conservation and ecosystem
  • Influence many aspects of Fisheries industry
  • Cycle of money goes in to help Fisheries
  • Class program for Fisheries
  • Promote Fisheries knowledge and early exposure to field

Lecture 2:

Commercial Fisheries:

  • Regulation on number of harvest per season
  • Aquaculture should be built away from wild population
  • Helps prevent hybridization of poor fitness fish
  • Reduction in fleet size and destructive technology/ equipment
  • Increase in scientific research and methods to help introduce new aquaculture methods
  • Want to decrease selective pressure for size

Seafood labels:

  • How to read/ educate self on sustainable fish products
  • Information on product and markers of APPROVED products by FDA

Marine Protected Areas (MPA)

  • Increase to 10-30% of ALL OCEANS
  • Protect species and habitat along with biodiversity
  • Increase funding for programs and research

Aquaculture:

  • Open cage culture vs inland recirculating system
  • Effects wild populations
  • New technology/ research
  • Large amount of change/ replacement of commercial harvest
  • Use of renewable energy/ resource
  • Decrease use of dry feed/ fish feeds

Recreational Fisheries:

  • Expected to increase in popularity in the future
  • Increase habitat restoration (Dam removal)
  • Has increased sustainability
  • Educate youth for future
  • Money from people/ community are cycled back into programs to help promote sustainability
  • Replace commercial/ inland fisheries
  • Greater economic impact in Recreational Fisheries!

Hatcheries and Stocking:

  • Decrease change in enhancing fish population
  • Want to increase change in introduction of fish

Today, the greatest threat to Fisheries is:

  1. Habitat loss and degradation
  2. Invasive species
  3. Loss of biodiversity

Climate change
