MS1

- Sustainable fishing: practices that ensure the long-term health and productivity of fish stocks (1)

- Importance:

- Preserves fish populations for future generations (1)

- Maintains marine ecosystems and biodiversity (1)

MS2

- Two methods:

- Quotas: limits on the amount of fish caught (1)

- Closed seasons: periods when fishing is prohibited (1)

- Marine protected areas (MPA): areas where fishing is restricted or banned (1)

MS3

- Overfishing reduces the abundance of target species (1)

- This creates niche opportunities for other species, leading to their proliferation (1)

- Loss of key species can disrupt ecosystem balance, causing other species to decline (1)

- Reduced prey availability can affect higher trophic levels, cascading through the ecosystem (1)

MS4

- Advantage: increased catch efficiency (1)

- Disadvantage: possible overfishing/bycatch (1)

MS5

- Aquaculture: farming of aquatic organisms (1)

- Reduces pressure on wild fish populations by providing an alternative food source (1)

- Can be used to restore depleted stocks through hatchery programs (1)

- Overfishing: catching more fish than MSY, leading to stock depletion (1)

MS7

- Fish restocking: releasing captive-bred fish into natural waters (1)

- Used to:

- Replenish depleted stocks (1)

- Maintain genetic diversity (1)

MS8

- Initial increase in population size due to underfishing (1)

- Decline in population size as fishing pressure increases (1)

- Population reaches a critical point where overfishing occurs (1)

MS9

- Buying fish from sustainable sources (1)

- Choosing fish with eco-labels (1)

- Reducing seafood consumption (1)

MS10

- Fish stocks often cross international boundaries (1)

- Cooperation ensures coordinated management plans (1)

- Prevents overfishing and promotes resource sharing (1)

- Protects migratory species and maintains healthy ecosystems (1)
