7.5.1 Sustainable Fisheries

Cards (47)

  • Fisheries are always sustainable regardless of management practices
    False
  • Order the following fishing methods from active to passive:
    1️⃣ Trawling
    2️⃣ Purse Seining
    3️⃣ Gill Netting
    4️⃣ Longlining
  • What is one consequence of overfishing on marine ecosystems?
    Disruption of ecological balance
  • Trawling is a fishing method that is highly selective and does not damage seafloor habitats
    False
  • Trawling is a non-selective fishing method that can damage seafloor habitats
  • Longlining is a fishing method that uses a long line with baited hooks
  • Fisheries are an important source of food and income globally, providing a sustainable source of protein
  • Common fishing methods include trawling, gill netting, longlining, and purse seining.
  • Overfishing occurs when fish are caught faster than they can reproduce
    True
  • Sustainable fisheries ensure that the catch does not exceed the maximum sustainable yield.
  • What is one sustainability consideration for purse seining as a fishing method?
    Can catch some bycatch
  • Gill netting is a highly selective fishing method that avoids bycatch completely.
    False
  • What is purse seining used to catch?
    A school of fish
  • Insufficient catch limits and monitoring can lead to illegal, unreported, and unregulated (IUU) fishing
  • Match sustainable fisheries with their characteristics:
    Catch does not exceed maximum sustainable yield ↔️ Depletion of fish stocks
    Use of selective fishing methods ↔️ Use of non-selective fishing methods
    Effective regulation and enforcement ↔️ Illegal, unreported, and unregulated (IUU) fishing
  • Sustainable fishing practices aim to maintain healthy fish populations and marine ecosystems over the long term.

    True
  • Non-selective fishing methods like trawling can damage marine habitats
  • Match aquaculture benefits with their descriptions:
    Controlled production ↔️ Helps prevent overfishing
    Selective breeding ↔️ Improves efficiency and sustainability
    Land-based or offshore systems ↔️ Reduces impact on marine habitats
  • Environmental challenges in aquaculture include disease transmission, pollution, and escapement of farmed species
  • Match sustainable and unsustainable fisheries with their characteristics:
    Catch does not exceed maximum sustainable yield ↔️ Overfishing leads to depletion of fish stocks
    Effective regulation and enforcement ↔️ Lack of regulation or illegal fishing
    Maintaining biodiversity ↔️ Damage to marine ecosystems
  • Selective fishing methods help avoid bycatch
  • Passive fishing methods rely on fish encountering stationary gear
  • What type of fishing method uses a wall of netting in the water?
    Gill netting
  • Active fishing methods involve moving the fishing gear through the water.

    True
  • Overfishing can lead to the collapse of fish species and ecosystem imbalances.

    True
  • Match the sustainable fishing practice with its effect:
    Catch limits ↔️ Prevent overfishing
    Selective fishing methods ↔️ Minimize bycatch
    Effective regulation ↔️ Enforce fishing rules
    Biodiversity maintenance ↔️ Balance marine ecosystems
  • Aquaculture is the farming of aquatic organisms and is emerging as a sustainable alternative to wild fisheries
  • Aquaculture faces environmental challenges such as disease transmission and pollution.
    True
  • International cooperation is necessary to enforce fishing regulations and protect marine ecosystems.

    True
  • Overfishing leads to the depletion of fish stocks because fish are caught faster than they can reproduce.

    True
  • What economic incentive drives overfishing in certain areas?
    High commercial value
  • Preventing overfishing is crucial for maintaining sustainable fisheries
  • What is the purpose of catch limits in sustainable fishing practices?
    To prevent overfishing
  • Implementing sustainable fishing practices is essential for protecting fishing communities and ensuring seafood availability.
    True
  • Aquaculture helps maintain fish stocks by allowing controlled production and harvest of seafood.

    True
  • Why are fisheries considered important globally?
    They provide food and income
  • Overfishing leads to the depletion of fish stocks because the catch exceeds the maximum sustainable yield.

    True
  • What are the two categories of fishing methods based on gear movement?
    Active and passive
  • Trawling is a highly selective fishing method that minimizes habitat damage.
    False
  • The sustainability of a fishing method depends on its selectivity, impact on habitats, and how well it is managed to prevent overfishing
