APES: 5.8 & 5.16 - Overfishing and Aquaculture

Front

What are marine reserves?

Back

Protected areas of the ocean where all harvesting of marine organisms is illegal to conserve biodiversity and replenish fish stocks.

Front

What is maximum sustainable yield (MSY)?

Back

The largest yield (or catch) that can be taken from a specific fish stock over an indefinite period under constant environmental conditions without causing the stock to collapse.

Front

What is bycatch?

Back

The unintentional capture of non-target species while fishing, which can lead to population declines of those species.

Front

What are the environmental impacts of aquaculture?

Back

Aquaculture can lead to contamination from fish waste, habitat destruction, and the introduction of non-native species.

Front

What is the purpose of the Seafood Watch program?

Back

To provide consumers with information on sustainable seafood choices and to promote responsible fishing practices.

Front

What is trawling?

Back

A fishing method that involves dragging a net along the sea floor to catch fish, often resulting in high bycatch.

Front

What are non-native species?

Back

Species that are introduced to an ecosystem where they do not naturally occur, which can disrupt local ecosystems.

Front

What is the consequence of breeding non-native species with wild populations?

Back

It can lead to genetic dilution and negatively impact the genetic diversity of native species.

Front

What is the role of fish waste in aquaculture?

Back

Fish waste can contaminate water and lead to nutrient pollution, affecting local ecosystems.

Front

What is pole fishing?

Back

A fishing method that uses a single fishing pole and line to catch fish, typically resulting in lower bycatch.
