Sustainable harvesting aims to ensure that fish populations remain healthy and productive for future generations.

Fishing pressure is a human-induced factor that can affect species diversity, while habitat complexity, water temperature, and salinity are natural factors.

Bycatch refers to the incidental capture of non-target species, such as sea turtles or dolphins, in fishing gear.

Increasing fishing effort is not a method used to reduce bycatch, as it can lead to higher rates of non-target species capture.

Fisheries management involves the development and implementation of regulations and strategies to ensure the long-term sustainability of fish populations.

Habitat restoration is not a direct fisheries management tool, although it can contribute to the overall health of fish populations.

Stock assessment involves collecting and analyzing data on fish populations to estimate their abundance, biomass, and reproductive rates.

Overfishing can lead to reduced food security as fish stocks become depleted and less available for human consumption.

Ecosystem-based management considers the interactions between fish populations, their habitats, and other species in the ecosystem when making management decisions.

Setting fishing quotas based on maximum sustainable yield is not a principle of the precautionary approach, which emphasizes caution and flexibility in the face of uncertainty.

Catch and release involves returning fish to the water after they have been caught, often to reduce fishing mortality and protect vulnerable species.

MPAs are not designed to increase fishing efficiency but rather to protect marine ecosystems and promote sustainable fishing practices.

Artificial reefing involves deploying structures on the seafloor to create new habitats for fish and other marine life.

Effective enforcement of regulations is not typically a challenge in sustainable fisheries management, as most countries have well-established enforcement mechanisms in place.

Maximum sustainable yield management aims to set fishing quotas at a level that allows fish populations to replenish themselves while maintaining a sustainable harvest.
