In scientific research, larger sample sizes and more data points generally reduce the margin of error and increase the reliability and statistical power of the findings.

Scientific models are dynamic; they are continuously refined, updated, or replaced as new data, technology, and observations become available.

Maximum Sustainable Yield (MSY) is the largest average catch that can be captured from a stock under existing environmental conditions without depleting the population over the long term.

All of these types of biological and ecological data help fishers understand population dynamics, avoid catching breeding or juvenile fish, and target species at sustainable times and locations.

Scientific research provides critical data on fish populations, reproduction rates, and ecosystem health, which policy makers and fishers use to set sustainable catch limits and prevent overfishing.

Overfishing has cascading effects throughout the entire food web, impacting targeted fish species, non-target marine mammals through bycatch or food depletion, marine plants due to ecosystem imbalances, and humans who rely on fish for food and livelihoods.

Although humans live on land, we are deeply integrated into marine ecosystems through activities like fishing, trade, and pollution, making us an active part of the global marine food web and ecosystem.

Bycatch is defined as the incidental capture of non-target species, such as dolphins, turtles, seabirds, or unwanted fish, during commercial fishing operations.
