Wild-caught fish are fish that are captured in their natural habitats, such as oceans, rivers, and lakes, rather than being raised in fish farms. This method of fishing can involve various techniques, including trawling, netting, and line fishing, and it aims to harvest fish populations that are abundant and sustainable. The benefits of wild-caught fish include a more natural diet and habitat, which can lead to better flavor and texture. However, concerns about overfishing and environmental impact have led to the promotion of sustainable fishing practices, ensuring that fish populations remain healthy for future generations.
