Over the past three decades, there has been a general trend of declining fish catch worldwide. This decline is due to a combination of factors, including overfishing, habitat loss, climate change, and pollution. Many fish populations have been severely depleted, with some species nearing extinction. This has had significant impacts on both the environment and the economy. Fish are an important source of food and income for many people, particularly in developing countries. The decline in fish catch has led to increased food insecurity and poverty in many communities. It has also had negative impacts on the broader ecosystem, as fish play a critical role in maintaining healthy ocean ecosystems. Efforts are being made to address this issue, including implementing sustainable fishing practices, protecting critical habitats, and reducing pollution. However, more needs to be done to ensure the long-term viability of fish populations and the ecosystems that depend on them.
