Similarly, the luxury yacht industry, valued at approximately $4.8 billion globally, supports fishing tourism and high-end recreational fishing, illustrating the economic breadth beyond commercial harvests.

a. Overfishing and its effects on marine ecosystems

Overfishing reduces fish populations faster than they can replenish, leading to stock collapses. For example, the North Atlantic cod fishery declined dramatically in the 1990s due to excessive catches, causing ecological imbalance and economic hardship. Scientific models estimate that overfishing can result in the loss of up to 80% of target stocks if unregulated.

b. Bycatch and unintended species harm

Bycatch refers to non-target species caught unintentionally, including seabirds, turtles, and juvenile fish. Large-scale fishing methods like trawling are notorious for high bycatch rates. For instance, shrimp trawling can result in bycatch ratios of up to 20:1, harming biodiversity and disrupting food webs.

c. The importance of sustainable practices and regulations

International agreements such as the UN Fish Stocks Agreement and regional fisheries management organizations (RFMOs) aim to regulate catches and protect vulnerable species. Adoption of selective gear, closed seasons, and marine protected areas are scientific strategies to mitigate ecological harm, ensuring long-term resource availability.
