What Can We Learn From 50 Years of Fishery Management?

United States ocean waters are home to diverse species of fish that feed families, anchor economies and draw millions of recreational anglers to the coasts year after year. Our fisheries support vibrant coastal communities and Indigenous cultures, while also sustaining a vast web of marine life, from the tiniest plankton to dolphins, sea turtles and whales.

Magnuson-Stevens Fishery Conservation and Management Act (MSA)

But fish populations are not inexhaustible. Overfishing has historically driven iconic fish populations like cod, red snapper and rockfish into serious decline or collapse. This is why in 1976, when faced with rapidly disappearing fish stocks that had once been abundant, Congress, scientists and fishermen worked together to establish a management system that would support fishing for the long term. This effort became the Magnuson-Stevens Fishery Conservation and Management Act, or MSA.

Fifty years have passed since the MSA was enacted into law, becoming the primary law governing the management of fisheries in U.S. federal ocean waters. Over time, through reauthorization and changes to implementation, the law has evolved to support a management system built on science and adapted to the distinct needs of each fishery and region. The law’s central goal is to prevent overfishing while achieving levels of fishing that provide the greatest overall benefit to the nation. This means managing fishing to keep fish populations healthy, abundant and productive for the long term.

What’s changed in the last 50 years

However, so much has changed for the ocean in the last 50 years, and new challenges are developing that will push our fisheries to their limits.

1. Failure to rebuild many overfished stocks: Overfishing, climate change and unsuccessful management approaches have left many fish stocks at low population sizes.
2. High demand from recreational fisheries: Despite the small-scale impact of each individual angler, millions of fishing trips and the many fish tossed overboard to die are adding up to big problems for our fish stocks.
3. Persistent bycatch: Progress has stalled on minimizing the unintentional catch of non-target fish and other wildlife, putting threatened species at risk and jeopardizing the income of small communities and the food security of Indigenous fishers.
4. Lack of investment in science, data and traditional knowledge: Aging systems, outmoded approaches and lack of scientific capacity are eroding our science-based management system, and new opportunities are being missed to upgrade our approaches and integrate traditional knowledge.
5. Habitat loss and ecosystem degradation: Coastal development, industrial activity, climate change and current fishing habits threaten fish habitats and marine ecosystems.
6. Changing ocean conditions and more frequent disasters: Fisheries management is not adapting fast enough as climate change causes fish stocks to shift their ranges and increases their vulnerability to stress, disease and collapse.
7. Economic vulnerability of fishing communities: Fishing-dependent communities face uncertain futures, cheap foreign imports and food insecurity.
8. Deregulation and poor governance: Conservation measures that have brought species back from the brink are being rolled back.

It’s clear that business as usual is not enough to guarantee abundant fish populations that can support coastal communities and fisheries. The future of fishing—and the health of our ocean—for the next five decades depends on tackling the challenges we face today.

The good news is that solutions are readily available. Ocean Conservancy experts have identified the most pressing problems and promising solutions to right this ship and make sure that everyone can fish for generations to come. With this information, governmental leaders can create smart policy, fishermen can consider new techniques, and we can all commit to valuing the protections that ensure there are plenty of fish, both in the sea and on our plates.
