The Environment Agency’s National Coarse Fish Rearing Unit at Calverton, Nottinghamshire, has achieved a significant milestone by producing and stocking over 510,000 fish in 2024 to support national restocking efforts.
Record Fish Production at Calverton Unit
The Environment Agency’s National Coarse Fish Rearing Unit in Calverton, Nottinghamshire, has successfully produced and stocked 510,488 fish in 2024. This effort is part of the agency’s ongoing commitment to improving and restoring fish populations across the country.
The fish were stocked in various rivers and still waters identified through scientific surveys as needing a boost to their natural populations.
Targeted Restocking Strategy
The unit employs a science-based approach to ensure the fish are introduced into areas where they can make the most significant impact. This includes rivers affected by pollution and those with declining natural fish populations.
The strategy also involves stocking fish in still waters and supporting the development of new fisheries, particularly in areas with limited opportunities for young and disabled anglers.
Economic and Social Impact
The production and restocking of these fish have broader economic and social implications. By enhancing fish populations, the Environment Agency is supporting the angling industry, which contributes significantly to local economies.
Additionally, the improved water quality and restored fish populations benefit both recreational anglers and the environment as a whole.

Leadership Response
We are immensely proud of the work our team has done in producing and stocking these fish. Seeing the fish we produce helping to regenerate populations in rivers and still waters is incredibly rewarding.
Our approach ensures the best possible survival rates for the fish and makes a lasting difference to fish populations and angling for years to come.
Alan Henshaw, Team Leader for the fish farm at Calverton.
The quote highlights the dedication and scientific approach of the team at Calverton, which is crucial for the success of the restocking program.
Progress and Targets
- Average increase in fish weight of almost 40% due to lower stock densities
- Previous year’s stocking included approximately 400,000 fish across nine species
- Ongoing commitment to improving fish quality and survival rates
Local and Regional Impact
The restocking efforts have specific local and regional impacts. For example, the River Hull has been stocked with chub and barbel, showing considerable success in areas like Tickton and Weel.
Similar efforts have been made in other regions, including the stocking of grayling, dace, and chub in non-tidal areas.
Immediate Implications
The successful production and stocking of over half a million fish in 2024 will have immediate benefits for fish populations and the angling community.
This effort ensures healthier and more sustainable fish stocks, which is crucial for maintaining vibrant ecosystems and supporting recreational activities.
Broader Significance
The long-term significance of this initiative lies in its contribution to environmental conservation and the sustainability of fish populations.
By continuously improving restocking strategies and fish quality, the Environment Agency is working towards restoring and maintaining healthy fish populations, which is essential for both ecological balance and the economic well-being of communities dependent on these resources.
