長野県水産試験場

The Nagano Prefectural Fisheries Experimental Station is a research center in Azumino focused on fish farming, aquatic ecology, and sustainable management of water resources. The facility studies the impact of introduced species on native fish populations and conducts regular monitoring programs.

The facility was established in 1984 with a focus on monitoring and protecting native fish species. Over the decades, the station has expanded its work to study the ecological consequences of invasive species in local waters.

The station collaborates with schools and universities to offer learning programs about fish biology and water conservation. Visitors can observe how the facility engages the local community in protecting the region's aquatic resources.

The facility conducts annual fish release programs and applies strict disinfection protocols for fishing equipment to protect local waters. Visitors should be aware that access and tours may be limited and should be arranged in advance.

Researchers at this station have documented distinctive features in crayfish populations that set them apart from other Japanese regions. These findings have implications for understanding regional aquatic biology and species characteristics.
