Fisheries Resource Ecology Lab
Machine-translated · View original
A lab that explores how fisheries resources work by studying the lives of coastal fish and shellfish.
AboutAbout the lab
Understanding the workings of nature in order to use biological resources sustainably
The Fisheries Resource Ecology Lab studies the ways of life of fish, shellfish, crustaceans, and other organisms living in the ocean, rivers, and lakes.
In addition to their feeding, growth, and reproduction, the lab examines relationships among organisms and with their environment, aiming to understand how nature works.
The lab believes that understanding how nature works is the foundation for continuing to use biological resources, an essential source of food for people, sustainably into the future.
Key terms
- Environmental DNA
- DNA derived from organisms that is contained in the environment. It is used to investigate the distribution and abundance of the organisms living there
- Nursery ground
- A place where fish and shellfish grow up when young. Estuaries, tidal flats, and seagrass and algal beds serve this role
- Primary production
- The creation of organic matter through photosynthesis by phytoplankton and other organisms. It forms the base of the food supply in an ecosystem
ResearchResearch themes
The lab studies the relationship between the lives of fish, shellfish, and other organisms living in the ocean, rivers, and lakes and their environment, with the aim of clarifying the patterns of fluctuation in fisheries resources and their causes. It also works on estimating the distribution and standing stock of coastal resources through surveys using environmental DNA.
*Illustrative imageFluctuations in coastal fish and shellfish resources
For Japan's coastal resources, the lab clarifies resource ecology across the entire life history and carries out stock analysis. Through this, it clarifies the patterns of resource fluctuation and their causes.
*Illustrative imageFactors that determine coastal fisheries production
Coastal fisheries are those in which diverse fisheries use diverse resources and support fishing communities. The lab clarifies the various factors that determine their production.
*Illustrative imageMechanisms of biological production in coastal areas
The lab investigates the mechanisms of primary production in coastal areas that support coastal fisheries. In particular, it aims to clarify how phytoplankton and benthic microalgae contribute to the biological production of fish, bivalves, and other organisms.
*Illustrative imageDeveloping methods to evaluate nursery grounds
Estuarine brackish areas, tidal flats, seagrass and algal beds, and shallow sandy coastal waters are production grounds for sand-burrowing bivalves and nursery grounds for fish. The lab develops methods to clarify their importance based on biological production in these habitats, the distribution, growth, and survival of individuals, and their contribution at the population level.
