The Fisheries Cooperative Associations Women's Group Council in Hokkaido is proceeding with "tree planting activities to increase fish".
Hokkaido, blessed with abundant marine resources and surrounded by an abundant sea, is blessed with many sea resources such as salmon, scallop, and kombu kelp.
 Salmon fishing is carried out all over Hokkaido. The birthplace of salmon is naturally abundant rivers. |
 Scallops are produced via sowing and cultivating. The nourishment for plankton, which is the bait for scallops, is provided from the land to the sea. |
 Kombu grows large through nourishment provided from the forests through the rivers. |
Increasing resource cultivation
Fishing work is not only fishing. In order to protect abundant resources, a variety of increased cultivation operations are carried out. These operations require nutrition-rich and clean rivers and seas.
 Salmon, which swim upstream, are captured in capture locations. There are also rivers where they naturally spawn. |
 Eggs harvested from captured salmon are incubated through the winter in clean water. |
 Fry which have grown large set off down the river for the sea in spring. |
Support the sea's nourishment
A variety of nourishment is provided to the sea from the forests through the rivers. It has recently been found that fallen leaves which flow from the forests are directly connected to the nourishment of the seas.
 Righteye flounders gather where fallen leaves which have flowed from the river to the sea build up. |
 Within the stomachs of righteye flounders are found the gammaridean amphipods which had been eating the fallen leaves in the sea. |
 Sea urchins also flock to fallen leaves in the sea. |
