The present invention relates to a fishway barrier block installed in a river to make up a barrier within a fishway. The purpose of the present invention is to allow fishes to easily swim upstream as the fishway barrier blocks are fixated to a concrete floor of a fishway structure in a lateral direction by a fixating device at the bottom of the fishway barrier blocks to make up the fishway barrier provided in a pool within a fishway in order to reduce the flow rate; and to allow fishes to smoothly swim upstream as the fishway barrier blocks are made by attaching the fixating device to the bottom of a native rock to make up the fishway barrier in order to provide a natural environment for fishes. The fishway made up by the fishway barrier blocks secures a certain water depth against the low-water level of the river using the blocks to allow fishes or other organisms to freely flow and the river to be connected to the fishway in order to restore a river ecosystem; prevents the loss of the fishway barrier blocks as the fixating device securely fixates the fishway barrier blocks; reduces the construction cost of the fishway without the placement of mortar for fixating the fishway barrier blocks; and provides a natural environment when the fishway barrier blocks are made of a native rock. In addition to this, the fishway barrier block made of a native rock is applied to the construction of a barrier for preventing the loss of a riverbed or a river bank to be securely fixated by the fixating device, thereby preventing the loss of the blocks and the scour of the riverbed of the river bank.
