Fish Hatchery Monitoring
Biomark has designed antenna systems for hatcheries that monitor juvenile fish as they are released and adult fish as they return. Antenna systems at hatchery release locations provide accurate counts of fish leaving raceways or holding ponds. In addition, information about the exact release time can be used to determine true travel time from the hatchery to monitor sites downstream. Returning adult fish can be detected at fish ladders or traps at hatchery entrances.
Ringold Hatchery
Biomark designed, constructed and installed a pass-through antenna system for a fish trap at the exit of a 5-acre pond at Ringold Fish Hatchery on the Columbia River in Washington. The system was installed to detect and record the large volume of tagged fish that would pass during a four day scheduled release. The antenna system consisted of two weirs, each with four circular antennas. Each antenna was powered by a FS2001F-ISO reader.
Methow Hatchery
Biomark designed and installed this antenna to replace an existing raceway release pipe at Methow Hatchery in Washington.
Chewuch Hatchery
Biomark designed and installed these antennas to detect fish as they are released from an acclimation pond.
