One carp, two carp: are there more carp in the Wailoa River?
The February, 2015 issue of Hawaii Fishing News included the annual list of Hawai`i records for the largest fish of various species caught in the state. Among the new records was one for a 15-pound grass carp (Ctenopharyngodon idella) caught by Avery Berido in the Wailoa River at Hilo on September 13, 2013. A photograph taken by Mr. Berido of the record grass carp garnered our attention because pictured fish looked quite similar to another Asian carp species, the black carp (Mylopharyngodon piceus). Mr. Berido informed us that he also captured a 10-pound grass carp from the same river in June, 2013. After close examination of all of the photographs provided by Mr. Berido, we concluded that both fish from the Wailoa River were unusually dark grass carp, not black carp.
