The Ohio Division of Wildlife announced that two longhead darters had been caught in the Ohio River last fall. This species was last spotted in Ohio in 1939.
それ以来, the species was considered extirpated from the 状態.
The recent discovery, しかしながら, suggests that there is still a population of longhead darters in the state, even if it is very small. It’s unclear if the species has returned to the area or if a small population was able to go unnoticed for the last several decades.
The Ohio DOW posted about the find on Facebook, 書き込み, “Why are we so excited? This striking creature, native to Ohio, was thought to be extirpated from the state… that is until fish management crews captured two this fall during Ohio River electrofishing bass surveys.”
投稿は続きました, “These were the first captures in Ohio since 1939 when Milton B. Trautman captured seven in the Walhonding River, a principal tributary of the Muskingum River in east-central Ohio.”
The Ohio DOW also offered an explanation for the term “extirpated,” 書き込み, “The term refers to species that are locally extinct but not gone completely from the planet. Fortunately for the longhead darter and for those of us concerned, this species is not extirpated in the Buckeye State.”
