I saw a kurodai in the Sumida River
It seems that there are various creatures in the Sumida River. For the first time, I was able to see crodi.
During the walk, a large black fish shadow was on the river surface. What is this fish?
Despite the early morning, I was walking with my dog near the gates of the Kamejima River in the river’s edge of the Sumida River, which is already hot, and found something like dorsal fin on the water surface near the shore. If you look closely, it looks like a pretty big fish. It feels like an up-up because it's hot. I set up my phone because it was rare.
If you look at it, it looks like a blackfish.
When I go back and check it out, it looks like a crodi. In Kansai, it is called Chinu. Another day, it was discovered near Tsukuda-ohashi Bridge. This time, 4 or 5 fish seemed to be chasing a flock of small fish. As I first saw it, Kurodai inhabits a lot of brackish waters and shallow waters, and it is said that it has long been a major fish in the back of Tokyo Bay and the Sumida River. In Rohan Kouda's novel, there is a novel called "Jundan" set in Sumida River and Kurodai fishing in front of Edo. The Sumida River has become much cleaner, the food such as crabs has become abundant, and the fish seems to be returning. Blackfish fishing on the Sumida River seems to be a topic in the net, and recently I often see anglers fishing on the shore, and have a large net for goby fishing, and I wondered what it was, but it was aimed at blackfish. I've solved the question.
