Fish
Diagramma pictum ・ Haemulidae (Grunts)
Summer nights are the time. By day it shoals in the shadow of the rocks, but after dark it moves into surprisingly shallow water to feed. Of the big fish reachable with a surf rod, it is among the most accessible.
It makes sounds by grinding the teeth deep in its throat, and its swim bladder amplifies them. Nocturnal, it gathers in groups in the shade of rocks during the day. Found along the southern Pacific coast of Japan, around Okinawa and the Nansei Islands, in the East China Sea, and along the west coast of Kyushu.
Cast to the line where reef meets sand and leave the bait still. Thick, strongly scented baits such as iwaisome or spoon worm are the ones that work. A night take can knock the rod over, so fix the stand down, and light your feet before you move anywhere on dark rock.

A breakwater facing open water puts this fish within reach without going to the rocks. The two hours after sunset and the period before dawn are the windows, and the fish that come once it is light are said to be the bigger ones. Bites tend to fall around low water. Net it rather than lifting it.

This fish is dangerous to handle bare-handed.
Sharp spines
The dorsal spines are hard and sharp, and a big fish thrashing in the dark will drive one into your hand. Pin it with a towel or a fish grip before you touch the hook.
Dangerous fish and animals — what to do when you are stung or bitten
Sashimi, salt-grilled, or simmered. The thick skin is full of flavour and takes well to a quick blanching. Large fish are firm and satisfying.
Best eating: June–September
Check the local fishery regulation. Many rock marks and piers restrict entry or parking at night, so read the signage on site as well.
