Sparus macrocephalus, also known as black leather and sea squid, is distributed in four major sea areas in China, especially islands, rocks and ports.

It belongs to shallow-sea warm-bottom fish and likes to live in the sea area with rocks or sediment. Its sense of smell and hearing are sensitive and alert.

How deep does it hide in the water during the day? Except when the sea is turbid and the visibility under water is low, it rarely moves. At night, Sparus macrocephalus comes out to feed. It is very greedy and has a very diverse diet. It eats all edible things, whether it is plant bait or animal bait.

The best time for night fishing is moonless night, and the best time for fishing is dusk, before and after dawn and the daily tidal change period.
