Source-derived summary

The Japanese sea bass (Lateolabrax japonicus) is a species of catadromous marine ray-finned fish from the Asian sea bass family Lateolabracidae. It is found in the Western Pacific.

Vernacular names

In the Kantō region and Shizuoka Prefecture, it is called seigo (セイゴ, 鮬) when under 25 cm (9.8 in) in length. At 3 years of age, when it has attained a length of nearly 60 cm (24 in), the name changes to fukko (フッコ) or suzuki (スズキ, 鱸). In the Kansai region, it is called seigo, hane (ハネ) or suzuki, and other regions may have names for this fish different from the ones just listed.

In China, this fish is commonly called 花鲈 (traditional Chinese: 花鱸).

Description

The Japanese sea bass has a slightly forked tail and a large mouth, with the lower jaw protruding beyond the upper jaw. Younger fish have small black spots on the back and dorsal fin; these tend to be lost in larger fish. The first dorsal fin has 12-15 spines; this is followed by 12-14 soft rays in the second dorsal fin. The anal fin has 3 spines and 7 to 9 soft rays.

Editorial summary

The public source identifies “Japanese sea bass” as species of fish. This brief keeps that definition visible, then builds a research path around Japanese, bass and species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current 190-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Japanese, bass and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Japanese sea bass”, the useful work is to connect “species of fish” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 9, 2026. The linked authority identifier is Q1151311. None of the 0 selected statements returned an explicit reference.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
