The two most common questions about brown-marbled grouper are what it's called in English, and how it differs from longhu grouper. The English question has an easy trap to fall into — "tiger grouper" can refer to an entirely different fish in the English-speaking world, one found on the other side of the globe.
Identity: Its official Chinese name is 棕點石斑魚 (brown-marbled grouper), scientific name Epinephelus fuscoguttatus, Taiwan FDA ID J0405401. It is the mother species of the longhu grouper.
English name: FishBase lists its official name as brown-marbled grouper. Some people also call it tiger grouper, but that name is also used for a different genus of grouper in the western Atlantic — when researching, use the scientific name.

This common name is used for both the brown-marbled grouper (Epinephelus fuscoguttatus) and Mycteroperca tigris in the western Atlantic. The two belong to different genera and live in different waters.
English-language literature, FishBase, and WoRMS all index it under Epinephelus fuscoguttatus. Searching by scientific name won't lead you to the wrong fish.
Academic literature writes "hulong hybrid grouper," followed by a notation of the parent cross: E. fuscoguttatus ♀ × E. lanceolatus ♂.
棕點石斑魚 (brown-marbled grouper), Taiwan FDA ID J0405401. The mother species of the longhu grouper, less common in the market than the longhu grouper.
Its official name is 駝背鱸 (humpback grouper, Cromileptes altivelis) — a completely different species from the other two, and priced much higher. Its Chinese name differs from brown-marbled grouper's by just one character, making it the most common source of confusion.
A hybrid of brown-marbled grouper (mother) and giant grouper (father). Its official Taiwan FDA name is 龍虎石斑魚, ID J0405102 — the Chinese name takes one character from each parent.
Longhu grouper reaches market size in about a year and has strong disease resistance, making it the main farmed grouper species in Taiwan; brown-marbled grouper is farmed on a relatively small scale.
Crude protein per 100 g is 19.1 g versus 20.6 g, and crude fat is 3.7 g versus 3.8 g — the difference between the two is small. What's actually quite different is the father species, giant grouper, with 8.2 g of crude fat.
The advertiser on this page, YOUBAN (有斑), sells whole longhu grouper, not brown-marbled grouper itself. Buying longhu grouper means buying an offspring of brown-marbled grouper, but the two are not the same fish.
FishBase lists its official English name as brown-marbled grouper, scientific name Epinephelus fuscoguttatus. Some people also call it tiger grouper, but that common name is also used for Mycteroperca tigris in the western Atlantic — the two belong to different genera and live in different waters. For English-language research, the scientific name is more reliable than the common name.
No. Humpback grouper's official name is 駝背鱸 (Cromileptes altivelis), a completely different species from brown-marbled grouper (棕點石斑魚), and priced much higher. Their Chinese names differ by just one character, making this the most common mix-up.
According to the Taiwan FDA Food Nutrition Database, per 100 g, crude protein is 19.1 g for brown-marbled grouper versus 20.6 g for longhu grouper; crude fat is 3.7 g versus 3.8 g — the two are quite close. The clear outlier is the father species, giant grouper, with 8.2 g of crude fat.
