Trophic Strategy

Occurs inshore (Ref. 75154). Inhabits coral reefs, including sheltered lagoons and outer reefs (Ref. 30573, 58652). Enters lake (Ref. 13446). Usually found singly, often adjacent to steep outer reef slopes, but occasionally found in groups (Ref. 9710). Feeds mainly on fishes, but also takes shrimps, crabs, amphipods, stomatopods, gastropods and urochordates. Large fish from oceanic areas in the western Pacific are often ciguatoxic, e.g., in Tuvalu (Ref. 9513).

利用

許多沿岸國家重要之食用魚。主要漁法為一支釣及底部延繩釣為主。一般以煎食或紅燒為食。唯大型魚因食物鏈之故,內臟可能累積熱帶海魚毒,在國外有食物中毒之例。

Lutjanus bohar

Lutjanus bohar, the two-spot red snapper, the red bass, twinspot snapper or bohar snapper, is a species of marine ray-finned fish, a snapper belonging to the family Lutjanidae. It has a wide Indo-Pacific distribution.
Taxonomy
Lutjanus bohar was first formally described as Sciaena bohar in 1775 with no type locality given, although it is thought to be the Red Sea.[3] The description is attributed to the Finnish-born Swedish explorer Peter Forsskål by FishBase,[2] but the Catalog of Fishes attributes as follows
“Fabricius [J. C.] in Niebuhr (ex Forsskål) 1775:46, xi [Descriptiones animalium (Forsskål)”
Catalog of Fishes then states that the valid binomial is Lutjanus bohar (Fabricius, 1775).[3]
The specific name bohar is the Arabic word used for this fish in the Red Sea.[4]
Description
The two-spot red snapper can reach a length of 90 cm (35 in), though most do not exceed 76 cm (30 in). The greatest recorded weight for this species is 12.5 kg (28 lb). These large reddish tropical snappers show darker fins, a rounded profile of head and a groove running from the nostrils to the eyes. They have 10 dorsal spines and 3 anal spines. Juveniles and some adults have two silvery-white spots (hence the common name) on the back close to their dorsal fins, while larger adults lose the spots and become mostly red.[5] Large adults may cause ciguatera poisoning.[5]
This species is a commercially important species[1] and is also sought-after as a game fish.[6]
Biology
It is a long-lived and slow-growing species which reaches maturity at 8–9 years, and the oldest recorded individual is 56.[5] These fishes are carnivorous, mostly feeding on other fishes, crustaceans and molluscs.[5]
Adult snappers often form large schools on the outer reefs or above sandy areas, mainly to form spawning aggregations. Small brownish juveniles mimic damselfishes of the genus Chromis in order to approach their prey.[5]
The chambered nautilus, Nautilus pompilius, is known to scavenge deceased snappers. A pair of nautiluses recorded feeding on a snapper at 703 metres below the surface constitutes the deepest recorded sighting of any nautilus species.[7]
Distribution
This species is native to the Indian Ocean. It is widespread in the Indo-Pacific from the east African coast, north to the Red Sea, to the western Pacific Ocean, north to the Ryukyu Islands, south to Australia.
Habitat
It is a coral reef inhabitant, being found at depths from 4 to 180 m (13 to 591 ft), though usually between 10 and 70 m (33 and 230 ft).[5]

Inhabits coral reefs, including sheltered lagoons and outer reefs. Usually found solitarily, often adjacent to steep outer reef slopes.

Large fish from oceanic areas in the western Pacific are often ciguatoxic, e.g. in Tuvalu (Ref. 9513). Utilized fresh and dried-salted (Re. 9987). Reported to grow up 90 cm in length (Ref. 9987). The young have been repported to mimic certain damselfishes of the genus Chromis, such as C. ternatensis (Bleeker) and thereby get closer to their prey .
