Lutjanus johnii, Bloch 1792
Not evaluated
Harmless
A round black spot, larger than eye, on back, mainly above lateral line, below anterior soft dorsal rays (sometimes absent in large adults).
All East African records for this species could be misidentifications of L. ehrenbergii, a species it closely resembles and been confused with (Bock, 1996).
Generally yellow with a bronze to silvery sheen, shading to silvery white on belly and underside of the head. A large black blotch mainly above the lateral line below the anterior dorsal-fin rays. Dorsal profile of head steeply sloped. Preorbital width equal to eye diameter or larger. Preopercular notch and knob poorly developed. Scale rows on back parallel to lateral line. Center of each scale often with a reddish-brown spot, giving an overall appearance of series of horizontal lines on side of body. Dorsal spines (total): 10, Dorsal soft rays (total): 13 - 14, Anal spines: 3, Anal soft rays: 8
Maximum total length about 70 cm; common to 50 cm.
Pseudomonas alcaligenes, Cucullanus vishakhapatnamensis, Zeylanicobdella arugamensis
Indo-West Pacific: East Africa to Fiji, north to the Ryukyu Islands, south to Australia.
Reef associated, rocks, deep sea, estuarine, some times in lower reaches of freshwater streams
Spawning has been reported during September in the Andaman Sea.
Tertiary consumer.
A nematod species, Cucullanus vishakhapatnamensis was reported from intestine of L. johnii caught at Vishakhapatnam, East coast of India (Bharatalakshmmi, 1999). Metazoan fish parasite were reported from Inodnesia population such as larval Anisakis sp. were isolated from stomach wall of L. johnii. A nematod Procamallanus sp. was found in intestinal content of L. johnii. A Annelis species Zeylanicobdella arugamensis De Silva, 1963, reported from L. johnii (Rueckert et al., 2009). Hemorrhagic septicemia caused by Pseudomonas alcaligenes in L. johnii was reported from India (Pillai and Freitas, 1984)
Flesh quality is excellent. Consume in fresh as well as salt dried.
