FISHERY BULLETIN: VOL. 82, NO. 4 



Interest to fisheries. — The fishery for this species 

 was begun in Daidoko, Korea, by Japanese fisher- 

 men in 1917; it is caught in summer and autumn 

 with drift nets and pound nets (Kishinouye 1923). 

 It is usually not distinguished from other species 

 of seerfishes but comprises an important part of 

 the drift net fishery in Palk Bay and the Gulf 

 of Mannar between southeastern India and Sri 

 Lanka (Devaraj 1976). 



Distribution. — Continental Indo-West Pacific 

 from Japan, Korea, and China south to Singapore 

 and Sumatra and west to Bombay, India (Fig. 55). 

 The northern limit of the range is Wakasa Bay in 

 the Sea of Japan (Nakamura and Nakamura 

 1982). This species usually does not occur north of 

 the west and south coasts of Korea (Kishinouye 

 1923). Specimens obtained in the Tokyo markets 

 apparently are usually imported from Korea 

 (Okada 1955). There are museum specimens from 

 Ningpo (MNHN 5513), Swatow, and Hong Kong 

 (BMNH 1939.1.17.48) along the coast of China. 

 There appear to be few specimens or records from 

 the coast of Indochina or the Gulf of Thailand, but 

 we have examined specimens from "Cochinchine" 

 (MNHN A.6827). There are several reports and spec- 

 imens from Sumatra (Bagan Api Api, Hardenberg 

 1931 as Cybium kuhlii; Delsman and Hardenberg 

 1934 as S. guttatus; ZMA 114.593), but the range 

 apparently does not extend out further into the 

 East Indies. Dependable Indian records are from 

 Pondicherry (USNM 216698), Palk Bay, and the 

 Gulf of Mannar (Devaraj 1976) on the east coast, 

 and Bombay (ANSP 88360) on the west coast. 



Geographic variation. — Morphometric data were 

 compared by ANCOVA for three small samples of 



S. koreanus: India (n = 5), East Indies (n = 9), 

 and Japan and China (n = 8-12). Null hypotheses 

 that the 3 sets of regression lines are coincident 

 were accepted for 25 sets, rejected only for body 

 width. The Newman-Keuls Multiple Range Test 

 showed that the population from Japan and Chi- 

 na differed significantly in slope from that in 

 the East Indies. The population in the East Indies 

 did not differ significantly from that in India so 

 these two populations were combined and retested. 

 The only significant difference was again maxi- 

 mum body width and the combined India-East 

 Indies population differed significantly from the 

 Japan-China population (slopes 0.090, 0.123, Q = 

 5.987**). No meristic differences were found be- 

 tween populations.
