Carcharhinus sealei is likely to be caught in relatively large quantities by artisanal fisheries and small scale commercial fisheries within its range, particularly in South East Asia, since it is most commonly found in shallow waters where such fishing activities are intensive. Short-lived (mature at one year and longevity five years), this species produces only one or two pups per year. Although recorded in Indonesia previously, this species was not recorded in a recent survey of markets within this region. There is concern that C. sealei may meet the Vulnerable criteria A2bd+3bd+4bd due to the high level of exploitation and its apparent population decline in some areas, but detailed species composition data are lacking and it is therefore considered Near Threatened.
|Range Description:||Carcharhinus sealei occurs off South Africa, Kenya, Madagascar, the Seychelles, Mauritius, southwest coast of India, Indonesia, Philippines, northern Australia and New Guinea (Compagno and Niem 1998).|

|Habitat and Ecology:||
Carcharhinus sealei is a coastal shark on the continental and insular shelves from the surf line to depths of 40 m, but usually in shallow water, not adjacent to river mouths (Compagno and Niem 1998).
C. sealei attains at least 95 cm total length (TL) and maturing at 70 to 80 cm TL. Viviparous with one or two young, born at 33 to 45 cm after a gestation of around nine months (Compagno and Niem 1998). The species feeds on small fish, prawns and squid. Van der Elst (1981) recorded age and growth data for this species, with age at maturity at approximately one year and maximum age of around five years.
|Major Threat(s):||Carcharhinus sealei is a common catch in artisanal fisheries and smallscale commercial fisheries, as well as by recreational anglers (Compagno and Niem 1998). This species occurs in shallow waters where fishing activities such as longlines and gill nets are often very intensive, e.g., in Indonesia, and therefore would be highly susceptible to overfishing. Although recorded in Indonesia previously, this species was not recorded in a recent survey of markets within this region (W. White, unpubl. data). The flesh is utilized for human consumption.|
|Conservation Actions:||Detailed species composition data from fisheries throughout its range are required in order to assess the actual level of exploitation.|
