|Scientific Name:||Chiloscyllium hasselti Bleeker, 1852|
|Taxonomic Notes:||The validity of this species needs to be further investigated. It is very similar to Chiloscyllium griseum and the two species are not well defined. Morphometric characters largely overlap each other and the main differences listed relate to colour of juveniles.|
|Red List Category & Criteria:||Near Threatened ver 3.1|

The Indonesian Bambooshark (Chiloscyllium hasselti) is a small, inshore, benthic shark known from Malaysia, Singapore, Myanmar, Thailand, Indonesia, Borneo and Vietnam. The reproductive and population biology of this species are poorly known. No specific data are available on catches or population trends, but it is regularly taken in fisheries throughout its range, and is likely to be threatened by population decline resulting from overfishing, destructive fishing practices and habitat modification, including the damage and destruction of coral reefs. Such threats are likely to increase in the future. As a result of these combined factors, this species is assessed as Near Threatened based on inferred continuing population declines approaching 30% in three generations (possibly ~27 years). There is a need for survey and appraisal of population trends and catch in fisheries.

|Population:||No information available. Rare in Indonesia, but more common in catches in Borneo.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Found close inshore to 12 m depth on sandy, muddy bottoms. This shark is 9-12 cm when born and grows to a maximum length of 61 cm TL (Compagno 2001). Males mature at 44-54 cm TL. Oviparous, with eggs hatching in about December (Compagno 2001).|
Taken in inshore fisheries off Singapore, Thailand, Indonesia and Borneo, and utilised for food. Likely to be threatened by overfishing, destructive fishing practices and habitat modification, including the damage and destruction of coral reefs throughout much of its range.
It is one of the ten most important shark species captured in Malaysian fisheries, using trawl gear, where it is consumed locally and also exported to markets in Hong Kong and Taiwan, Province of China (SEAFDEC 2006). It is also known to be captured, consumed and marketed in Thailand (SEAFDEC 2006). The flesh is marketed fresh for human consumption.
