The Longnose Hound Shark (Iago garricki) is a small shark (up to 75 cm total length) with a patchy distribution in the Indo-West Pacific. It has recently been recorded in new areas suggesting its range may be wider than presently known. Recorded from the continental slope at depths of 250–475 m. The species produces small litters of 4-5 young, but little else is known of its biology. It is taken in deepwater longline fisheries in Indonesia, but much of its Australian range receives little fishing effort. Despite being poorly known, this species is assessed as Least Concern based on a presumably secure status in Australian waters.

Habitat and Ecology [top]

Habitat and Ecology:The Longnose Hound Shark has been recorded in tropical waters on the continental slope at depths of 250–475 m (Last and Stevens 2009). Maximum size is at least 75 cm total length (TL); size at birth is about 25 cm TL and males mature at about 55 cm TL (Last and Stevens 2009). The species is viviparous with a yolk-sac placenta with litters of 4-5 young (Last and Stevens 2009).

Use and Trade [top]

Use and Trade: This shark is utilized for its meat and fins in Indonesia (White et al. 2006) and probably also in the Philippines.

Threats [top]

Major Threat(s): The Longnose Hound Shark is of minor interest to fisheries (Compagno 1998). It is taken in Indonesian small-scale deepwater demersal longline fisheries (White et al. 2006). It is likely to be taken as bycatch in the Australian Commonwealth managed North West Slope Trawl Fishery and the Western Deepwater Trawl Fishery which operate at depths of >200 m off northwest Western Australia. These fisheries are small with limited fishing effort (Marton and Mazur 2014a,b). Its area of occurrence off northeast Queensland overlaps with the Coral Sea Fishery; trawling there is limited (no trawl effort in recent years; Noriega et al. 2014) but this species may be a bycatch of line gear used in that fishery.

Conservation Actions [top]

Conservation Actions: Thee range of this species overlaps with some marine protected areas in Australia's Commonwealth Marine Reserve network, including the Coral Sea Commonwealth Marine Reserve.
