Sustainability overview

Threadfin bream is one of the most commercially important species in the Gulf of Thailand. Its stock status is classified as fully fished. It is a demersal species and part of a straddling stock and therefore of potential interest to fishermen, both licenced and unlicened, operating on the high seas and in national waters. Fishng effort on this species is too high.


The family Nemipteridae belongs to the Class Actinopterygii (ray-finned fishes) and the Order Perciformes. Occurs on mud or sand bottoms. Most abundant in depths of 20 to 50 m. Feeds mainly on small shrimps, squid, small fishes and benthic animals. Distribution: Tropical and sub-tropical Indo-West Pacific.

Stock information

For the time period 1965-1995 the estimated biomass of Nemipterus spp. declined to less than 3% by 1995. The last reported major stock assessment for Nemipterus hexodon was in 1999 when MSY was estimated at 22,407 and 20,465 tonnes using Schaefer and Fox models respectively. As Nemipterus hexodon is caught in a mixed species and multi-gear tropical fisheries, shortage of data leads to uncertainty on current status of the stock. Latest FAO catches for Nemipterus spp. were around 40,000 tonnes during the 2008-2009 period. The species is one of the top 14 commercially important (based on catch volume) species in the Gulf of Thailand and contributes to 66 percent of the total catch in the Gulf. Eight of these species are overexploited and the remaining 6 are fully exploited. Threadfin bream is classified as fully fished. In general, demersal fish species show a dimmer picture than pelagic ones. This is probably because demersal fish often have a higher market value and are often captured by trawls. Another alarming phenomenon is overcapacity, i.e. the number of fishing vessels targeting the species or the total fishing effort the vessels can potentially exert on the species is too high. Overcapacity has occurred to all the top 14 species. Southeast Asian Fisheries Development Centre (SEAFDEC) has responsibility for assessing this and other stocks in the region.

Capture Information

Nemipterus hexodon is caught in a multigear and multispecies demersal fisheries in Gulf of Thailand. The species appears to be part of a straddling stock which inhabits Andaman Sea, Gulf of Thailand, South China Sea and Arafura Sea. Thai vessels are known to operate both within The Thai EEZ and high seas. So, there is a scarcity of data on whether the species of interest is caught from EEZ waters, High seas or from Thai vessels licensed and unlicensed operating in neighbouring countries waters.
