SUMMARY

SUMMARY

IDENTIFICATION

SCIENTIFIC NAME(s)

Nemipterus hexodon

SPECIES NAME(s)

Ornate threadfin bream

COMMON NAMES

threadfin bream

There is no current information available about the population structure of this species in the Gulf of Thailand.


ANALYSIS

Weaknesses

There is a lack of information on levels and rates of bycatch of vulnerable species. There is no onboard observer coverage. According to Pitcher and Pramod (2005) stock specific reference points are calculated for many commercial fish, but not employed in a largely open access Thai fisheries.

Fisheries

Within FishSource, the term "fishery" is used to indicate each unique combination of a flag country with a fishing gear, operating within a particular management unit, upon a resource. That resource may have a known biological stock structure and/or may be assessed at another level for practical or jurisdictional reasons. A fishery is the finest scale of resolution captured in FishSource profiles, as it is generally the scale at which sustainability can most fairly and practically be evaluated.

OVERVIEW

Weaknesses

There is a lack of information on levels and rates of bycatch of vulnerable species. There is no onboard observer coverage. According to Pitcher and Pramod (2005) stock specific reference points are calculated for many commercial fish, but not employed in a largely open access Thai fisheries.

1.STOCK STATUS

STOCK ASSESSMENT

According to Krongprom et al., (2003) estimated biomass of Nemipterus spp. declined to less than <3% by 1995 (1965-1995 time period). The last reported major stock assessment for Nemipterus hexodon was in 1999 (Isara 1999) who estimated MSY as 22,407 and 20,465 tonnes using Schaefer and Fox models. 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.

SCIENTIFIC ADVICE
Reference Points

The last reported major stock assessment for Nemipterus hexodon was in 1999 (Isara 1999) who estimated MSY as 22,407 and 20,465 tonnes using Schaefer and Fox models. Reported catches from Thailand do not have a detailed breakup of Threadfin breams (Nemipterus fishes) by species. Latest FAO catches for Nemipterus spp. were around 40,000 tonnes during the 2008-2009 period for Thailand.

2.MANAGEMENT QUALITY

COMPLIANCE

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 scarcity of data on whether the species of interest is caught from EEZ waters, High seas or from Thai vessels licensed / unlicensed operating in neighbouring countries waters.
