Population biology and assessment of representatives of the family CarangidaeCarangoides bajad and Gnathanodon speciosus (Forsskål, 1775), in the Southern Arabian Gulf

Population dynamics and fishery benefits of a large legal size of a pelagic sportfish, the Talang queenfish, Scomberoides commersonnianus, in northern Australia

“…Grandcourt et al (2004) found an absence of alternating translucent and opaque bands that could be interpreted as annuli in the sagittal otoliths of two similar sized tropical carangids, Gnathanodon speciosus and Carangoides bajad. Crabtree et al (2002) also incurred a similar problem with a large tropical carangid (Trachinotus falcatus) and determined 17% of otoliths were unreadable.…”

“…However, the growth rate of Talang queenfish is very different to what has been observed for similar-sized Carangids from tropical regions. In the Southern Arabian Gulf, Grandcourt et al (2004) found G. speciosus and C. bajad to both grow quickly attaining lengths corresponding to 85% of L ∞ by age 3 years. In contrast, Talang queenfish attain a length corresponding to 85% of L ∞ at 17 years and 1195 mm FL.…”

The Growing Need for Sustainable Ecological Management of Marine Communities of the Persian Gulf

“…Despite existing regulations governing fishing effort (e.g., bans on fish trawling), many fishery species in the Gulf have been heavily exploited, and fishing effort already exceeds optimum levels for most demersal species (Grandcourt et al 2004(Grandcourt et al , 2009Grandcourt, in press). Throughout the Gulf, data on stock status are limited, and many catch data are recorded only to the family level, reducing the ability of managers to use statistical catch-at-age methods for conducting species level assessments (Grandcourt, in press).…”

An overview of wetlands of Saudi Arabia: Values, threats, and perspectives

“…There is little disagreement that the loss of these wetlands and their associated services will involve huge costs to and social upheaval of their stakeholders. Owing to loosely enforced fisheries regulations, the most important natural resource after oil may be at considerable risk (Grandcourt et al 2004). Domestic and industrial wastewater as well as pollution due to oil exploration, production and transport may also constitute a persistent threat to the ecological integrity of the coastal waters of the Gulf (Krupp and Abuzinada 2007;Sheppard et al 2010).…”
