The population of Jernang rattan (Daemonorops draco) in Jebak Village, Batanghari District, Jambi Province, Indonesia

Abstract

The population of demersal fishes tends to be decline in the last few decades. The decline was due to the increased of intensive catches, fishing effort and illegal fishing practices. This study aimed to examine aspects of population dynamics such as mortality, recruitment, opportunity capture and population estimation. The study was conducted in six locations at Tambelan waters, on 4-16 November 2010. Collected data included the fish species, size and biomass catch. The analyses performed included mortality, recruitment, opportunity capture and population estimates (VPA). The data indicated that the Genus of Nemipterus and Lutjanus possess the highest total mortality rate that was respectively 1.62 and 2.55. The highest recruitment presentation of the population which has an annual period as Pentapodus was 16%. Catch opportunities tend to be higher than actual fishing, while the alleged biomass of steady state conditions reached 12.2 tons/yr.

Anti-inflammatory, pro-proliferative and antimicrobial potential of the compounds isolated from Daemonorops draco (Willd.) Blume

“…Daemonorops draco (Willd) Blume, belonging to the Arecaceae family, is a native species from Indonesia, which has been traditionally used by the Momok, Anak Dalam and Talang Mamak tribes as a remedy for treating wounds because of its anti-haemorrhagic, antiinflammatory and healing properties (Sulasmi, 2012a;2012b). The D. draco species has been reported to contain triterpenes, flavans, chalcones (Nasini & Piozzi, 1981), diterpene acids (Piozzi et al, 1974) and biflavonoids (Merlini & Nasini, 1976).…”
