Abstract

Harvest monitoring is an alternative strategy to determine the impacts of exploitation which is useful for conservation strategies. We monitored one of the exploited turtles, C. amboinensis in three provinces that have high rates of turtle harvesting, North Sumatra, South Sumatra, and Central Kalimantan. Harvest monitoring is carried out by measuring harvested specimens based on three characters comprising median carapace length (MeCL), maximum carapace width (MaCW), and biomass of turtle (Wt). We compared the data with the previous monitoring in 2006. This study showed that the harvested size turtle was relatively similar to 2006 monitoring, in North Sumatra and Central Kalimantan. Furthermore, in North Sumatra, bigger individuals and larger quantities of the juvenile were recorded compared to previous monitoring whereas in Central Kalimantan the harvest characteristics showed a similar pattern compared to 2006 monitoring. The female individuals were dominantly harvested in all locations, with detailed sex ratio male: female 1:1.7 (North Sumatra), 1:1.6 (South Sumatra), and 1:1.1 (Central Kalimantan). In the current monitoring, there was no evidence of a decline in harvest size that might indicate that the harvest activities of C.amboinensis in Indonesia are not yet detriment to the wild populations. However, to reveal the sustainable harvest of this species in the future, long-term monitoring and intense supervision are needed
