[Show abstract][Hide abstract] ABSTRACT: The study of the lenght weight relationships and condition factors of the brackiswater fishes found in Kuala Gigeng was conducted. The objective of the present study was to evaluate the growth pattens and condition factor of the belanak (Mugil cephalus), seriding (Ambassis koopsii) and petek (Leiognathus
fasciatus). The sampling was conducted for eight time on July 2011 by using gillnet and castnet. The results showed that the belanak (M. cephalus) and seriding (A. koopsii) have allometric negative growth patten, while the petek (L. fasciatus) has an allometric positive. In addition, the relative weight condition factor’s was higher than 100. And the Fulton’s condition factor were not different significantly among fishes. Indicating the condition of the Kuala Gigeng is relatively in good condition and support fish growth as well.
[Show abstract][Hide abstract] ABSTRACT: This study was carried out to assess the socio-economic and ecological impacts of forest products harvesting in Central Aceh, Indonesia. The assessment included: Pinus merkusii and other non-timber forest products (NTFP). The study focussed on the utilisation of P. merkusii, economic analysis of existing timber harvesting operations and comparison with Indonesian reduced impact loggin guidelines. Also the contribution of NTFP to the livelihoods of the local people in the area, their vulnerability to harvesting, and availability trends were studied. Data were obtained by using semi-structured questionnaires for open interviews with farmers and concessionaires in the study area. Data analysis was done by employing gross margin analyses, and descriptive and dierential statistics. The results showed that reduced impact logging guidelines are not yet implemented in this region. Forest concessionaires in the study area had an average profit of Rp 197m 3 from logging activities. Logging also contributed to the welfare of local people in terms of job opportunities and the implementation of agro-forestry programs. The harvest of NTFPs is an additional activity, contributing about 25% to the income of the local people in this area. The proportion of NTFP harvesters is low and species are mainly sold to collectors in Central Aceh and Bireun. The intensity of NTFP harvesting is aected by road conditions and market locations.
