Socioeconomic study and economic value of living fossil,Lingula sp.in mangrove ecosystem in Trat Province,Thailand

This paper is the first recorded economic value of living fossil,an evaluation of the basic economic value of Lingula,based on the direct utilization of households for food and sale.Twenty-one local fishermen who collected Lingula in Trat Province were focused on by using interview questionnaires.The animal habitats are influenced by the encroachers’age,gender and harvest method.The total economic value in 2011 was around two million baht.Those who possess fishing gear and have more money can have greater access to the product The local communities in Nong Khunsong sub-district are successful in collecting the Lingula and in doing local business.The market channel analysis is conducted at local,provincial and national levels and short market chains are demonstrated in the form of a wholesale market in the Lingula trade.This represents significant consumption by the local communities.The study further recommends sustainable conservation and management efforts at a local scale.     

Possible use of Lingula sp.(Phylum Brachiopoda)as a dissemination strategy to promote sustainable development in Fangchenggang mangrove,China

The economic marketability of a brachiopod,Lingula was studied at three coastal mangrove sites,specifically based on socioeconomic parameters from 10 villages that utilized Lingula along Pearl Bay,Beilun Estuary Marine Nature Reserve,China.The significantly highest density of Lingula was at Jiao Dong(48.2±35.14 individual/m~2)whereas the biomass of Lingula was highest(0.76±0.22 g/individual)at Gui Lao Bu.The shell size of the largest specimen was still less than that in other references.The socioeconomic study of the population related to Lingula involved a small group,and no relationship could be determined among the parameters of age range,education level,occupation,and financial status.The total economic value(320,927.4 Yuan)was based on the value of consumption whereas the value from sales was very low as recorded from Shan Xin over a three-month season.Analysis of the results to determine strengths,weaknesses,opportunities,and threats was undertaken to identify the potential of Lingula sp.to be promoted and supported in the market as a novel source of income for the local community who are associated with mangrove resources;and also to examine its potential as a new food source for the rapidly growing population of China.

The significantly highest density of Lingula was at Jiao Dong (48.2 ± 35.14 individual/m²) whereas the biomass of Lingula was highest (0.76 ± 0.22 g/individual) at Gui Lao Bu. The shell size of the largest specimen was still less than that in other references.
