2.2. Study site and fish sampling
Fish sampling was conducted during the wet season from a
number of rain-fed rice fields in different localities in Sisaket
Province, Thailand (Table 1). Sisaket Province is considered to be
one of the least developed regions in Thailand according to the per
capita GDP. Farming is the major occupation of 80% of the
population, while the region supplies 36% of the country’s rice.
There is only one rice crop each year. The area is largely flat with
considerable seasonal wetland areas, an extreme dry season and an
infertile soil. The fishing gear used in the rice fields was gillnets and
fishing rods using small green frogs and worms as baits. A total
number of 15 climbing perch (Anabas testudineus), 15 walking
catfish (Clarias macrocephalus), 15 snakehead (Channa striatus), 10
blackline rasbora (Rasbora borapetensis), 5 swamp barb (Puntius
brevis) and 5 freshwater prawns (Macrobrachium nipponense) were
collected. Each specimen was placed in an air-tight polyethylene
bag and immersed in plenty of crushed ice until being transported
to the laboratory. A portion of muscle was removed from each
specimen, devoid of skin and bone, placed in an air-tight
polyethylene bag and stored at 20 8C. Samples were transported
to UK in dry ice for lipid analysis.
