were the most abundant PUFA in the muscle lipids of all species (Table 3), followed by linoleic acid (C18:2n-6), linolenic acid (C18:3n-3) and eicosapentaenoic acid (C20:5n-3). There was a considerablevariationinthe levels of the above fatty acids amongthe
species (Table 2) but not within the species (Table 3). However, A. testudineus, showed considerable variation in the levels of several PUFA between fish coming from the three localities. A. tesudineus from Lom Sak had lower n-3/n-6 polyunsaturated fatty acid (PUFA) ratios compared to fish coming from rice fields in Pho and Nong Waeng subdistricts (Table 2). A similar trend, although not significant, was also observed for C. macrocephalus sampled from LomSak and Pho subdistricts, which probably reflects the fatty acid composition of the natural food in these sites. Furthermore, there was considerable variation in the levels of PUFA between the six species (Table 3). C. striatus contained the highest levels of C22:6n-3 (13.34% of total FA, Table 3) in muscle lipids while M. nipponense, P. brevis and C. macrocephalus had significantly lower levels. C. striatus also contained the highest levels of C20:4n-6 (14.6% of total FA), which were significantly higher than those found in R. borapetensis and P. brevis. C. striatus and A. testudineus had much lower levels of C18:3n-3 and of C20:5n-3 compared to the other species. P. brevis had comparable levels of C18:3n-3 and C22:6n-3 in their lipids, while the prawn M. nipponense contained the highest levels of C20:5n-3 and was the only species with more C20:5n-3 than C22:6n-3 (Tables 2 and 3). R. borapetensis contained the lowest levels of total n-6 PUFA and comparably high levels of total n-3 fatty acids compared to the rest of the species and consequently these fish contained significantly higher n-3/n-6 PUFA ratios in their tissues (Table 3).
