| Abstract: | Contents of proximate composition,total carotenoids,fatty acids,and amino acids were compared in five species of aquatic plants,Potamogeton maackianus,P.pusillus,P.crispus,Alternanthera philoxeroides and Myriophyllum spicatum in prawn and crab culture ponds.Besides,combined with the growth characteristics of five species of aquatic plants and their inhibition of sediment resuspension,the application value of these five species of aquatic plants in freshwater prawn and crab culture was comprehensively evaluated.The results showed that:(1)the moisture of P.crispus was significantly higher than that of the other four species plants,the crud protein and crude lipid contents of P.maackianus,P.pusillus and A.philoxeroides were significantly higher than M.spicatum and P.crispus.Besides,the total sugar and total carotenoids contents of P.maackianus and A.philoxeroides were also significantly higher than P.pusillus,P.crispus and M.spicatum;(2)the contents of saturated fatty acids(SFA)and monounsaturated fatty acids(MUFA)were significantly higher in P.maackianus and P.crispus than those in P.pusillus,A.philoxeroides and M.spicatum,while the levels of polyunsaturated fatty acids(PUFA)were significantly higher in A.philoxeroides and M.spicatum than P.maackianus,P.pusillus and P.crispus(P<0.05);(3)the total essential amino acids(EAA),total non-essential amino acids(NEAA)and total amino acids(TAA)were significantly higher in P.maackianus and P.pusillus than those in P.crispus and the M.spicatum.Besides,the maximal EAA/TAA value was observed in P.pusillus and the minimal EAA/TAA value in M.spicatum.In summary,the nutritional quality of different aquatic plants in this study are different and there are certain complementarities,and the choice of aquatic plants should be based on its nutritional quality,prawn and crab preferences and environmental factors. |
