Abstract：

Components　of　chromophoric　dissolved　organic　matter　(CDOM)　from　eight　coastal　land-based　shrimp　ponds　in　the　Minjiang,　Mulan,　and　Jiulong　rivers　of　subtropical　southeastern　China　were　determined　by　fluorescence　excitation　emission　matrix　spectroscopy　combined　with　parallel　factor　analysis　(EEMs-PARAFAC).　Four　separate　fluorescence　components,　including　two　protein-like　components　(C1,　C4)　and　two　humic-like　components　(C2,　C3),　were　identified　as　the　dominant　components　of　the　CDOM　in　these　shrimp　ponds.　The　fluorescence　indices　(FI,　BIX,　and　HIX)　suggest　that　the　CDOM　of　shrimp　ponds　shows　low　humification　and　is　mainly　derived　from　spontaneous　sources.　The　protein-like　and　humic-like　components　have　similar　sources　and　exhibit　a　similar　geochemical　behavior.　The　salinity　is　negatively　correlated　with　all　CDOM　fractions,　whereas　the　DOC　concentrations　show　only　a　positive　correlation　with　the　humic　fractions　of　the　CDOM.　This　study　provides　a　scientific　basis　for　the　photochemical　properties　of　CDOM　in　shrimp　ponds.　©　2019,　Science　Press.　All　right　reserved.
