To study the effects of marine environmental on thallus of Pyropia dentata (Rhodophyta), I analyzed water temperature, salinity and water quality at the Haenam aquafarm in southern coast of Korea from September to December, 2016. Composition of amino acid and photosynthesis pigment on growing season of P. dentata were studied. Thallus samples were collected at the aquafarm in October and November. Mean water temperature and salinity ranged from 23.11 to 10.93℃ and 30.89 to 32.53 psu, respectively. Dissolved total nitorgen (DTN), dissolved total phosphorus (DTP), total nitrogen (TN), total phosphorus (TP) and chemical oxygen demand (COD) ranged from 0.108~0.282 mg/L, 0.004~0.017 mg/L, 0.164~0.399 mg/L, 0.007~0.021 mg/L and 0.900~1.500 mg/L, respectively. Concentration of DTN, DTP, TN, TP were highest in September and were lowest in November. Proximate composition, amino acid and photosynthetic pigment with P. dentata sampled from aquafarm in October and November were analyzed. Contents of moisture and crude protein, crude lipid, crude ash, carbohydrate were 11.05±0.04, 34.52±0.61, 0.09±0.01, 20.03±0.18, 34.31±0.67% in October and 14.21±0.21, 27.91±1.41, 0.38±0.09, 12.18±0.28, 45.32±1.69% in November. Photosynthetic pigment of Chl. a, PE and PC concentration of P. dentata thalli were 1.609±0.074, 7.848±3.990, 4.288±1.934 mg/g in October and 0.145±0.013, 6.081±0.393, 3.902±0.227 mg/g in November. The pigment concentration was relatively high in October than November. Total amino acid contents were 24,860.00±911.76 mg/100g in October and 21,039.55±825.53 mg/100g in November. Free amino acid contents were 2,310.52±177.93 mg/100g in October and 2,474.87±141.43 mg/100g in November. These results show that proximate composition, photosynthetic pigment content and amino acid content of P. dentata are affected by changes in marine environment seasonally.
