To understand the effects of oceanographic condition on the harvest of laver and establish the basic environmental data for cultivation farm of laver, a sedes of survey was carried out in Biin Bay, west coast of Korea from January to June. 1987. Flood current running northward with the velocity of O.25~0.30m/s at outer of Oryok-to and westnorthward with O.20m/s at mouth of bay. At ebb tide, the current flow southward with O.25-0.35m/s at around Oryok-to and ' outheastward with 0.25m/s at mouth of bay. Water quality was nearly normal as unpolluted sea water except the concentration in TSS which showed higher than 2nd class criterion of sea water quality. The amount of nutrients(nitrate and phosphate) were lower during the culitivation periods of laver. Total 54 species of phytoplankton and 14 species of zooplankton were identified from all sample collected. Dominant species were Eucampia zodiacus, Skeletonema costatum.Coscinodiscus sp. as phytoplankton and Noctiluca scinitillans, Acartia clausi as zooplankton. The total standing crop of phytoplankton was ranged of 3,000 to 1,375,400 cell/ℓ and that of zooplankton was 300 to 50,600 individuals/ℓ. Average content of chlorophyll a in Biin Bay was 2.82㎎/㎡. Total nitrogen content and chlorophyll a in cultured laver sampled from Biin Bay were higher in Feburary in all and C, D farm's quality index of laver were better than the other farms.
