Abstract:
PURPOSE: A undaria peterseniana mass production method by inducing the regeneration and aging of undaria peterseniana free-living gametophytes is provided by securing the optimal condition for the regeneration and aging of the Undaria peterseniana free-living gametophytes. CONSTITUTION: Zoospores are released from an apothecium site of Undaria peterseniana. The released zoospores are cultured, and form gametophytes. Separate the gametophytes formed into female and male gametophytes. Culture the separated female and male gametophytes until the gametophytes reach the respective diameter of 3-10mm. Cut the cultured female and male gametophytes in the respective size of 50-400 micrometers. Culture the excised female and male gametophytes under the cell count of 3-25 cell/ind., the temperature condition of 5-20deg. C , the illumination of 5-40micromolm-2s-1, and the photoperiod of 10:14(Light:Dark)-14:10(L:D). Cross-fertilize the cultivated female and male gametophytes. Culture the gametophytes in a liquid culture medium of PESI(Provasoli`s enriched seawater media). Culture the female and male gametophytes until the gametophytes reach the diameter size of 5-6mm. Excise the female gametophytes in the size of 50-100 micrometers. Excise the male gametophytes in the size of 60-150 micrometers. Culture the female gametophytes under the cell count of 3-8 cell/ind., the temperature condition of 10-20 deg. C, the illumination of 15-30 micromolm-2s-1, and the photoperiod of 10:14(Light:Dark).

Abstract:
PURPOSE: A laver-derived high temperature resistant protein in bacteria, algae, and plants and a gene encoding the protein are provided to enhance gene expression and laver production. CONSTITUTION: A protein which is isolated from laver and has high temperature resistance contains an amino acid sequence of sequence number 1. The protein is a 15kDa protein with 144 amino acids. A gene encoding the protein is a cDNA having a sequence of sequence number 2. A recombinant vector contains the gene, HTR2. A transformant is prepared by introducing the recombinant vector to the host such as bacteria, sea algae, or plants.
Abstract:
A method for mass-producing gametophytes of Kjellmaniella crassifolia is provided to be usefully used for ecological restoring of the endangered Kjellmaniella crassifolia through mass-proliferation of the gametophytes and contribute to income increase of a fisherman by diversifying species of culture fishes. A method for mass-producing gametophytes of Kjellmaniella crassifolia comprises the steps of: (a) after cutting apothecia of Kjellmaniella crassifolia, removing impurities therefrom with sterile seawater; (b) inducing the apothecia to release zoospores; (c) germinating the released zoospores in a liquid culture medium or a solid culture medium to form gametophytes; (d) after aging the formed gametophytes in a solid medium, isolating them into female and male gametophytes; (e) homogenizing the isolated female and male gametophytes using a homogenizer and then cutting them to have a size of 10-50 micrometers; and (f) culturing the cut female gametophytes in a liquid medium at a temperature of 10-24 deg.C with the intensity of radiation of 15-70 muE/m^2xs^-1 and culturing the cut male gametophytes in a liquid medium at a temperature of 1-10 deg.C with the intensity of radiation of 40-80 muE/m^2xs^-1.

Abstract:
A system for hatching fish eggs with a filtering type sterilizing device is provided to improve the hatching ratio, to solve the problems of the use of chemicals and to be used for indoor high-density production of fresh water fish. A system for hatching fish eggs with a filtering type sterilizing device includes a hatching tank, a fry tank, a water-collecting heating tank, a sterilizing/purifying unit and a moving unit. The fish eggs are hatched in the hatching tank. The hatched fries gather in the fry tank. The water discharged from the fry tank are collected and heated in the water-collecting heating tank. The sterilizing/purifying unit sterilizes and purifies the water that passed through the water-collecting heating tank. The moving unit is installed on a lower end of the system for hatching fish eggs. The hatching tank, the fry tank, and the water-collecting heating tank are made of transparent materials.
