 note = {[Author Abstract]Chlorophyta Ulva pertusa is easy to polyculture with fish in mariculture farms. Therefore, it has become a useful seaweed for the mitigation of eutrophication in these farms. In order to determine the oxygen budgets for this species, an experiment was conducted to monitor their respiration in culture. A respiration chamber of 750 ml was made by combining two glass funnels of a membrane filter. One g of U.pertusa was set in the chamber. The experiment was carried out on a window side of the rearing laboratory from January 5 to 11,1997. Sea water in the tank in which was cultured the devil stinger Inimicus japonicus was pumped into the chamber by a peristaltic pump at a rate of 30 ml/min. The inlet water and outlet water of the chamber were drifted alternately to an oxygen electrode cell every 15 minutes. The process of which was controlled by a timer. The dissolved oxygen contents were continuously determined by a DO meter (YSI-57) and recorded on a pen-recorder (EYELA-TR-250). The difference of oxygen content between inlet and outlet was determined after the recordings. The water temperature in the chamber was maintained at 23.4±0.85℃ by a thermostat. Sun light was illuminated the chamber during the day. The oxygen budgets in U.pertusa were affected by the weather. The amount of oxygen supplied by the U.pertusa was 22,238 ml/kg/d on cloudy days, 20,790 ml/kg/d on clear days, and 2,124 ml/kg/d on rainy days. The maximum amount of oxygen supplied was found on cloudy, not fine days. Total amount of oxygen produced during the day was 17,392 ml/kg/h, and the oxygen consumed at night was 4,728 ml/kg. The difference between production and consumption was +12,664 ml/kg. The oxygen produced during the day was 3.68 times greater than the oxygen consumed at night.[著者抄録]アナアオサと魚介類の複合養殖における酸素収支を解明する目的で, アナアオサの酸素収支を日周変化の面から自動的に記録した。その測定は平田ら^<3)>のオニオコゼの呼吸測定法に準じて行った。アナアオサは7時から16～17時ころまでの日中には酸素放出によりその放出量は約4000ml/kg/hに達したが, 夜間には200～300ml/kg/h程度の酸素吸収が観察された。日中の正午前後に酸素放出量の一時低下が見られたが, それはアナアオサの生理機構によるものと思われた。日中における酸素の総生産量は6日間平均で17,392ml/kg/hであり, 夜間における酸素消費量は4,728ml/kg/hであった。よってその差は12,664ml/kg/hであった。また, 酸素の生産量は消費量の3.68倍と算出された。, 記事区分：原著, application/pdf},
