    To elucidate the spatio-temporal dynamics of the harmful dinoflagellate Karenia mikimotoi and the relationship with environmental conditions in Uwajima Bay and its adjacent waters, we conducted field observations and analyzed the data in 2018 when a bloom occurred and in 2019 when it did not occur. In 2018, cell density of K. mikimotoi increased in Uwajima Bay, and then the bloom corresponding to low salinity water expanded to a broad area of the adjacent waters, suggesting that the spatio-temporal dynamics of the species were controlled by fresh water and nutrient discharges from rivers, and by passive transport due to a surface residual current. In 2019, although vegetative cells overwintered at low density, they did not form a bloom, possibly due to the environmental conditions for their growth, a large-scale intrusion of warm water (kyucho), and the existence of competing species.

    The Tama River is an urban river flowing throughout the Tokyo Metropolis. The water quality has been improved and a large number of wild ayu Plecoglossus altivelis migrate upstream in recent years. We conducted an epidemiological survey on two fish pathogens, Flavobacterium psychrophilum and Edwardsiella ictaluri, among ayu and other wild fish species based on PCR and culture methods at four sites (lower-, middle-, upper-reaches and tributary) in the Tama River basin from May 2011 to November 2012. F. psychrophilum was detected in 15 fish species including ayu throughout the survey period, and the occurrence of F. psychrophilum infection (bacterial cold-water disease) among ayu was observed in upper-reaches and tributary areas between mid-and late June of both years. On the other hand, E. ictaluri was detected in 7 fish species mainly in summer and late fall of both years, and E. ictaluri infection of ayu with mass mortality occurred in the tributary area in late August 2012 only. It is speculated that the unusually high water temperature during August 2012 (approximately 6 degrees C higher than that of 2011) served as a predisposing factor in this mortality. Disease occurrence in riverine ayu might be attributable to the subclinical infection status of fish and stress conditions imposed by the environment.

    昨今、養殖場では様々な魚病が頻発し、生産効率や商品価値を著しく低下させている。魚病被害抑制のためには、密な検査により魚病発生を早期に探知し、発生拡大の前に封じ込め・治療を行うことが不可欠であるが、現行の検査方法は取り上げや解剖による魚体へのダメージから養殖業者に敬遠されている。そこで本研究では環境水をサンプルとした、魚体の取り上げを必要としない非侵襲的な魚病検査手法を確立することを目的とする。
    本年度は、魚類の魚病感染時に魚体から放出される生体物質の分子生物学的解析を中心に行った。魚病細菌Edwardsiella anguillarumを人為感染させたマダイを水槽内で維持して経時的に飼育水を採取し、飼育水に含まれるマダイ由来RNAを網羅的に検出したところ、感染魚飼育水で複数のRNAが非感染魚飼育水に比べ有意に増加しており、これらが病原体感染に対するマダイの生体応答を反映したRNAであると考えられた。
    そこでこれらのRNAを感染マーカー候補として選定し、定量PCR系による定量系を構築、飼育水中の発現量を測定したところ、対象としたいずれのRNAも感染魚飼育水中の発現量が非感染魚飼育水に比べ数十~数百倍高かった。さらに飼育試験中に経時的に取り上げたマダイ組織中のRNAマーカー発現量も測定したところ,飼育水中RNAと似た発現変化を示した。
    以上の結果から、感染魚飼育水中には感染への応答履歴を示すRNAが放出されており、これらが感染を探知できる非侵襲検査マーカーとなる可能性が考えられた。
