Fish fauna of shallow waters of Aki Nada, Seto Inland sea, Japan

瀬戸内海安芸灘に位置する大崎上島の沿岸魚類相について，餌釣りと潜水観察による調査を実施した。ガラモ場の存在する桟橋を中心に調査定点を島の南部北部それぞれに設定し，オキアミ類とゴカイ類を餌に約10名が1時間釣りを行う作業を2007年5月から2008年3月まで隔月で実施し，出現魚類の季節変化を検討した。また，2007年5月から7月にかけて，屋代島から竹原までの安芸灘広域に9ゾーン26調査点を設け，同様の調査を実施し，出現魚類の水域ゾーン間の相違を検討した。本調査により総計29科63魚種を記録した。そのうち高水温期にのみ出現する南方系魚種は4種のみであった。記録した魚種の76％（48種）は伊予灘で記録されているものであった。一方，宇和海での魚類相データとの魚種共通率は30％前後に留まり，安芸灘を含む伊予灘以北の水域が生物地理学的に中間温帯区（西村，1981）と定義されていることの妥当性が裏付けられた。大崎上島において周年および冬期を除き常時記録されたのは，カサゴ，メバル，ハオコゼ，クジメ，アサヒアナハゼ，マダイ，ウミタナゴ，スズメダイ，メジナ，コブダイ，ホシササノハベラ，キュウセン，ホンベラ，クラカケトラギス，ホシノハゼ，イトヒキハゼ，ヒガンフグ，コモンフグであった。これら18魚種の多くは安芸灘広域調査においても広く出現が認められ，安芸灘の浅海魚類群集の基本構成種と考えられた。ホシササノハベラは愛媛県中島周辺水域での出現頻度が極めて高く，同種の安芸灘における主要な個体群が安芸灘南西エリアに存在する可能性が示唆された。また，過去に瀬戸内海での記録のないホシノハゼが安芸灘広くに確認され，急速に分布拡大を進めていることが示唆された。We surveyed fish fauna at shallow waters of Aki Nada, Seto Inland Sea by the line fishing census, using small hooks attaching clamworms or krills as baits, during May 2007 - March 2008. We set up survey points at piers with Sargassum belt in Osaki-Kami Shima Island, and conducted the census (ca. 10 person x 60 min at each) bimonthly to analyze seasonal differences of fish fauna. In order to evaluate geographic variation of fish fauna, we also held the census at 26 survey points of nine zones situated a wide area in Aki Nada during May-July, 2007. A total of 63 species of 29 families were recorded. Of 63 species, 76 % were commonly recorded in Iyo Nada region. In contrast, the common species ratio fell to ca. 30% in comparison with data recorded in Uwa Sea region, which strongly supports the validity of the border of biogeographical regions between “Warm temperate region” including Uwa Sea and “intermediate temperate region” including Iyo Nada and Aki Nada (Nishimura, 1981). The almost year-round occurrences in the Osaki-Kami Shima were admitted in the following 18 species, Sebastiscus marmoratus, Sebastes inermis, Hypodytes rubripinnis, Hexagrammos agrammus, Pseudoblennius cottoides, Pagrus major, Ditrema temmincki, Chromis notata notata, Girella punctata, Semicossyphus reticulatus, Pseudolabrus sieboldi, Halichoeres poecilopterus, Halichoeres tenuispinnus, Parapercis sexfasciata, Istigobius hoshinonis, Cryptocentrus filifer, Takifugu pardalis, Takifugu poecilonotus. Most of these species commonly occurred in the survey zones in Aki Nada waters, suggesting that these are core components of fish fauna in shallow waters of Aki Nada

Telephone Cognitive-Behavioral Therapy for Subthreshold Depression and Presenteeism in Workplace: A Randomized Controlled Trial

Subthreshold depression is highly prevalent in the general population and causes great loss to society especially in the form of reduced productivity while at work (presenteeism). We developed a highly-structured manualized eight-session cognitive-behavioral program with a focus on subthreshold depression in the workplace and to be administered via telephone by trained psychotherapists (tCBT).We conducted a parallel-group, non-blinded randomized controlled trial of tCBT in addition to the pre-existing Employee Assistance Program (EAP) versus EAP alone among workers with subthreshold depression at a large manufacturing company in Japan. The primary outcomes were depression severity as measured with Beck Depression Inventory-II (BDI-II) and presenteeism as measured with World Health Organization Health and Work Productivity Questionnaire (HPQ). In the course of the trial the follow-up period was shortened in order to increase acceptability of the study.The planned sample size was 108 per arm but the trial was stopped early due to low accrual. Altogether 118 subjects were randomized to tCBT+EAP (n = 58) and to EAP alone (n = 60). The BDI-II scores fell from the mean of 17.3 at baseline to 11.0 in the intervention group and to 15.7 in the control group after 4 months (p<0.001, Effect size = 0.69, 95%CI: 0.32 to 1.05). However, there was no statistically significant decrease in absolute and relative presenteeism (p = 0.44, ES = 0.15, -0.21 to 0.52, and p = 0.50, ES = 0.02, -0.34 to 0.39, respectively).Remote CBT, including tCBT, may provide easy access to quality-assured effective psychotherapy for people in the work force who present with subthreshold depression. Further studies are needed to evaluate the effectiveness of this approach in longer terms. The study was funded by Sekisui Chemicals Co. Ltd.ClinicalTrials.gov NCT00885014
