魚類学雑誌, Apr. 2025, [Reviewed] - Effects of preventing a temperature decrease during winter on reproduction of male small-egged Kajika, Cottus pollux SE
Yasunori Koya; Ryoji Fujii; Daisuke Tahara; Hidenobu Yambe; Takaharu Natsumeda, Last, To investigate the effects of preventing temperature decrease on the reproductive activity of the male cold-water teleost, Cottus pollux SE, testicular development, serum 11-ketotestosterone (11-KT) levels, and physiological responses associated with nesting behavior (i.e., elevation of serum 11-KT levels and accumulation of urine in the urinary bladder) were observed from November to January. Specifically, males were exposed to three different cooling regimes (control, 16 to 6 °C; H1, 16 to 11 °C; H2, 16 to 14 °C), and the results were compared. In addition, the effects of temperature on male reproductive behavior were also clarified. At higher water temperature regimes, the rate of testicular development and serum 11-KT levels were both higher from November to mid-December than from mid-December to January. However, the results showed that high water temperature regimes in the coldest period of winter did not suppress spermatogenesis completely. Conversely, the physiological responses to nesting were affected by high water temperatures, with serum 11-KT levels increasing and urine accumulation in the urinary bladder being suppressed. Furthermore, frequencies of two behaviors associated with nesting, i.e., body undulation and face displays, were also suppressed under high water temperatures (~ 14 °C) compared with normal temperatures (~ 7 °C) during the breeding season. Based on the physiological and behavioral responses to nesting, findings showed that preventing a water temperature decrease during winter suppresses reproductive activity in Cottus pollux SE., Springer

応用生態工学, Mar. 2014, [Reviewed] - Diet composition and food intake of two competitive heron species: the Grey Heron and the Great Egret
Hamao Shoji; Akiba Toru; Natsumeda Takaharu, Last, The Grey Heron Ardea cinerea and the Great Egret A. alba are assumed to have competitive relationship for food resource because of their overlapped feeding habitats. We observed their feeding behaviours in rice paddy fields in central Honshu, Japan. The main diets of both species were pond snails Sinotaia quadrata histrica and weather loach Misgurnus anguillicaudatus, suggesting competition for foods between the herons. Although the frequencies of peck trials and successful pecks were higher in Great Egrets than in Grey Herons, food intake had a tendency to be greater in Grey Herons than in Great Egrets. This inverse result must be caused by the higher proportion of small pond snails in Great Egret diets. Great Egrets frequently peck and obtain smaller foods, and Grey Herons use infrequent chance to obtain larger foods, which may relax the competition in food between the species., Japan Bird Research Association

日本水産学会誌, Mar. 2010, [Reviewed] - Predation by Zacco platypus, Tribolodon hokonensis and Gymnogobius petschiliensis on Ayu (Plecoglossus altivelis altivelis) larvae under light and dark experimental conditions
Tsuruta Tesuya; Koike Ryoto; Takeshima Hirohiko; Natsumeda Takaharu; Iguchi Keiichirou, This study aims to evaluate the predation pressure during daytime and nighttime on larvae of Ayu, Plecoglossus altivelis, by comparing the number consumed by three predatory fish species between light and dark experimental conditions. Four of five individuals for Zacco platypus consumed more Ayu larvae in the light condition than in the dark condition. The number of Ayu larvae consumed by all four individuals for Tribolodon hakonensis in the light condition was about twice that in the dark condition. For Gymnogobius petschiliensis, three of five individuals ate few Ayu larvae, one showed a higher and the other showed a lower feeding activity under the light condition. Because two out of three predators showed a consistently higher feeding activity on Ayu larvae under the light condition, we suggest that the diurnal predation pressure is a selective factor for not only nocturnal drift in Ayu larvae but also concentrating hatching after sunset., 日本魚類学会
