Measurement of Diurnal Body Tilt Angle Distributions of Threeline Grunt Parapristipoma trilineatum Using Micro-Acceleration Data Loggers
Autor: Hideaki Tanoue, Teruhisa Komatsu, Alabsi Natheer, Isamu Mitani, Shinichi Watanabe, Yuuki Watanabe, Akira Hamano, Nobuyuki Miyazaki
Publikováno v: Journal of Marine Science and Engineering, Vol 1, Iss 1, Pp 3-9 (2013)
The body tilt angle of a fish has a large effect on the acoustic target strength. For an accurate estimation of fish abundance using acoustic methods, it is necessary to measure body tilt angles in free-ranging fish. We measured diurnal body tilt ang

Three synergistic growth-related mechanisms in the short-term survival of larval Japanese anchovy Engraulis japonicus in Sagami Bay
Autor: Akinori Takasuka, Isamu Mitani, Ichiro Aoki
Publikováno v: Marine Ecology Progress Series. 270:217-228
The 'growth-mortality' hypothesis, which holds that larger and/or faster growing individuals will have a higher probability of survival, currently includes 3 functional mechanisms (hypotheses) in its theoretical framework: 'bigger is better', 'stage

Evidence of growth-selective predation on larval Japanese anchovy Engraulis japonicus in Sagami Bay
Autor: Isamu Mitani, Ichiro Aoki, Akinori Takasuka
Publikováno v: Marine Ecology Progress Series. 252:223-238
Growth-selective predation mortality was demonstrated for postlarval Japanese anchovy Engraulis japonicus in field research. The larval anchovy and their predatory fish were simultaneously captured by a trawl in Sagami Bay during October to November
