Cesium-137 discharge into the freshwater fishery ground of grazing fish, ayu Plecoglossus altivelis after the March 2011 Fukushima nuclear accidentKei'ichiro Iguchi; Ken Fujimoto; Hideki Kaeriyama; Atsushi Tomiya; Masahiro Enomoto; Shin-ichiro Abe; Toshinori Ishida, The Fukushima nuclear accident led to deposition of radionuclides into the freshwater fishery ground of ayu Plecoglossus altivelis. For the purpose of more comprehensive understanding of the radioactive contamination, cesium-137 (137Cs) was analyzed in running water, muddy sediment, attached algae, and ayu using samples from three river systems with different levels of contamination within Fukushima Prefecture in summer and autumn 2011. The amount of 137Cs contained in water as well as in sediment declined over an interval of two months, although the concentration in sediment samples was up to 10,000-fold higher than that in water samples. The changes in 137Cs concentration of algae showed different courses among the three river systems, the concentration being greater in autumn in the river systems with high and moderate radioactive contamination. 137Cs detected within a single stock of ayu appeared to be excreted rather rapidly with a calculated half-life of approximately 39 days, while the concentration ratio ranged from 103 to 104 l/kg, attaining higher levels than previously reported. These findings indicate that the most important pathway of 137Cs into ayu is via intake of algae as food but that the retention time of 137Cs inside ayu is relatively short. © 2013 The Japanese Society of Fisheries Science.

[Reviewed] Educational significance of fishermen's activities providing opportunities for schoolchildren to play in streamsABE Shin-ichiro; SAJIKI Takahiro; TAMAKI Yasuji; AWATA Satoshi; IGUCHI Keiichiro, In Japanese streams fishermen often give children the opportunity to enjoy natural environments by allowing them to participate in such activities as releasing fish stock and creating spawning sites, as well as by conducting habitat preservation activities, fishing schools and nature observation tours. This study assessed the educational significance of fishermens activities involving schoolchildren using a questionnaire survey of men and women at least 20 years old who were attending an exhibition at the Nikko Laboratory of the National Research Institute of Fisheries Science in August 2010. More than 70% of the respondents acknowledged the educational significance in the people–nature relationship and mental/psychological aspects of such activities; women evaluated the significance of such activities more positively compared with men. In the social life aspect, less than 50% of the respondents acknowledged being motivated to engage in freshwater fisheries activities and to settle in the local community. Meanwhile over 70% thought the activities would improve the appreciation of freshwater fisheries and the local community and inform the value of labor and cooperation. The results suggest most people appreciate the contribution of these fishermens activities in the education of children., The Japanese Society of Limnology

[Reviewed] Feeding territory and variations in behavioural modes of algae-grazing fish Plecoglossus altivelis ryukyuensis (Ryukyu-ayu) in subtropical island streamsSatoshi Awata; Tetsuya Tsuruta; Shin-Ichiro Abe; Yasuji Tamaki; Kei'Ichiro Iguchi, Social and foraging modes in fish often vary between individuals with different body sizes and between populations under different ecological conditions. We studied social and foraging behaviour of algae-grazing fish Plecoglossus altivelis ryukyuensis (Ryukyu-ayu) inhabiting Japanese subtropical island streams. Ryukyu-ayu exhibited four behavioural modes: territorial, schooling, solitary and floating. Their body sizes differed among these modes. Territorial fish predominantly foraged on benthic algae, whereas schooling and solitary individuals frequently consumed drifting materials as well. Schooling fish were smaller than territorial fish, but, unlike some other algae-grazing fish species, did not use schooling to gain access to food within territories. Territorial fish attacked smaller conspecifics but exhibited lateral display towards larger fish and schooling fish while occasionally attacking grazing gobies. Larger fish maintained larger feeding territories and occupied territories for longer periods than smaller fish did. This suggests that, in Ryukyu-ayu, intra- and interspecific food competitions and relative body size can influence diverse behavioural modes and duration of territory occupation. We also found that Ryukyu-ayu foraged more often and had larger feeding territories than ayu P. a. altivelis inhabiting temperate streams. We conclude that foraging strategies of Ryukyu-ayu may have adapted to subtropical island streams, where algal productivity is much lower than that in temperate regions. © 2011 John Wiley &

Effect of fish in rice-fish culture on the rice yieldTetsuya Tsuruta; Motoyoshi Yamaguchi; Shin-ichiro Abe; Kei'ichiro Iguchi, Rice-fish culture, which means the simultaneous culture of rice and fish, is one of the best options to increase food production from limited land and is practiced in many countries in the world. Although many researchers and farmers believe that the rice yield is increased by fish farming in paddy fields, this hypothesis has never been fully tested. Here, we report ecological processes leading to higher rice yields in the rice-fish culture using crucian carp (Carassius complex), which have adapted to the paddy field ecosystem in Japan. We compare the rice-fish and rice-only plots in the experimental paddy field for biota, water quality, and rice yield. Coverage of duckweed and densities of zooplankton and benthic invertebrates in the rice-fish plots were lower than those in the rice-only plots, indicating that fish utilized them as food. NO3-N concentration in the rice-fish plots was higher than that in the rice-only plots, indicating that the increase in NO3-N concentration results from excretion of unutilized food nutrients by the fish. Consequently, rice yield in the rice-fish plots was 20% higher than that in the rice-only plots. The fertilizing effect of the fish excrement probably increased rice yield. © 2010 The Japanese Society of Fisheries Science., Springer Japan

Spawning condition of the Ryukyu-ayu (Plecoglossus altivelis ryukyuensis) in Amami-oshima Island. Ecol. Civil Eng. 12(2), 109-117, 2009Tetsuya Tsuruta; Shin-Ichiro Abe; Toshihiko Yonezawa; Kei'Ichiro Iguchi, We examined spawning condition of the Ryukyu-ayu Plecoglossus altivelis ryukyuensis which is endangered through habitat destruction and decreasing population size and harbored in the Amami-oshima Island in order to contribute to making an effective conservation program. Investigations were carried out in the Yakugachi River which provides the largest habitat for the subspecies, and their eggs attached to substrates occurred only in a reach at 2.4 km away from the river mouth. The principal component analysis which was conducted for environmental variables including water depth, flow velocity, substrate size and silt sedimentation drew the property of spawning site on a transitional zone between riffle and run. The logistic regression analysis conducted for the environmental variables around the spawning site factored out the substratum adhesion as a determinant variable to explain presence/absence of spawning ground. A lot of net-spinning caddis larvae were observed in the spawning site of the Ryukyu-ayu, which has a potential to prevent the fish from spawning because of their substratum adhesion. As for water depth and flow velocity no other reaches within the Yakugachi River satisfied the preferable conditions for spawning, and likewise spawning sites were not realized in the neighboring small stream, the Yanma River, in which the Ryukyu-ayu sometimes establishes inconsistent population. The Yakugachi River population of the Ryukyu-ayu has a role to be a donor within a meta-population structure and therefore should be given priority of conservation. In conclusion, the restoration of spawning site is effective to avoid the risk of local extinction. Cultivation of streambed by handworks using shovels and hoes is practical and recommended from the view point of cost performance. © 2009, Ecology and Civil Engineering Society. All rights reserved.
