Change in stable nitrogen isotope ratio in the muscle tissue of a migratory goby, Rhinogobius sp., in a natural setting
TLDR
Results from the field show that growth is primarily responsible for isotopic changes in fish muscle and highlight the need to examine the role of metabolic turnover using slow-growing fish.

Species diversity in native fish community in Japan: comparison between non-invaded and invaded ponds by exotic fish
TLDR
The results suggest that invasions by the two exotic fish caused serious depletion of native fish communities, although another process can also be considered, that is, that ponds with poornative fish communities were prone to colonization by these exotic fish.

Distribution of the freshwater fishes of Japan: an historical overview
TLDR
To conserve endangered species and declining communities of Japanese freshwater fishes, it is needed to clarify the characteristics of their original habitats and the effects of developing paddy fields, from both the ecological and historical points of view.

Retroposition of the AFC Family of SINEs (Short Interspersed Repetitive Elements) Before and During the Adaptive Radiation of Cichlid Fishes in Lake Malawi and Related Inferences About Phylogeny
TLDR
It is suggested that incomplete lineage sorting and/or interspecific hybridization might have occurred or be occurring among the species in this group, which might potentially cause misinterpretation of phylogenetic data, in particular when a single-locus marker, such as a sequence in the mitochondrial DNA, is used for analysis.

Trophic polymorphism in introduced bluegill in Japan
TLDR
It is demonstrated that bluegill (Lepomis macrochirus) introduced from their native North American source to Lake Biwa in Japan showed considerable trophic and morphological variations (morphs), which is a unique example of Trophic polymorphism occurring in an introduced fish species in a species-rich fish community.

Difference in the hypoxia tolerance of the round crucian carp and largemouth bass: implications for physiological refugia in the macrophyte zone
TLDR
The hypoxia tolerance of larval and juvenile round crucian carp and largemouth bass was determined using respirometry to examine the potential of hypoxic areas in the macrophyte zone as physiological refugia for round crucifixian carp.

Effects of summer drawdown on cyprinid fish larvae in Lake Biwa, Japan
TLDR
The artificial reductions in water level probably resulted in a significant decrease in the volume of shallow water in the lake and may be linked to the drastic decline in these cyprinid fishes.

Food habits and foraging behaviour of benthivorous cichlid fishes in Lake Tanganyika

TLDR
A super-abundance of shrimps may allow the coexistence of shrimp-eaters with different foraging techniques, and furthermore, their coexistence itself may promote cooperative group-foraging among them.

Effect of rainfall on the long‐term population dynamics of the aquatic firefly Luciola cruciata
  • M. Yuma
  • Environmental Science
  • 1 September 2007
TLDR
Long‐term observations of adult populations of the aquatic Genji firefly, Luciola cruciata, were conducted using a simple flash counting method from 1975 to 2006, indicating the influence of large‐scale environmental phenomena such as weather conditions on population dynamics.

Deterioration of cichlid habitat by increased sedimentation in the rocky littoral zone of Lake Malawi
TLDR
Results showed that these cichlids preferred sediment-free bottom and that the sedimentation causes deterioration of their habitats, which is needed in the management of these most diverse freshwater fish communities.
