In this study, we determined the color vision and spectral sensitivity of pointhead flounder, slime flounder, and red halibut by recording electrophysiological S-potentials from isolated retinas; this basic data was collected to aid the selection of

The visual acuity, visual axis and visual accommodation of pointhead flounder, slime flounder, and red halibut were determined to obtain basic knowledge for developing appropriate fishing gear and fishing methods for sustainable fisheries. Each of th

A field experiment was conducted in the Matsumae area of Hokkaido, Japan, during June and July 2002, to investigate the effects of different entrance designs on the catch efficiency of fish traps by fishing with commercial traps (entrance inclination

– The continuous observation of salmon behaviour in some wild environments can be extremely difficult. We recorded spawning behaviour of female chum salmon (Oncorhynchus keta) in the field simultaneously using visual observation and fish-borne data

Fish catch efficiency can vary with the design of the trap entrance. To clarify how trap entrance design affects catch efficiency, the responses of fish to different trap entrance designs with different inclination angles or funnel lengths were obser

In this experiment, we used sound stimuli of different durations to demonstrate that the auditory evoked potential (AEP) of fishes was contaminated with microphonic potential. We demonstrated that the AEP contained a component that had double the fre

In this study, the visual acuity, visual accommodation, and spectral sensitivity of the elkhorn sculpin were determined. The elkhorn sculpin Alcichthys alcicornis is a typical groundfish that has conspicuously large eyes. They are caught by bottom gi

We have developed a system called net shape and loading analysis system (NaLA) for determining fishing net configuration and load analysis, and have used it to estimate the dynamic behaviour of actual fishing gear, such as gill nets and aquaculture f

In this study, the auditory thresholds for juvenile Japanese sand lance Ammodytes personatus were measured based on its auditory brainstem response (ABR). The amplitude of the ABR waveforms to a sound stimulus were larger than that of the electric ba
