Research Abstract

We examined the effect of two different wavelengths-blue (peak at 465 nm) and -red (peak at 625nm) on the behavior, somatic growth and sexual gonadal differentiation of the young Japanese pufferfish,Takifugu rubripes. The light sources were used as LED with one wave length. Under the red light condition, the fry (one week after hatch) showed the strange behaviors that they moved to the edge of the water tank, gathered and picked at the wallwith the high aggressiveness. In contrast, under the blue light, they kept constant distance and swam apart from the water tank wall. Pufferfish bred by each wavelength has the gonadal sex identical to the genetic sex. As for the puffer bred by a red light, unevenness was confirmed to the total length after irradiation in comparison with natural light or blue light within one week, and the tendency continued afterwards. These results indicate that the color wavelength is one of the factors to decide the actions (aggression, escape, relief etc.) of the pufferfish larvae under the natural environment.
