The color tone of cultured red sea bream <i>Pagrus major</i> quickly becomes dark immediately after death, which reduces the commercial value of the fish. The effects of several temperature treatments and different concentrations of K<sup>+</sup> on the skin color of red sea bream and on melanosome movements in melanophores were investigated to prevent darkening of the skin color. <br>Soaking solutions containing 300mmol/ι K<sup>+</sup> induced the aggregation of melanosomes in the skin and prevented skin darkening. The aggregation effects were enhanced by storage at low temperatures, such as 0 and 4°C. It is concluded that soaking in solutions containing K<sup>+</sup> followed by storage at low temperatures is useful to maintain the vivid skin color of the cultured red sea bream.
