Abstract��Abstract: The development of fish body color is an important issue in biological evolution, physiology and ecology. Plectropomus leopardus, a coral reef fish, shows significantly different body colors in different environments. In this paper, P. leopardus individuals with different colors were selected. The skin color, pigment distribution and melanin enzyme levels from different fish body parts were detected and analyzed. The results showed that many melanocytes and red pigment cells were distributed in the fish skin. The black individuals had a higher density of melanocytes, higher melanin content and lower melanin enzyme levels than the reds, while the reds had a higher density of red pigment cells, higher carotene and carotenoids, and higher melanin enzyme levels. The body color depth of P. leopardus was found to be related to the aggregation and dispersion of melanin particles and the levels of melanin-metabolizing enzymes. The brightness of body color was related to the content of red pigment cells and the contents of carotene and carotenoids. These experiments revealed the differences in pigment and enzyme levels between the red and black P. leopardus, and provided a theoretical basis for further study of mechanisms of body color variation.
