Abstract

Koi fish (Cyprinus carpio L.) are a highly sought-after variant of the common carp, renowned for their unique and bold colorations. This thesis examines the significance of koi and common carp coloration from both cultural and scientific perspectives. From a cultural standpoint, the rich history and mythology surrounding the common carp in East Asia is explored through the discussion of art and literature. From a scientific standpoint, a detailed explanation of the underpinnings of coloration and pigmentation is provided by the analysis of optics, chromatophores, and pigments. Finally, this thesis proposes an experiment that combines these perspectives by studying coloration in Asagi koi through the manipulation of melanophores via magnetic fields and metal-ions to affect the blue coloration. Overall, this thesis provides a nuanced understanding of koi and common carp coloration through the holistic dissection of this multifaceted subject.
