| Research Abstract |
Relationship between stress and feeding-reproductive system in teleost fish was examined as a basis for aquaculture. The stress-related corticotropin-releasing hormone (CRH) was detected in many teleost fishes such as Japanese eel, red seabream, tiger puffer, sturgeon and medaka by immunohistochemistry. Furthermore, it is indicated that reciprocal connections exist between the CRH neurons and gonadotropin-releasing hormone (GnRH) neurons in the Japanese eel. It is also indicated that background color affects body color, feeding, somatic growth, plasma cortisol levels and hypothalamic CRH mRNA levels in the Japanese eel.
