Editorial: Neuroendocrine regulations in fish: role of environmental and internal factors.

This document is an editorial published in the journal Frontiers in Endocrinology. It discusses the role of environmental and internal factors in the neuroendocrine regulation of fish. The editorial highlights the importance of the brain-pituitary axis in controlling various physiological processes in fish, such as growth, reproduction, metabolism, and stress responses. It also mentions recent research findings on new components and mechanisms involved in endocrine regulation and plasticity in fish. The editorial introduces a research topic on neuroendocrine regulations in fish, which includes five original research articles covering different aspects of neuroendocrine regulation in fish. The articles explore the measurement of signaling molecules in fish tissues, the role of aromatases in zebrafish reproduction, the hormonal regulation of oocyte hydration in marine teleosts, the effects of cysteamine on growth and the GH/IGF axis in gilthead sea bream, and the role of somatostatin in regulating growth hormone secretion and reproductive hormone levels in tilapia. The editorial concludes by stating that the research topic provides valuable insights into the complex neuroendocrine mechanisms that regulate growth and reproduction in fish and hopes that it will contribute to the development of more effective strategies for promoting growth and reproductive success in fish populations.
