The Fish Oocyte: From Basic Studies to Biotechnological Applications [Paperback]

This book presents a comprehensive overview on egg production in fish, from the standpoint of the oocyte. It covers oocyte development, maturation, hydration and fertilization. The book places special emphasis on using state-of-the-art tools for discerning the ultra-structure of the follicle and genomic/proteomic tools to fully understand biological basis of fish reproduction.

Ultrastructural aspects of the ontogeny and differentiation of ray-finned fish ovarian follicles.- Molecular aspects of oocyte vitellogenesis in fish.- Zebrafish ovarian follicle transcriptome.- Proteomics analysis of the developing fish oocyte.- Oocyte zona pellucida proteins.- Maternal factors in fish oogenesis and embryonic development.- Gonadotropic regulation of oocyte development.- Sex steroid hormone receptors in fish ovaries.- Hormonal regulation of follicular atresia in teleost fish.- Ecotoxicological effects of endocrine disrupting compounds on fish reproduction.- Regulatory mechanisms of oocyte maturation and ovulation.- Physiological and molecular basis of fish oocyte hydration.- Fertilization and egg activation in fishes.- Low-temperature preservation of fish gonad cells and oocytes.- Promoting oocyte maturation, ovulation and spawning in farmed fish.

This book addresses the growing needs in deciphering the biological processes associated with fish reproduction, in view of the growth of aquaculture and the dwindling natural stocks of commercially important fish. It presents a comprehensive overview on egg production in fish, from the standpoint of the oocyte. With this view in mind, the book includes chapters on oocyte development (oogenesis), hormonal regulation and hormone receptors, formation of the egg envelopes, growth, accumulation of nutrients and maternal transcripts, maturation, hydration, ovulation and fertilization. A special emphasis is placed on using state-of-the-art tools including electron microscopy for discerning the ultra-structure of tlSŤ
