Book excerpt: The book Fish Endocrinology is an excellent book comprising eleven chapters which deal with the structural details and physiology of the various endocrine glands in Cyclostomes, Elasmobranchs and Teleosts. It is one of the best expositions for teachers and research workers interested in fish endocrinology all over the world. Latest references concerned, have been cited in this book and contributions of Indian workers have also been frequently incorporated. The illustrations include some beautiful microphotographs also. In the last chapter, Prospects for Future Research has been discussed which is of great value for the researchers. This book will definitely be an asset for the libraries.

Marra and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The corpuscles of Stannius [CS], small perirenal endocrine glands implicated in calcium and phosphate regulation in bony fishes, show interspecific variation in number, anatomical distribution, and fine structure. Whereas the more ancient members of Neopterygii possess a large number of CS scattered throughout the kidney proper, the Euteleostei demonstrate a reduction in number and a more posterior and independent distribution of the glandular bodies with respect to the renal tissue. Stanniocalcin [STC], the only active principle characterized to date from the CS, appears to be more widely distributed among the vertebrates than was previously believed. Our examination into STC of the more ancient Actinopterygii suggests that this hormone has undergone considerable evolutionary pressure at the level of the molecule and in tissue distribution. Molecular approaches reveal differences in the protein core, the primary transcript size, and perhaps glycosylation of the STC molecule between species. Evidence at the molecular level suggests that STC mRNA may be subject to posttranslational processing and that tissue-specific expression of the STC gene is possible. This finding is interesting in light of the recent identification of STC in many mammalian tissues. Further, molecular approaches utilized to examine one member of the Osteoglossomorpha, one of the most ancient of teleosts, provide preliminary evidence that multiple forms of STC molecules may be present in representative species. Multiple sequence alignments of piscine STC revealed highly conserved structural elements found also in mammals. However, our results suggest that the variation in CS number, distribution, and fine structure, and differences in the STC molecule among Actinopterygii may be a consequence of their evolutionary history.

Available in PDF, EPUB and Kindle. Book excerpt: Fish lives in environments with a wide variety of chemical characteristics (fresh, brackish and seawater, acidic, alkaline, soft and hard waters). From an osmoregulatory point of view, fish have developed several mechanisms to live in these different environments. Fish osmoregulation has always attracted considerable attention and in the last years several studies have increased our knowledge of this physiological process. In this book several specialists have analyzed and reviewed the new data published regarding fish osmoregulation. The chapters present an integrative synthesis of the different aspects of this field focusing on osmoregulation in specific environments or situations, function of osmoregulatory organs, general mechanisms and endocrine control. In addition, interactions of osmoregulatory mechanisms with the immune system, diet and metabolism were also reviewed. New emerging techniques to study osmoregulation has also been analysed.
