N. Messieh and published by Dartmouth, N.S. : Fisheries and Oceans, Canada. This book was released on 1989 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The identification of Atlantic herring stocks inhabiting both sides of the northern Atlantic has been the subject of numerous investigations for many years. In more recent years, the discreteness of the spring and autumn herring populations in the Gulf of St. Lawrence was established, a separation important for delineating proper fishery management units. Otolith characteristics, such as shape and first year's growth, were used in both the Gulf and Newfoundland regions, but the method used requires well-trained technicians and was criticized because of its subjectivity. A semi-automated microcomputer-based measuring system was developed for otolith measurements in the Gulf region to eliminate such subjectivity. The method uses a microscope with a drawing tube and a digitizer interfaced to a personal computer which analyzes the digitized otolith measurements using software packages. This report presents results using this system to separate herring spawning groups by otolith morphometrics.

Available in PDF, EPUB and Kindle. Book excerpt: Fish recruitment is a key process for maintaining sustainable fish populations. In the marine environment, fish recruitment is carried out in many different ways, all of which have different life history strategies. The objective of this book is to argue for greater linkages between basic and applied research on fisheries recruitment, and assessment and management of exploited fish stocks. Following an introductory chapter, this second edition of Fish Reproductive Biology is organized into 3 main sections: Biology, Population Dynamics and Recruitment Information Critical to Successful Assessment and Management Incorporation of Reproductive Biology and Recruitment Considerations into Management Advice and Strategies The authors collectively bring a wide range of diverse experience in areas of reproductive biology, fisheries oceanography, stock assessment, and management. Fully updated throughout, the book will be of great interest to a wide audience. It is useful as a textbook in graduate and undergraduate courses in fisheries biology, fisheries science, and fisheries resource management and will provide vital information for fish biologists, fisheries scientists and managers.

Available in PDF, EPUB and Kindle. Book excerpt: The Northeast Fisheries Science Center presents the section of "Age Determination Methods for Northwest Atlantic Species," on Atlantic herring, Clupea harengus, by L.M. Dery. Male and female herring grow at about the same rate and become sexually mature by age four or five. Scales were originally used to determine age of herring, but due to problems with scale loss during handling otoliths were then used.
