This book was released on 2009-08-07 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Techniques and theory for processing otoliths from tropical marine fish have developed only recently due to an historic misconception that these organisms could not be aged. Otoliths are the most commonly used structures from which daily, seasonal or annual records of a fish’s environmental history are inferred, and are also used as indicators of migration patterns, home range, spatial distribution, stock structure and life history events. A large proportion of projects undertaken on tropical marine organisms involve removal and processing of calcified structures such as otoliths, statoliths or vertebrae to retrieve biological, biochemical or genetic information. Current techniques and principles have evolved rapidly and are under constant modification and these differ among laboratories, and more particularly among species and within life history stages. Tropical fish otoliths: Information for assessment, management and ecology is a comprehensive description of the current status of knowledge about otoliths in the tropics. This book has contributions from leading experts in the field, encompassing a tropical perspective on daily and annual ageing in fish and invertebrates, microchemistry, interpreting otolith microstructure and using it to back-calculate life history events, and includes a treatise on the significance of validating periodicity in otoliths.

This book was released on 2020-10-23 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ‘Aquatic Habitat Conservation in South America’ Symposium occurred during the XXI Brazilian Society of Ichthyology Meeting. The proceedings were published as a special issue in the Journal of Fish Biology (vol. 89, Number 1, June 2016). In this special issue, authors provided an analytical overview of problems faced by the conservation of fishes and aquatic habitats of South America. Habitat loss emerged as the greatest concern for all South American aquatic ecosystems, with a long list of causes related to unsustainable development models. Based on this finding, we would like to extend this topic to other continents, different climates, fauna and flora around the world. Our goal is to provide a comprehensive and multidisciplinary overview of variables that influence flora and fauna distributions and shape their ecological interactions within aquatic ecosystems

Download or read book Life history Characteristics and Fishery Dynamics of Red Drum Sciaenops Ocellatus in the North central Gulf of Mexico written by Corbin Frank Bennetts and published by . This book was released on 2018 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Red drum (Sciaenops ocellatus) are highly targeted recreationally in the Gulf of Mexico, and support a small commercial fishery in Mississippi. Despite their popularity, the stock is assessed using data limited approaches that necessitate accurate life history information. I estimated the year-specific and year-aggregated escapement rates for the Mississippi stock (years 2004 to 2015), which were sensitive to mortality estimation methods; year-aggregated estimates were 6.9 to 28.2 % depending on the method, but temporal patterns were consistent. I then addressed concerns with previously estimated life-history characteristics by describing the sex-specific growth and reproductive dynamics. The three-parameter von Bertalanffy growth function was the best candidate length-at-age model, with no significant difference in overall growth between sex-specific relationships, but females had a larger mean asymptotic length, and four candidate models showed significant sexual dimorphism. I described Red Drum as batch spawners, with 3.7 days between successive spawns during the spawning season (August and September). The age at 50% maturity was around age-3 y in both sexes, but spawning capability was not evident until around age-6 y. The carbon (delta C-13) and nitrogen (delta N-15) stable isotope composition of Red Drum muscle tissue was more enriched in carbon offshore and was significantly different with respect to reproductive phase. Mean and variance of delta N-15 and variance of delta C-13 was significantly different between fish

Download or read book Fishery Science written by Lee A. Fuiman and published by John Wiley & Sons. This book was released on 2009-02-12 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now clear that data based on the studies of fish eggs and larvae make a number of unique contributions to fishery science that are crucial for accurate assessment and management of fish populations, including those of commercially important fisheries. This valuable book demonstrates why fish eggs and larvae are important, how the characteristics of early life stages require a somewhat different research approach and how information on early life stages can be applied and interpreted to yield unique insights into fish populations. The editors of Fishery Science have drawn together an extremely useful and well-written book with contributions from internationally respected researchers from North America, Asia and Europe. Chapters include a discussion of the unique nature of early life stages, age and growth, mortality, recruitment, populations analysis, habitats, human impacts and management. A carefully selected set of case studies demonstrates several specific applications of early life history information to a number of fishery problems. Fishery Science was designed to complement existing textbooks and is an essential purchase for all fisheries students and professionals, and for biologists working on the early life stages of fish. This exciting book is also of great value to ecologists, marine, freshwater and environmental scientists, populations biologists and oceanographers. All libraries in universities and research establishments where biological and fishery science are studied and taught should have copies of this book available on their shelves.

Download or read book Recruitment of Stocked Juvenile Red Drum Sciaenops Ocellatus to the Adult Population in South Carolina written by Joy Gerhard and published by . This book was released on 2010 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Red drum (Sciaenops ocellatus) is a popular food and recreational fishery species along the southeast U.S. and Gulf of Mexico coasts. Although contribution of stocked fish to the wild population in South Carolina has been measured immediately following stocking up to age two, evaluation of stocked fish recruitment to the adult population has not yet been examined and therefore is the focus of this research. Small juveniles (~30 mm TL) were stocked in the Ashley and Wando Rivers of Charleston Harbor in 1999 - 2002 by the South Carolina Department of Natural Resources (SCDNR). Five years after initial stocking (2004 - 2008), adults were sampled via longline nearshore of four major South Carolina estuaries, and tissue samples were collected for genetic analysis. Genotypes of sampled fish were compared to those of broodstock and it was determined that small stocked juveniles do recruit to the adult stock in South Carolina, with a highly localized contribution near Charleston Harbor. Contribution of the identified stocked fish was estimated via several different methods. Contribution to the stocked year classes in particular were estimated by using length data as well as otolith-based age data collected before and during the sampling period. The percentage of the Charleston Harbor adult population identified as stocked fish from three stocked year classes ranged from 5.8% to 66.0% with the most preferred method, using age-length keys, yielding a contribution estimate of 34.9%. Such a high contribution has the potential to cause deleterious genetic and reproductive effects, though the broodstock husbandry and stocking protocol used by SCDNR is designed to minimalize these effects. Additionally, contribution of this magnitude might allow stocked fish to be used as biomarkers to gain a better understanding of the basic population parameters of adults in South Carolina for management.
