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 Dispersal Fishing and the Conservation of Marine Species written by Malin La Farge Pinsky and published by Stanford University. This book was released on 2011 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: A central goal of ecology is to understand the forces driving the distribution and abundance of organisms. However, understanding the population dynamics of high-dispersal species, their conservation, and the connections between population dynamics and evolution remains difficult. It is in this context that marine organisms provide a particularly intriguing and challenging study system. Their population dynamics are often highly stochastic, most species have a great ability to disperse, and as the last group of wild species exploited commercially, their ecology and evolution can be strongly influenced by human behavior. By using population genetics, modeling, and meta-analysis, this thesis investigates the spatial ecology of reef fish and the causes and evolutionary consequences of global fisheries collapse. One of the first challenges in understanding spatial population dynamics is obtaining accurate measurements of dispersal abilities. This has been especially difficult for marine species with pelagic larvae. In Chapter 1, I apply a new approach to measuring single-generation dispersal kernels in Clark's anemonefish (Amphiprion clarkii) in the central Philippines. After developing two methods for measuring the strength of local genetic drift, my results suggest that larval dispersal kernels in A. clarkii had a spread near 11 km (4-27 km). This study shows that ecologically relevant larval dispersal can be estimated with widely available genetic methods when effective density is measured carefully through cohort sampling and ecological censuses. In Chapter 2, I use dispersal kernels to develop a model for population openness. Openness refers to the degree to which populations are replenished by immigrants or by local production, a factor that has strong implications for population dynamics, species interactions, and response to exploitation. It is also a population trait that has been increasingly measured empirically, though we have until now lacked theory for predicting population openness. I show that considering habitat isolation elegantly explains the existence of surprisingly closed populations in high dispersal species, and that relatively closed populations are expected when patch spacing is more than twice the standard deviation of a species' dispersal kernel. In addition, empirical scales of habitat patchiness on coral reefs are sufficient to create both largely open and largely closed populations. We predict that habitat patchiness has strong control over population replenishment pathways for a wide range of marine and terrestrial species with a highly dispersive life stage. While the first tow chapters have strong implications for the design of regional marine protected areas, I turn to global conservation questions in Chapters 3 and 4. I first ask which marine fishes are most vulnerable to human impacts. Surveys of terrestrial species have suggested that large-bodied species and top predators are the most at risk, but there has been no global test of this hypothesis in the sea. Contrary to expectations, two datasets compiled from around the world suggest that up to twice as many fisheries for small, low trophic level species have collapsed as compared to those for large predators. I then show that collapsed and overfished species have lower genetic diversity than their close relatives. While the ecological and ecosystem impacts of harvesting wild populations have long been recognized, it has been controversial how widespread evolutionary impacts are. Using a meta-analytical approach across 37 taxonomically paired comparisons, I find on average 19% fewer alleles per locus in overfished species, but little difference in heterozygosity. I confirm with simulations that these results are consistent with a recent population bottleneck. These results suggest that the genetic impacts of overharvest are widespread, even among abundant species. A loss of allelic richness has implications for the long-term evolutionary potential of species.
Download or read book The Larvae of Indo Pacific Coastal Fishes written by Jeffrey Leis and published by BRILL. This book was released on 2021-10-01 with total page 870 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume in the Fauna Malesiana book series gives an extensive overview of the larval development of 124 families of fishes, many of them of importance for both fishery and from ecological perspectives. The families that are described originate from the center of global marine biodiversity: the tropical Indo-Pacific Oceans, a region rich in coral reefs, as well as mangrove, estuarine, and coastal shelf habitats. The identification guide not only documents the ontogeny of these fishes but also provides the means to identify these extraordinarily diverse larvae to the level of family. The book offers a wealth of instructive and detailed figures and illustrations (219 plates, each consisting of approximately 4 figures) for enabling the identification of these families and their larval specialization.

This book was released on 2016-06-30 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintaining ideal fish health and production, both of farmed and wild fish populations, requires continuous infrastructural and process upgrades to avoid significant losses as well as to facilitate seafood safety. Aquaculture is multidisciplinary in nature, combining knowledge from biology, veterinary medicine and food technology. Practical Notions on Fish Health and Production brings an integrated approach concerning practical aspects of ichthyology, fish health and aquaculture systems. The textbook will give readers a better understanding of issues related to the management of fish health and production, seafood processing, security, quality and safety. The book is organized in three sections which cover 1) general aspects of fish biology and development, 2) fish diseases and veterinary medicine, and 3) aquaculture and marine food supply chain management. Practical Notions on Fish Health and Production is an essential text for students, food industry professionals and novice fish farmers undertaking courses or training programs in veterinary medicine, aquaculture, and marine food processing systems.

Download or read book Emerging Sustainable Aquaculture Innovations in Africa written by Ndakalimwe Naftal Gabriel and published by Springer Nature. This book was released on 2023-05-11 with total page 545 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book presents the emerging sustainable innovations in all areas of aquaculture in Africa with a view to create an opportunity whereby scientific outputs and recommendations can be endorsed for improved aquaculture outputs towards poverty alleviation and food security on the continent. Food insecurity and poverty are some of the challenges faced on the African continent. These challenges are further exacerbated by the growing human population and the impacts of climate change. Today, aquaculture has become one of the fastest food producing sectors in the world, with the potential to contribute significantly to food security and poverty alleviation in developing countries. In Africa, aquaculture is at an infant stage, however, many African countries have recognized the potential roles of aquaculture in food security, poverty alleviation and conservation of aquatic resources through their commitment to achieve the United Nation Sustainable Development Goals. The book reviews and synthesize research work from these thematic areas across Africa and provide a unique perspective on the emerging aquaculture innovations and illustrate how aquaculture practices could be feasible and cost effective while promoting social and environmental sustainability. The book also draws from global discussions on sustainable aquaculture practices and provides recommendations on what is feasible for Africa. This book is a great tool for the university students, scholars, aquaculture farmers, investors, and policymakers to understand the scientific based sustainable aquaculture innovations from an African perspective. This book is focused on SDG 2 and SDG 14.
