Available in PDF, EPUB and Kindle. Book excerpt: This book breaks new ground with the integration of geography, oceanography, plankton and benthic biology, as well as fish, to present a comprehensive account of the ecology of the tropical ocean. Proceeding from a description of the geomorphology, sediments, and vegetation of tropical continental shelves and the oceanography of tropical regions, the authors describe the benthos, plankton, and fish communities of tropical seas. An examination of the production of plant and animal life in tropical oceans is presented together with the numerical population biology of fish and invertebrates.

Download or read book Fish Population Dynamics written by J. A. Gulland and published by . This book was released on 1988-11-17 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new edition provides updated information on population dynamics of major food fishes, and reviews the various methods used to study quantitative impacts of fishing on fish stocks. Contributors provide an historical background of the subject, then go on to cover current theories and methods of stock assessment, how these theories and methods have been applied in practice, and the effects of fisheries management on fish populations. They discuss length-based methods of stock assessment, multi-species fisheries, and provide data on fish populations in the North Atlantic, the Irish Sea, off Australia, Southeast Asia, and other regions. Completely revised and updated, including several new chapters.

Download or read book Small scale Aquaponic Food Production written by Christopher Somerville and published by Fao. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical paper begins by introducing the concept of aquaponics, including a brief history of its development and its place within the larger category of soil-less culture and modern agriculture. It discusses the main theoretical concepts of aquaponics, including the nitrogen cycle and the nitrification process, the role of bacteria, and the concept of balancing an aquaponic unit. It then moves on to cover important considerations of water quality parameters, water testing, and water sourcing for aquaponics, as well as methods and theories of unit design, including the three main methods of aquaponic systems: media beds, nutrient film technique, and deep water culture. The publication discusses in detail the three groups of living organisms (bacteria, plants and fish) that make up the aquaponic ecosystem. It also presents management strategies and troubleshooting practices, as well as related topics, specifically highlighting local and sustainable sources of aquaponic inputs. The publication also includes nine appendixes that present other key topics: ideal conditions for common plants grown in aquaponics; chemical and biological controls of common pests and diseases including a compatible planting guide; common fish diseases and related symptoms, causes and remedies; tools to calculate the ammonia produced and biofiltration media required for a certain fish stocking density and amount of fish feed added; production of homemade fish feed; guidelines and considerations for establishing aquaponic units; a cost-benefit analysis of a small-scale, media bed aquaponic unit; a comprehensive guide to building small-scale versions of each of the three aquaponic methods; and a brief summary of this publication designed as a supplemental handout for outreach, extension and education.

Download or read book The World of Sea Cucumbers written by Annie Mercier and published by Elsevier. This book was released on 2023-11-10 with total page 856 pages. Available in PDF, EPUB and Kindle. Book excerpt: The World of Sea Cucumbers: Challenges, Advances, and Innovations provides broad coverage of sea cucumber biology, ecology, fisheries, aquaculture, and trade while also bringing forward novel cultural, socioeconomic and scientific topics related to commercial and non-commercial species worldwide. Written by international experts in their respective fields, the book offers a unique outlook into the fascinating world of sea cucumbers while also providing valuable information to various stakeholders and researchers. Commercial fisheries and aquaculture programs are addressed, especially as they relate to emerging species, but the book also covers novel, understudied or lesser-known biological, ecological, and commercial aspects. The involvement of Indigenous peoples and minorities in various community-level initiatives and on the cultural significance/impact of sea cucumbers in many regions are also examined. Finally, breakthroughs and emerging biotechnologies centered on sea cucumbers are presented. Brings together a network of experts covering broad sea cucumber topics, from basic biology and commercial trade to socioeconomic value and novel biotechnologies Offers worldwide coverage, including Asia, the Indo-Pacific, Africa, Northern Europe, North and South America, and the poles Raises global awareness on little-known facts of sea cucumber importance

Download or read book Elasmobranch Biodiversity Conservation and Management written by Sarah L. Fowler and published by IUCN. This book was released on 2002 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Darwin Elasmobranch Biodiversity Conservation and Management project in Sabah held a three-day international seminar that included a one-day workshop in order to highlight freshwater and coastal elasmobranch conservation issues in the region and worldwide, to disseminate the result of the project to other Malaysian states and countries, and to raise awareness of the importance of considering aspects of elasmobranch biodiversity in the context of nature conservation, commercial fisheries management, and for subsistence fishing communities. These proceedings contain numerous peer-reviewed papers originally presented at the seminar, which cover a wide range of topics, with particular reference to species from freshwater and estuarine habitats. The workshop served to develop recommendations concerning the future prospects of elasmobranch fisheries, biodiversity, conservation and management. This paper records those conclusions, which highlight the importance of elasmobranchs as top marine predators and keystone species, noting that permanent damage to shark and ray populations are likely to have serious and unexpected negative consequences for commercial and subsistence yields of other important fish stocks.
