Book (series)Enhancing or restoring the productivity of natural populations of shellfish and other marine invertebrate resources 2003
Also available in:
No results found.A broad review is provided of factors relevant to enhancing populations of invertebrate resources and methods promoting their recovery by natural recruitment, restocking or habitat restoration. The review focuses on the biological, technical, environmental, economic and biological factors affecting the feasibility of restoring or enhancing productivity of commercially valuable local invertebrate populations. Three categories of enhancement activity are recognized: restoring or enhancing stocks b y conventional management methods, transplanting or seeding, and the use of juveniles produced from collectors in the wild or from hatcheries. Some guidelines are provided on issues related to enhancing recruitment, site selection, experimental closures, ecosystem considerations including predator control, as part of a stock management and enhancement programme. Ownership and co-management issues, and the necessary decisional rules for successful management are discussed, as well as how to recon cile the enhancement programme with other uses of the coastline. Spatial and geographical considerations are addressed, including allocation of areas for enhancement, rotational harvest schemes, use of refugia for protecting juveniles and the spawning stock, and the impact of the use of coastal zones for other human activities. -
Book (series)Sturgeon Hatchery Manual 2013
Also available in:
This Sturgeon Hatchery Manual includes the latest available scientific research findings and experiences and compiles advice given in earlier manuals and handbooks on sturgeon culture and reproduction practices. This document can be considered an update of the Sturgeon Breeding and Rearing Handbook (Chebanov, Galich and Chmyr, 2004), which was published in the Russian language. The Sturgeon Hatchery Manual was prepared in response to numerous requests for practical guidance on this s ubject from the Central Asian and Caucasus region to the Food and Agriculture Organization of the United Nations (FAO). This manual is targeted particularly at sturgeon farmers, sturgeon hatchery operators, hatchery technicians, and fisheries and aquaculture managers involved in sturgeon aquaculture development and the restocking and rehabilitation of sturgeon populations in the countries around the basins of the Black and Caspian seas. It aims to provide a practical handbook of mode rn sturgeon hatchery practices and management. The manual is available in the English, Russian and Turkish languages. The manual starts with a chapter on the taxonomy, biology, distribution and life histories of Azov-Black and Caspian Sea sturgeons. Subsequent chapters discuss the following aspects of sturgeon hatchery practices: hatchery design, collection and transportation of wild broodstock, broodstock management, spawning and gamete processing, fry and fingerling rearing, prod uction of live feeds, the technology of artificial reproduction, ecological- morphological and ethological-physiological express estimation of larval and fingerling (fry) viability, release of fingerlings into natural waterbodies, the formation of domesticated broodstock, basic sanitation and fish health measures, tagging, and early sexing and maturity determination in live sturgeons using ultrasound techniques. The manual also contains an extensive list of references, a list of Acip enseriformes and numerous figures, photographs and tables to support the guidance given on the various hatchery practices -
