Book (stand-alone)Manual on catfish hatchery and production. A guide for small to medium scale hatchery and farm producers in Nigeria 2006

No results found.The Aquaculture and Inland Fisheries Project, (AIFP) otherwise known as AnnexII of the Nigerian Special Programme for Food Security (NSPFS) was operational between 18 July 2003 and 30 June 2006 for 35 months. The AIFP’s objectives included compiling an inventory and data base of inland water bodies, fish farms and feed mills, providing technical assistance to private fish farmers and assisting artisanal fisherman in community-based management of inland waters. A good linkage was forged between p rivate fish hatcheries and the stocking of lakes for increased fish production. Efforts were also made towards reduction of post harvest loss of fish through improved fish smoking demonstrations. The project was successful in creating increased public awareness on aquaculture and fisheries bringing them to become national development priorities. -
Book (series)Capture-based aquaculture. Global overview. 2008
Also available in:
Aquaculture is a diverse and multibillion dollar economic sector that uses various strategies for fish production. The harvesting of wild individuals from very early stages in the life cycle to large mature adults for on-growing under confined and controlled conditions is one of these strategies. This system, referred to as capture-based aquaculture, is practised throughout the world using a variety of marine and freshwater species with important environmental, social and economic implications. The need to evaluate the sustainability of this farming practice in light of its economic viability, the wise use of natural resources and socio-environmental impacts as a whole has been extensively discussed at national, regional and international levels. In 2004, the Food and Agriculture Organization of the United Nations (FAO) launched a project entitled “Towards sustainable aquaculture – selected issues and guidelines” funded by the Government of Japan which included a thematic component o n the use of wild fish and fishery resources for aquaculture production. The objective is to produce a set of technical guidelines that would assist policy-makers in developing informed and appropriate capture-based aquaculture regulations that would take into account the use and conservation of the aquatic resources exploited. This publication contains technical information prepared in support of and background material for the “FAO international workshop on technical guidelines for the respo nsible use of wild fish and fishery resources for capture-based aquaculture production” held in Viet Nam in October 2007. The first draft of the technical guidelines on capture-based aquaculture was produced during this meeting. This publication contains two parts. Part 1 consists of two reviews on (a) environmental and biodiversity and (b) social and economic impacts of capture-based aquaculture and Part 2 consists of eleven species review papers. Both marine and freshwater examples have been r eviewed and include finfish (mullet, bluefin tuna, European eel, cod, grouper, yellowtail, Clarias catfish, Indian major carps, and snakehead and Pangasiid catfish), crustaceans (mud crab) and molluscs (oyster). -
Book (series)The hatchery culture of bivalves: a practical manual 2004Bivalve mollusc culture is an important and rapidly expanding sector of world aquaculture production, representing approximately 20% of this output at 14 million tonnes in 2000. The majority of production is from natural populations although increasingly stocks are approaching or have exceeded maximum sustainable yields. Enhancement of stocks through the capture and relaying of natural seed in both extensive and intensive forms of culture is common practice worldwide but the reliability of natur al recruitment can never be guaranteed and conflicts over the use of the coastal zone are becoming ever more pressing. A solution to meeting the seed requirements of the bivalve industry, applicable to the production of high unit value species such as clams, oysters and scallops, is hatchery culture. The production of seed through hatchery propagation accounts at the present time for only a small percentage of the total seed requirement but it is likely to become increasingly important as work continues to produce genetically selected strains with desirable characteristics suited to particular conditions. The advent of bivalve hatcheries was in the 1960s in Europe and the U.S. Since those early pioneering days knowledge of the biological requirements of the various species that predominate in worldwide aquaculture production and the technology by which to produce them has and continues to improve. This manual brings together the current state of knowledge in describing the v arious aspects of hatchery culture and production from acquisition of broodstock to the stage at which the seed are of sufficient size to transfer to sea-based growout. Focus is on intensive methodology in purpose built hatchery facilities rather than on more extensive methods of seed production in land-based pond systems. This manual is not intended as a scientific treatise on the subject. Rather, it is practical in nature providing the reader with an insight into what is required in the w ay of resources and details of how to handle and manage the various life history stages of bivalves in the hatchery production cycle.
