    Exploiting Dairy Production Potential in Sri Lanka - TCP SRL 3501 2018
    Also available in:
    No results found.

    Small-scale dairying plays a crucial role in the livelihoods and food security of many smallholders and rural communities in Sri Lanka. Dairy products are essential to providing low-cost and high quality protein, minerals and vitamins, and great potential exists for the development of the dairy industry. However, domestic production falls short of its potential and much of the demand for dairy products is met by importing milk powder. Dairy production costs are relatively low for farmers, but development of the industry is hindered by a shortage of steady supplies of feed. Therefore, this project aimed to increase milk production by improving feeding and management techniques and increasing the feed base.

    Manual on hatchery production of seabass and gilthead seabream- Volume 1 1999
    Also available in:
    No results found.

    Seabass and gilthead seabream are the two marine fish species, which have characterized the development of marine aquaculture in the Mediterranean basin in the last two decades. The substantial increase in production levels of these two high value species has been possible thanks to the progressive improvement in the technologies involved in the production of fry in hatcheries. As a result of this technological progress more than one hundred hatcheries have been built in the Mediterranean basin, working on these and other similar species. At present the farmed production of these two species that is derived from hatchery produced fry is far greater than the supply coming from the wild. The development of these techniques, based originally on Japanese hatchery techniques has followed its own evolution and has resulted in what could be called a Mediterranean hatchery technology that is still evolving to provide higher quality animals and to reduce cost of production. This is a dynamic sector but it can be judged that it has reached a level of maturity that merits the production of a manual for hatchery personnel. The preparation of the manual has taken several years, also due to the progress of the sector that led to substantial revisions of sections. This has lengthened its preparation beyond what was originally expected. The manual is not intended to be the final word on hatchery production but rather a publication on how the industry produces in the late nineties. We prefe rred to include proven procedures rather than orient this publication to research on hatchery produced fry, as there is plenty of academic literature on this subject. The manual has been divided in two volumes, with this first one divided in three parts. The first part dealing with the historical background which has led to the present status of this practice, and a discussion of the main factors that affect fish seed production.

    Manual on hatchery production of seabass and gilthead seabream - Volume 2 2005

    Seabass and gilthead seabream are the two marine fish species which have characterized the development of marine aquaculture in the Mediterranean basin in the last three decades. The substantial increase in production levels of these two species, initially of very high value, has been possible thanks to the progressive improvement in the technologies involved in the production of fry in hatcheries. As a result of this technological progress more than one hundred hatcheries have been bu ilt in the Mediterranean basin, working on these and other similar species. At present the farmed production of these two species that is derived from hatchery produced fry is far greater than the supply coming from capture fisheries. The development of these techniques, based originally on Japanese hatchery techniques, has followed its own evolution and has resulted in what could be called a Mediterranean hatchery technology that is still evolving to provide higher quality animals and to reduce the costs of production. This is a dynamic sector but it can be judged that it has reached a level of maturity that merits the production of a manual for hatchery personnel that could be also of interest in parts of the world other than the Mediterranean. The preparation of the manual has taken several years, also due to the progress of the sector that led to substantial revisions of sections. The manual is not intended to be a final word in hatchery design and operation but rather a publication to document how the industry produces. The authors have preferred to include proven procedures and designs rather than to orient this publication to research hatcheries that are not yet the standard of the sector. The manual has been divided in two volumes, of which the first one was finalized in year 2000, and which covered historical background, biology and life history of the two species and especially hatchery production procedures. This second volume is div ided in four parts.
