No Thumbnail AvailableProjectProgramme / project reportReview of recycling of animal wastes as a source of nutrients for freshwater fishculture within an integrated livestock system 1983
Also available in:
No results found.The review describes in a comprehensive manner the state of knowledge in the utilization of animal wastes and their feeding to fish. A special attention is being paid to the mechanism of livestock waste recycling and an integrated approach involving livestock species whose manure can be utilized as a sole donor of nutrients for fish farming. The integration describes fish species consuming manures directly or through zooplankton, phytoplankton and macrophytes. A special chapter is allocated to feeding systems and procedures in nursery ponds using organic and chemical fertilizers as main sources of nutrients. The suitability of catfish for tropical and sub-tropical fish farming is examplified with particular respect to countries of Southeast Asia. The results of an impressive research carried cut in the sub-tropical part of USA are also presented. A chapter on carp farming emphasises those specific areas which involve feeding of livestock wastee as a sole source of nutrients for f ish via various eco-systems. The main objectives of integrated fish farming are highlighted with special reference to Pakistan and priorities areas of research undertaken by the PARC, UNDP/FAO Project PAK/80/019 - Coordinated National Programme for Livestock Feed Resources and Nutrition. The review presents comprehensive list of references. -

No results found.This report describes the potential for inland fish farming among the Caribbean Island States based on methods used in an earlier study (“A strategic assessment of the potential for freshwater fish farming in Latin America”, COPESCAL Technical Paper, No. 10, 1997) to estimate freshwater fish farming potential in Latin America. Four criteria were used to estimate potential for small-scale fish farming in ponds: water loss, potential for farm gate sales, soil and terrain suitability for ponds and availability of agriculture by-products as feed or fertilizer inputs. A fifth criterion was added in order to estimate potential for commercial fish farming: urban market potential. These criteria were weighted in different ways to make small-scale and commercial fish farming models on the basis of expert advice. Numbers of crops per year of Nile tilapia and common carp were predicted based on monthly climatic variables. By varying feeding levels and harvest sizes small-scale and commercial leve l outputs were simulated. Combining the small-scale and commercial models with the simulations of fish production provided overall suitability ratings for each 5 are minute grid (approximately 9 × 9 km). Field verifications were carried out in Jamaica and the Dominican Republic. The results suggest good potential for freshwater fish farming among many of the Caribbean Island States with relatively large areas rating very suitable or suitable for the combined criteria and with relatively high crops/year output of the species considered. The results of the field verifications indicated the importance of local knowledge for the interpretation of the predictions.
