No results found.The FAO Expert Workshop on Indicators for Assessing the Contribution of Small-Scale Aquaculture (SSA) to Sustainable Rural Development (SRD), held from 6 to 8 August 2009, in Tagaytay City, the Philippines, and participated by a total of twenty three experts, was convened to achieve the following: (i) present the outcomes (results and analysis) of the case studies which pilot-tested the Nha Trang SSA contribution indicators using various types of SSA in the Philippines, Thailand and Viet Nam; (ii) present the cross-country analysis and synthesis based on the outcomes of the pilot tests; (iii) refine and validate the indicators and evaluate their robustness, replicability and applicability in helping measure SSA sector performance for wider adoption and (iv) draw up a list of recommendations to further support (.e.g. appropriate interventions, priority setting and resource allocation) to the SSA sub-sector of sustainable aquaculture and rural development programmes based on a broad u nderstanding of sector performance (as measured by indicators) as well as risks and threats. The expert workshop carefully looked at each of the 14 Nha Trang SSA indicators and its applicability to the wide spectrum of SSA systems, based on the outcomes of the three country pilot tests covering seven SSA types, and the cross-country analysis/regional synthesis. The expert workshop brought forward a number of issues/concerns with respect to methodology, direct attribution to SRD, source of d ata and constraints in data collection. Recommendations were provided on which of the 14 Nha Trang indicators need further refining, merging, and/or deleting from the list, additional indicators as well as some aspects of the methodology used. A number of general recommendations was drawn for follow-up work in terms of SSA systems and scaling up, special research topics/studies including a number of issues of wider concern, e.g., biosecurity and food safety, natural disasters and risks, st atistical considerations, indicators for assessing impacts of SSA to the environment and biodiversity and networking. -
Book (series)Use of algae and aquatic macrophytes as feed in small-scale aquaculture - a review 2009
Also available in:
No results found.This paper presents a global review on the use of aquatic macrophytes as feed for farmed fish, with particular reference to their current and potential use by small-scale farmers. The review is organized under four major divisions of aquatic macrophytes: algae, floating macrophytes, submerged macrophytes and emergent macrophytes. Under floating macrophytes, Azolla, duckweeds and water hyacinths are discussed separately; the remaining floating macrophytes are grouped together and are reviewed as ‘other floating macrophytes’. The review covers aspects concerned with the production and/or cultivation techniques and use of the macrophytes in their fresh and/or processed state as feed for farmed fish. Efficiency of feeding is evaluated by presenting data on growth, food conversion and digestibility of target fish species. Results of laboratory and field trials and on-farm utilization of macrophytes by farmed fish species are presented. The paper provides information on the different process ing methods employed (including composting and fermentation) and results obtained to date with different species throughout the world with particular reference to Asia. Finally, it gives information on the proximate and chemical composition of most commonly occurring macrophytes, their classification and their geographical distribution and environmental requirements. -
Book (series)Small-scale rainbow trout farming 2011This technical paper is a basic guide to the starting and successful practice of small-scale trout farming. It summarizes all the technical information that it is important to know for small-scale trout production. In mountainous regions, where water resources could support profitable trout farming, protection of the environment is also important. Therefore, this technical paper contains sections with information about the basics of efficient treatment of trout farm effluents. The concept of this technical paper is to guide the reader through the necessary technical information, related practical solutions and the steps of preparation of both investment in and day-to-day operation of a small-scale rainbow trout farm. In order to satisfy interest for specific details, a glossary has been compiled and tables and annexes attached. Explanations are short but together with their illustrations they should be informative. Hence, it is hoped that this combination will f acilitate easy understanding and learning of rainbow trout farming.
