Book (series)Technical reportPreliminary Results of the Hydroacoustic Survey conducted on Lake Kariba - September 2014
GCP/RAF/466/EC SmartFish Project
2014Also available in:
No results found.As a continuation of a hydroacoustic training in 2013 supported by SmartFish FAO, and in accordance with recommendations of the Fifth Technical Consultation on Development and Management of the Fisheries of Lake Kariba, SmartFish FAO supported a hydroacoustic survey in August 2014. The preliminary results of the survey that was undertaken to determine the standing biomass of Kapenta in Lake Kariba show that by adding the estimated biomasses of the basins and stratum, the estimated average standi ng biomass was 16,277 i.e. ± 9,730 tonnes. In order to ascertain any changes over time and to draw substantial conclusions, comparisons across time is necessary. A regular hydroacoustic survey programme will have to be established and the relationship between densities and environmental parameters should be assessed. -
Book (series)Technical reportReport of the Workshop to plan the 1999 R/V DR. FRIDTJOF NANSEN surveys in the northern CECAF area and the standardization of acoustic surveys in the region. Casablanca, Morocco, 18-22 October 1999. / Rapport de l'Atelier pour la planification des prospections du N/R DR.

No results found.A Workshop to plan the 1999 R/V DR. FRIDTJOF NANSEN surveys in the northern CECAF area and the standardization of acoustic surveys in the region was held in Casablanca, Morocco from 18 to 22 October 1999. This Workshop was a follow-up to the Workshop "A review of the surveys off Northwest Africa in the 1990s" held in Bergen in 1998 (FAO, 1998). The countries represented were the Gambia, Mauritania, Morocco and Senegal as well as Norway, Russia and FAO. The purpose of the Workshop was to plan the 1999 acoustic survey with the R/V DR. FRIDTJOF NANSEN off Northwest Africa in November-December 1999 and to discuss the standardization of acoustic surveys in the Northern CECAF area as well as following-up on other recommendations from the meeting in Bergen in 1998. The Workshop stressed the usefulness of the results from the DR. FRIDTJOF NANSEN surveys and strongly recommended that the surveys be continued. The Workshop considered that the use of the results for stock assessment could st ill be increased at a regional level and therefore recommended to establish a Working Group on assessment of small pelagic resources in the same region as covered by the DR. FRIDTJOF NANSEN surveys. The Working Group on Guidelines provided a first draft of the Guidelines for acoustic surveys in Northwest Africa. It was recommended that the Working Group should meet again before the next acoustic survey in the year 2000. -
Book (series)Technical studyManagement, co-management or no management? Major dilemmas in southern African freshwater fisheries. Part 2: Case studies. 2003
Also available in:
No results found.This report contains ten case studies which serve as background for a synthesis report published in FAO Fisheries Technical Paper 426/1. They have been conducted in five medium sized lakes in the Democratic Republic of Congo, Malawi, Zambia and Zimbabwe. Five of the case studies focus on biological and environmental effects while the remaining five are concerned with historical and sociological analysis. In different ways all the case studies focus on some of the following three featur es, relevant for the management of freshwater fisheries in the South Africa Development Community (SADC) region: – How has fishing effort developed in these lakes over the last 50 years? Despite a considerable increase in the total fishing effort in the region, the report demonstrates great variation in effort dynamics both in time and place. Most papers distinguish between changes related to the number of people and changes in technology and investment patterns and show that most of the increases in effort have been population-driven. Only in the case of Lake Malombe have changes in effort mainly been investment-driven. – What causes the changes in fishing effort?

DocumentNormative documentFAO Specifications and Evaluations for Agricultural Pesticides - Dazomet - Tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione
2001
2001Also available in:
No results found.FAO establishes and publishes specifications* for technical material and related formulations of agricultural pesticides, with the objective that these specifications may be used to provide an international point of reference against which products can be judged either for regulatory purposes or in commercial dealings. From 1999 onward, the development of FAO specifications follows the New Procedure, described first in the 5th edition of the "Manual on the development and use of FAO specifications for plant protection products" and later in the 1st edition of “Manual for Development and Use of FAO and WHO Specifications for Pesticides” (2002) - currently available as 3rd revision of the 1st edition (2016), which is available only on the internet through the FAO and WHO web sites. This document is the information on Dazomet - Tetrahydro-3,5-dimethyl-1,3,5-thiadiazine-2-thione. -

Also available in:
No results found.This issue of ASFA Magazine explores the evolving role of Aquatic Sciences and Fisheries Abstracts (ASFA) in the era of artificial intelligence (AI). It highlights how AI is reshaping the management and dissemination of fisheries and aquaculture information — from enhancing translation of technical terminology and improving data recording, to advancing the vision of a universal library. While embracing AI’s opportunities, ASFA remains attentive to the risks, ensuring that both its technologies and partners continue to evolve inclusively. The issue also features updates from ASFA partners, event highlights, and tributes, including an in memoriam for Jacqueline Prod’homme, a dedicated ASFA partner and advocate for knowledge sharing. -
