Report of the training programme on Essential Ecosystem Approach to Fisheries Management (EAFM): developing capacity in the EAFM, Chennai, India, 11-16 August, 2014

Participants were exposed to concepts and information about EAFM using a structured, participatory method of delivery. The learning strategy involved specifically designed exercises, using real examples, to consolidate learning. Daily monitoring and reviews were conducted together with pre-and post-course assessment.

Report of the NBFGR-BOBLME Indian mackerel genetics harmonisation training workshop, Kochi, India, 20-27 August, 2013

This workshop was held at the National Bureau of Fish Genetic Resources and followed on from the Indian mackerel Working group meeting in Colombo (28-29 May, 2012). Activities included; DNA extraction; PCR (Polymerase Chain Reaction) for microsatellites; genotyping microsatellites; data analysis; emerging technologies; and an action plan

Report of the catch assessment survey: fishery survey of Kyoga Lakes August 1990 - March 1991

This report presents the information obtained during catch assessment surveys made by the ADP Fishery Survey of Lake Kyoga and Lake Kwania between August 1990 and July 1991. It supersedes previous interim reports on these surveys. The Kyoga lakes had not been surveyed in a long time. Information on the state of the stocks was largely confined conclusions drawn from data collected along the southern shore of L.Kyoga proper. The effect of harmful/illegal gear types on the stocks was not documented. Part I provides a description of the survey. Part II comprises a review of the fishing strategies. Parts III and IV present the principal results obtained on L.Kyoga and L.Kwania. Part V presents a discussion of the main conclusions.

Morphometrics, length-weight relationship and condition of Rastrineobola argentea (Pellegrin 1904) in the Winam Gulf of Lake Victoria (Kenya)

Correlation between total length (TL), fork length (FL) and standard length (SL) of Raslrineobola argentea (pellegrin 1904) in the Winam Gulf of Lake Victoria indicate that FL = 0.92 TL - 0.74 and SL = 0.90 TL - 1.74. Length-weight relationship of log-transformed data shows that the slopes of the regression lines were 3.06 to 3.22 for juveniles, 2.70 to 3.05 for males and 3.24 to 3.71 for females. The slopes were significantly different between groups at at a =0.05. The Fulton's condition factor (K) was highest in December (1.019-1.073) and March/April (1.015-1.030) but lowest in June (1:00-1.025) for all stations. Significant differences between groups demands for the use of different growth models for juveniles, males and females especially for the von Bertalanffy growth equation which uses length-weight relationship. Observed cyclic viations in condition factor suggests two peak breeding seasons for this species in the Winam Gulf. The practical lmplications of these results in stock assessment using length-based fish stock assessment methods is briefly discussed.
