| dc.description.abstract | This study was carried out in the eastern part of Lake Tana (Fogera Woreda) covering both postrainy and dry seasons, from October 2015 to April 2016, with the objective to identify and assess species composition, relative abundance, socio-economic and marketing system of fish and fisheries in that locality. Field sampling, personal observation, structured questionnaire and interview were employed. Shannon diversity index was used to compare species diversity in all sampling sites between seasons. Correlation analysis and paired T- test were used to test species composition and abundance between seasons. Descriptive analysis and two ways ANOVA were used to analyze the collected data. Generally eight fish species were identified and Cyprinidae are the dominate one. Species composition of the fishes during the post- rainy and dry seasons was different. Mean Shannon diversity index showed highest H’ value (1.06) in dry than postrainy (1.04) season. The relative abundance score of species during the post-rainy and dry seasons was variable in all sampling sites and in dry season higher numbers of species were recorded (114). However, the most abundant species was Labeobarbus crassibarbus in weight (43.1) and Labeobarbus intermedius (46.7%) in number. Relation of fishing categories to boat and daily catch was analyzed by two way ANOVA and daily catch of fishers to the type of boat showed a significant difference (P<0.05). The fish price was influenced by marketing site, season and demand of customers. The Univariance analysis showed that there is significant difference (P<0.05) in price around landing site and Woreta city as well as in fasting and none fasting x periods. The finding of this thesis indicated that, training on fishing management, availability of infrastructure (road), access to credit and minimizing illegal fishing would promote effective fish resource utilization and sustainable market.
