ABSTRACT This study was conducted in north Gondar Alefa woreda. It is obvious that fishery resources, like other living resources, are limited. The population of the country in general and that of the study area is however continuously increasing. This implies that the imbalances between fish resources (the supply) and the population size (the demand) in the fish market have showed an increasing trend over time. Thus, to narrow down this imbalance and sustainably use the fish resource, there is a need to conserve, manage, and utilize effectively and efficiently. The general objective of the study was to analyze fish harvest practice and management system. In this study, both primary and secondary data were used. Primary data were collected through questionnaire survey. Besides the primary data, secondary data on fisheries, population and other variables were collected. The sample of 118 fishermen were selected randomly and interviewed. Both descriptive statistics and multiple linear regression analysis were done to answer the objectives. The results of the study are 100% of the fishermen are male, 95.7% fishermen are active age (30-65), not all seasons have equal chance to harvesting in the given year, 92.4% fishermen approved to need fish harvesting experience, fish harvest selling price per kg high 100 birr, moderate 60 birr and low 50 birr, and monthly income of the fishermen are mini.50 birr, max.505 birr and average 300 birr.
