In an attempt to fight rural poverty in Morogoro, some farmers have adopted fish farming technology and are operating fish ponds in groups. This study examined the efficacy of group-owned fish ponds in this part of Tanzania. A survey design was employed and data were collected from 217 respondents, randomly sampled from villages. Data were collected using questionnaire, participatory rural appraisal, researchers' observations and secondary information sources. A descriptive statistics method was used to report findings and data w ere validated by mean percentages. The results revealed that 16% of the farmers owned ponds in groups which constituted of 518 members in total; thus, they had significant impact on the prospects of aquaculture in the area. The idea of forming group ponds came from farmers own initiative and/or were sometimes suggested by the projects. The performance of most group-owned ponds was noted to be unsatisfactory in terms of the commitment shown by the members and the objectives that the projects had sought to achieve. This study recommends the following: First, working in groups should be encouraged for activities which are beyond individual capability or which reduce cost of operation when done collectively. Second, group should be formed on the basis of members' needs and common objectives. Most important here is that gain from group participation should outweigh costs in terms of self-sacrifice. Thirdly, forming groups of 5-15 members from own initiative should be encouraged as such size has proved to perform better than bigger ones. Fourthly, supportive services in form of training on leadership and business management, to improve group performance, should be provided.
