Abstract

This study aimed to characterize and analyze the sustainability indicators for fish farms in the city of Toledo, Paraná, Brazil, during the period September 2013 to March 2014. The research was divided into four stages: consultation of bibliographic sources, checklist inventory, case study and data analysis. The checklist was basically divided into 17 sections and 90 pertinent socioeconomic and environmental profile issues, which was applied to 25 active stakeholders involved with the activity of commercial fish farming ponds in the city of Toledo. The checklist has a number of questions pertinent to the theme of each section, where the interviewer attaches to issues the notes 0, 1, 2, 3, 4 or 5, which correspond respectively to 0, 20, 40, 60, 80 and 100% effectiveness as Answer Key proposed. Based on the responses of the interviewees has made the assessment and characterization of the projects, which resulted from: 0 to 20, 21 to 40, 41 to 60, 61 to 80 e 81 to 100%, the indexes may be defined as respectively "Critical", "Low", "Regular", "Good" or "Great" sustainability. From sections of the Checklist surveyed, 4 have generated sustainability indexes "Great", 11 "Good" and 2 "Regular". The global sustainability index obtained was 73%, a result that characterizes fish farms of Toledo, in general, "Good" social, economic and environmental sustainability. After the identification of loss-sections and the critical points, which represent 60% of total possible points, qualified as "Regular" or lower, applied the Summary Management Plan. The most deficient points located within the sections were restructured, thus setting, new strategies and practical solutions to increase the levels of sectoral and global sustainability of fish farms in the city. The application of public politics and more efficient extension services are suggested, making it necessary the implementation of technical advice to producers and development and building systems for wastewater treatment.
