Feasibility study of organic fishing in a family production unit in Laranjeiras do Sul, Parana, Brazil

Abstract

The role of family farming has been gaining strength, driven by debates based on sustainable rural development, the generation of work and income, contributing to food security. Organic fish farming is an activity that can be developed by these farmers to promote sustainability. From this perspective, the objective of this work is to analyze the economic/financial, environmental and social viability of fish production in an organic system in excavated ponds based on a case study. The methodology adopted to achieve the objectives has an exploratory and descriptive character, combining bibliographical research on studies analyzing organic production in general and fish farming with case studies. Over a period of sixteen months, the production of organic fish in a polyculture system was monitored, using natural foods from the property. In the analyses, economic viability analysis techniques were used: Net Present Value (NPV); Discounted Payback (PB); Internal Rate of Return (IRR); and Profitability Index (IL). The amount invested in the nurseries was R$3,220.60. The estimated value for selling the fish was R$2,477.50. In the economic/financial viability analysis, the results indicate a return from the second production cycle. In the social dimension, occupied family labor stands out and whose greatest demand is during the implementation period, while this need is low in maintenance. In the environmental analysis, the results indicated the preservation of natural resources, with the reuse of food waste produced on the property and care with water and the generation of effluents.
