SUMMARY:

Throughout its historical process, Brazilian shrimp farming, like that of other western countries, has achieved good rates of economic growth to the detriment of the negative socioenvironmental impacts generated. A pioneer in aquaculture practices, Asia has intensified the stocking density and reduced the area size of its crops with a focus on production sustainability. In this context, this study is divided into two chapters, with the first objective of analyzing the historical process of shrimp farming in Brazil, seeking to understand its adaptations and elucidating its development. For this, we analyze the complexity of the social organization and the technological advances that have occurred in the sector and, then, we adopt the developmental perspective of Amartya Sen, in secondary data, illustrating the activity and its impacts. The results obtained show that as shrimp became one of the main commodities in northeastern Brazil, there was an increase in the complexity of the sector's coordination. However, the negative environmental impacts generated by its cultivation and the political measures that deprived the Brazilian shrimp trade caused economic stagnation. In the second part, we aim to assess how the stocking density of crops and their land use is arranged in Brazil. We analyzed 116 shrimp farming cycles, which took place from 2016 to 2019 on five farms. We compared the duration of crops, the average weight of shrimp caught, the use of feed and the Feed Conversion Rate between crops with densities of 6 and 10 shrimp / m², area sizes 2.6 and 4.9 hectares and number of phases by independent T test. We found that more densely grown crops occur over larger areas and require a longer duration. Biphasic crops are the most densely populated, occupy a larger area of land and use more feed. In all the variables analyzed, the individual weight of the shrimp did not differ and the Feed Conversion Rate remained low. We conclude that the western method of raising shrimp still has difficulties in intensifying crops and reducing land use. The investment in two-phase crops allows optimizing the use of land, but more effective measures are necessary to maintain the growth of production without increasing the use of mangrove areas. And, finally, all actors related to the activity have claims regarding experienced deprivations and the desire to expand their freedoms as a synonym for development.
