“…Aquaculture is an important practice that has also been used as a solution to the problems generated by the overexploitation of fishing resources, requiring, however, the use of techniques that aim at practical and socio-environmental sustainability (Nascimento, Córdula, Benício, Oliveira, & Silva, 2015). Brazil has long been recognized as having ideal conditions for the development of shrimp farming as it possesses large areas of the coastal land, warm water temperatures year-round, an extensive agroindustrial base and an attractive domestic market (Cavalli et al, 2008). On the other hand, despite the dependence on an adequate water source, continental culture is an alternative that can generate income for local communities while it alleviates the pressure on coastal resources (Pinto et al, 2020), mitigating problems such as degradation of coastal waters, pond abandonment and destruction of mangrove forests (Galkanda-Arachchige, Roy, & Davis, 2020).…”

The present study aimed to correlate the influence of water quality, cultivation time, area, and density of ponds on the zootechnical performance of shrimp Litopenaeus vannamei in oligohaline waters. It was demonstrated that, under the conditions of this research, better control of temperature, pH and water alkalinity can be employed. Ammonia levels were within the normal range and correlated positively with the growth rate (ρ = 0.69859) and production (ρ = 0.66362) of the ponds. There was also a positive correlation between cultivation time and pond density with shrimp weight (ρ = 0.75305 and 0.68933) and pond productivity (ρ = 0.74763 and 0.79367, respectively). Negative correlations were observed between: I) pH with shrimp survival (ρ = -0.73238) and pond production (ρ = -0.68696); II) alkalinity and pond production (ρ = -0.66162). The results show that the cultivation of shrimp L. vannamei in oligohaline waters is viable and there is potential for increased productivity associated with better hydrological monitoring and use of higher density and cultivation time by some producers.
