摘要

The synbiotic system improves the water quality and provides a complementary source of food for the shrimp. However, as it is an intensive system, there is an accumulation of organic matter and inorganic nitrogen, which can be used by species of different trophic levels. This work aims to evaluate the effect of the synbiotic on the production of the shrimp Penaeus vannamei, the oyster Crassostreia virginica, and the macroalga Ulva lactuca and provide economic insights comparing the benefits and costs of monoculture and IMTA. A shrimp nursery was carried out over 35 days in 0.06 m3 tanks with constant aeration and artificial lighting. There were four treatments, S: shrimp culture in a synbiotic; SO: shrimp culture integrated with oyster in a synbiotic; SOMsy: shrimp culture integrated with oyster and macroalgae in a synbiotic; SOMcw: shrimp, oyster, and macroalgae culture in clear water. As a result, the use of the synbiotic resulted in minimal water renewal compared to the SOMcw treatment. The inclusion of macroalgae in the synbiotic led to a lower nitrate concentration at the end of the trial. However, the suspended solids negatively affected the growth of the macroalgae, and caused oyster mortality. The SOMsy promoted a higher final biomass and a lower feed conversion ratio in the shrimp compared to the monoculture (S). Therefore, the use of the integrated system with shrimp, oyster, and macroalgae in a synbiotic system provided more sustainability, as well as higher shrimp productivity, and was more economically advantageous compared to the other treatments.
