Effect of temperature on nursery and compensatory growth of pink shrimp Farfantepenaeus brasiliensis reared in a super-intensive biofloc system

Abstract This study aimed to evaluate the effect of different temperatures on the nursery phase and compensatory growth of pink shrimp, Farfantepenaeus brasiliensis , reared in a biofloc technology (BFT) system. The 30-day nursery phase trial was conducted at 21 °C, 24 °C, 27 °C, 30 °C and 33 °C. At the end of the nursery phase, the shrimp were acclimated at 30 °C (±1 °C) and restocked at 100 juveniles/m 2 to check the compensatory growth during 15 days, with the following treatments: 21 °C (30 °C), 24 °C (30 °C), 27 °C (30 °C), 30 °C (30 °C) and 33 °C (30 °C), in which the first numbers correspond to temperature used in the nursery study and the 30 °C is the temperature used in the compensatory growth study. The mean final weight significantly increased with temperature at the end of the nursery phase ( p F. brasiliensis at high stocking density in BFT systems should be conducted at approximately 27 °C. However, this phase can also be carried out at lower temperatures, which can ensure high survival and compensatory growth when the temperature is increased.
