Abstract
Shrimp can adapt to various types of farming systems, especially in ample salinity fluctuations and different temperatures, which means their growth is rapid even outside their natural habitat. The objective of this study is to verify the growth of Pacific white shrimp (Penaeus vannamei) in a water recirculation aquaculture system (RAS) and demonstrate that the shrimp industry can be practiced sustainably. A total of 60 animals were distributed in a completely randomized design, with six replications at a stocking density of one animal per 15 L, resulting in 10 animals per experimental unit. The Pacific white shrimp used in the study were from the Speed Line Aqua lineage (Aquatec) with an initial weight of 9.93 ± 1.16 g, grown in saltwater with a salinity of 20. Feeding occurred three times a day with balanced commercial food; daily water quality monitoring was conducted. The shrimp were weighed at the beginning of the experimental period, as well as every 15 days for 60 days, to obtain performance parameters (weight gain, feed consumption, apparent feed conversion, specific growth rate, and protein efficiency rate). With the performance data, the Gompertz model was applied to describe shrimp growth. Based on the general results, RAS can be used for shrimp in a super-intensive system. The values estimated by the Gompertz model accurately described the growth of Pacific white shrimp in RAS systems within a weight range of 10.84 g (minimum) to 69.25 g (maximum). The optimal weight for maximum growth performance was identified as 40.05 g live weight for this farming system. The daily maturity rate (b) was estimated to be 0.0196 g d-1, representing the average daily mass gain an organism accumulates as it progresses toward full maturity.
