Marine and Freshwater Behaviour and Physiology, 46 (6), pp. 399-417. http://www.scopus.com/inward/record.url?eid=2-s2.0-84887984026&partnerID=40&md5=51704b7b1289ec5649fa304b92e76163; https://doi.org/10.1080/10236244.2013.849058
We used a response-surface analysis to determine the importance of different factors affecting the resting routine metabolic rate (QO2) of the white shrimp Litopenaeus vannamei. The oxygen consumption rates were estimated using a multi-factorial design with 28 combinations of different salinities (15, 20, 25, 30, 35, 40 and 45 psu) and temperature (20, 25, 30 and 35 °C) values. The response-surface analysis produced a quadratic function showing that temperature more profoundly affects the oxygen consumption rate. Response-surface curves were generated to predict the optimal conditions resulting in oxygen consumption to better understand the successful growth of this species.
