Mónica Hernández Rodríguez Ciencias de la Tierra production intensive culture Litopenaeus vannamei recirculating seawater system The intensive culture of Litopenaeus vannamei continues to expand and their study in recirculating rearing tanks with limitedwater volume is scarce. The aim of this research was to cultivate white shrimp postlarvae (PL 13) for five months in a 5.85-m3rearing unit. Vertical mosquito screen curtains augmented the tank area of the rearing unit from 13.9 (wall surface) to 84.6 m2.The total water volume (11 m3) was recirculated at a rate of 7.2 m3 h1. Shrimp postlarvae were fed with fine-graded Camaroninamixed with water for one month and then replaced with Camaronina pellets distributed automatically twice a day. During thetrial, water temperature ranged from 23.0ºC to 25.8ºC, oxygen from 5.3 to 7.5 mg L1, and salinity from 27.5 to 28.4. At theend of the experiment, water quality was pH 7.4, NH3-N = 0.8 mg L1, NO2-N = 0.287 mg L1, PO4 = 7.9 mg L1, and total PO4 =1.71 mg L1. The final crop for the unit was 56.7 kg, with a shrimp mean mass of 4.001 g, and a maximum and minimum of 8.484and 0.384 g, respectively. In terms of the total recirculated seawater volume (11 m3), the production was 5.15 kg m3, and inrelation to the tank volume, 9.7 kg m3; considering the tank surface without curtains, production was 4.1 kg m2, and withcurtains, 0.67 kg m2. The design and installation of the curtains is a viable tank modification to increase the available space in areduced water volume. Our results indicate that the mean residence time (1.23 h) of the water recirculation in the rearing unit cansustain high water quality. Another extension of our results is to make use of the design to culture postlarvae as a nursery unit toraise juveniles less than 4 g for subsequent transfer to culture facilities. However, it is much more important to implicate in theanalysis the use of land that in some countries, such as Mexico, constitutes vast regions of useful agricultural land, transformedinto culture ponds to increase the national shrimp production. In this sense, shrimp production of the experiment in terms of thebase area (7 m2) of the culture tank was 8.1 kg m2. 2004 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48003003 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1B Vol.30 |
