| contents | Hyper-intensive farming white shrimp Litopenaeus vannamei (Decapoda: Penaeidae) in a seawater tank under semi-controlled conditions A.A. Ortega-Salas L.A. Rendón M. Multidisciplinaria (Ciencias Naturales y Exactas) semi Growth biomass survival high density Shrimp development to a commercial size in high density culture saves food and avoids predators and disease. Our study was conducted to calculate the growth of white shrimp Litopenaeus vannamei by hyper- intensive cultivation under semi-controlled conditions. We seeded at a density of 550 shrimp per m 3 during the first cycle and 400 shrimp per m 3 in the second cycle in an outdoor tank of 6m 3 or 6m 2 covered with mesh, constant aeration. The shrimp were fed Artemia franciscana during the first two weeks and camaronina pellets (35% protein) as required, in food baskets, aftterwards. The temperature ranged from 22,3 to 31,3°C, pH 7,5-8,7, oxygen 4,26±1,43. The tanks are siphoned of debris every other day, and water was replaced according to a program. The food conversion ratio (FCR) was 1:1,3. The shrimp were measured weekly to calculate growth with the Bertalanffy model. Survival in the first cycle was 95,8 ( 97,9% for the second cycle). Population parameters (maximum likelihood method) for the first cycle were k=0,0301, L∞ =322,16 and t 0 =-0,8852; second cycle: k=0,0203, L∞ =294,42 and t 0 =-5,3771. There was rapid growth during the first 10 weeks. Biomass was 27kg for the first cycle (second: 16kg). 2013 artículo científico 1659-4266 https://www.redalyc.org/articulo.oa?id=515651979010 en http://www.redalyc.org/revista.oa?id=5156 UNED Research Journal / Cuadernos de Investigación UNED application/pdf Universidad Estatal a Distancia UNED Research Journal / Cuadernos de Investigación UNED (Costa Rica) Num.1 Vol.5 |
