In the present investigation, we evaluated if the presence of tilapia affects growth and survival of shrimp during pre-growth and grow-out phases. In both experiments, we used a random-blocks design in a single earth pond (0.75 ha) that was prepared and divided into nine (7 x 30 m) enclosures that were considered to be three blocks of three enclosures each. Each randomly stocked block consisted on Pacific white shrimp Litopenaeus vannamei (30 shrimp/m2) and three different densities (0.0, 0.25 and 0.50 fish/m2) of red tilapia hybrids (Oreochromis mossambicus x Oreochromis niloticus) to give three different treatments with three replicates. The results from the pre-growth and grow-out experiments followed the same trend. In both cases, we found no significant statistical differences (P>0.05) in the final average weight of the shrimp. However, the experimental blocks had a significant (P<0.05) effect on the mean sample weight of shrimp. Shrimp in blocks B and C were significantly bigger than shrimp from block A (P<0.05). For both experiments, we found no effect of the presence of tilapias on survival or growth of shrimp.RESUMENEvaluamos si la presencia de tilapias libres afecta el crecimiento y la supervivencia de camarones en fase de preengorda y engorda. Para ambos experimentos, utilizamos un diseño de bloques al azar en un estanque rústico (0.75 ha) que fue preparado y dividido en nueve encierros (7 x 30 m), se formaron tres bloques con tres encierros cada uno. Cada encierro dentro de cada bloque fue aleatoriamente seleccionado para sembrar camarón blanco del Pacífico, Litopenaeus vannamei (30 camarones/m2) y tres diferentes densidades (0.0, 0.25 y 0.50 peces/m2) de híbrido de tilapia roja (Oreochromis mossambicus x Oreochromis niloticus) para formar tres tratamientos con tres réplicas. Los resultados del experimento de pre-engorda y engorda siguieron la misma tendencia. En ambos experimentos no encontramos diferencias estadísticamente en el crecimiento de los camarones ni en las tilapias. Sin embargo, los bloques experimentales presentaron diferencias significativas (P<0.05) en el peso promedio final. Los camarones de los bloques B y C fueron estadísticamente más grandes (P<0.05) que los del bloque A. Para las dos etapas de crecimiento de los camarones, no se observó un efecto de la presencia de tilapias sobre la sobrevivencia o crecimiento de los camarones.

Aim of study: To determine the effects of white shrimp (Litopenaeus vannamei) and tilapia nilotica (Oreochromis niloticus var. Spring) in monoculture and co-culture on water quality variables and production in earthen ponds during dry and rainy seasons.Area of study: A shrimp farm (total area 20 ha) at Chiripa, San Blas Nayarit, Northwest coast of Mexico (21° 37' 34.53 " N; 105° 18' 16.31" W).Material and methods: Two production cycles were performed in a completely randomized design consisting of two treatments and three replications each during rainy season (September-December) and dry season (February-May). Shrimp was the main crop and tilapia the secondary species.Main results: White shrimp (10 org/m2) can be co-cultured with Nile tilapia at a stocking high density (4 org/m2), leading to improved water quality and better utilization of nutrients in dry season than in rainy season. However, the shrimp’ highest weight was recorded in the tilapia-shrimp co-culture ponds during rainy season due to higher water temperature and better quality of live food. The mean individual weight, biomass and survival of the shrimp, in co-culture ponds were greater than those of the shrimp monoculture, in the two seasons studied.Research highlights: There was a trend towards greater concentration of nutrients in the water of the monoculture ponds and, lower dissolved oxygen and higher BOD5 in co-culture ponds in the dry season than in the rainy season.

The study explored the possibility of integrating the grey mullet Mugil cephalus (Linnaeus, 1758) along with Pacific white shrimp  Litopenaeus vannamei (Boone, 1931) in floating cage culture in Godavary Estuary, India. Post-larvae (PL 12) of L. vannamei (3 lakhs nos.), were acclimatised and nursed in five hapas for 28 days at a density of 3333 nos. m-2, with survival of 60%. L. vannamei juveniles having mean weight of 0.86 g, stocked at a density of 1060 nos. m-2, were cultured along with and without pre-stocked M. cephalus, in three floating cages each. Six thousand fry of M. cephalus (mean length 4.17 cm; mean weight 1.22 g) were stocked in three cages at uniform density of 23.5 nos. m-3, three months prior to stocking of L. vannamei. Shrimps were fed commercial pellets @ 3-8% of body weight, four times daily and harvested after 68 days. Fishes were fed with pelleted feed and after five months attained mean length of 23.7 cm and mean weight of 274.1 g. Survival was 46.4% and the average production obtained was 250.2 kg. At harvest, L. vannamei in monoculture system attained mean weight of 13.3 g and in the mixed culture system, average weight obtained for the shrimps was 13.5 g. Survival, feed conversion ratio (FCR) and production of L. vannamei from monoculture were 64.7%, 2.0 and 258.9 kg and from mixed culture 76.8%, 1.6 and 311.5 kg respectively. Daily weight increment and specific growth rate (SGR) of L. vannamei was 0.18 g and 4.06 for monoculture and 0.19 g and 4.01 for mixed culture, resepectively. Feed conversion, survival and production of L. vannamei were significantly (p<0.05) better in mixed culture, confirming technical superiority of mixed culture over monoculture.
