“…In this study, the survival, harvesting weight and specific growth rate were significantly higher with the larger size ditch is due to lower competition for space and food, and the result is very similar to Hossain and Joadder () with a stocking density of 4940 ha −1 for O. niloticus and 1% ditch in rice–fish culture system. Rice fields show high rates of natural production (Tuyen ) providing large choices of food sources and thus benefiting the fish integrated into the paddy (Zimmermann, Nair & New ). Therefore, high growth rates in integrated cultures can be attributed to the effective utilization of ecological niches and the rich detrital food web especially for bottom dwellers (Mohanty, Verma & Brahman ), fish grazing on macrophytes and algae, plankton‐feeder and scavenger like tilapia.…”

Performance of mono-sex tilapia (Oreochromis niloticus) in rice field with different ditch size

et al. 2013

The effects of ditch size on growth and production of mono-sex tilapia, Oreochromis niloticus in rain fed concurrent rice-fish system were technically and economically evaluated for a period of 4 months. Three different ditch sizes were tried: 5%, 10% and 15% of the total cultivable rice field. The fish fingerlings stocking density (5000 ha À1 ) and management practices were similar in all plots. The water temperature, dissolve oxygen, pH, Secchi disc visibility, ortho-phosphate, ammonia nitrogen and alkalinity were found to be in the range of 31.5-31.9°C, 5.10-5.27 mg L À1 , 7.56-7.62, 34.81-35.41 cm, 0.88-0.96 mg L À1 , 0.014-0.021 mg L À1 and 66.23-69.76 mg L À1 , respectively, and all the values were found suitable for tilapia fish farming. Sediment organic matter, available nitrogen and phosphorous were increased significantly (P < 0.05) in all plots after cultivating the fish. Larger ditch size (15% of the total land area) resulted in significantly (P < 0.05) higher specific growth rate, survival and fish production compared with the smaller (5%) and medium (10%) ditch sizes. However, significantly (P < 0.05) higher net income and benefit-cost ratio were obtained in medium ditch size with the values of 2.6% and 3.6% higher than the smaller and larger ditch sizes respectively. It is concluded that rice-fish farming in a rain fed ecosystem of Bangladesh with medium ditch size and stocking density of 5000 ha À1 mono-sex tilapia can achieve better economic return.

“…Only a few farms produces prawns in polyculture with tilapia, but there is potential for expansion as the introduction of freshwater prawns in tilapia ponds can increase profits (Zimmermann, Nair & New ). In fact, the low profitability of fish culture in ponds in Brazil causes hundreds of hectares of ponds to be unused or under‐utilized all over the country, and these could be used for polyculture.…”

This article describes some aspects of the current status of Macrobrachium rosenbergii (De Man 1879) and Macrobrachium amazonicum (Heller 1862) farming in Brazil, including a brief description of the technologies used. A history of the farming of M. amazonicum is provided, together with the marketing strategies currently employed for freshwater prawns in Brazil and future trends. It was concluded that freshwater prawn farming in Brazil currently has a favourable scenario for expansion due to increasing demand and to prospects of an improved organization of the productive chain.

“…Several studies have addressed polyculture techniques to increase productivity in aquaculture systems. Polyculture systems, also called multi-trophic systems, relies on the cultivation of two or more species that differ in feeding behavior, habits and ecological requirements, to increase production in the same production unit (Zimmermann and New, 2000). Some authors suggest that tilapia is one of the most promising species in polyculture either in combination with other species of fish, or crustaceans (Wang and Lu, 2016).…”

Effect of Red tilapia (Oreochromis mossambicus × Oreochromis niloticus) on growth and survival of the pacific shrimp (Litopenaeus vannamei) in simultaneous polyculture under marine conditions//Efecto de la tilapia roja (Oreochromis mossambicus × Oreochromis niloticus) en el crecimiento y supervivencia del camarón (Litopenaeus vannamei) en policultivo simultáneo bajo condiciones marinas

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.
