“…It is therefore understandable that, in our study, with a low shrimp:tilapia ratio and tilapias kept free in the water column, competition for pellet feed was very intense, reducing shrimp and tilapia performance. Muangkeow et al (2007), in an experiment with a mixed shrimp-tilapia polyculture system, also observed that when the shrimp:tilapia ratio was low (13:1 and 20:1), the presence of tilapia affects shrimp weight because fish and shrimp compete for natural food. In this same study, they observed that shrimp grew, when the shrimp:tilapia ratio was higher (40:1 and 100:1) in monoculture.…”

“…Tilapia-shrimp or tilapia-prawn polyculture adoption has been expanded among producers in many countries, and some studies have been conducted to test the efficiency of these systems (Candido et al, 2005;Tendencia et al, 2006Tendencia et al, , 2011Muangkeow et al, 2007;Uddin et al, 2007Uddin et al, , 2009El-Sherif & Ali Mervat, 2009;Souza et al, 2009;Martínez-Porchas et al, 2010;Yuan et al, 2010;Shahin et al, 2011;Bessa Junior et al, 2012).…”

-The objective of this work was to evaluate the performance of Pacific marine shrimp (Litopenaeus vannamei) and tilapia (Oreochromis niloticus), in a polyculture in tanks subjected to different stocking densities and feeding strategies, in comparison with monoculture. Two experiments were performed, at the same time, in a completely randomized design with three treatments and four replicates each. Treatments for experiment I were: monoculture with 10 shrimp per m² (10S:0T); polyculture with 10 shrimp and 0.5 tilapia per m² (10S:0.5T); and polyculture with 10 shrimp and 1 tilapia per m² (10S:1T). Shrimp was the main crop, and feed was provided based on shrimp biomass. Treatments for experiment II were: monoculture with 2 tilapia per m² (2T:0S); polyculture with 2 tilapia and 2.5 shrimp per m² (2T:2.5S); and polyculture with 2 tilapia and 5 shrimp per m² (2T:5S). Tilapia was the main crop, and feed was provided based on fish requirements. In the experiment I, tilapia introduction to shrimp culture resulted in lower shrimp growth and poor feed conversion rate. In experiment II, shrimp introduction to tilapia culture did not interfere with fish performance. Polyculture is more efficient with the combination of 2 tilapia and 2.5 or 5 shrimp per m² and feed based on fish requirements.

“…Several factors affect the economic return of aquaculture systems such as yield, sale prices, feed costs, fingerlings or juveniles costs, system investments and operating costs (Muangkeow et al 2007, de Oliveira et al 2012. In the present study, total revenues and total costs were highest in the IAC treatment, as was the net income.…”

The Chinese soft-shelled turtle Pelodiscus sinensis is a highly valued freshwater species cultured in China. A 122 d experiment was conducted to assess the effects of water spinach Ipomoea aquatica cultivation in floating beds on water quality, and growth performance and economic return of P. sinensis cultured in ponds. Two treatments, each in triplicate, with and without I. aquatica cultivation were designed. Results showed that the levels of total ammonia nitrogen (TAN), total nitrogen (TN), total phosphorus (TP), chlorophyll a (chl a) and turbidity in treatments with I. aquatica cultivation (IAC) were significantly (p < 0.05) lower than those in treatments without I. aquatica (control). Mean TN and TP concentrations in the IAC treatment were 27.9 and 42.5%, respectively, lower than in the control treatment at the end of the experiment. The presence of I. aquatica also has a positive effect on the performance of P. sinensis. Although no significant difference was found in specific growth rate (SGR) between the 2 treatments, mean survival rates, production and net income were significantly higher in the IAC treatment compared to the control (p < 0.05). These results suggest that I. aquatica cultivation in the pond system of turtles has a synergistic effect on overall economic return and is effective at improving turtle growth performance and water quality.

Brackish Shrimp Farming in Northeastern Brazil: The Environmental and Socio-Economic Impacts and Sustainability

Despite the economic importance of farmed shrimp, a number of technical, environmental, economic and social problems have been widely reported in the international literature. This paper focuses on the environmental and socio-economic impacts of semi-intensive and intensive shrimp farming in the coastal region of Northeastern Brazil and the identification of options for sustainable production. In this Region, the total area dedicated to shrimp farming is approximately 18,500 ha, of which 5750 ha are located in Ceará State. The estuary of Jaguaribe river has the largest number of shrimp farms in the state of Ceará. Currently, the industry has 64 participating farms with a total area dedicated to shrimp farming of 2411.3 ha. In 2011, the total production was 13,110 tons of shrimp with an average yield of 6.3 ton ha −1 ·year −1 in a pond area of 2071.2 ha. This industry employs 2350 people that represent 23.2% of jobs generated in the two municipalities where the Jaguaribe river estuary is inserted. Compared with other countries, Brazil has reduced its exports due to high cost inputs for shrimp farming. However, the Brazilian shrimp industry has benefited from high domestic prices, despite the decreases in international price of shrimp. In 2011, the prices for size category ranged between U$ 4.67 -6.04 for 80/100 (count of head-on shrimp), U$ 4.95 -6.60 for 70/80 and U$ 5.85 -8.10 for 50/60. The major environmental impacts in this industry have focused on the water pollution and loss of mangroves. However, no change in parameters of water quality was observed during the period 2010-2012, indicating that this estuary has some capacity to process pond-derived nutrients while only 3.7 ha of mangrove forests were used to shrimp pond. The results of this investigation demonstrate that Brazilian shrimp industry requires improved management and development policy for a sustainable growth.
