“…No presente trabalho, mesmo com as trocas de água no tratamento controle, a concentração de nitrito atingiu valores significativamente maiores em comparação ao tratamento com probióticos, o que indica maior eficiência do probiótico para manutenção da qualidade da água, sem a necessidade de renovações. Portanto, a utilização de probióticos na aquicultura permite melhoria nos parâmetros de qualidade de água, além de diminuir impactos econômicos e ambientais por meio da redução na quantidade de água utilizada e na geração de efluentes dos sistemas de produção (Ziemann et al, 1992;Wang et al, 2005).…”

“…O acúmulo desses compostos é um fator limitante nos sistemas de produção (Banerjee et al, 2010). Para solucionar esses problemas, é necessário realizar frequentes trocas de água dos tanques de cultivo, que resultam em descarga de resíduos que podem causar eutrofização do ambiente natural (Ziemann et al, 1992). Nos sistemas de cultivo com adição de probióticos, as trocas de água podem ser diminuídas ou até mesmo eliminadas, uma vez que os probióticos atuam na absorção e na decomposição da matéria orgânica na água e nos sedimentos, o que melhora a qualidade de água (Wang et al, 2005).…”

Resumo -O objetivo deste trabalho foi avaliar o uso de probióticos na produção de pós-larvas do camarão-rosa (Farfantepenaeus brasiliensis). Utilizou-se o delineamento experimental inteiramente casualizado, com dois tratamentos -uso de probióticos (Bacillus spp.) e controle com uso de antibiótico (eritromicina) -e quatro repetições. Pós-larvas no estágio PL 1 foram estocadas em cada parcela experimental (3,0 L) e cultivadas até o estágio PL 10 . As variáveis de qualidade de água e o desenvolvimento de bactérias do gênero Vibrio, na água de cultivo, foram monitorados ao longo do experimento. Ao final do período experimental, as pós-larvas foram avaliadas qualitativamente e quanto à sobrevivência, ao peso e ao comprimento. Nas variáveis de qualidade de água, apenas o nitrito apresentou valor significativamente maior no tratamento com antibiótico. Para as variáveis peso e comprimento final, não houve diferenças significativas entre os tratamentos. Não foram observadas diferenças significativas entre os tratamentos quanto à qualidade das pós-larvas e à concentração de Vibrio spp. na água. A utilização de antibiótico pode ser substituída pelo emprego de probióticos durante a produção de pós-larvas de F. brasiliensis.Termos para indexação: Bacillus, Farfantepenaeus brasiliensis, Vibrio, antibiótico, crescimento, sobrevivência. Use of probiotics in the production of pink shrimp postlarvaeAbstract -The objective of this work was to evaluate the use of probiotics in the production of postlarvae of pink shrimp (Farfantepenaeus brasiliensis). A completely randomized experimental design was used, with two treatments -use of probiotics (Bacillus spp.), and a control using antibiotic (erythromycin) -, and four replicates. Postlarvae in the PL 1 stage were stocked in each experimental unit (3.0 L) and cultured until stage PL 10 . Water quality variables and the development of the bacteria of the genus Vibrio, in the culture water, were monitored throughout the experiment. At the end of the experimental period, postlarvae were evaluated qualitatively and for survival, weight, and length. Regarding water quality variables, only nitrite was significantly higher in the antibiotic treatment. For the variables weight and length, there were no significant differences between treatments. No significant differences between treatments were observed in postlarvae quality and in the concentration of Vibrio spp. in the water. The use of antibiotics may be replaced by probiotics during production of F. brasiliensis postlarvae.

“…Similar results were obtained by Kimpara 26 , who found that there was no significant difference among the concentrations of total nitrogen, ammonia, nitrite and nitrate among treatments and among treatments themselves and the water supply. However, when Ziemann et al 33 analyzed the affluent water quality and the water effluent of fresh-water fish and shrimp ponds and that of seawater fish and shrimp, they discovered that effluent had a lower quality than that of the affluent in most parameters analyzed. In fact, concentrations of suspended material and pigments in the effluents of freshwater fish and shrimps were higher.…”

Effluents quality during the grow-out phase of the amazon shrimp macrobrachium amazonicum

In recent years shrimp culture farms have been one of the most growing sectors in aquaculture. Research has been carried out in order to establish a sustainable production maintaining profit and low environmental impact. Current investigation analyzed source and effluent water produced during the final grow-out phase of the Amazon shrimp (Macrobrachium amazonicum). Twelve natural-bottom ponds, with continuous water flow and stock density comprising 40, 60, 80 and 100 young shrimps/m² were analyzed. The experiment design comprised totally randomized blocks with four treatments and three replications. Microbiological analyses for Escherichia coli was attempted, coupled to physical and chemical analyses for pH, temperature, total suspended solids, total nitrogen, nitrite, nitrate, biochemical oxygen demand and chemical oxygen demand of water supply and pond effluents. Results show that whereas effluent quality complied with current legal rules, there was no significant difference between supply and effluent water for the analyzed variables and between stock densities. Under the conditions investigated and the intensification of culture in the final grow-out phase up to a density of 100 young shrimps/m², the production of M. amazonicum reveals low potential for environmental impact for the variables analyzed.

“…The water quality of shrimp farm effluent depends on a number of factors, including pond soil type, quality of influent water, stage of grow out season and management practices employed [58]. Water pollution is largely associated with the use and discharge of water in shrimp ponds [29].…”

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.
