“…The effects of filtering shellfish on suspended solids and turbidity have been observed in laboratory-scale studies [49,50] and in a larger tank study [51]. Reduced turbidity was probably caused by feeding on organic particles.…”

Wastewater effluent from aquaculture ponds can affect aquatic ecosystems. To mitigate this problem, we designed 2 sets (southern and northern) of land-based and farm-scale sequential integrated multi-trophic aquaculture (IMTA) systems in order to reduce water pollution and to diversify and optimize aquaculture products in coastal southern Taiwan. In each system, the 1st pond cultivated milkfish as the main aquaculture product, the 2nd pond cultivated Portuguese oysters as the product to reduce suspended particles, and the 3rd pond cultivated the seaweed Gracilaria sp. as feed and to absorb nutrients. Photosynthetic bacteria (PSB) were added to the southern system in order to reduce nutrients. The objective of this study was to evaluate and compare performance parameters of the compartments and the overall IMTA systems preliminarily. Our results showed that the southern system with the addition of PSB had lower PO 4 −3 -P, slightly higher turbidity, and higher brown algal biomass than the northern system. In the southern system, PO 4 −3 -P and cyanobacteria levels were lowest at the end of the seaweed pond. In the northern system, NO 2 − -N and phytoplankton levels were lowest at the end of the seaweed pond. Turbidity was reduced in the oyster pond and further reduced in the Gracilaria pond in both systems. The high seaweed yield in the northern system indicated substantial nutrient absorption. Advantages and limitations in terms of water purification and aquaculture production of these IMTA systems are evaluated in the present paper.

“…Ramos et al (2009) observaram redução de 70,6% de sólidos suspensos de efluente da carcinicultura utilizando a ostra C. rhizophorae em condições laboratoriais com animais entre 76 e 80 g, sendo superiores aos observados nesse experimento. Estas diferenças observadas podem estar relacionadas ao tamanho dos animais, tempo de residência e salinidade da água.…”

ResumoEste estudo teve como objetivo avaliar a capacidade da ostra Crassostrea rhizophorae como filtro biológico para o tratamento de efluentes da carcinicultura e verificar a sua condição microbiológica após processo de filtração. Um total de 1080 ostras foram distribuídas em lanternas de engorda, mantidas em 12 tanques de fibra de vidro (170 L), em um delineamento inteiramente casualizado, com quatro tratamentos (sem ostras, 60, 120 e 180 ostras) e três repetições. O efluente utilizado foi proveniente do tanque de sedimentação de uma fazenda de produção de camarão. Semanalmente foram analisados: amônio (N-NH 4 + ), ortofosfato (P-PO 4 3-), total de sólidos suspensos (TSS) e clorofila-a (Cl-a) do efluente de entrada e saída. Os tratamentos com ostras apresentaram remoção semelhante (P>0,05) nos teores de Cl-a e TSS do efluente, sendo superiores (P<0,05) ao tratamento sem ostras. Não foi observada melhoria na qualidade do efluente após a passagem pelos tanques experimentais em relação ao N-NH 4 + . Em relação ao P-PO 4 3-, todos os tratamentos reduziram as concentrações desse nutriente de forma semelhante (P>0,05). Não foram observadas diferenças (P>0,05) para os valores de coliformes totais e de cobre, independentemente da densidade de estocagem. Nas amostras analisadas não foram encontrados coliformes fecais e Salmonella spp. As ostras melhoram a qualidade da água, exceto N-NH 4 + , e não apresentam contaminantes que inviabilizem seu consumo.

It was used the effluent from the sedimentation tank. Weekly were analyzed: ammonia nitrogen (N-NH 4 + ), orthophosphate (P-PO 4 3-), total suspended solids (TSS) and chlorophyll-a (Cl-a) of the input and output effluent. The treatments

“…It is well known that bivalves consume suspended particles (organic and inorganic) from the water column, retaining the organic fraction and discarding the inorganic (Troell & Norberg 1998, Pfeiffer et al 1999, Kasai & Nakata 2005. However, the inorganic fraction may also be decanted from seston by the filtration and discarding of bivalves (Ramos et al 2009). …”

Resumen.-La almeja negra, Chione fluctifraga, puede ser utilizada para biorremediar efluentes de descarga en cultivos de camarón. Con este propósito se evaluó durante 77 días, el efecto de dos densidades de almeja (12,5 y 25 especímenes m -2 ) y un control (0 m -2 ) sobre la calidad de agua de efluentes crudos de un cultivo semi-intensivo de camarón (Litopenaeus vannamei; 25 m -2 ). Parámetros tales como, sólidos suspendidos totales (TSS), sólidos orgánicos suspendidos (OSS), nitrógeno amoniacal total (TAN) y nitrógeno total (TN) fueron medidos en los efluentes crudos, control, tratamientos y agua del estuario (fuente de agua para el cultivo de camarón). Los TSS y OSS disminuyeron en el control y los tratamientos en comparación con los efluentes sin tratar. Los TSS y OSS disminuyeron durante los primeros 22 días, sin registrar diferencias entre control y tratamientos. Sin embargo, los tratamientos tuvieron una mayor disminución en los niveles de TSS y OSS a los 48 y 77 días de cultivo, en comparación con el control. Los niveles de TAN registraron los valores más bajos en ambos tratamientos, seguidos por el control y los efluentes de camarón; no se observaron diferencias significativas para el TN. Los resultados indican que Chione fluctifraga tiene capacidad como biorremediador y puede sobrevivir en efluentes de estanques de camarón.Palabras clave: Biofiltración, agua de descarga, contaminación ambiental, cultivo de camarón, calidad de agua Abstract.-The black clam, Chione fluctifraga, can be used to bioremediate discharge effluents produced by shrimp aquaculture. With such purpose we evaluated during 77 days, the effect of two densities of clams (12.5 and 25·specimens m -2 ) and a control (0·m -2 ) on the water quality of raw effluents from a semi-intensive culture of shrimp (Litopenaeus vannamei; 25 m -2 ). Parameters such as total suspended solids (TSS), organic suspended solids (OSS), total ammonium nitrogen (TAN) and total nitrogen (TN) were measured in raw effluents, control, treatments and estuary (water source for shrimp culture). The TSS and OSS diminished in control and treatments, compared with untreated effluents. The TSS and OSS decreased over time with no significant difference observed among the treatments during the first 22 days of trial. However, treatments had a greater decrease of TSS and OSS levels at days 48 and 77 compared with the control. TAN recorded the lowest levels in both treatments, followed by control and effluents respectively; no significant differences were observed for TN. The results indicate that Chione fluctifraga has ability as biorremediator and it does survive well in shrimp pond effluents.
