“…In the amphipod Gammarus wilkitzkii, the pooled O:N ratio for 24-h osmotic stress varied from 21 under hypo-osmotic stress to 37 under hyperosmotic stress (Aarset and Aunas, 1990). Stern et al (1984) reported that the energy substrate utilization in M. rosenbergii changed as a function of osmotic stress. In fresh water and slightly brackish water, the O:N ratio for this prawn reflected lipid-and or carbohydrate-dominated metabolism, and in more saline water (15‰ and 24‰), there was a marked decrease in O:N ratio indicating that prawns grown in these media increased protein catabolism relative to lipid catabolism.…”

however, few studies deal with the energy requirement under different salinity regimes (Cheng and Fang, 1986;Guerin and Stickle, 1992). Similarly, the effect of salinity on the rate of crustacean ammonia excretion has extensively been studied (Regnault, 1984;Taylor et al., 1987;Diwan and Baskaran, 1992;Chen and Chia, 1996). Further, researchers are also looking into the influence of environmental factors, including salinity, on the relationship between oxygen consumed and excreted nitrogen (atomic O:N ratio), as it can provide information on the changes in energy substrate utilization under various environmental regimes (Mayzaud and Conover, 1988).The present study was carried out with the objective of understanding the metabolic responses of M. monoceros, a candidate species for aquaculture, in response to abrupt salinity changes in the medium. Variations in metabolic response (measured as oxygen conMetapenaeus monoceros, a tropical penaeid with wide distribution in the Indo-Pacific region is considered a candidate species for aquaculture. Although it is a smaller species when compared to tiger shrimp Penaeus monodon (Fabricius), it nevertheless has several good attributes for aquaculture such as tolerance to a wide range of salinities, resistance to handling and transportation stress, and good market acceptability. These shrimps, like other penaeids, have an estuarine phase in their life cycle and thus get exposed to wide fluctuations in salinity. Because salinity is an important environmental variable that has significant influence on the energy budget of estuarine and marine animals, knowledge of the energy requirement of the animal under different salinity regimes will be useful to aquaculturists in formulating improved culture practices for maximizing growth and returns.A great deal of research has been carried out to study the effect of salinity on the metabolic rate of crustaceans (Rao, 1958 in) A B S T R A C TThe present investigation was undertaken to study the effect of an abrupt change in the salinity of the medium on the oxygen consumption and ammonia-N excretion of the marine penaeid shrimp Metapenaeus monoceros (Fabricius). Results showed that in both low-saline (5‰) as well as highsaline (35‰) acclimated shrimps the respiratory rates were significantly lower in midrange salinities (20‰ and 25‰) and significantly higher in both low (5‰, 10‰, and 15‰) and high (30‰ and 35‰) salinities. A significant increase in ammonia-N excretion was observed when high-saline acclimated shrimps were abruptly exposed to different grades of low-saline media. Exposure to different grades of high-saline media on the other hand induced a significant decrease in ammonia excretion rate of low-saline acclimated shrimps. The O:N ratio (ratio of oxygen consumed to nitrogen excreted in atomic equivalents) showed a decreasing trend when the high-saline acclimated shrimps were abruptly exposed to low-saline media, indicating a shift towards protein dominated metabolism. A reverse trend could be observed in the O:N ratio when ...

Abstract. Changes in salinity affect the metabolic rate of the sympagic amphipod Onisimus glacialis collected from the Barents Sea in 1986 and 1988. When transferred from 35 to 5 ppt S, oxygen consumption and ammonia excretion both increase three-fold during the first 5 h of exposure, and they remain high throughout the rest of the experimental period (26 h). During 24-h acclimation to various salinities (5 to 45 ppt), the amphipods exhibit a respiratory and excretory response to hyper-and hypoosmotic stress; however, a rather constant O:N atomic ratio (around 15) was obtained at the experimental salinities, indicating protein/lipids as metabolic substrate. Both rates of oxygen consumption and ammonia excretion increased with an increasing osmotic difference (0 to 650 mOsm) between the haemolymph and the environmental medium, indicating higher energy requirements for osmotic and ionic regulation at low salinities. In amphipods abruptly transferred from 35 to 5 ppt, a minor decrease of the haemolymph sodium concentrations together with an increased ammonia excretion output indicate a counter-ion regulation of NH~ and Na + during hyposmotic stress.

“…Con relación al oxígeno disuelto en el agua (OD), la concentración en los tratamientos con TaM fue superior que en los controles (Tabla 1), y no se determinaron niveles críticos de OD (Stern, 1984;Whetstone et al, 2002). Los valores obtenidos en presencia de TaM durante el día comprueban la producción de oxígeno atribuida a la comunidad fotosintética en los consorcios (Bender et al, 2004), a diferencia de los sistemas control (sin TaM).…”

Biorremediación de los efluentes de cultivo del camaróndemostraron que los TaM redujeron los niveles de nitrógeno amoniacal por encima del 71% diariamente; la demanda bioquímica de oxígeno (DBO 5 ) se redujo más de 68% y los sólidos suspendidos (SST) hasta en 62% al compararse con los sistemas control (p < 0,05). Los TaM secuestran la materia orgánica y mineral y ejercen un efecto clarificador en la columna de agua. La descomposición de la materia orgánica se debe al acoplamiento estrecho entre fotoautótrofos y nitrificantes contenidos en los TaM. Esta condición aumenta los niveles de nitrógeno inorgánico en la columna de agua y acelera la nitrificación por arriba de 10 mg N-NO 3 -L -1 (120 ind m -2 ), con lo cual se produce un aumento de hasta 750% más nitratos que los sistemas control. La remoción del fósforo no fue significativa (p > 0,05). El agua bio-remediada tiene un efecto positivo en el cultivo de Litopenaeus vannamei, y promueve el crecimiento y sobrevivencia en presencia de TaM en el SR.

Bioremediation of effluents of the culture of Litopenaeus vannamei (Boone, 1931) using microbial mats in a recirculating systemABSTRACT. We developed a recirculating system integrating shrimp culture with microbial mats aiming to mitigate the environmental impacts of by-products from shrimp culture and to advance toward the bioremediation of the shrimp culture water. The microbial consortia collected from natural environments (TaM) was constituted by bacteria (55.6%), Cyanophyte (18.4%), diatoms (9%), nematods (5.6%) and Chlorophyte algae (1.4%) among the major taxonomic groups. The removal of nutrients and solids by these mats was assessed in a recirculating system (2 cycles/hour) (n = 3) containing 60 and 120 ind m -2 of Litopenaeus vannamei. Results showed that the microbial mat reduces daily up to 71% of ammonia nitrogen, decreases around 68% of the biochemical oxygen demand (DBO 5 ) and up to 62% of suspended solids (SST) when comparing to the control systems (p < 0.05). By trapping organic and mineral matter, microbial mats have a clarifying effect on the water column. The mats effectively traps particulate matter and break it down with great efficiency due to the tight coupling between autotrophs and nitrifyers in the mat. This feature increases inorganic nitrogen levels in water column and accelerates nitrification up to 10 mg N-NO 3 -L -1 (120 ind m -2 ) producing 750% more nitrates than the control systems. Nevertheless, phosphorus removal was not significant (p > 0.05). The Bioremediated culture water had a positive effect on the culture of Litopenaeus
