“…In these fish species, gill enzyme activity also followed a U-shape pattern with the environmental salinity, but the lowest value was found in water salinity close to the isosmotic point. Nevertheless, our results are in agreement with those reported for the rabbitfish Siganus rivulatus, where enzyme activity also followed a U-shape pattern across a wide range of water salinities with the lower values being observed in water salinities not close to that corresponding to the isosmotic point (14.6‰) (Saoud et al, 2007). Furthermore, it was shown that gill Na + ,K + -ATPase activity in the milkefish Chanos chanos did not show a clear pattern of change across salinities, with the lower enzyme activity value being found at 35‰.…”

“…Plasma osmolality, gill Na + ,K + -ATPase activity, whole body oxygen consumption and liver glycogen content are physiological parameters usually measured to evaluate the effect of salinity in fish (McCormick, 1995;Baldisserotto et al, 2007;Saoud et al, 2007). In fact, Na + ,K + -ATPase is the main enzyme responsible for NaCl transport across the teleost gills.…”

“…However, a slightly positive but not significant correlation (linear regression; b = 0.023; P > 0.05) between environmental and plasma osmolality was observed. This fact could be associated with a possible dehydration suffered by fish when exposed to hyperosmotic environments (Sampaio & Bianchini, 2002;Resley et al, 2006;Saoud et al, 2007). In fact, plasma osmolality in juveniles of the Lebranche mullet M. liza maintained at 5‰ (mean value: 473.4 ± 41.4 mOsmol kg ) (Nordlie et al, 1982;Nordlie, 2009).…”

“…This practice would imply that the energy saved in the absence of an important osmotic work could maximize fish growth (Boeuf & Payan, 2001;Saoud et al, 2007;Tsuzuki et al, 2007). However, this theory seems to be species-specific, since it has been proved for some fish species like Sparus sarba (Woo & Kelly, 1995), but not for others like Paralichthys orbignyanus (Sampaio & Bianchini, 2002).…”

Survival and physiological parameters associated with metabolism and osmoregulation were evaluated in juveniles of the Lebranche mullet Mugil liza acclimated to different water salinities (5, 10, 20, 30, and 40‰) for 15 days. Room temperature (25°C) and photoperiod (12L:12D) were fixed. Fish were fed twice-a-day with commercial diet (28% crude protein) until satiation. After acclimation, whole body oxygen consumption was measured and fish were euthanized and sampled for blood, gills, and liver. Whole body oxygen consumption and plasma osmolality did not change in the range of salinities tested. The isosmotic point was estimated as 412.7 mOsmol kg -1 (13.5‰). Gill Na + ,K + -ATPase activity tended to be lower at 20 and 30‰, while liver glycogen content was significantly higher at 20‰ than at 5 and 40‰. These results indicate that juvenile M. liza is able to acclimate for a short-period of time (15 days) to a wide range of salinities (5-40‰). This condition is achieved through adjustments in gill Na + ,K + -ATPase activity and carbohydrate metabolism to regulate plasma osmolality and aerobic/energy metabolism. Therefore, our findings support the idea of catching juveniles M. liza in sea water and rear them in estuarine and marine waters.A sobrevivência e parâmetros fisiológicos associados ao metabolismo e a osmorregulação foram avaliados em juvenis da tainha Mugil liza aclimatada à diferentes salinidades (5, 10, 20, 30 e 40‰) por 15 dias. Foram fixadas a temperatura (25°C) e o fotoperíodo (12L:12D) da sala onde os experimentos foram realizados. Os peixes foram alimentados duas vezes ao dia com ração comercial (28% de proteína bruta) até a saciedade. Após aclimatação, foi medido o consumo corporal de oxigênio e os peixes foram eutanasiados e foram coletadas amostras de sangue, brânquias e fígado. O consumo corporal de oxigênio e a osmolalidade plasmática não variaram na faixa de salinidade testada. O ponto isosmótico foi estimado em 412,7 mOsmol kg -1 (13,5‰). A atividade da Na + ,K + -ATPase branquial tendeu a ser menor em 20 e 30‰, enquanto o conteúdo de glicogênio hepático foi significativamente maior em 20‰ do que em 5 e 40‰. Estes resultados indicam que o juvenil de M. liza é capaz de se aclimatar a uma ampla faixa de salinidade (5-40‰) por um curto período de tempo (15 dias). Esta condição é atingida através de ajustes na atividade da Na + ,K + -ATPase branquial e no metabolismo de carboidratos para regular a osmolalidade plasmática e o metabolismo aeróbico/energético. Portanto, nossos achados suportam a ideia de que é possível capturar juvenis da tainha M. liza em água do mar e cultivá-los em águas estuarinas e marinhas.

The design of monitoring systems for marine areas has increased in the last years.One of the many advantages of wireless sensor networks is the quick process in data acquisition. The information from sensors can be processed, stored, and transmitted using protocols efficiently designed to energy saving and establishing the fastest routes. The processing and storing of data can be very useful for taking intelligent decisions for improving the water quality. The monitoring of water exchange in aquaculture tanks is very important to monitor the fish welfare. Thus, this paper presents the design, deployment, and test of a smart data gathering system for monitoring several parameters in aquaculture tanks using a wireless sensor network. The system based on a server is able to request and collect data from several nodes and store them in a database. This information can be postprocessed to take efficient decisions. The paper also presents the design of a conductivity sensor and a level sensor. These sensors are installed in several aquaculture tanks. The system was implemented using Flyport modules. Finally, the data gathering system was tested in terms of consumed bandwidth and the delay Transmission Control Protocol (TCP) packets delivering data from the sensors.
