“…A similar pattern was observed in M. tuxtlaense, an strictly freshwater prawn exposed to a salinity gradient (0,5,10,15,20,25, and 30 psu): higher rates of oxygen consumption in the shrimp M. tuxtlaense were observed at low salinities (0, 5 and 10 psu), to account for hyper-regulation of the osmolality of the hemolymph (Ordiano 2005). In the results of Moreira et al (1983) working with M. acanthurus, the oxygen consumption curve after 24 hours of exposure was dome-shaped, peaking at 21 psu. These results show that the metabolic response to variations in salinity is indeed variable in these decapod crustaceans, is dependent on the osmoregulatory history and strategy of the species, and is also time-dependent.…”

“…This apparent hyporegulation consists of a response of supression of the hyperegulation, strongly employed in freshwater, in these shrimps, and an still elusive salt secretion, possibly. The response may also be called a hypo-conformation, as in Moreira et al (1983) for M.acanthurus and other species of the genus. This strong tolerance to increases in salinity is in fact expected from the components of a clade that has invaded the freshwater relatively recently (Murphy and Austin 2005, Augusto et al 2007a, b, 2009, Pileggi and Mantelatto 2010, Collins et al 2011, McNamara and Faria 2012.…”

“…For instance, a decrease in the respiratory rate of the marine shrimps Marsupenaeus (Penaeus) japonicus (Bate, 1888) (Setiarto et al 2004), and Litopenaeus (Penaeus) setiferus (Linnaeus, 1767) (Rosas et al 1999), when exposed to a decrease in salinity, was observed. Some palaemonid shrimps exposed to salinity increases, for instance Macrobrachium heterochirus (Wiegmann, 1836) and Macrobrachium potiuna (Müller, 1880), experience a decrease in metabolic rates, while the diadromous Macrobrachium acanthurus (Wiegmann, 1836) and Macrobrachium olfersii (Wiegmann, 1836) experience a peak in their metabolism-salinity curves ("dome-shaped curve") close to their isosmotic point, ~21 psu (Moreira et al 1983). In another diadromous shrimp, Macrobrachium amazonicum (Heller, 1862), oxygen consumption was lower in freshwater than in 18 psu in zoea II, and was higher in freshwater than in 12 and 18 psu in zoea V (Mazzarelli et al 2015).…”

Oxygen consumption remains stable while ammonia excretion is reduced upon short time exposure to high salinity in Macrobrachium acanthurus (Caridae: Palaemonidae), a recent freshwater colonizer

ABSTRACT. Palaemonid shrimps occur in the tropical and temperate regions of South America and the Indo-Pacific, in brackish/freshwater habitats, and marine coastal areas. They form a clade that recently (i.e., ~30 mya) invaded freshwater, and one included genus, Macrobrachium Bate, 1868, is especially successful in limnic habitats. Adult Macrobrachium acanthurus (Wiegmann, 1836) dwell in coastal freshwaters, have diadromous habit, and need brackish water to develop. Thus, they are widely recognized as euryhaline. Here we test how this species responds to a short-term exposure to increased salinity. We hypothesized that abrupt exposure to high salinity would result in reduced gill ventilation/perfusion and decreased oxygen consumption. Shrimps were subjected to control (0 psu) and experimental salinities (10, 20, 30 psu), for four and eight hours (n = 8 in each group). The water in the experimental containers was saturated with oxygen before the beginning of the experiment; aeration was interrupted before placing the shrimp in the experimental container. Dissolved oxygen (DO), ammonia concentration, and pH were measured from the aquaria water, at the start and end of each experiment. After exposure, the shrimp's hemolymph was sampled for lactate and osmolality assays. Muscle tissue was sampled for hydration content (Muscle Water Content, MWC). Oxygen consumption was not reduced and hemolymph lactate did not increase

“…Os camarões palemonídeos tiveram sucesso ao saírem do ambiente ancestral marinho para habitar ambientes de água doce (JALIHAL et al, 1993), mas trabalhos realizados sobre a osmorregulação em camarões de água doce, demostram uma forte capacidade de hiper-osmorregulação em água doce e em baixas salinidades, perdendo essa capacidade em ambientes de alta salinidade (CASTELA; LAWREN-CE, 1981;MOREIRA et al, 1983;FREIRE et al, 2003). A maioria dos decápodas de água doce se tornam hipoconformadores em água com alta concentração de sal (MOREIRA et al, 1983;WILDER et al, 1998;SIGNORET;BRAILO-VSKY, 2004) ., 2003).…”

DUTRA, F. M.; FORNECK S. C.; BALLESTER, E. L. C. Suscetibilidade dos estágios ontogenéticos: padrão osmorregulatório em camarões peneídeos e palemonídeos. Arq. Ciênc. Vet. Zool. UNIPAR, Umuarama, v. 17, n. 3, p. 209-215, jul./set. 2014. RESUMO:A invasão da água doce por crustáceos ocorreu repetidamente ao longo dos anos, pressionando um ajuste em seus processos fisiológicos. A habilidade de sobreviver aos diferentes ambientes foi encontrada em traços osmorregulatórios, e estão relacionadas à capacidade de regular o fluido extracelular. Portanto, o objetivo deste manuscrito é explorar os processos osmorregulatórios de camarões palemonídeos e peneídeos, visualizando um padrão na capacidade osmorregulatória em ambas as famílias e, em particular, tratar de assuntos pertinentes aos efeito no ciclo ontogenético e o efeito ocasionado pelo nitrito na hemolinfa de crustáceos. Comparando palemonídeos e peneídeos, percebe-se que o sucesso da conquista do ambiente dulcícola, e a não necessidade de hiporregulação, levou à perda dessa capacidade na maioria dos palemonídeos. Dessa forma, se supõem um ancestral com capacidade hiporregulatória, uma vez que invertebrados marinhos são, parcimoniosamente, osmoconformadores. Compara-se também que o nitrito apresenta efeito nas proteínas presentes na hemolinfa dos crustáceos quando submetidos à exposição natural ou induzida deste composto, e que a capacidade osmorregulatória é, portanto, variada de acordo com seus estágios.

SUSCEPTIBILITY OF ONTOGENETIC STAGES: OSMOREGULATORY STANDARD IN PENAEID AND PALAEMONID SHRIMPSABSTRACT: The invasion of freshwater by crustaceans has occurred repeatedly over the years, pressing for an adjustment in their physiological processes. The ability to survive in different environments was found in osmoregulatory traits and is related to the ability to regulate the extracellular fluid. Therefore, the purpose of this manuscript is to explore the osmoregulatory processes in palaemonid and penaeid shrimps, which display a pattern of osmoregulatory capacity in both families and, in particular, to deal with matters related to the effects on ontogenetic cycle and the effect raised by nitrite in crustacean hemolymph. By comparing palaemonid and peneid shrimps, it is possible to note the success of conquering freshwater environment, and not the need for hypo-regulation, has led to the loss of this capability in most palaemonids. Thus, it is assumed that they share an ancestor with hypo-regulatory capacity, since marine invertebrates are sparsely osmoconformers. The article also compares that nitrite has effect on proteins present in the hemolymph of crustaceans when subjected to natural or induced exposure to these compound, and osmoregulatory capacity is therefore varied according to their stages.
