“…In hepatopancreas, total lipid ranged from 9.36 to 13.29%, comparable to values reported by González‐Félix et al (2002a) of 5.60–12.26%, or 5.16–10.42% (González‐Félix et al 2002b) also in salinity of 25 g/L. Palacios et al (2004a, 2004b) suggested that a low‐salinity environment may cause a lipid mobilization in shrimp to meet the requirements for energy imposed by osmoregulation, changing the lipid content as well as the fatty acid profile of cell membranes of gills, muscle, and hepatopancreas. This may explain the lower lipid content in muscle of L. vannamei observed at the end of this study at 4.10 g/L of salinity compared with the lipid content observed at the beginning, and because the DHA and ARA dietary requirement appears to be similar when this shrimp species is cultured at low or marine salinities, it is perhaps the total dietary lipid content the one that requires more attention to avoid a drastic lipid mobilization from muscle tissue to meet the energy demand imposed on shrimp by osmoregulation at low salinity.…”

A 3 × 3 factorial study was conducted to evaluate the effect of three fixed levels of docosahexaenoic acid meal (DHAM) and arachidonic acid meal (ARAM), produced by using a meal that had high levels of the desired fatty acid (0.23% DHAM–0.05% ARAM, 0.50% DHAM–0.10% ARAM, and 0.75% DHAM–0.15% ARAM), and three n‐3/n‐6 dietary ratios (0.3, 0.8, and 1.8), as well as their potential interaction on growth, survival, and fatty acid composition of hepatopancreas and muscle tissue of juvenile Pacific white shrimp, Litopenaeus vannamei, cultured in low salinity. Two additional reference diets with menhaden fish oil or soy and flax oils (n‐3/n‐6 ratios of 1.8 and 1.7, respectively) were tested. No significant differences (at P < 0.05) and no significant interactions were observed among treatments for final weight, weight gain, or survival after 6‐wk feeding. This study confirmed that supplementation of DHA and ARA from alternative sources to fish oil is effective in promoting growth and survival of juvenile L. vannamei. The fatty acid profile and n‐3/n‐6 ratio of shrimp tissue reflected that of dietary lipids, although more studies are required to elucidate how the n‐3 and n‐6 fatty acid balance in the diet relates to shrimp growth.

“…In crustaceans, the responses of the Na + /K + -ATPase enzyme as part of the adaptation of an animal to its environment has been extensively reported (Charmantier et al 2001;Péqueux 1995;Towle 1990;Towle et al 2001;Lin et al 2000;Palacios et al 2004). An increase of Na + /K + -ATPase activity occurs exclusively in the antennal gland rather than in gills and branchiostegite, in spite of their equal exposure to the external environment, supporting the function of the antennal gland and the enzymes therein in regulating the ionic balance of the hemolymph (Wheatly and Henry 1987).…”

Adaptation of the black tiger shrimp, Penaeus monodon, to different salinities through an excretory function of the antennal gland

et al. 2010

Black tiger shrimps (Penaeus monodon) are able to survive and can be reared under various salinities, possibly by the cellular adaptation of their excretory system, particularly the antennal gland, which is known to regulate body fluid in crustaceans. We have investigated the morphological and biochemical alterations of the antennal glands in shrimp reared in 7, 15, or 30 ppt seawater. Drastic changes occur in animals reared under 7 ppt conditions. Ultrastructural studies of the antennal gland in shrimps reared in 7 ppt seawater have revealed that podocytic cells in the coelomosacs ramify with more cytoplasmic processes forming the filtration slits, and that the tubular labyrinth cells possess more mitochondria in their basal striation and a wider tubular lumen than those found in the other groups. Many apical cytoplasmic blebs from labyrinth cells have also been seen in the lumen of the labyrinths under 7 ppt conditions, a feature that is not as prominent under the other conditions. The expression and activity of the Na(+)/K(+)-ATPase in the antennal gland are also correlated with the surrounding environment: the lower the salinity, the higher the expression and activity of the enzyme. Immunohistochemistry results have demonstrated the highest staining intensity in the labyrinth cells of shrimps reared under 7 ppt conditions. Our findings thus suggest that one of the adaptation mechanisms of this shrimp to the surrounding salinity is the regulation of Na(+)/K(+)-ATPase expression in the antennal gland, in conjunction with subcellular changes in its excretory cells.

“…The 96 h LC 50 values were 41 μmol/L and 362 μmol/L for L. vannamei at 5% and 25%, respectively [39] many previous studies have demonstrated that the optimal salinity for growth of L. vannamei should be around 20% [36,40]. When L. vannamei is exposed to dilute medium or low salinity, many problems such as the passive loss of Na + and Cl − will occur [41], and though L. vannamei could cope with these problems in different physiological ways [42], extremely low salinity is still a serious stress for L. vannamei. Therefore, lower mean LC 50 values of beta-cypermethrin and Acephate to white shrimp were observed at 5.0% when compared with those at 20.0% in the present study.…”

This study determined the lethal concentration values of betacypermethrin and Acephate to L. vannamei at two salinities (5.0% and 20.0%), and found that low salinity decreased the tolerance to these two pesticides in L. vannamei. Materials and Methods AbstractAcute toxic effects of two commonly used pesticides, beta-cypermethrin and Acephate, to the white-leg shrimp, Litopenaeus vannamei, were tested at ambient salinity 5.0% and 20.0%, by using a static renewal method. The results showed that the mean LC 50 values of beta-cypermethrin at 24, 48, 72 and 96 h were 0.437, 0.317, 0.203, and 0.170 μg/L to the white shrimp at 5.0%, and were 0.767, 0.440, 0.383, and 0.383 μg/L at 20.0%. The mean LC 50 values of Acephate at 24, 48, 72, and 96 h were 51. 250, 38.007, 27.783, 18.247 mg/L at 5.0%, and were 59. 853, 43.490, 34.220, 27.337 mg/L at 20.0%. L. vannamei is more sensitive to ambient beta-cypermethrin and Acephate toxicity at salinity 5.0% than at salinity 20.0%. Beta-cypermethrin is highly toxic to L. vannamei at either salinity, while acephate has low toxicity to L. vannamei.
