“…A higher oxygen consumption rate may indicate a higher energy requirement for osmoregulation under osmotic stress, reducing energy available for growth (Einarson 1993). The fasting and feeding oxygen consumption of P. vannamei']\ive.m\Q^ increases under low ambient salinity because more energy is diverted to maintain homeostasis (Rosas et al 2001). The scope for growth in the blue crab Callinectes similis juveniles is the highest at a salinity of 35 (Guerin and Stickle 1997b).…”

This study explored the survival and growth of the marine amphipod Hyaie crassicomis under different conditions of ambient temperature and salinity in the laboratory. In 96-h exposure experiments at a salinity of 30, //. crassicamis tolerated temperatures between 6 and 28 C C>90% survival). The 96-h LT50 value (median lethal temperature) at high temperature range for the amphipod was 32 C. The values at low temperature range for adults and juveniles were 3.2 and 4.2 C, respectiveiy, indicating that adults have a higher tolerance to low temperature than juveniles. At 25 C, the amphipods tolerated salinities between 10 and 50 (with >80% survival in 96 h). The 96-h LS^o values at high and low sahnity ranges were 56 and 2, respectively. Growth of the juveniles ft'om instars 1 to 6 was determined under different combinations of temperature and salinity. Growth rate of juveniles culrured at 25 C and a salinity-of 20 was the highest (0.114 mm day ') among the combinations of 15-25 C and 10-40 salinity. The moult increment of body length was afFected by both temperature and salinity. Yet the intermoult duration ofthe amphipods was affected by temperature only but not by salinity.

“…It seemed that the activity of glucose in muscle under salinity stress was lower than that in seawater because in low salinity, most carbohydrate needed in muscle comes from protein as it is the main site for gluconeogenesis (Rosas et al . ). This may be one reason why shrimp have low growth under low salinity (Diaz & Farfan ).…”

“…The relative expression value of GLUT1 increased with the increase of dietary carbohydrate level in hepatopancreas, gill and eyestalk which indicated that the glucose transport was increased with the increase in dietary CHO level under low salinity stress. It seemed that the activity of glucose in muscle under salinity stress was lower than that in seawater because in low salinity, most carbohydrate needed in muscle comes from protein as it is the main site for gluconeogenesis (Rosas et al 2001b). This may be one reason why shrimp have low growth under low salinity (Diaz & Farfan 2001).…”

Facilitative glucose transporter 1 (GLUT1) is a transporter protein for glucose transport via the plasma membrane of the cells to provide energy through carbohydrate metabolism. GLUT1 cDNA from Litopenaeus vannamei was obtained and analysed in this study. Full-length GLUT1 cDNA is 2062 bp long and contained a 1506-bp ORF encoding a 502 amino acid protein, a 270-bp 5 0 UTR and a 284-bp 3 0 UTR. When shrimp were under acute low salinity stress, the expression in hepatopancreas, muscle, gill and eyestalk was all up-regulated at 12 h (P < 0.05) and 96 h (P < 0.05), while the expression in the four tissues was all down-regulated at 6 h (P < 0.05) and 48 h (P < 0.05) . The expression in the muscle of shrimp at water salinity of 3 was lower than that at water salinity of 30 independent of dietary carbohydrate levels, while expression in hepatopancreas, gill and eyestalk was up-regulated at 200 and 300 g kg À1 carbohydrate levels. The expression in all tissues fed glucose was up-regulated when compared to the expression in shrimp held at a water salinity of 30. This study suggests that GLUT1 is a conserved protein in L. vannamei, and changes in expression due to environmental salinity and dietary carbohydrate level and source.

“…Although cyanobacteria naturally compete with algae in aquaculture tanks, cyanobacteria often dominate eutrophic tanks due to their higher ability to thrive with low dissolved oxygen, high temperature, and turbidity [56]. Moreover, the water salinities commonly used in shrimp ponds are optimal for N. spumigena growth [49,[57][58][59]. Therefore, cyanobacteria may form blooms in these environments and negatively interfere with shrimp production [60].…”

The bloom-forming cyanobacterium Nodularia spumigena CENA596 encodes the biosynthetic gene clusters (BGCs) of the known natural products nodularins, spumigins, anabaenopeptins/namalides, aeruginosins, mycosporin-like amino acids, and scytonemin, along with the terpenoid geosmin. Targeted metabolomics confirmed the production of these metabolic compounds, except for the alkaloid scytonemin. Genome mining of N. spumigena CENA596 and its three closely related Nodularia strains—two planktonic strains from the Baltic Sea and one benthic strain from Japanese marine sediment—revealed that the number of BGCs in planktonic strains was higher than in benthic one. Geosmin—a volatile compound with unpleasant taste and odor—was unique to the Brazilian strain CENA596. Automatic annotation of the genomes using subsystems technology revealed a related number of coding sequences and functional roles. Orthologs from the Nodularia genomes are involved in the primary and secondary metabolisms. Phylogenomic analysis of N. spumigena CENA596 based on 120 conserved protein sequences positioned this strain close to the Baltic Nodularia. Phylogeny of the 16S rRNA genes separated the Brazilian CENA596 strain from those of the Baltic Sea, despite their high sequence identities (99% identity, 100% coverage). The comparative analysis among planktic Nodularia strains showed that their genomes were considerably similar despite their geographically distant origin.
