“…No food was provided before or during the experiments to avoid exogenous variation in oxygen consumption due to the digestion process, which is known to affect the internal metabolism (Ansell, 1973;Crear & Forteath, 2000). All of the measurements that refer to the individual animal's size (CL, mm), wet mass (WM, g), and body volume (mL, estimated by water volume displacement) were obtained at the end of the tests to avoid the effects of handling stress.…”

The effects of seasonal variation on the nutritional condition ofNephrops norvegicus(Astacidea: Nephropidae) from wild populations in the western Mediterranean

The Norway lobster, Nephrops norvegicus is a target fishery species in European waters. The stock assessment of N. norvegicus is complicated because it is caught in commercial gear only when it emerges from its burrow. Landings are lower in winter, and feeding limitations have been hypothesized as the cause. Wild large-sized male lobsters were sampled each season (winter, spring, summer and autumn), and two groups of animals were kept in captivity for 90 d (fed and fooddeprived). The hepatopancreas and muscle were dissected, weighted, frozen for biochemical analyses (proximal analyses and DNA/RNA) and fixed in Bouin solution for microscopic observations. The oxygen consumption rates in the wild individuals caught in the spring and in the captive animals after the treatments were measured. Significant differences among the experimental groups were observed in the lipid concentration of the hepatopancreas and muscle, the water content in the hepatopancreas, and the numbers of vacuoles and pyknotic nuclei in the cells of the tubules of the hepatopancreas. The results showed that the wild Norway lobsters generally presented intermediate values between those observed in the fooddeprived and the fed lobsters kept in captivity, but the values were closer to those obtained for the fed animals. This finding indicates that the wild animals exhibit a good nutritional condition throughout the year. Therefore, the wild males of N. norvegicus do not face food deprivation during winter as is suggested by the pattern of commercial catches, the flow of organic matter, and the moulting period/reproductive behaviour of the species.

“…Cardiac activity altered during exposure to 0.3 mg Hg l -1 , with heart rate increasing in each individual at times when it would normally have been expected to decline due to acclimatization and starvation (Ansell, 1973;Depledge, 1985). At lower exposure concentrations (0.1 mg Hg l -1 ) and in control conditions heart rate declined as expected.…”

SUMMARY: Heart rates were monitored in the pebble crab, Gaetice depressus using a non-invasive, computer aided cardiac monitoring system. A high degree of intra-and interindividual variability was observed, as was the presence of endogenous circatidal and circadian rhythms. Both acute and sublethal toxicities of mercury were determined. LC 50 's (96) for mercury were between 0.16-0.20 mg l ) resulted in rapid and statictically significant increases in heart rate whereas exposure to a concentration lower than LC 50 (96) (0.1 mg Hg l -1 ) resulted in progressive reduction in heart rate similar to that of control crabs.
