“…Epibenthic feeder species, together with G. longipes and P. alatus, displayed low levels of feeding activity (see Figure 5). All these species are relatively slow-growing, benthic macruran, brachyuran, and anomuran species with a highly calcified cuticle and long intermolt periods (Sarda et al, 1989). By contrast, more rapid-growing natantian decapods (pandalids, N. exilis, and A. antennatus), which have a poorly calcified cuticle (Sastry, 1983;Sarda et al, 1989), displayed a higher level of feeding activity.…”

Meso and bathypelagic natantian decapods, however, exhibited very low stomach fullness values as a result of pronounced feeding rhythms associated with diel vertical migrations (Lagardere, 1976a;Omori & Ohta, 1981;Roe, 1984).…”

Food resource partitioning and trends in feeding strategies were examined in 3882 individual decapod crustaceans collected from 1989 to 1990, using bottom trawls at depths between 380 and 2261 m in the Catalan Sea (western Mediterranean). The vertical distribution of available food resources near the bottom was the most important factor responsible for food resource partitioning among bathyal decapod crustaceans by depth stratum and season. Decapods were assigned to five different trophic groups according to the food resource exploited and feeding strategy employed (macroplankton feeders, macroplankton-epibenthic feeders, epibenthic feeders, epibenthic-endobenthic feeders, and deposit feeders). There was little dietary overlap, indicating that species did partition the available resources. Overall, dietary overlap values among species increased with depth. Although a trend to increase H’ values for diets with depth was observed, this was not significant (P < 0.10), whereas differences in the percentage of empty stomachs and the frequency of foraminiferans and pteropods in the foreguts increased significantly (P < 0.05) with depth. This last result is indicative of a progressive increase in the importance of deposit feeding in decapod crustaceans as depth increases.

“…Crustaceans have a high calcium content, which is located in the skeleton because calcium carbonate and Ca are generally cations that are abundant in the body [34]. Ca metabolism is related to life and reproductive strategies [57]. Ca concentrations generally vary in each aquatic ecosystem [40], so that low Ca concentrations can limit growth and production [58].…”

Crustacean carapace has various functions which can be seen from the composition of the biomaterial in it. Various concentrations of inorganic biomaterial elements were investigated from the hard carapace and the newly molted (soft-shelled) (Scylla paramamosain) with SEM-EDXRS (scanning electron microscopy-Energy Dispersive X-ray Spectrometer) technique. This study traced the composition of the inorganic elements of the premolt, postmolt, intermolt and soft (exuvium) crab hard carapace tissue of mangrove crabs from the point of view. Various stages of development. Important elements such as C, O2, Mg, P, Ca, S, Na, Si, Cl, and others, are reabsorbed from the carapace into the body tissues to fulfill further needs in soft-shelled crabs and are reused to some extent during formation new carapace. This study provides evidence that, inorganic elements in freshly molted soft carapace crabs are less common than hard carapace crabs

“…Eighteen of the lobster were taken from the inshore stocks of southern New England waters, ve were collected from offshore populations, and three 2.0 cm CL juveniles were obtained from the State of Massachusetts Lobster Hatchery. Sarda et al (1989) found that the growth rates of various crustaceans were affected by the degree of calci cation of the exoskeleton. Hence, a consistency of shell-hardness ( rm by feel) was maintained for lobster collected for this study.…”

This study was initiated to establish a relationship between carapace length (CL) and total surface area of the American lobster, Homarus americanus. Approximately 20,000 width and height measurements were taken at 0.5 or 1.0-cm increments along body parts of 26 healthy, intermolt, female lobster representing nine size-class groups, with CL in the range of 2.0 to 17.5 cm. Circumferences were calculated at each increment using the formula for the length of a parabolic arc. Surface areas between the increments were calculated by applying Simpson's Rule to the circumferences. The sum of these individual surface areas determined the total surface area of each lobster. The relationship between surface areas (cm 2 ) and CL (cm) was found to be modeled by the power function: y D 12:6889x 1:9677 , where y D total surface area for each lobster and x D carapace length.With reliable surface-area data, allometric relationships among eight body-part groups at various stages of lobster development were established and examined by ANCOVA methods. The slopes of the linear regressions of log 10 surface areas against log 10 CL for each of the eight body-part groups were tested simultaneously by ANCOVA methods and found to be heterogeneous. However, a complete, pair-wise ANCOVA analysis of these slopes revealed three clusters of body parts, each growing isometrically and with homogeneous slopes: (1) a central-core cluster, (2) an appendage cluster, and (3) a propulsion cluster. The propulsion cluster was formed from a statistical overlap of body parts between the core and appendage clusters.This work provided a formula for calculating total surface area for lobster based on a simple measurement of carapace length and, for the rst time, showed allometric relationships among body parts based on surface area for various size classes of the American lobster. This surface area formula currently is being used to develop a shell-disease severity index based on lesion area for lobster taken during an earlier study of shell-disease prevalence.
