The digestive physiology and stomach contents of six crab species from a variety habitats were investigated to provide an indication their capability dietary preferences. Stomach varied between species, but the key enzymes present generally consistent with types material being ingested. Nectocarcinus integrifons (red rock crab) consumed large quantities seagrass had high cellulase activity (0.02+/-0.004 units mg-1) digest constituent cellulose. Petrolisthes elongatus (porcelain ingested...
Abstract Catch predictions based on pre-recruit abundance have proven valuable in the stock assessment and management of major invertebrate fisheries Western Australia for western rock lobster (Panulirus cygnus), pearl oyster (Pinctada maxima), abalone (Haliotis roei), prawn (Penaeus esculentus), scallop (Amusium balloti), blue swimmer crab (Portunus armatus). Predictions are puerulus stage (post-larval) from artificial collectors; 0+ 1+ spat attached to commercial shell; dive survey Roe's...
The morphology and epithelial cytology of the digestive gland slipper lobster Thenus orientalis is described. primary ducts possess extensive musculature which indicate that they may move fluid into out glands. Immunohistochemical localization trypsin demonstrated it synthesized secreted solely by F-cells in gland. Trypsin absent from tissue oral region, proventriculus, hindgut, but present throughout alimentary tract, indicating has a role extracellular digestion. Substantial accumulations...
Concern for the sustainability of spiny lobster (Decapoda: Palinuridae) fisheries has created significant interest in their aquaculture. However, attempts to culture lobsters from eggs puerulus have been largely unsuccessful, hampered by provision unsuitable diets during long phyllosoma larval phase. This review summarizes current understanding feeding and digestive biology, collates findings previous trials. It draws attention gaps our knowledge suggests avenues future research aimed at...
Digestive capabilities of the commercially important slipper lobster Thenus orientalis were determined by comparing range and concentration digestive enzymes produced with preferred diet this other species. is a specialized predator bivalve molluscs, which are located probing digging substratum. The edible flesh removed wedging, progressive prying shell valves apart, using sharp keratinized pereiopod dactyls. reflects carnivorous T. orientalis. proteases trypsin chymotrypsin in high...
Mass balance estimates of carbon and nitrogen flux through two extensive shrimp ponds in the Mekong delta, Vietnam, were constructed to identify major sources sinks organic matter potentially available for production. Nutrient transformations sediments measured further assess rates decomposition burial quality matter. Tidal exchange was pathway inputs outputs both ponds, with net primary production, fixation precipitation being minor inputs. No fertilizers or artificial feeds added either...
Mouthpart and foregut structure indicates that Jasus edwardsii phyllosomas ingest soft fleshy foods such as gelatinous zooplankton. morphology changes little during larval development, indicating ingestive capabilities external mastication are well developed from an early age. However, the density complexity of setation robustness individual mouthparts increases with age, suggesting a greater capacity to larger prey development. The consists single chamber number well-developed grooves,...
