Embryos, larvae, and adults of Palaemonetes argentinus tolerate a wide range of salinities (1 to 25‰). While osmoregulatory capacities have previously been demonstrated in all postembryonic stages, little is known about the occurrence of osmoregulation during the embryonic phase. We examined ontogenetic and salinity-induced changes in the activity of a key enzyme involved in osmoregulation, Na+...

Recent collections of pontoniine shrimps from Heron Island, southern Great Barrier Reef, have provided further additions to the Australian marine fauna. A new species, Periclimenes poriphilus sp. nov., is described and illustrated. It is the first species of its genus to be found actually in a sponge host. Several other Periclimenes species have been reported as associates of sponges. Periclime...

Osmoregulation was studied in the zoeal stages I and VI, the first decapodid, the first juvenile, and in adults of the palaemonid shrimp Palaernonetes argentinus. The larvae hatch in freshwater creeks or in adjacent brackish coastal lagoons of the warm temperate southwestern coast of the Atlantic Ocean; larval development is possible in low salinities. To cope with these demanding environments,...

Abstract Shrimp fisheries are one of the targets for local governments in designing and developing a marine protected area, especially East Aceh Regency. In general, efforts to preserve shrimp production requires information on larval distribution. The phase life cycle is essential continuing stock nature. This study aims analyse distribution larvae which become potential resources. was conduct...

A new species of pontoniine shrimp belonging to the 'Periclimenes obscurus species group' is described from the Berau Islands, North East Kalimantan, Indonesia. Specimens were obtained from aglaopheniid hydrozoans of the genus Macrorhynchia. The new species is here described and figured. Its affinities with related species are discussed and a DNA-barcode is provided.

Two new genera of crinoid-associated pontoniine shrimps, Brucecaris, new genus, and Unguicaris, new genus, are described and illustrated. Brucecaris is established for Periclimenes tenuis Bruce. Unguicaris panglaonis, new genus, new species, is described from crinoid-associated material collected at Panglao Island, Bohol Sea, The Philippines. Three species, Periclimenes alegrias Bruce, Periclim...
