Combined Effects of Seawater Temperature and Salinity on Development of the Larvae of the Rhizocephalan Peltogaster reticulatus (Crustacea: Cirripedia)

Combined Effects of Seawater Temperature and Salinity on Development of the Larvae of the... The effects of seawater temperature (12, 16, 20, 22, and 25°C) and salinity (of 8 to 34‰) in different combinations on the larvae of the rhizocephalan Peltogaster reticulatus (Crustacea: Cirripedia), a parasite of the hermit crab Pagurus proximus, were examined. The development of P. reticulatus is comprised of five naupliar stages and one cypris stage. Nauplii have a specific structure, the flotation collar encircling the dorsal side of the larval body. Larvae lack the pigmented nauplius eye, and they show no positive phototaxis. Successful naupliar development occurred in temperature and salinity ranges of 16–25°C and 20 to 34‰, respectively; but all nauplii died at 12°C and 16‰. The duration of each naupliar stage increased under lowering of the seawater temperature. At 22–25°C and 26–28‰, the entire development cycle was completed in 72–80 h; and at 16°C and 20‰ it lasted 153 h. The cypris larvae showed a greater resistance to decreased salinity in comparison with the nauplii. At temperatures of 16–25°C and salinities of 14 to 34‰, the lifespan of cyprids was 6 to 12 days, and it decreased at increasing temperature. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Marine Biology Springer Journals
