Phosphorus distribution in three crustacean zooplankton species
The distribution of phosphorus (P) was assessed in homogeneously 33P-labeled Daphnia magna, Daphnia galeata and Eudiaptomus gracilis. The specific P contents were 1.48, 1.41, and 0.50% of dry weight (DW), respectively. The results support the view of low intraspecific variability in P : DW ratios in crustacean zooplankton. The fraction of P allocated to nucleic acids, phospholipids, and other P...
متن کاملAnticholinesterase Effect of Eserine (Physostigmine) in Fish and Crustacean Species
The kinetic characteristic (Km) of cholinesterase from the crab Chasmagnathus granulata, the shrimp Farfantepenaeus paulensis and the fish Odontesthes bonaeriensis were compared and correlated with the anticholinesterasic effect of eserine (physostigmine). For the crustaceans, the estimated Km values were about 5-8 times higher than that estimated for the fish (0.04 mM). In the crab and the shr...
متن کاملOxidative stability of the hemolymph in different crustacean species
The aim of this study was to determine interspecies and gender differences in the lipid metabolism and hemolymph oxidation stability in intermoult period of the European spider crab (M. squinado), the warty crab (E. verrucosa) and the European spiny lobster (P. elephas). In hemolymph samples activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and paraoxonase 1 (PON 1), as ...
متن کاملFour parasitic Crustacean species from marine fishes of Turkey.
The aim of this work was to present a preliminary knowledge of the parasitic copepods of marine fish of Turkey. In this study, four parasitic crustaceans were reported from five different fish species found in Turkish seas: Lepeophtheirus europaensis (Zeddam, Berrebi, Renaud, Raibaut & Gabrion, 1988) was found on the gills of the European flounder, Platichtys flesus (Linnaeus, 1758 (Pleuronecti...
متن کاملPhotoreception in the planktonic larvae of two species of pullosquilla, a lysiosquilloid stomatopod crustacean
Optical microscopy, electron microscopy and microspectrophotometry were used to characterize pigments in the eyes of planktonic larvae of two species of the lysiosquilloid stomatopod Pullosquilla, P. litoralis and P. thomassini, which live sympatrically in French Polynesia. In contrast to the adult retina, which contains a diverse assortment of visual pigments in the main rhabdoms, the principa...
