hatching requirements of daphnia magna straus, 1820, and daphnia pulex linnaeus, 1758, diapausing eggs from iranian populations in vitro
considering the crucial importance of daphnia species in aquaculture, in particular for artificially- cultured sturgeon fry, a comprehensive study on the hatching requirements of their diapausing eggs seemed to be inevitable in order to obtain the ideal hatching technique. to do so, the ephippial eggs were collected from live food ponds in the cultivation and breeding centre of gorgan and after...
متن کاملLactate dehydrogenase activity as an effect criterion in toxicity tests with Daphnia magna straus.
Activity of lactate dehydrogenase (LDH) was used as an effect criterion in toxicity tests with Daphnia magna. In the first part of the work, the conditions for the use of LDH activity in toxicity tests with juveniles and adults of D. magna, were optimized. The influence of parameters such as the number of animals per sample, nutritional status, age and the presence of eggs in the brood chamber ...
متن کاملFreshwater microcrustacean Daphnia magna Straus as an early screen model to compare toxicity of acetylcholinesterase inhibitors
Daphnia magna is a freshwater microcrustacean which is often used for acute and chronic toxicity testing in aquatic ecotoxicology. Recently, tests with daphnids have been used to prescreen the toxicity of newly synthesized acetylcholinesterase reactivators (oximes), which appear as weak inhibitors of acetylcholinesterase (AChE). In our study we investigated and compared the toxicity of five rev...
متن کاملToxicity of sodium molybdate and sodium dichromate to Daphnia magna straus evaluated in acute, chronic, and acetylcholinesterase inhibition tests.
As a result of a widespread application in numerous industrial processes, chromium is a contaminant of many environmental systems. Chromium and their compounds are toxic to both invertebrates and vertebrates and, for this reason, there has been a search for suitable and less toxic alternatives. Molybdenum compounds have been studied as alternative to chromium compounds for some industrial appli...
متن کاملAquatic acute toxicity assessments of molybdenum (+VI) to Daphnia magna.
Generally, molybdenum (Mo) metals in the environment are very rare, but wastewater discharges from industrial processes may contain high concentrations of Mo, which has the potential to contaminate water or soil if not handled properly. In this study, the impact of three common compounds of hexavalent Mo (sodium molybdate (Na2MoO4‧2H2O), ammonium molybdate ((NH4)6Mo7O24‧4H2O) and molybdenum tri...
