Rotifers due to their relatively short lifespan, high fecundity and high rate of population growth are ideal for chronic toxicity tests. The aim of this research was to determine the lethal concentrations (LC50 24 h) of deltamethrin and imidaclopride and their impacts on the reproduction and growth of the freshwater rotifer, Brachionus calyciflorus. Experiments were carried out based on the gui...

First feeding of many fish larvae depends on live feed. A comparative investigation the effectiveness different types feed is not available to our knowledge. Hence, we conducted a study examine effect and combinations performance (survival rate, total length, body width, mass, malformation rate) pikeperch, Sander lucioperca, larvae. From day 0 (onset exogenous feeding) 10, saltwater rotifer Bra...
