Fish communities differ significantly between the littoral and pelagic habitats. This paper attempts to define shift in two habitats based on European standard gillnet catch. We sampled benthic from shore Lake Most Římov Reservoir (Czech Republic). The 3 m deep nets were spanned across water body at equal distances boundary points, where depth was 3.5 m. community contained more fish, species, ...
HE sex determining mechanism in diploid Drosophila melanogaster is T completely stable. No intersexual individuals are produced from hybridizing strains of D. melanogaster collected from widely separated geographical localities. In Lymantria, on the contrary, GOLDSCHMIDT (1934) has shown that the potencies of the X chromosome sex gene differs in races from Europe and Japan. The degree of sexual...

The main objectives of this study were to study the parasitic infestation of Lernaea cyprinacea in 4 cyprinids from the Choghakhor Lagoon, Chaharmahal - Bakhtyari Province, west of Iran. A total of 180 cyprinids including Cyprinus carpio (n=101), Carassius auratus (n=47), Capoeta aculeata (n=10) and Alburnus alburnus (n=22) caught, and were studied for Lernaea cyprinacea infestation. Prevalence...
