Good aquaculture practice (GAP) based carp fattening is a potential technique to obtain higher and safe fish production within shorter period in ponds of drought prone area. Sustainability this technique, however, constrained by high feed cost poor water quality. Therefore, as an overcoming effort, three diets (protein content 20%, 25% 30%) under different treatments (T1, T2 T3) were tested dur...

Field survey of Aquaculture farms in Basrah governorate was done during 2007. The study showed that there are 80 fish farm with total area 773.5 donum, while it 16 2003. 75 % the were less than 25000 m² (10 donum). 53.9 excavated pond, 34.2% concentration by half ground pools and 11.8 dyke pond. About 87.5 using pump 12.5 used tidal current for water supply. This 95 fishes source from Marine Sc...

The Sanandaj Gheshlagh Reservoir (SGR) is a mercury polluted lake that is located in the West of Iran. Common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix) are the most abundant fishes in the SGR. A total of 48 common and silver carps (24 each) were captured randomly, using 50×6 m gill net (mesh size: 5×5 cm) during July to December 2009. Each month, the levels of accumul...

Tc1-like transposons consist of an inverted repeat sequence flanking a transposase gene that exhibits similarity to the mobile DNA element, Tc1, of the nematode, Caenorhabditis elegans. They are widely distributed within vertebrate genomes including teleost fish; however, few active Tc1-like transposases have been discovered. In this study, 17 Tc1-like transposon sequences were isolated from 10...

Abstract Silver Carp Hypophthalmichthys molitrix have expanded their range to encompass most of the Mississippi River basin, including much Missouri River. However, there is a paucity information concerning in especially tributaries. Little known about how function these tributaries or connectivity with main‐stem river can influence population demographics within either system. The Kansas tribu...
