Grass carp reovirus (GCRV) is a causative agent of haemorrhagic disease in grass carp that drastically affects grass carp aquaculture. Here we report a novel GCRV isolate isolated from sick grass carp that induces obvious cytopathic effect in CIK cells and name it as GCRV096. A large number of GCRV 096 viral particles were found in the infected CIK cells by electron microscope. The shape, size ...

Previously we have shown, using two-dimensional electrophoresis, that mitochondrial ATP synthase (F(o)F(1)-ATPase) beta-subunit is the 55-kDa protein increased in cold-acclimated carp Cyprinus carpio (Kikuchi K, Itoi S, and Watabe S. Fisheries Sci 65: 629-636, 1999). To clarify the coordinate expression in various subunits of carp F(o)F(1)-ATPase with temperature acclimation, we examined the di...

Previously, we have established that a product of the doublecortin-like kinase (DCLK) gene, DCLK-short, is cleaved by caspases during serum deprivation. Subsequently, the N-terminal cleavage product of DCLK-short facilitates apoptosis in the neuroblastoma cell line NG108. As this N-terminal cleavage product is highly homologous to calcium/calmodulin-dependent protein kinase-related peptide (CAR...

Hornwort (Ceratophyllum demersum L.) and other aquatic macrophytes have historically been mechanically removed from the Rangiriri drain and Churchill East drain to maintain drain efficiency. As an alternative control method for the high plant biomass that accumulates at the end of summer, the effect of stocking diploid grass carp (Ctenopharyngodon idella L.) on the aquatic vegetation was evalua...

The prevention of non-indigenous aquatic invasive species spreading into new areas is a goal of many resource managers. New techniques have been developed to survey for species that are difficult to capture with conventional gears that involve the detection of their DNA in water samples (eDNA). This technique is currently used to track the invasion of bigheaded carps (silver carp and bighead ca...

Characteristics and functional efficacy of digestive proteases of Catla catla, catla, Labeo rohita, rohu and Hypophthalmichthys molitrix, silver carp were studied. Total protease activity was significantly (P < 0.05) higher in rohu (1.219 ± 0.059 U mg protein min) followed by silver carp (1.084 ± 0.061 U mg protein min), and catla (0.193 ± 0.006 U mg protein min). Trypsin activity of silver car...

The common carp (Cyprinus carpio) belongs to the family Cyprinidae. In nature, carp live in the middle or lower reaches of a river with slow currents, or in marshes. Their habitats are usually weedy areas with a muddy bottom. Carp fry feed on zooplankton such as rotifers and copepods, but as they grow up they become benthic feeders, feeding on animals and other organic material. The cyprinids h...

In the capacitated arc routing problem (CARP) there is a network of streets, and on a subset of streets we have to make services (e.g. winter gritting, litter collection, school bus scheduling). A fleet of identical vehicles of limited capacity provides services; the fleet is based at a depot and each trip starts and ends at the depot. Each street can be traversed any number of times, with a kn...

A high-resolution genetic linkage map is essential for a wide range of genetics and genomics studies such as comparative genomics analysis and QTL fine mapping. Crucian carp (Carassius auratus) is widely distributed in Eurasia, and is an important aquaculture fish worldwide. In this study, a high-density genetic linkage map was constructed for crucian carp using 2b-RAD technology. The consensus...

Recent work shows that the block-parallel CARP-CG algorithm [Parallel Computing 36, 2010] is extremely effective on sparse nonsymmetric linear systems with very small diagonal elements, including cases with discontinuous coefficients. In contrast to most known solvers, the effectiveness of CARP-CG often improves as the diagonal elements become smaller. This property is shown to follow from the ...
