We examined how traditional farmers preserve the genetic diversity of a local common carp (Cyprinus carpio), which is locally referred to as "paddy field carp" (PF-carp), in a "globally important agricultural heritage system" (GIAHS), i.e., the 1,200-y-old rice-fish coculture system in Zhejiang Province, China. Our molecular and morphological analysis showed that the PF-carp has changed into a ...

Objectives: To describe trends in the use of coronary artery revascularisation procedures (CARPs) and to determine whether or when CARP rates will stabilise. Setting: State of Western Australia. Patients: All patients treated by coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) between 1980 and 2001. Design: Descriptive study. Main outcome measures: Age standard...

Fish are continuously exposed to multiple environmental stressors that work cumulatively and synergistically. This study assessed the stress responses of Indian major carps (IMCs) cultured in a sewage-fed pond (SP) East Kolkata Wetland (EKW), India compared with normal situ. The experiment was conducted two farms Labeo rohita, Catla catla Cirrhinus mrigala for seven months, covering summer wint...

background: anthropogenic activities release high concentrations of heavy metals into the aquatic ecosystems, which can be absorbed by the aquatic organisms. in this study, the accu-mulation of cadmium (cd) and arsenic (as) was compared in liver, gill and muscle tissues of toothed carp (aphanius sophiae) in fresh and salt water. methods: a total of 175 fish samples were collected from the shoor...

BACKGROUND The Australian federal government introduced private health insurance incentive policy reforms in 2000 that increased the uptake of private health insurance in Australia. There is currently a lack of evidence on the effect of the policy reforms on access to cardiovascular interventions in public and private hospitals in Australia. The aim was to investigate whether the increased priv...

Carps are the mainstay of Indian aquaculture, contributing over 90% to the total fish production, which was estimated to be 1.77 million metric tonnes in 1996. Carp culture has a great potential for waste utilization and thus for pollution abatement. Many wastes such as cow, poultry, pig, duck, goat, and sheep excreta, biogas slurry, effluents from different kinds of factories/industries have b...

The aim of the study was to investigate the physical difference in biochemical characteristics of spermatological and seminal plasma and also ultrastructure of spermatozoa in six carp species, viz. catla, Catla catla, rohu, Labeo rohita, kalbasu, Labeo calbasu, mrigal, Cirrhinus mrigala, silver carp, Hypophthalmichthys molitrix and grass carp, Ctenopharyngodon idella. Semen yield from different...

Invasive carps are ecologically and economically problematic fish species in many large river basins the United States pose a threat to aquatic ecosystems throughout much of North America. Four invasive carps: black carp (Mylopharyngodon piceus), grass (Ctenopharyngodon idella), silver (Hypophthalmichthys molitrix) bighead nobilis), particularly concerning for native because they occupy disrupt...

Continued on back page The most recent invasive species threatening Illinois’ aquatic ecosystems are the bighead and silver carps, two of four species commonly called Asian carps. These fish grow quickly to more than 50 lbs by consuming 30– 50% of their body weight each day in small algae and other tiny organisms. They also reproduce quickly and migrate long distances to spawn. Currently, in th...

As bighead carp Hypophthalmichthysnobilis and silver carp H. molitrix (the bigheaded carps) are poised to enter the Laurentian Great Lakes and potentially damage the region's economically important fishery, information on developmental rates and behaviors of carps is critical to assessing their ability to establish sustainable populations within the Great Lakes basin. In laboratory experiments,...
