1. Introduction A small-sized grass carp (43 cm long) was caught in Lake Whangape, lower Waikato River basin, in May 1997. This fish was too small to be a recapture from the escapement from trial sites in 1984 (fish which are now mostly longer than 70 cm), so could have been either a recent escapee, or the result of natural reproduction in the river. Either way, the finding of this fish indicat...

  Wild common carp of the Caspian Sea is one of the important fish in the north of Iran, which has been introduced to inland aquaculture. Its genetic characteristics are investigated to set up for breeding programs that are still unknown. Using wild common carp in aquaculture is limited for uncontrolled variation in performance of fish derived from undomesticated breeders. A 7×7 factorial matin...

Fish plays an important role in the Bangladeshi diet, constituting the main and often irreplaceable animal food in rural households. Fish consumption is dominated by wild small indigenous fish species (SIS). The vitamin A content in SIS varies from less than 100 to more than 2,500 retinol equivalents (RE) per 100 g of raw edible parts. This study assessed the dietary contribution of vitamin A, ...

BACKGROUND CARP-1/CCAR1, a perinuclear phospho-protein, regulates signaling by adriamycin, steroids, or growth factors. However, intracellular events that regulate CARP-1-dependent cell growth are not fully understood. RESULTS Here we investigated whether CARP-1 is involved in signaling induced by the protein kinase A inhibitor H89. Treatments of human breast cancer cells with H89 resulted in...

Distribution ! e common carp [Cyprinus carpio Linnaeus (1758)] has been one of the oldest domesticated species of fi sh for food. Culture of carp in China dates back to at least the 5th century BC, although domestication began much later. ! e European races of carp derived from wild carp of the Danube; the earliest attempts date back to the Roman Empire and spread of Christianity in Europe, fro...

Bid, BH3-interacting domain death agonist, is a pro-apoptotic BH3-only member of Bcl-2 family, playing an important role in apoptosis. In the study, Bid genes from grass carp (Ctenopharyngodon idellus) and rare minnow (Gobiocypris rarus), named CiBid and GrBid, were cloned and analyzed. Bid was constitutively expressed in all examined tissues of grass carp, but the expression level varied in di...

BACKGROUND Although the common, silver, and bighead carps are native and sparsely distributed in Eurasia, these fish have become abundant and invasive in North America. An understanding of the biology of these species may provide insights into sustainable control methods. The animal-associated microbiome plays an important role in host health. Characterization of the carp microbiome and the fac...

Species distribution models are valuable tools in studies of biogeography, ecology, and climate change and have been used to inform conservation and ecosystem management. However, species distribution models typically incorporate only climatic variables and species presence data. Model development or validation rarely considers functional components of species traits or other types of biologica...

Ten years ago, very little was known about the genetics of most of the cyprinid species of interest to aquaculture in Asia, for example the Chinese carps, silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis) and grass carp (Ctenopharyngodon idella); Indian major carps, catla (Catla catla), rohu (Labeo rohita) and mrigal (Cirrhinus cirrhosus); and the silver barb (Barbo...
