Impact of different feeds on cannibalism in early larval stages Koi carp (Cyprinus carpio)K. Altaff and A. Janakiraman

Cyprinus carpio termasuk ikan yang bernilai ekonomis tinggi serta cukup diminati karena rasa enak dan daging lunak. Namun dalam usaha pembesarannya, ini membutuhkan ketersediaan pakan secara kontinyu, sehingga agar memperoleh keuntungan, pembudidaya harus berinovasi untuk mencari alternatif pakan. Tujuan penelitian adalah menguji efektivitas penggunaan tepung udang rebon (Acetes indicus) pertum...

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...

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...

Environmental DNA (eDNA) from aquatic vertebrates has recently been used to estimate the presence of a species. We hypothesized that fish release DNA into the water at a rate commensurate with their biomass. Thus, the concentration of eDNA of a target species may be used to estimate the species biomass. We developed an eDNA method to estimate the biomass of common carp (Cyprinus carpio L.) usin...

Various chemical and biological measures were determined in carp (Cyprinus carpio) sampled from seven sites along the Cuyahoga River, Ohio; from the relatively pristine headwaters to the lower portion heavily polluted from various industrial, urban and wastewater treatment plants (WWTP). Levels of nonylphenol (NP), nonylphenol ethoxylates (NPEs; NP1EO, NP2EO) and total NPEs (NP plus the NPEs) i...
