Biotic resistance is the process where aspects of the receiving environment inhibit the establishment and invasion of an introduced species. Resistance against an introduced fish can be through strong competition and/or predation from resident fishes. Here, the biotic resistance against introduced topmouth gudgeon Pseudorasbora parva (a highly invasive fish in Europe) by resident carp Cyprinus ...

Invasive species can cause substantial ecological impacts on native biodiversity. While ecological theory attempts to explain the processes involved in the trophic integration of invaders into native food webs and their competitive impacts on resident species, results are equivocal. In addition, quantifying the relative strength of impacts from non-native species (interspecific competition) ver...

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...

This study was carried out in Apa Dam Lake between January 2001 and December 2001. Characteristics of sexuality status, age groups, growth and reproduction as well as condition factor of Cyprinus carpio (L. 1758) population, which inhabits this dam lake and is of economic importance, was investigated. The age composition of Cyprinus carpio samples were determined to have ranged from I to VIII. ...

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...
