Ikan mas (Cyprinus carpio) merupakan jenis ikan air tawar budidaya paling penting, sehingga performa pertumbuhan diharapkan terus meningkat. Tujuan penelitian adalah untuk menganalisis induksi Bacillus CgM22 sebagai probiotik terhadap mutlak dan morfometrik villi usus pada carpio). Penelitian terdiri dari tahapan, (1) Pengambilan mikroba uji proteolitik, (2) Pemeliharaan Mas dengan oral melalui...

Ikan koi (Cyprinus carpio) merupakan jenis ikan hias air tawar yang banyak diminati oleh penggemar hias, sehingga memiliki peluang budidaya cukup baik. Kendala sering dihadapi pada adalah kualitas tingkat kecerahan warna masih rendah, menurunkan harga dan keinginan pencinta berpengaruh permintaan pasar. Salah satu cara dapat dilakukan yaitu meningkatkan nutrisi pakan hias. Tujuan penelitian ini...

determination of metal levels in muscle, liver and gill of common carp ( cyprinus carpio ) species caught from shirinsu wetland was done using icp-oes. the mean level of cu, pb and zn in muscle, liver and gill of fish were 0.01±0.002, 0.015±0.003, 0.007±0.001; 0.13±0.005, 0.006±0.001, 0.62±0.11 and 0.26±0.008, 0.009±0.002, 0.53±0.10 μg g −1 , respectively. metal levels in muscle were generally ...

The hematological parameters of the two-year-old carp (Cyprinus carpio) under combined stressed were studied. quantitative and qualitative deviations in blood composition found experimental group against control group. Neutrophilia, monocytosis lymphocytopenia identified as well an increased number young forms erythrocytes background stress factors.

in the present investigation a total of six parasite species, some eye-specific and others non-organ specific parasites were found in the eyes of 48 examined fish species, collected from fresh and brackish waters of iran during 2004-2006. ichthyophthirius multifiliis  was isolated from the external surface of the eyes of oncorhynchus mykiss, gyrodactylus stankovici from cyprinus carpio and lern...

White muscle strains were recorded using sonomicrometry techniques for 70 fast-starts in the common carp Cyprinus carpio L. High-speed cine images were recorded simultaneously for 54 of these starts, and muscle strain was calculated independently from the digitized outlines of the fish. Sonomicrometry measurements of superficial muscle strain were not significantly different from the strain as ...

Presently, aquatic pollution by ammonium compounds, due to their large scale production and the indiscriminate usage for the agriculture and aquaculture farms, has earned an important place among the environmental pollutants. Industrial effluents, bio degradation of waste products and food remains also contribute for the formation of considerable quantity of ammonia in the environment. Ammonia ...

A toy model of two dimensional nanoindentation in finite crystals is proposed. The crystal is described by periodized discrete elasticity whereas the indenter is a rigid strain field of triangular shape representing a hard knife-like indenter. Analysis of the model shows that there are a number of discontinuities in the load vs penetration depth plot which correspond to the creation of dislocat...
