Fish live in a medium that is an especially good conductor of sound, and the myriad extant species—some 25,000 in the class Osteichthyes (bony fishes) alone (Nelson, 1984)—have evolved diverse mechanisms for transducing acoustic stimuli. It should not be surprising if sophisticated functionality in the auditory domain turns out to be a major component of the perceptual and cognitive capabilitie...

Spontaneous swimming behaviors of koi carp Cyprinus carpio koi were recorded using a video tracking system. Routine single-beat turns were selected from the recorded image sequences for kinematic and hydrodynamic analysis. As with C-starts, the turns can be divided into two stages (stage 1 and stage 2), based on kinematics. Stage 1 involves a bend to one side forming a C-shaped curve in the bod...

A spontaneous seminoma in a 3 yr old male koi carp Cyprinus carpio L. is described. The animal, presenting a symmetric abdominal enlargement, showed a celomatic multinodular, white-yellowish and firm mass that infiltrated the liver and the intestine wall. Histologically, the neoplasm was non-encapsulated and poorly demarcated, showed invasive growth and was characterized by a lobular architectu...

Shigellosis is an important cause of morbidity and mortality throughout the world. Approximately, 1.1 million deaths occur a year due to this disease, making it the fourth leading cause of mortality worldwide. This paper explores local interest in and potential use of a vaccine for shigellosis in Thailand where Shigella poses an important public-health concern. Data for this study were collecte...

Abiotic factors of the water environment are essential for life hydrobionts. They determined by two main criteria – intensity impact factor and tolerance each species. The work aims to substantiate adaptive capabilities this summer's koi carp (Cyprinus carpio koi) under influence low high temperatures, compare coefficients breathing rhythms research objects. Experimental was carried out in cond...

MicroRNAs (miRNAs) are a class of small non-coding RNAs involved in post-transcriptional gene regulation. Some viruses encode their own miRNAs and these are increasingly being recognized as important modulators of viral and host gene expression. Cyprinid herpesvirus 3 (CyHV-3) is a highly pathogenic agent that causes acute mass mortalities in carp (Cyprinus carpio carpio) and koi (Cyprinus carp...
