The effect of ploidy on scale-cover pattern in linear ornamental (koi) common carp Cyprinus carpio was investigated. To obtain diploid and triploid linear fish, eggs taken from a leather C. carpio female (genotype ssNn) and sperm taken from a scaled C. carpio male (genotype SSnn) were used for the production of control (no shock) and heat-shocked progeny. In heat-shocked progeny, the 2 min heat...
A Myxobolus sp., morphologically resembling M. toyamai, M. longisporus, and M. koi, was isolated from the gills of a koi, Cyprinus carpio, that died in an ornamental pond. Large plasmodia were localized within lamellae, causing severe disruption of the normal branchial architecture, sufficient to compromise respiration. Although the case isolate shared several features with the aforementioned s...
Production potential of shingi, Heteropneustes fossilis and koi, Anabas testudineus in polyculture were assessed at a stocking density of 2, 47,000 and 3, 70,500 ha-1, respectively in treatment T1 and T2. Monoculture of H. fossilis and A. testudineus was designed at a stocking density of 2, 47,000 ha-1 in treatment T3 and T4, respectively. Culture period of shingi was 120 days and koi was 100 d...

Myxosporeans are best known for the diseases they cause in commercially important fish species. Identification of myxosporeans at the species-level is mainly based on conventional methods. The 18S rRNA gene sequence of morphologically identified Myxobolus orissae infecting the gill lamellae of mrigal carp Cirrhinus mrigala was characterized in the present study. The plasmodia of M. orissae were...
