Carps are the mainstay of Indian aquaculture, contributing over 90% to the total fish production, which was estimated to be 1.77 million metric tonnes in 1996. Carp culture has a great potential for waste utilization and thus for pollution abatement. Many wastes such as cow, poultry, pig, duck, goat, and sheep excreta, biogas slurry, effluents from different kinds of factories/industries have b...

Feral carps (Cyprinus carpio) were collected in spring 2001 from five sites along the lower course of Ebro River (Spain) with the aim of investigating the existence of endocrine-disrupting effects. Several findings (low gonadosomatic index (GSI), plasmatic vitellogenin (VTG), depressed levels of testosterone, and histological alterations in gonads) detected in male carps downstream of Zaragoza'...

In a territory-wide surveillance study, Laribacter hongkongensis was isolated solely from freshwater fish (60% of grass carps, 53% of bighead carps, and 25% of mud carps). Comparing the pulsed-field gel electrophoresis patterns of fish and patient isolates revealed that most patient isolates were clustered together, suggesting that some clones could be more virulent.

BACKGROUND Praziquantel (PZQ) is an effective pesticide against monogeneans. Its pharmacokinetics in fish may be affected by water environment and temperature. The present study was designed to compare the pharmacokinetics, tissue distribution, and elimination of PZQ in freshwater-acclimated grass carp and brackish water cultured grass carp. Plasma and tissue PZQ concentrations were determined ...

The gastrointestinal (GI) microbiome in fish plays significant roles health and disease resistance. This investigation was accomplished to enumerate, characterize identify the potential probiotic bacteria from three Indian Major Carps (IMCs), viz., rohu (Labeo rohita), catla (Catla catla) mrigal (Cirrhinus mrigala) using culture dependent methods. Altogether, 105 pathogen-inhibitory (out of 121...

We examined how traditional farmers preserve the genetic diversity of a local common carp (Cyprinus carpio), which is locally referred to as "paddy field carp" (PF-carp), in a "globally important agricultural heritage system" (GIAHS), i.e., the 1,200-y-old rice-fish coculture system in Zhejiang Province, China. Our molecular and morphological analysis showed that the PF-carp has changed into a ...

Since 1960s Community aquaculture gained its importance in India through the attempts of Research and Development agencies. Demonstration of fish culture practices in community ponds are challenged by its nature as water bodies are common property resources which requires substantial support from communities, local bodies and other agencies. Krishi Vigyan Kendra (KVK) Khordha, the Farm Science ...
