An investigation was carried out to know the induced breeding techniques of some firewater fish species such as rui (Labeo rohita), catla (Catla catla), silver carp (Hypophthalmichthys molitrix), grass (Ctenopharyngodon idella), common (Cyprinus carpio), bighead nobilis), sharpunti (Puntius sarana) and bata bata) at Ma Fatima Fish Hatchery in Chanchra, Jashore, Bangladesh. The cost-benefit anal...

Fish larvae experience major cellular and biochemical changes during their early life stages.The aim of the present study was to evaluate alterations in the antioxidant status and values oflipid peroxidation and vitamin C content during the different life developmental stages ofHypophthalmichthys molitrix. Eggs and larvae were sampled at fertilization, organogenesis,eyed egg, hatch, active feed...

Using systemic, periodic surveys from 2015 to 2019, population distribution, speculated age and habitat preference were analyzed assess the living status for Silver Carp (Hypophthalmichthys molitrix) in lower Yangtze River. Small Carps became more temporarily abundant spring autumn, catch per unit effort (CPUE) fluctuated yearly. Spatially, going Anqing (AQ) Changshu (CS), 200 mm standard lengt...

Behavioral responses of silver carp (Hypopthalmichthys molitrix), bighead carp (H. nobilis), and common carp (Cyprinus carpio) to a complex, broadband sound were tested in the absence of visual cues to determine whether these species are negatively phonotaxic and the roles that sound pressure and particle motion might play mediating this response. In a dark featureless square enclosure, groups ...

An environment intensively studied from many perspectives, through the efforts of an interdisciplinary team of biologists, ecologists, geneticists, chemists, pedologists, etc. is Moara Domnească agroecosystem. Located in the North-East of Bucharest, the Moara Domnească Lake is used for irrigation of the neighbouring agricultural areas and also for pisciculture (Stavrescu-Bedivan et al., 2011). ...

Two species of common edible fish, common carp (Cyprinus carpio) and silver carp (Hypophthalmichthys molitrix), were exposed to a Microcystis spp.-dominated natural cyanobacterial water bloom for two months (concentrations of cyanobacterial toxin microcystin, 182-539 microg/g biomass dry wt). Toxins accumulated up to 1.4 to 29 ng/g fresh weight and 3.3 to 19 ng/g in the muscle of silver carp an...

Myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. The classification of myxosporeans is generally based on the morphology of their myxospores. Without molecular data, it is very difficult to identify new or existing species. DNA sequence information is therefore, a prerequisite to taxonomic and phy...

This paper describes seasonal changes of microcystin-LR (MC-LR) and its glutathione (MC-LR-GSH) and cysteine conjugates (MC-LR-Cys) in three aquatic animals--snail (Bellamya aeruginosa), shrimp (Macrobrachium nipponensis) and silver carp (Hypophthalmichthys molitrix) collected from Lake Taihu, China. MC-LR, MC-LR-GSH, and MC-LR-Cys were determined by liquid chromatography electrospray ionizatio...

The present study characterized Argulus spp. infecting the cultured carps using 18S rRNA gene sequences, estimated the genetic similarity among Argulus spp. and established their phylogenetic relationship. Of the 320 fish samples screened, 34 fish (10.6%) had Argulus infection. The parasitic frequency index (PFI) was observed to be high (20%) in Hypophthalmichthys molitrix and Labeo bata. The f...
