| a comparative study of coi and 16 s rrna genes for dna barcoding of cultivable carps in india. | the 5' region of the mitochondrial dna gene cytochrome c oxidase subunit i (coi) is the standard marker for dna barcoding. however, 16 s rrna has also been advocated for dna barcoding in many animal species. herein, we directly compare the usefulness of coi and 16 s rrna in discriminating six cultivable carp species: labeo rohita, catla catla, cirrhinus mrigala, labeo fimbriatus, labeo bata and cirrhinus reba from india. analysis of partial sequences of these two gene fragments from 171 individu ... | 2015 | 24047160 |
| fishmicrosat: a microsatellite database of commercially important fishes and shellfishes of the indian subcontinent. | microsatellite dna is one of many powerful genetic markers used for the construction of genetic linkage maps and the study of population genetics. the biological databases in public domain hold vast numbers of microsatellite sequences for many organisms including fishes. the microsatellite data available in these data sources were extracted and managed into a database that facilitates sequences analysis and browsing relevant information. the system also helps to design primer sequences for flank ... | 2013 | 24047532 |
| hematological, biochemical and enzymological responses in an indian major carp labeo rohita induced by sublethal concentration of waterborne selenite exposure. | selenium (se) pollution in aquatic ecosystem is an environmental issue throughout the world. elevated concentrations of inorganic se from agricultural and industrial processes may cause adverse biological effects in aquatic organisms such as fish. in the present study, labeo rohita an indian major carp were exposed to sublethal concentration of se (sodium selenite) for 35days and certain hematological, biochemical and enzymological parameters were estimated. the median lethal concentration of wa ... | 2014 | 24183823 |
| present status and approaches for the sustainable development of community based fish culture in seasonal floodplains of bangladesh. | coordination among the different stakeholders at policy planning, implementation and target beneficiary level, particularly among the agencies responsible for development and management of water resources, agriculture and fisheries, is essential for overall sustainable development. stocking of larger fingerlings at suitable stocking densities of endemic (rohu, catla, mrigal) and exotic (silver carp, bighead carp, common carp/mirror carp) species should be stocked at varying proportion. floodplai ... | 2012 | 24191617 |
| impact of exotic carps in the polyculture with indigenous carps: competition for food. | the fingerlings of indigenous carps such as catla (catla catla), rohu (labeo rohita) and mrigal (cirrhinus mrigala) with exotic carps such as silver carp (hypophthalmichthys molitrix), bighead carp (aristichthys nobilis) and mirror carp (cyprinus carpio) were cultured together in a fish pond at bangladesh agricultural university, mymensingh, in order to determine the food electivity, dietary overlap and food competition among indigenous major carps and exotic carps. phytoplankton (chlorophyceae, ... | 2012 | 24191618 |
| identification and characterization of maturation-promoting factor from catfish,clarias batrachus. | maturation-promoting factor (mpf) extracted from maturing oocytes of catfishes (clarias batrachus andheteropneustes fossilis) and carp (labeo rohita) induces 100% germinal vesicle breakdown (gvbd) when microinjected intoclarias immature unstimulated oocytes. the presence of a similar mpf activity has also been demonstrated in the active fractions collected after superose 12. sds-page analyses of cytosolic extracts (ce) prepared from immature and mature oocytes revealed the presence of 34- and 46 ... | 1996 | 24194144 |
