Experiments were carried out on the survival and growth of Rasbora daniconius, Puntius ticto and Puntius conchonius. The motivation of the study was to obtain information for growing the fish on a commercial scale for their use as biological control agents against mosquito larvae. The effects of temperature, total hardness, DO, pH and feed on the growth of fish were also investigated. Excessive...

Interspecific androgenetic rosy barb (Puntius conchonius) was generated using its cadaveric (-20 degrees C) or fresh sperm to activate nuclear genome inactivated oocytes of gray tiger barb (Puntius tetrazona). UV irradiation was used to inactivate nuclear genome of tiger barb oocytes. Thermal shock restored diploidy of rosy barb in the oocytes of tiger barb. Survival of androgenotes was 14% or ...

The terminal Pleistocene and Early Holocene, a period from 15 000 to 18 000 Before Present (BP), was critical in establishing the current Holarctic fauna, with temperate-climate species largely replacing cold-adapted ones at mid-latitudes. However, the timing and nature of this process remain unclear for many taxa, a point that impacts on current and future management strategies. Here, we use a...

The water vole (Arvicola amphibius) in the forest-steppe of West Siberia is known to have wide fluctuations in abundance. These fluctuations are accompanied by changes in birth and death rates, sex-age structure of the population, and individual morphophysiological and behavioral characteristics of the animals. Survival of the animals depends on season, phase of population cycle, and sex. Based...

twenty spices were employed to preserve the cooked and uncooked fillet of puntius sarana (hamilton) and puntius ticto (hamilton). ic50 values of 2,2’-diphenyl-1-picrylhydrazyl(dpph) based free radical scavenging activity ranged from 0.1123 μg ml-1 in turmeric to 13.035 μg ml-1 in roman coriander. phenol content ranged from 0.365 μg g-1 in onion to 5.67 μg g-1 in clove. the raw and cooked fillet...

Anabas testudineus (2n = 46) had the more conserved pattern of its C-heterochromatin distributed mainly in the centromeric region, whereas Puntius sarana (2n = 50) exhibited a rather unorthodox pattern, many chromosomes showing interstitial, some telomeric and a few chromosomes showing centromeric C-band localization. Further, lateral asymmetry in distribution of heterochromatin was also noted ...

The medium-sized barbs (< 115 mm SL) hitherto referred to Puntius filamentosus (Valenciennes, 1844) in southern India and Sri Lanka are among the most common cyprinids in the lowland rivers and reservoirs of these areas. They form an important part of the local food and ornamental fishery (Pethiyagoda, 1991; Talwar & Jhingran, 1991), and are easily recognised by the elongated, filament-like ext...

This study describes the length-weight (LWR) and length-length (LLR) relationships of four cyprinid important small indigenous fish species (SIS) from the Padma River, Bangladesh. A total of 914 specimens were caught by traditional fishing gear from March 2006 to February 2007. Length (cm) and body weight (g) for each specimen was taken by a digital slide caliper and balance, respectively. The ...

Characterization of the helminth parasites of wild fish has a considerable importance from the point of view of hygiene and public health, as well as from its taxonomic interest. To study the pathogenecity of parasites in the field of fisheries, require detail knowledge of the parasites inhabiting localities involved. Present study aimed to investigate the intestinal nematodes from the Puntius ...
