The state of Assam in India is recognized as one the hotspots freshwater fish diversity. Beki River an important tributary Brahmaputra River. A significant decrease this region has been a major source concern recent years. diversity encountered various anthropogenic threats that have led to loss biodiversity. In study, was studied six landing zone and 31 species were recorded. ichthyofaunal bel...

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...

As new pathogenic strains are emerging and threatening aquaculture development, myxosporeans (Myxozoa) are receiving much attention in recent years. Myxosporean taxonomy is traditionally based on morphology of the myxospore stage. Molecular data on Indian myxosporeans are rare. In this report, the 18S rRNA gene sequence of Myxobolus cuttacki infecting gill lamellae of minor carp Labeo bata (Ham...

In the present study, we present normative ratings of free association for 139 European Portuguese (EP) words among 7- to 8-, 9- to 10-, and 11- to 12-year-old children attending the 3rd, 5th, and 7th grades of elementary and middle school in Portugal. For each word, five indices are presented: (a) the percentage of associates, (b) the strength of the first associate, (c) the strength of the se...

Effects of GABA-ergic agonists and antagonists were examined on the melanophores of a carp C. mrigala in vitro. GABA and baclofen both induced concentration - related dispersion in fish melanophores. Denervation of the melanophores by reserpine treatment potentiated the sensitivity of the melanophores to GABA. While denervation by cooling treatment inhibited the sensitivity of the melanophores ...

The effect of Spirulina supplementation on reduction of copper toxicity based on food utilization, phosphatases activities and selected haematological parameters was studied in a freshwater cultivable fish C. mrigala. Metal concentration in medium, body tissues and fecal matter was also analysed. Sublethal exposure of C. mrigala fed Spirulina-free diet significantly reduced the consumption and ...
