Fish rhabdoviruses are harmful single-stranded RNA viruses with high mortality rates which cause considerable economic losses in aquaculture. It is imperative to explore and develop new antiviral compounds against them. In recent years, addition inorganic substances, more than 50 different organic have been confirmed be effective the prevention treatment of rhabdovirus infection its disseminati...

Chick poisoning induced by oral administration of toxic fish tissues or extracts gave rise to internal hypersalivation, decrease in weight and acute motor ataxia. Detoxification was low and repeated administration therefore led to toxin accumulation. Response of the chicken to liver feeding was roughly quantitative; so liver, which is the most potential toxic tissue, may be used for a preventiv...

BACKGROUND Fish processing is a common economic activity in Southern Africa. The aim of this study was to determine the prevalence and host determinants of allergic symptoms, allergic sensitization, bronchial hyper-responsiveness and asthma among workers processing saltwater fish. METHODS A cross-sectional study was conducted on 594 currently employed workers in two processing plants involved...

Abstract World population is increasing at a tremendous rate so the demand for animal-based protein. Aquaculture promising industry that has potential to supply high quality protein mankind with minimum environmental impact. In past decade, aquaculture practices have been shifting from extensive intensive culture. To achieve maximum production per unit area, stocking densities are maintained in...

The estuarine genus Pfiesteria has received considerable attention since it was first identified and proposed to be the causative agent of fish kills along the mid-Atlantic coast in 1992. The presumption has been that the mechanism of fish death is by release of one or more toxins by the dinoflagellate. In this report, we challenge the notion that Pfiesteria species produce ichthyotoxins. Speci...

Fish collected after a mass mortality at an artificial lake in south-east Queensland, Australia, were examined for the presence of nodularin as the lake had earlier been affected by a Nodularia bloom. Methanol extracts of muscle, liver, peritoneal and stomach contents were analysed by HPLC and tandem mass spectrometry; histological examination was conducted on livers from captured mullet. Liver...

The protein extract of Etroplus suratensis (E. suratensis) collected from Bavanisagar dam was found to be effective against all tested organisms with an inhibition zone ranging from 0.2 to 1.9 mm. When the result was compared with standard antibiotic Streptomycin, a moderate efficiency was observed. In vitro, an antibacterial assay was used to assess the efficacy of fish protein in inhibiting t...

A nested reverse transcriptase (RT) PCR assay detected mRNA of the salmonid pathogen Renibacterium salmoninarum in samples of RNA extracts of between 1 and 10 cells. Total RNA was extracted from cultured bacteria, Atlantic salmon (Salmo salar L.) kidney tissue and ovarian fluid seeded with the pathogen, and kidney tissue from both experimentally challenged and commercially raised fish. Followin...

This study evaluated extracts of Condalia buxifolia as anesthetics for the silver catfish Rhamdia quelen. The effectiveness of eugenol and of the methanolic extract (ME) of C. buxifolia during the transport of this species was also assessed. Fish of two different weights (1.50±0.02 g and 165.70±22.50 g) were transferred to aquaria containing water with the C. buxifolia ME or with fractions obta...

BACKGROUND Low-temperature techniques that prevent protein denaturation are being used to extract collagen from fish skin for cosmetic purposes. These extracts contain collagen with its triple helix structure preserved, as well as a number of other proteins. OBJECTIVES The aim of the study was to investigate collagen extracts from the skin of silver carp for the presence of small-molecule pep...
