Using natural extracts, as a source of anti-microbial, to improve the quality of fish is increasing. In this study, the ethanolic extract of orange (Citrus sinensis L.) was used due to having this property. Agar dilution method was employed in order to determine the minimum inhibitory concentration (MIC) of the ethanolic extract of orange peel on Pseudomonas aeruginosa, E. coli and Aeromonas hy...
Selenium is an essential element known to take part in human antioxidative defense and to protect against cardiovascular diseases and cancer. Consequently, supplementation of the diet with this element is necessary in order to achieve the protective effect. Several allium plants, radish etc have demonstrated the ability to preconcentrate and biotransform inorganic selenium into selenoaminoacids...
Suitability of herbal pesticides, turmeric and neem, in repelling dry fish insect Necrobia sp. adult
Repellency effect of turmeric and neem was investigated against the mite Necrobia sp. and field doses were determined on the basis of their repellency, keeping quality, insect occurrence and sensory evaluation of turmeric and neem treated dry fish and their cooked products. Turmeric and neem were used in three forms, viz., i. extract, ii. powder and iii. pellet. The concentrations tested for tu...
The effect of Persian bee propolis and pollen extracts on innate immune response of rainbow trout (Onchorhynchus mykiss) was investigated. Fish were fed diets containing 1% Pollen, 1% propolis and combination of the two immune-stimulants (0.5% Pollen and 0.5% propolis) as treatment groups and fed without the two immune-stimulants as positive and negative control groups for 4 weeks. The effects ...
Experimental fish were sprint trained by individual chasing for 30 s on alternate days for 9 weeks. Ten trained and 10 untrained animals were rapidly freezeclamped at rest and 0 ,1 , 3 and 6h after a 5-min chase. Swimming speed of 10 fish in each group was measured in a 2-min chase. Phosphocreatine (PCr), creatine, adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophospha...
OBJECTIVE To review the clinical features and laboratory investigations of ciguatera patients in Hong Kong between 2004 and 2007 in order to show the timely sampling of implicated fish from ciguatera victims and application of validated mouse bioassay for confirming suspected clinical cases of ciguatera. METHODS Diagnosis of the ciguatera victims was based on history of coral fish consumption...
Three different concentrations (10, 20 and 30 ppm) of the dry propolis and pollen extracts were applied in double distilled water. Biochemical and hematological parameters in blood of rainbow trout (Oncorhynchus mykiss) treated to various propolis and pollen concentrations (10, 20 and 30 ppm) for 96 h were determined. Fish treated to 20 and 30 ppm of propolis extract presented significant incr...
This study aimed at investigating the antibacterial effects of extracts from leaf, fruit, and stem of Solanum nigrum on fish pathogenic bacteria. The extraction process was done using the rotary device. The leaf methanol extract and the fruit acetone extract (MIC and MBC of 25 and 12.5 ppm, respectively) showed stronger antibacterial properties. The Streptococcus iniae were the most resistant b...
