background: antioxidant activities of plant extracts are being studied to increase the shelf life of fish products. some plants such as urtica dioica l. (nettle) can be a good source of antioxidants. the objective of this study was to evaluate the effects of hydroalcoholic and water extracts of nettle leaf on the chemical properties of superchilled minced meat of the common kilka fish (clupeone...

The use of bright coloration to warn predators of toxic prey, termed aposematism, is a defensive strategy well studied in terrestrial ecosystems. Some marine animals have contrasting color patterns and chemical defenses but few studies have tested the behavior of marine predators in response to aposematic coloration. In this study we tested fish feeding behavior in response to different types o...

This study evaluated the acute inflammatory response induced by carrageenin in the swim bladder of Nile tilapia supplemented with the mixture of natural extracts of propolis and Aloe barbadensis (1:1) at a concentration of 0.5%, 1% and 2% in diet during 15 days. Thirty-six fish were distributed into four treatments with three replicates: fish supplemented with 0.5% of admix of extracts of propo...

background and objectives: in the present study, isolation of streptomyces associated with marine sponges and its bioactive potential against fish and shellfish pathogens were assessed. the streptomyces sp. were isolated from the marine sponges namely callyspongia diffusa, mycale mytilorum, tedania anhelans and dysidea fragilis collected from vizhinjam port, situated in the south-west coast of ...

AIM The objective of this study is to gain a better understanding of the antimicrobial properties of the mucus extract of snakehead fish, Channa striatus against selected human and fish pathogenic microbes. MATERIALS AND METHODS The fish mucus samples were extracted with crude, acidic and aqueous solvents to identify potential antimicrobial agents including aqueous and acid soluble compounds....

eight medicinal plants were assessed for antimicrobial activity against lactococcus garvieae isolate obtained from diseased oncorhynchus mykiss collected from rainbow trout fish farms in iran. lactococcus garvieae is among the major pathogens of a large number of fish species cultured in fresh and marine recirculating and net pen production systems. the antibacterial activity of the medicinal p...

fast development of aquaculture and increasing fish demand lead to intensification of fish culture, magnifying stressors for fish and thus heightening the risk of disease until now, chemotherapy has been widely used to prevent and treat disease outbreaks, although use of chemical drugs has multiple negative impacts on environment and human health e.g. resistant bacterial strains and residual ac...
