| FISH Analysis | <molecular biology, technique> Use of a DNA or RNA probe todetect the presence of the complementaryDNA sequence in cloned bacterial or cultured eukaryotic cells.Also used for locating geneson chromosomes. The process is: Prepare microscope slide with cells in metaphase of mitosis, Treat slide with a weak base. Thus denaturing the DNA. Pour radioactively labelled probe onto the slide. Expose slide to photographic emulsion for a few days or weeks. Develop emulsion. (13 Oct 1997) |

| fish bowl granuloma | Localised nodular skin inflammation (small reddish raised areas of skin) caused by a bacterium called mycobacterium marinum. Fish bowl granuloma is typically acquired by occupational or recreational exposure to salt or fresh water, often resulting from minor trauma during caring for aquariums. The diagnosis is suggested by the history of exposure and confirmed by culturing tissue specimens which yield the microscopic organism, mycobacterium marinum. The infection can be treated with a variety of antibiotics, including doxycycline, minocycline, clarithromycin, rifampin, and trimethoprim-sulfamethoxazole. Also called swimming pool granuloma.

| fish diseases | Diseases of freshwater, marine, hatchery or aquarium fish. This term includes diseases of both teleosts (true fish) and elasmobranchs (sharks, rays and skates). (12 Dec 1998) |
| fish elevation | The elevation of a fish above the stream bed measured at the tip of the fish's snout. See: focal point. (09 Oct 1997) |

| fish flour | A flour made of pulverised, dried fish or fish parts. (12 Dec 1998) |
| fish habitat | The aquatic environment and the immediately surrounding terrestrial environment that, combined, afford the necessary biological and physical support systems required by fish species during various life history stages. (09 Oct 1997) |

| fish-mouth meatus | A red and swollen condition of the orifice of the urethra (urinary meatus) in gonorrhoea. Internal acoustic meatus, a canal running from the opening of the internal acoustic meatus, through the petrous portion of the temporal bone, ending at the fundus where a thin plate of bone separates it from the vestibule; it gives passage to the facial and vestibulocochlear nerves together with the labyrinthine artery and veins. Synonym: meatus acusticus internus, internal auditory meatus. (05 Mar 2000) |
| fish-mouth mitral stenosis | Extreme mitral stenosis. (05 Mar 2000) |
| fish-odour syndrome | <syndrome> An inborn error of metabolism associated with an offensive body odour, the smell of rotting fish, due to the excessive excretion of trimethylaminuria (TMA) in urine, sweat, and breath. Persons with TMA may experience tachycardia (fast heart rate) and severe hypertension (high blood pressure) after eating cheese (which contains tyramine) and after using nasal sprays containing epinephrine. TMA is caused by a mutation (change) in the gene for an enzyme, flavin-containing monooxygenase-3 (FMO3) encoded by a gene on chromosome 1. The FMO3 enzyme metabolises tyramine (which is in cheese). The syndrome is associated with various psychosocial reactions, including social isolation, clinical depression and attempted suicide. (12 Dec 1998) |
| fish oils | Oils high in unsaturated fats extracted from the bodies of fish or fish parts, especially the livers. Those from the liver are usually high in vitamin a. The oils are used as dietary supplements, in soaps and detergents, as protective coatings, and as a base for other food products such as vegetable shortenings. (12 Dec 1998) |
