Sažetak
Comparison of structure of gill filaments, red blood cells and olfactory epithelium between three - spined stickleback (Gasterosteus aculeatus) as marine fish and blue acara (Aequidens pulcher) as aquarium fish was analysed by scanning electron microscopy. Marine and aquarium fish gills look similar in their basic structure with tightly positioned lamellas. But on higher magnification, difference in surface structure of gill filaments can be noticed – surface of marine fish gills is covered with microvillous cells and surface of aquarium fish gills have concentring microfolds resembling finger prints. The difference in shape and size of gill rakers is also evident – sticklebacks' gills rakers are more elongated and peaked than rakers of aquarium fish gills. There are no major differences in size and general shape of red blood cells but young or immature red blood cells with bigger and more rounded nucleus were found. Olfactory epithelium and head structure with a lot of sensory – receptor cells were more interesting in marine fish. Two different types of sensory – receptor cells were found.
