| food consumption of five deep-sea fishes in the balearic basin (western mediterranean sea): are there daily feeding rhythms in fishes living below 1000 m? | predation and food consumption of five deep-sea fish species living below 1000 m depth in the western mediterranean sea were analysed to identify the feeding patterns and food requirements of a deep-sea fish assemblage. a feeding rhythm was observed for risso's smooth-head alepocephalus rostratus, mediterranean grenadier coryphaenoides mediterraeus and mediterranean codling lepidion lepidion. differences in the patterns of the prey consumed suggest that feeding rhythms at such depths are linked ... | 2014 | 25052896 |
| development of multibank rod retinae in deep-sea fishes. | we studied the development of multibank rod retinae by monitoring the size-related addition of new layers of rod inner and outer segments in four species of deep-sea fishes and found two different growth paradigms. in the mesopelagic chauliodus sloani, new banks of rod inner and outer segments are added as long as the fish increases in size, as observed earlier by locket (1980). by contrast, in three bathybenthic species (antimora rostrata, corvphaenoides (coryphaenoides) guentheri, and coryphae ... | 2008 | 9685200 |
| rod outer segment renewal in the retinae of deep-sea fish. | outer segment renewal involves the synthesis of disc material in the photoreceptor inner segments, the shedding of the tips of the photoreceptor outer segments, and their phagocytosis by the retinal pigment epithelial cells. it has been suggested that in the retinae of deep-sea fish no renewal of outer segments may take place. in order to assess outer segment renewal in deep-sea fish retinae we counted (i) periciliary vesicles in rod inner segments as a parameter for disc-synthesis activity and ... | 1996 | 8917778 |
| patterns of rod proliferation in deep-sea fish retinae. | in a sample of 37 species of deep-sea fish species from the sea floor of the porcupine seabight and the gobal spur (north atlantic) we investigated the overall structure of the retina with special respect for the organization of rods, their length and their arrangement in multiple banks. using an immunocytochemical marker for cell proliferation (pcna) we studied the mechanisms of rod proliferation, and, by means of serial section reconstruction followed their integration into the existing popula ... | 1995 | 7660587 |
