Determination of appropriate feeding schedules from diel feeding rhythms in finfish larviculture
Aquaculture, 2011Abstract In finfish larviculture, feeding regimes and schedules vary with hatchery and species. They have no biological or technological foundation and are dependent of operator expediency and previous experience. Inadequate feeding regimes and/or inappropriate food intake, especially during early larval stages, may result in a decline in health and ...

Diel feeding periodicity of two predatory stoneflies (Plecoptera)
Canadian Journal of Zoology, 1985Diel periodicity in feeding activity has not yet been established as a general pattern for predatory stoneflies. This study demonstrates by gut content analysis and behavioural observation that two predatory stoneflies, Kogotus nonus (Needham and Claassen) and Kogotus modestus (Banks) (Plecoptera: Perlodidae), do exhibit diel periodicity, but are not ...

Diel Patterns of Feeding in Heteropneustes fossilis from Southern Iraq
Transactions of the American Fisheries Society, 1977Abstract A study on the diurnal feeding cycle of the catfish, Heteropneustes fossilis (Bloch) from the Ashar Canal, Shatt-al-Arab at Basrah was carried out. The stomachs of the fish contained food almost throughout the 24-hour period. Both average index of fullness of the stomachs and the average points showed two peaks in the feeding cycle of the fish—

Copepod diel migration, feeding, and the vertical flux of pheopigments.
Limnology and Oceanography, 1989Feeding and diel vertical migration in the copepods Calanus pacificus Brodsky and Metridia lucens Boeck were examined during dusk and dawn in Dabob Bay, Washington. Both species migrated from below 75 m during the day into the upper 25 m at night. Feeding on phytoplankton was confined to periods spent in the surface layer.Metridia lucens arrived in the

Diel pattern of pelagic distribution and feeding in planktivorous fish
Oecologia, 1979The spatial distribution of juvenile roach (Rutilus rutilus), rudd (Scardinius erythrophtalamus), bream (Abramis brama) and bleak (Alburnus alburnus) was registered by echosounding during two years in small Bavarian lakes. The gut contents of the fish were analysed in order to reconstruct their rhythmicity of food intake. Fish were found in the pelagic

Aquaculture, 1996
The feeding rhythm and growth performance of European sea bass Dicentrarchus kzbrar (initial weight 65 g) were studied under free and time-restricted access to self-feeders. Under free access to the feeders, significant feeding rhythms with a nocturnal acrophase were observed, although there was considerable variability between replicates.

Diel feeding periodicity and daily ration of shelf break fish species
Journal of the Marine Biological Association of the United Kingdom, 2006The evaluation of the daily ration and feeding periodicity in a Mediterranean demersal fish assemblage under natural conditions is presented. Data were obtained during four trawl surveys conducted on the shelf-edge of the central Mediterranean Sea. Recently, researchers have begun to consider this area an essential fish habitat due to its extremely ...

Dietary composition and diel feeding patterns of epipelagic siphonophores
Marine Biology, 1981Prey consumption patterns are described for 24 species of epipelagic siphonophores studied during 1977–1980 in the Gulf of California, off Southern California, in the Sargasso Sea, and in Friday Harbor, Washington. Of the species, 7 were studied by day and at night, 15 were studied only by day, and 2 were studied only at night.
