Diel vertical migration of larval and early-juvenile burbot optimises survival and growth in a deep, pre-alpine lake

Comparison of continuous and discontinuous feeding regimens on the growth and survival of larval and early juvenile Atlantic sturgeon (Acipenser oxyrhynchus) under hatchery conditions

The influence of light on the diel vertical migration of young-of-the-year burbot Lota lota in Lake Constance.

The diel vertical distribution of young-of-the-year (YOY) burbot Lota lota in the pelagic zone of Lake Constance was compared to light intensity at the surface and to the light intensity at their mean depth. Lota lota larvae inhabited the pelagic zone of Lake Constance from the beginning of May until the end of August. From early June, after the stratification of the water column, fish performe...

Effects ofwater depth andhydrodynamics on the growth and distribution of juvenile cyprinids in the littoral zone of a large pre-alpine lake

In enclosure experiments in the littoral zone of Lake Constance, Germany, juvenile cyprinids showed significantly reduced somatic growth in the shallow eulittoral zone (0 5 m depth) compared to the sublittoral zone (1 6 m depth). Growth was especially reduced in larger and more deep-bodied fish groups, providing evidence that this is due to increased hydrodynamic stress, induced by ship and win...

Spatial and temporal patterns of verticaldistribution for three planktivorous fishes in LakeWashington

We sampled three limnetic fish species: juvenile sockeye salmon (Oncorhynchus nerka), three-spine stickleback (Gasterosteus aculeatus) and longfin smelt (Spirinchus thaleichthys) in Lake Washington to quantify species-specific patterns of diel vertical migration (DVM). Catch-per-unit-effort data analysed from 15 years of midwater trawling documented seasonal and diel differences in vertical dis...

Diet overlap between young-of-the-year perch, Perca fluviatilis L., and burbot, Lota lota (L.),during early life-history stages

The diet overlap between young-of-the-year (YOY) perch and burbot in the pelagic zone of Lake Constance during spring and summer was investigated in relation to gape size limitation. Because perch were larger and grew faster than burbot during their early life history, perch overcame gape size limitation for various zooplankton taxa earlier than burbot. The interspecific diet overlap between pe...
