Spatial and temporal distribution of fish and zooplankton in a shallow lake
(2003) In Freshwater Biology 48(8). p.1353-1362- Abstract
- 1. We performed both a large- and a small-scale echo sounding study on the spatial and
temporal distribution of fish (mainly roach, Rutilus rutilus and perch, Perca fluviatlis), as
well as a small-scale study of zooplankton distribution in the small, shallow and eutrophic
Lake Hanebjerg in Denmark. In the small-scale study, sampling was conducted in open
water as well as in the edge zone immediately outside two different types of vegetation.
2. Fish daytime abundances differed between the northern and the southern parts of the
lake and, on a small scale, small fish aggregated in the edge zones during day, preferably
outside dense emergent vegetation. Copepods avoided emergent... (More) - 1. We performed both a large- and a small-scale echo sounding study on the spatial and

lake and, on a small scale, small fish aggregated in the edge zones during day, preferably
outside dense emergent vegetation. Copepods avoided emergent vegetation, while
cladocerans showed no habitat preference. Both small fish and cladoceran numbers were
found to be higher during night than day.
3. The relative abundance (number per sample) of cladocerans in the edge zone
immediately outside vegetation was negatively correlated with the relative abundance of
fish in that zone. There was no correlation between cladoceran and fish abundance in open
water, or between the relative abundance of copepods and fish.
4. The presence of pelagic piscivores in combination with avoidance behaviour of both fish
and zooplankton is a likely explanation for the observed distribution of small fish and
cladocerans in Lake Hanebjerg. Both small- and large-scale distribution patterns may be
dependent on the type and distribution of complex structure in the lake. Even in a small
lake, large-scale patterns may affect the interpretation of small-scale data. (Less)
