Herrings are pelagic. The herring strains in the western Baltic probably spawn in an area
off the German coast in spring.
Figure 2.3.1 The silver eel migrate along the southern coast of the island of Lolland Falster in the
autumn. Commercial fishery for silver eel is common in the area.
Eel migrate through the area from September to November on their way to the Sargasso
Sea.
As a result of the fish studies at Rødsand, the probable migration and spawning
conditions in the area can be stated. These are shown in Table 2.3.1.

1) Daily migrations
2) Only intermediary, juvenile and spent (reference area) cod were recorded. The absence of any sexually mature cod is attributed
to the time of fishing (spawning season app. January to April)
3) Only intermediary, sexually differentiated, juvenile and spent flounder were recorded. The absence of any sexually mature
flounder is attributed to the time of fishing (spawning season April/early May).
4) Only few individuals were caught in the spring. A few were mature or had already spent.
Table 2.3.1. List of some important species recorded at Rødsand and location of their habitat as
either stationary or temporary (visitor). It is also shown whether the species probably
uses the area as a spawning area. (After bio/consult 2000a)
