| Abstract: | This paper presents the results of investigations which were carried out in the Baltic Sea
in 1994 - 1995. The results show that cod length in catch depends on mesh sizes rather than on the
type of gillnet material. With mesh sizes of 45 mm (bar length) the average cod length in the catch
was 41 cm, while with a mesh size of 65 mm, the average cod length was about 53 cm. The results
of the investigation show that gillnets are characterized by very good selectivity; this is confirmed
by the selectivity coefficients that range from 3.9- 4.5. The by-catch of undersized cod specimens
was usually low for all analyzed gillnets. Most important, fishermen accept the present allowable
mesh size of 105 mm (mesh opening) in the cod gillnets and this mesh size is sufficient to protect
the cod of a total length of over 35 cm. |
