- Information is presented on the occurrence of spinal deformities
in natural populations of grass goby, Zosterisessor ophiocephalus
(Pallas, 1811) in the Karin Sea, Eastern Middle Adriatic (44°09N-15°37E).
During 2002, the spinal deformity levels varied between 8.6% (in March)
and 20.9% (in May), and 16.5% in total catch. The spinal column is deformed
in one to few places from vertical to horizontal angles, and the deformities
are visible on the fish body immediately after catching. The possible
reasons for such deformities are discussed. |
