Abstract
U radu su opisane najvažnije biološke značajke kovača, kao kozmopolitske vrste riba, na temelju dosadašnjih istraživanja. Kovač je gospodarski značajna vrsta, no njegove biološke osobitosti onemogućuju mu brzu obnovu populacija. Dužina prve spolne zrelosti nalazi se u rasponu od 25 – 35 cm što predstavlja najveći problem u stvaranju novih generacija. Ova veličina predstavlja prekretnicu u promjeni prehrane, s manje ribe i rakova na gotovo potpunu prehranu većom ribom. U većini istraživanja uočena je brojčana dominacija ženki, 1,6:1 što je pozitivna činjenica koja bi s adekvatnim mjerama mogla pomoći obnavljanju populacija ove vrste.
Abstract (english)
On the basis of the recent research this paper presents the most important features of John Dory, as one of the cosmopolitan fish species. John Dory is from a commercial point of view an important species, but its biological features don’t allow fast growth of its population. As each fish needs to reach a length of 25 – 35 centimetres before it can engage in its first reproductive cycle, the production of new generations is therefore slow. This size represents a turning point in nutrition change, with less fish and crustaceans to almost complete nutrition with larger fish. It’s interesting to note that majority of research records a greater number of females than males, with a 1.6:1 ratio. This is a positive fact which could, through adequate measures, help restore the population of this species.
