Sažetak:
The population dynamics parameters of scaldfish, Arnoglossus laterna, from the Adriatic Sea were studied. Specimens ranging from 4.5 to 17.1 cm in total length were collected from commercial bottom-trawl catches (2000-2006). The species spawns from April through the end of August, with a peak in May, and is one of usually present non-target species in mixed bottom trawl catches. The overall male to female ratio was 1.00:0.61. The oldest individual was 6 year old. The length-weight relationship showed positive alometric growth (b = 3.36 for males and b = 3.39 for females). The parameters of the von Bertalanffy growth equation were: L∞ = 17.3 cm ; K = 0.258 per year ; t0 = -1.0026 year ; R2 = 0.925. The relatively low value of total mortality (Z = 0.90) and relatively high value of constant rate of natural mortality (M = 0.64) was estimated. Eventually calculated fishing mortality (F = 0.26) and consequently estimated exploitation ratio (E = 0.29) indicated no danger of over exploitation of this species in the study area at current level of fishing pressure. The low T max and correspondingly high M suggest that this small benthic predator plays an important role in the Adriatic ecosystem as a prey species for large benthic predators. However, the estimates include uncertainties and require further confirmation, especially of the natural mortality.
