Sažetak
Sprat larvae collected in the Northern Adriatic (1995 and 1996) were used to estimate larval growth rates. Daily groth increments were counted on sagittal otoliths of 280 larvae (108 in 1995, and 172 in 1996) using transmission optical microscopy. Larval growth was estimated using the Gompertz and Laird-Gompertz growth curves for larvae ranging from 6.5 to 22.6 mm (1995) and from 6.9 to 22.5 mm (1996) in standard length. The largest growth increments were recorded for the 6-day-old (0.639 mm day-1) larvae in 1995, and for the 5-day-old larvae in 1996 (0.632 mm day-1). Mean growth rate was 0.421 mm day-1 (SD=0.169) in 1995, and 0.409 mm day-1 (SD=0.175) in 1996. There was no significant difference (P>0.05) in the rate of growth between years.
