Larval growth of anchovy, Engraulis encrasicolus (fishes) in the eastern Adriatic Sea

Engraulis encrasicolus were sampled in July/August 1990 in the Eastern Adriatic Sea, they were aged by means of growth rings in the sagittae. Length-age relationship was approximated by Gompertz and Laird-Gompertz functions with the high and statistically significant (P<0.001) correlation coefficient between estimated and observed values. Calculated values of Gompertz and Laird-Gompertz functions were a=29.66, b=3.03, c=0.012, L infinity=2.63, A=0.21, a=0.08. Statistically significant differences between the lengths estimated by the function obtained from growth rings counting and the lengths of artifically reared larvae of the same age suggest that the growth of larvae is affected by temperature and density of food. Growth parameters should be estimated for every particular survey when the data on age of larvae are needed.
