Age, growth and mortality of brown comber, Serranus hepatus (Linnaeus, 1758) (Pisces: Serranidae), in the eastern Adriatic (Croatian coast)

Age, growth and mortality were analysed for brown comber, Serranus hepatus, collected in the eastern Adriatic from May 2002 to June 2003. Fish aged 2-7 years were present in the samples. Growth in length including both sexes was expressed using the von Bertalanffy equation, L = 14.82, K = 0.217 and t0 = - 1.672. Age class 2, ranging in length from 5.8 to 9.0 cm TL, dominated the sample (29.3%). Total and natural mortality were Z = 1.73 year1 and M = 0.63 year1, respectively. The exploitation rate, E = 0.64, revealed a high fishing pressure on the stock in the studied area.
