Preliminarna krivulja rasta i dužina tijela dobrih dupina Tursiops truncatus (Montagu, 1821) iz Jadranskog mora

The age of a sample of 20 bottlenose dolphins (Tursiops truncatus) (12 females, 7 males and one of unknown sex) was determined by counting the growth layer groups (GLGs) formed in the dentine. Preliminary growth rates for the bottlenose dolphins in the Adriatic Sea were established using the Gompertz equation and the Fishery Science Application Program. The growth curve derived was found to be similar to that of other Tursiops populations. Growth parameters, age of physical maturity and body length of a newborn specimen were also calculated. The preliminary data collected represent the first information on stranded dolphins found in the Croatian part of the Adriatic.Starost 20 dobrih dupina (Tursiops truncatus) (12 ženki, 7 mužjaka i jedan neodređenog spola) određena je prebrojavanjem zona prirasta (GLG – engl. »growth layer group«) formiranih u sloju dentina. Koristeći Gompertzovu jednadžbu i Fishery Science Application Program, izračunata je preliminarna krivulja rasta u vrste dobri dupin za Jadransko more. Krivulja rasta podudara se s krivuljama rasta iste vrste dupina u svijetu. Također su izračunati približna starost jedinki u kojoj se postiže fizička zrelost i približna duljina tijela mladunčadi. Podaci prikupljeni ovim radom preliminarni su i predstavljaju prvu informaciju o pronađenim uginulim dupinima u hrvatskom dijelu Jadranskog mora
