Çipura (Sparus aurata L.) larvalarında otolitlerin günlük gelişimi

Bu çalışmada çipura larvalarının otolitlerindeki günlük gelişimler kontrollü şartlar altında yetiştirilen 1-65 gün arasındaki bireylerde gözlenmiştir. Günlük olarak alınan örneklerde standart boy ile iki farklı otolit türü sagitta ve lapillus boylan ölçülmüştür. Larva -boyu-sagitta boyu ve larva boyu-lapillus boyu arasında, power regresyon analizi sonucunda pozitif allometrik ilişki olduğu tespit edilmiştir. Otolit incelemelerinde günlük yaş halkalanda gözlenmeye çalışılmış ve sagittada olduğu gibi lapillusta da günlük halka oluşumunun mevcut olduğu görülmüştür.

Daily growh otoliths on gilthead sea bream (Sparus auruta L.) larvae

Daily growth ofotoliths on gilthead sea bream (Sparus aurata L.) larvae. In this study, daily growth of otoliths was observed on gilthead seabream larvae when 1-65 days old, under the controlled conditions. In daily sampling, standart length of larvae and two different otolith, sagittae and lapillus, lengths were measured. Power regression analysis was applied on determining the lengths of larvae between sagittae and lapillus. Result of the analysis, it was found a positive relationship, allometrically. It was also tried to determine the daily growth rings on otoliths and to be present of daily growth ring of lapillus as well as sagittae was also observed.
