Samples of Coelorinchus caelorhincus were collected by bottom trawl during MEDITS ("Mediterranean International Trawl Survey') in June 2003 in the northern and central Adriatic Sea. A total of 175 specimens of C. caelorhincus were used for analysis, of which 90 were males, 84 females and 1 indeterminate. Pre-anal length (PAL) in males ranged between 39 and 77 mm ((x) over bar =50.91 +/- 7.63 mm) and in females between 29 and 115 mm ((x) over bar =55.86 +/- 16.3 mm). The length-weight relationship for the whole sample was W=0.0004PAL(2.65) (r(2)=0.922) indicating negative allometric growth. The age structure of C. caelorhincus was determined from sagittal otolith readings. Maximum otolith length (LO) increased proportionally to fish length (LO=2.585+0.09PAL, r(2)=0.946). Age ranged from 2 to 8 years, with the majority of specimens being 3 (30%) and 4 (31%) years old. The von Bertalanffy growth parameters were: L(infinity)=128 mm, K=0.105 year(-1) and t(0) = -1.277 year.
