Age, growth and length―weight relationship of Coelorinchus caelorhincus (Risso, 1810) in the Adriatic Sea

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...

description 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=50.91 plus or minus 7.63 mm) and in females between 29 and 115 mm (x=55.86 plus or minus 16.3 mm). The length-weight relationship for the whole sample was W=0.0004PAL super(2.65) (r super(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 super(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 sub( proportional to ) = 128 mm, K = 0.105 year super(-1) and t sub(0) = -1.277 year.Original Abstract: Uzorci morskog misa Coelorinchus caelorhincus sakupljeni su pridnenom povlacnom mrezom kocom tijekom ekspedicije MEDITS ('Mediterranean International Trawl Survey') u lipnju 2003. u sjevernom i srednjem Jadranu. Za analizu je spremljeno sveukupno 175 primjeraka C. caelorhincus od cega 90 muzjaka, 84 zenke i 1 nedeterminirani primjerak. Pre-analna duzina kod muzjaka kretala se u rasponu od 39 do 77 mm (x=50.91 plus or minus 7.63 mm), a kod zenki od 29 do 115 mm (x=55.86 plus or minus 16.3 mm). Duzinsko - maseni odnos za cjelokupni uzorak iznosio je W=0.0004PAL super(2.65) (r super(2)= 0.922) i ustanovljena je negativna alometrija. Starost C. caelorhincus je procijenjena ocitavanjem otolita. Maksimalna duzina otolita (LO) je proporcionalna duzini tijela (LO=2.585+0.09PAL, r super(2)=0.946). Starost se kretala od 2 do 8 godina, a vecina primjeraka bila je stara izmedju 3 (30%) i 4 (31%) godine. Von Bertalanffy parametri rasta iznosili su: L sub( proportional to ) = 128 mm, K = 0.105 godina super(-1) i t sub(0) = -1.277.
