Over het archief
Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.
Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

| Abstract |
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. |
