Exploring Effects Of Sample Storage, Preparation, And Tissue Type On Fourier Transform-Near Infrared Spectroscopy (Ft-Nirs) Ageing Across Fish Taxa, Keith Fuller
Theses and Dissertations
The accurate determination of age for fish is a vital part of both populationmanagement and ichthyological research. However, the methods which are primarily employed to age fish can be difficult, time consuming, inaccurate, or some combination thereof. Most ageing is currently done via hard parts (such as otoliths, vertebrae, or scales) which are read in a manner similar to tree rings with markings corresponding to known or presumed periods of time. Recently, Fourier transform-near infrared spectroscopy (FT-NIRS) has been investigated as a novel tool to age fish more quickly and objectively. This method works by recording the vibrational frequencies of …
