You can purchase both measuring boards and sample bags, that we use when sampling fish, directly from us. The measuring boards are made of plastic with millimeter lines. The sample bags are designed for biological samples such as otoliths and fish scales, and are made of special archival paper with pre-printed data. Contact us to make your order!

Paper bags for biological samples 

We store our biological samples, such as otoliths and fish scales, in bags of acid-free paper that do not degrade or affect the samples. The bags are 40 x 75 mm in size. The bags are available with or without print (fill-in information about the sample).
