The BMI Lab is presently building Benthic Macroinvertebrate assessment models for New Brunswick's Water Classification Programme and a rapid BMI assessment tool linked to Water Classification for local community groups. In partnership with Environment Canada, they have developed the National online training programme for the Canadian Aquatic Biomonitoring Network (CABIN).  CABIN is a collaborative programme developed and maintained by Environment Canada for collecting, assessing and distributing information on the biological condition and biodiversity of aquatic ecosystems in Canada.



  • Taxonomic identification of benthic invertebrate samples.

  • Data analysis.

  • Data entry into the CABIN database.

  • Field sampling for benthic invertebrates.

  • CRI BMI Interactive key

Upon demand we may also provide digital imaging, sample dry and wet weights, and access to our taxonomic reference materials on hand, and easy access to additional resources available from the University of New Brunswick.

The following resources are available to NGOs and watershed groups to borrow from the lab:

  • Marchant Boxes

  • Full vacuum pump setup for subsampling

  • Tally counters

Fish Ageing

The Fish Ageing section of CRI Laboratory Services can provide technical services related to methods for ageing structure collection and subsequent lab analyses.  We have an Isomet 1000 precision diamond saw used to section calcified ageing structures.  Sections can be mounted onto slides to view using a microscope/fiche readers and/or digital imaging hardware and software.

CRI Laboratory Services has decades of experience collecting, identifying, and assessing fish health using life history characteristics such as those listed above (e.g. meristics, morphometrics, condition, maturity, sex, diet, parasite loadings and prevalence).

  • Ageing and age calculations for scales, otoliths, fin rays, opercula, and cleithra.


Quality Assurance and Quality Control (QAQC) Measures

Two or three readers read each set of samples of ageing structures.  The samples are read by an individual and then re-read blind.  Blind implies that the reader has no knowledge of the sample identification, size of fish, etc.  All samples are then read blind by a second reader. This means each sample is read three times.  The results are then used to provide an error rate associated with each sample and each project.  If the three results are not within the accepted error rate (CV < 10%), then the sample will go on for further independent verification and analysis

Fish Ageing Services
Service Structure Pricing/Sample
Age Only Scale $12
Age Analysis Scale $15
Age Only Otolith, cliethrum, operculum, fin ray $20
Age Analysis Otolith, cliethrum, operculum, fin ray $25
Digital Imaging All $8
Ageing only includes the preparation of the structure and ageing (by multiple people). Age analysis includes prep, ageing, and basic measurements for back calculating length at age. Please note, prices are subject to change based on turnaround time.
