Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods



  • Efforts were made to seek out and sample all littoral habitat types at each lake- silt-muck, sand, gravel-cobble-rock, organic detritus, logs and submergent and emergent vegetation. The littoral zone was sampled because it should yield the greatest number of species, the most valued fish food organisms, is less influenced by other natural limiting factors than the profundal zone, and was a zone common to all the lakes.
