Methods for making the 'podsicles' (an individual prey glued to a Zostera shoot tied to an acrylic rod) and deploying them in the field.
Prey include the most common amphipod, isopod, and gastropod species at your field site, as well as a standard prey (dried shrimp) and a mimic (green fuzzy pipe cleaner), with n = 24 for 120 individual podsicles per deployment.
This experiment should be repeated at least twice, ideally monthly, at each ZEN partner site.
Each run takes 3 field days: Day 1- collect prey, create podsicles. Day 2- deploy podsicles in the field. Day 3- collect podsicles and quantify prey survivorship.
See the ZEN 2012 handbook for more details.

Demonstration of how we sort our mesograzers here at VIMS using the nested sieves. Sieves are stacked from coarsest (top) to finest (bottom).
