A picking tray has been developed with the wet-picking of benthic foraminifera specifically in mind. The purpose is to reduce the primary disadvantage of the wet-picking method which is time consumption.
The wet-picking and counting of samples is seen to be disadvantageous in comparison with the dry method as it is more time consuming and arduous (e.g. Boltovskoy, 1966; Scott et al. 2001; Murray, 2006). However, wet-picking offers advantages over dry-picking. One major benefit is that it allows fragile forms (e.g. chitinous or poorly cemented tests) to be recorded that would be deformed or destroyed during drying (e.g. Brodniewicz, 1965). Depending on the scientific questions in focus, samples from certain environments should be wet-picked to prevent damage to thin-shelled forms and allow for a more accurate recording of the assemblage and diversity present (Bernhard & Sen Gupta, 1999). Furthermore the reduction of the protoplasm that results from drying means that detection of whether the protoplasm is stained or not can be more problematic (e.g. Corliss & Emerson, 1990; Bouchet et al. 2012). The cell (either stained or not) is more easily seen through the shell while wet, and Schönfeld et al. (2013) suggest that tests containing other stained material could be more easily mistaken for cytoplasm in dry samples. Therefore wet-picking also increases …
