They also create problems for oyster farmers by burying oyster seed, and have been widely regarded as pests. In the past, the pesticide carbaryl was used on mudflats to exterminate burrowing shrimp. While less toxic methods are currently used, it is important for the oyster industry to understand the population and age of burrowing shrimp in the ecosystem.

Patterns in strong recruitment years amongst estuaries, particularly for U. pugettensis, suggest the presence of multi-estuary metapopulations linked via larval dispersal. These results have important implications for shrimp population management including control for shellfish aquaculture, but also conservation of estuarine habitats due to the strong influence of these ecosystem engineers on the benthic community.{\textquotedblright} (from the Abstract)}, pages = {p.1848-1867}, keywords = {ecosystem engineer, Ghost shrimp = Neotrypaea californiensis (Callianassa californiensis), larvae, Mud shrimp = Upogebia pugettensis, population biology, settlement, Willapa Bay, Yaquina Bay}, doi = {https://doi.org/10.1007/s12237-018-0397-4}, author = {Dumbauld, Brett R. and Bosley, Katelyn M.} } @article {54871, title = {Isolation and characterization of novel microsatellite loci in two species of burrowing shrimp, Neotrypaea californiensis and Upogebia pugettensis}, journal = {Conservation Genetics Resources}, volume = {6}, year = {2014}, note = {The authors characterized 31 microsatellite loci for the two West Coast shrimp species. {\textquotedblleft}These are the first microsatellites characterized for these species and provide a useful tool for further characterization of population structure and diversity.{\textquotedblright} (from the Abstract)}, month = {2014, Jun.}, pages = {p.353-356}, keywords = {Bodega Bay, genetics, Ghost shrimp = Neotrypaea californiensis (Callianassa californiensis), Humboldt Bay, Mud shrimp = Upogebia pugettensis, Yaquina Bay}, doi = {10.1007/s12686-013-0092-5}, author = {Dumbauld, Brett R. and Mercer, Dacey M. and Camara, Mark} } @article {34531, title = {An introduced Asian parasite threatens northeastern Pacific estuarine ecosystems}, journal = {Biological Invasions}, volume = {14}, year = {2012}, note = {The non-indigenous isopod Orthione griffenis effectively castrates the mud shrimp Upogebia.
