Penobscot Bay Pilot article on shrimp cites UMaine model

The Penobscot Bay Pilot article “Shrimp count remains low, depleted” mentioned a model developed by University of Maine researchers. The population of shrimp is still depleted and spawning stock biomass has been extremely low since 2013, according to the article. The 2018 stock assessment of the shrimp fishery investigated three models, with the preferred one being a statistical catch-at-length model created by Yong Chen, a UMaine professor of marine sciences, and his postdoctoral research assistant Jie Cao. The model divides northern shrimp stock into size groups and tracks changes in the proportion of shrimp in each group across seasons and years to produce estimates of fishing mortality and population size, the article states.
