NE Groundfish Survey S2021

S2021 was done without saving any lobsters but recording the data according to protocol.
1. No possibility of determining False(+)
2. Four files transmitted to JGK as a zip file quarantined to the kunkel home page directory on marlin.

Five strings of 10 trawls

Chi Square of ESD in 5 sequential strings of 10 trawls

Therefore, P[ESD is distributed evenly in the NE Groundfish Survey GoM territory] < 1% ... GoM ESD is clustered and could be classified as Epizootic.
