How many orcas were involved in the Penn Cove capture?

During the infamous Penn Cove orca capture on August 8, 1970, over 80 wild orcas were herded into nets by captors to select animals for sale to marine parks — but only seven young orcas were ultimately taken into captivity, including Tokitae (Lolita). The rest were either released or escaped, and at least five orcas drowned in the nets during the operation.
