He would take a sample of blood, for example, run DNA amplification (PCR) and then run a southern blot to detect for DNA patterns - then the various samples of blood/run gels can be compared to determine which whales are related to which, and which are separate families.

Hmmm...I can imagine you would use DNA fingerprinting to be able to distinguish individuals whales from one another. It wouldn't be too difficult to identify specific DNA markers where you could show relatedness to each other. These could be corroborated by visual observations. The real problem to using DNA fingerprinting here would be having to get a repeat sample later on to confirm the identities. Because of their migratory tendencies of certain whale species...this could be very difficult.
