Whenever possible, live sharks are measured and a small monofilament tag is embedded just below the dorsal fin prior to release. Recaptures of these tagged sharks provide vital information about migratory patterns and growth rates. After the last hook has been taken out of the water the sharks are packed into ice and the deck is cleaned and prepared for the next set. Haul back can take 4-8 hours depending on the number of sharks captured. After the haul back, the crew is free to relax, bottom fish, and prepare for the next set.
Much consideration is given to the length of a trip.
Sometimes trips can be cut short when there are mechanical problems, not enough ice to keep the fish fresh, or a severe weather system moves into the area. Other limiting factors for a trip include fuel or groceries. Most trips are from two to eight days with an average of two sets per day. One of the benefits of spending the night at sea. Many times I have been asked what it is like to be a shark observer.
