The Fish on Fridays series is a collaboration between Gloucester photographers Kathy Chapman and Marty Luster. Look for various aspects of Gloucester’s centuries-old fishing industry highlighted here on Fridays.
This week we took a look at the longliner Iron Lady from Boston up for maintenance at Gloucester Marine Railways on Rocky Neck.
Longline fishing is a commercial fishing technique. It uses a long line, called the main line, with baited hooks attached at intervals by means of branch lines called snoods (or gangions). A snood is a short length of line, attached to the main line using a clip or swivel, with the hook at the other end. Longlines are classified mainly by where they are placed in the water column. This can be at the surface or at the bottom. Lines can also be set by means of an anchor, or left to drift. Hundreds or even thousands of baited hooks can hang from a single line. Longliners commonly target swordfish, tuna, halibut, sablefish and many other species.
In the third photo below, note the transponders that are deployed to insure finding the location of the line at any time.
