Abstract
Reliable factory processing records of lobsters caught at all four islands of the Tristan group are available since 2001. These “pack category” data record the number of lobsters that fall into different packing categories. There are two types of product for
which data have been collected: “tails” (where only the tails are packed into cartons) and “whole” where either whole cooked or whole raw frozen lobsters are packed. The pack-categories however refer to certain weight ranges, with different categories
applying to “tails” and to “whole” product. Tables 1a and b list the pack categories
and the associated weight ranges.
