The boat names are abbreviated species of shark, where the shark name suggests another animal: frog shark, pigeye shark, etc. These tell you which animals to look at.
The phrase "rescue and salvage" refers to a class of ships in the US navy. This mini-meta's "feeder" answers are the names of ships. Each of these ships has a number within that ARS class. E.g., the USS Escape is ARS-6. Use these numbers to refer to letters in the alphabet. E.g., 6 means F, the sixth letter in the alphabet.
The ARS designations spell FON?IE. The answer is FONZIE (who has been known to jump a shark or two in his day). This means that the Tiger answer must be ARS-26, or SEIZE.
