Some of my lab mates have tried using clove oil to catch fishes at tide
pools before and it works beautifully. Clove oil acts as an anaesthesia and
temporarily knocks fishes out. Once they are placed in clean fresh seawater
again, they will regain consciousness after some time.
This method is good for hard to catch and cryptic fishes such as bennies and
gobies. We have got crustaceans before as well. However, the down side to
this method is, it is only effective in enclosed areas (eg tidal pools). It
won't work in the open seas or on reefs.
Usually clove oil is mixed with acetone in the ratio of 1:1 for the purpose
of catching fishes.

Clove oil is a powerful sedative on crustaceans. Don't know anything about
its use in the field, but understand photographers use it to sedate
crustaceans for professional grade, close-up photos because it sedates
without effecting color patterns (= motionless subject in full natural color
patterns). No idea what other effects might be, or how long the effect
