|| Data Analysis Issue
|| Observations from a single expert
|| “Charlie” recalls
schools of hundreds of paku‘iku‘i (Achilles
tang) in Kaloko in the 1960s, but for the last decade (1996 to 2006)
has counted no more than a dozen at any given time
||Observations from multiple experts
|| “Elaine” recalls
schools of hundreds of paku‘iku‘i in Kaloko
in 1960s, while “Barry” counts no more than one
dozen of the fish in the same area today (2006).
|| Quantitative abundance
|| “For decades we would
see between 10 and 13 lionfish on any given dive in that area.
Then, they all disappeared, and we haven’t seen one
|| “Yellow tang schools
were like rivers of yellow, or beds of yellow tulips until
the 1980s, then noticeably in decline until the late 1990s
when you might see two or four fish in any area”
|| Relative abundance (Indicating
a change catch per unit effort)
|| We used to go spearfishing
and all would choose a fish and only take that one kind of
fish. I’d take manini (convict tang) my friend
would take uhu (parrotfish)... There used to be so
many fish, I would have to push them out of the way to get
the one I wanted. After an hour, our lines would be full.
Now a couple of hours, and you get only a couple fish, different
kinds. Last week, I got in the water, and I was excited to
see one fish. Just one fish!”
|| Tinker’s butterflyfish
have been observed historically (1930s) from 5 to
180 feet depth. But for some decades adult Tinker’s
have not seen shallower than 100 feet. This is an indication
of a relative decline in distribution over space (shallow
depth range) and time (recent decades).
