Abstract
Data on the nutritional status of spiny lobster (Panulirus marginatus)
were collected on the commercial trapping grounds of Necker Bank,
Northwestern Hawaiian Islands, in the summers of 1991, 1994, and 1995. Glycogen
levels measured in abdominal tissue of intermolt males were used as an
index of nutritional health of the field population. The range of glycogen
sampled from wild lobster was less than half the level measured in captive lobster
fed to satiation in a previous study. An analysis of covariance identified significant
interannual and spatial effects explaining 46% of the variance in the
sample of wild lobsters. Most significant was a decline in lobster glycogen levels
between samples collected in 1991 and 1994-1995. Seasonal influences on lobster
nutrition are unknown and were identified as an obvious direction for
future ecological research.
