Age determinations were accomplished by examination of daily growth rings within otoliths. Age estimates were corroborated by growth experiments, analysis of a size-frequency distribution, and the determination of the onset of reproductive maturity. Estimates of the duration of the larval tholichthys stage were also obtained from study of the otoliths. The sex ratio of £. miliaris was 1:1 and individuals matured after one year of growth. The spawning season extended from November through Hay but peaked in February and March. No lunar influence on spawning was found. Estimates of fecundity were high and indicated a relatively large investment in reproduction. Chaetodon miliaris is broadly opportunitistic in its diet, however it feeds principally on zooplankton in the water column. The diet of individual fish varied as a function of the time of year, the collection location and the size of the fish. Individuals from Kaneohe Bay, Oahu, were small and appeared to be reproductively inactive when compared to fish from other areas. Dietary deficiencies are postulated as causing these differences. The overexploitation of populations of the millet-seed butterflyfish as a fisheries resource is improbable due to its fast growth, high fecundity, and the existence of refuge populations.

Feeding selectivity was tested in laboratory and field observations, with the fish clearly selecting M. verrucosa: 39:1 bites in laboratory trials and 284:1 bites in field observations. Using an estimated bite size of 2.54 mg AFDW and two estimated feeding rates, 4.88 bites min-1 during the "dry" season (May to September) and 7.20 bites min-1 during the "wet" season (October to April), an average sized fish consumes approximately 4000 g of coral tissue each year, and the population of C. unimaculatus on Patch Reef #42 is removing approximately 10% of the standing crop of M. verrucosa each year. A series of experiments was designed to measure the effect of predation by these fish on growth and competition between the two corals. Caged colonies of M. verrucosa at Patch Reef #42 had a vertical growth rate of 9.71 x 10-3cm day-1, and M. verrucosa killed P. compressa tissue it came in contact with. In uncaged colonies, M. verrucosa grew at a rate of 3.92 x 10-3cm day-1, about 40% of the caged growth rate, and several colonies showed a reversal of aggressive dominance as predicted from previous studies, with P. compressa killing branches of M. verrucosa. On Patch Reefs #42 and #43 there is a significant increase in the percent M. verrucosa with increased distance from the edge of the reef, where the fish are normally found, and grazing pressure is greatest. Because of its selective feeding behavior in Kane'ohe Bay, C. unimaculatus appears to have a significant effect on the growth and distribution of its preferred coral species, M. verrucosa.

It is a member of the goatfish family (Mullidae) and is endemic to Hawaii. One hundred and ninety-eight specimens, ranging in size from 31 to 306 mm, were collected from four areas around Oahu, Hawaii. Collections were made from July through November, 1968. The anatomy and the contents of the digestive systems were examined The digestive system is short. The stomach is V-shaped with a bulbiform pylorus. There are 20 pyloric caeca. The instestine has one siphonal loop. Transforming specimens differ in having a shorter, straight intestine. They also have sharper pharangeal teeth and longer gill rakers than do the adults. Occurrence of food in the entirA gastrointestinal tract was used in ranking relative fullness. These rankings, compared with time of capture, indicated feeding was nocturnal or crepuscular among larger fish (only very young kumu fed during the day) and that food passed through the alimentary canal within 19 hours. Twenty-three food items were identified; 12 of them occurred in >10% of the guts. Crabs were the most important food, followed by other crustaceans (copepods, isopods, other decapods) and other invertebrates. Sand occurred in 57% of the specimens. An extensive comparison of food items vs. fish size demonstrated various relationships. Although crabs were eaten by nearly all fish, only large kumu ate Stenopus and other fish, and only small kumu ate copepods and isopods.
