RALSTON ET AL.: BOTTOM FISH RESOURCE AT JOHNSTON ATOLL 



Table 2— Fishes encountered during dives (100-365 m) of the Makalii at Johnston Atoll. Included for each species are the minimum and 

 maximum depths (m) of observation as well as the median and range of the depth distribution. Under the sighting column a value of 

 1 indicates a species was seen repeatedly (>5 times) during each dive of the submersible, 2 means the species was occasionally seen 

 on each dive (<5 times), 3 signifies sightings on most dives but not all (i.e., species seen on several occasions), and 4 indicates rarity 

 (see only once or twice during all dives). An asterisk to the left of a species name signifies a new record for Johnston Atoll (Randall et 

 al. in press). 



nulatus, Acanthurus dussumieri, Zanclus comutus, 

 Xanthichthys auromarginatus, and Diodon hystrix. 

 These fishes accounted for an increase in diversity 

 at the 135 m dropoff. Similarly, due to the submer- 

 sible's 365 m depth limit, lower bounds for some 

 species are likely in error (eg., Symphysanodon mau- 



naloae, Epigonus sp., Pontinus macrocephalus, and 

 Satyrichthys engyceros). Nonetheless, due to the 

 large depth range sampled (100-365 m), the data still 

 provide useful estimates of the depth distributions 

 for most of the species listed. 

 The data suggest that large species have great
