抄録

The results of a fishing survey on neon flying squid off Oregon and Washington states during August of 1990 are itemized as follows: 1) Most of the squids captured were females whose DML ranged from 25 to 60cm, 2) the relative growth equation of the female neon flying squid is W=0.026L^3.04, 3) good fishing ground was located in a warm water front and near an upwelled cold water area, whereas the water temperature ranged from 12.8 to 19.4°C at the surface and from 7.5 to 8.3°C at a abundant depth of 120m, 4) the angling depth ranged from 50 to 150m while most of the squids were caught at 120m. At depths ranging from 10 to 60m, thermocline was found, so this may be a considerable reason why neon flying squid could not break through this layer, and 5) the catch is greatly influenced by the duration of moonshine (H) during the night time. Big catches are found at drastically varying values of H.
