| 内容記述 | NORPAC net (NP) and Remodeled NORPAC net (LNP) have been utilized for surveys of egg abundance as an indicator of spawning of pelagic fishes in the Japan Sea. Volume filtered (V:m3), plankton wet weight (W: mg) and the number of eggs of 4 fish species and a squid species taken in 36 single vertical tows ( 0 -150 m) of an eyeglass-shaped frame with a NP and a LNP around the Noto Peninsula were compared. While V in the LNP was significantly higher than in the NP (mean difference 9 %), W (per m3 or per haul) was significantly larger in the NP than in the LNP. However the number (per haul or per m2) of eggs of all species was not significantly different between the two net types. A comparison of ratios (LNP/NP) of the volume and the number (per m2) of the 5 species' eggs suggests that the variation in egg numbers are probably caused by the random or contagious distribution, and this has a greater impact on the egg density estimation than the differences between the net types. | |||||
