内容記述 | As a continuation of previous report (Matsuoka, 1995), comparative samples of fish eggs and larvae between the Marutoku B net (MTB-net) and the Remodelled NORPAC net (LNP-net) were undertaken. Experiments 1, 2 and 3 respectively were composed of 10 repeated hauls at 3 different sites in the spawning survey ground in the western waters of Kyushu. The volume of water filtered by the LNP-net was considerably higher than that of the MTB-net (average 34%) and the plankton wet weight/haul of the LNP-net was also significantly higher than that of the MTB-net. As for the catches of eggs and larvae, Experiment 1 showed only the number of fish larvae with the exception of the number of sardines/haul being significantly higher in the LNP-net. In Experiment 2, the number of sardine eggs was clearly higher in the LNP-net. Experiment 3 showed marked differences between the two nets. All catches of eggs and larvae between the MTB-net and LNP-net including the commercially important group "iwashi" (anchovy, round herring and sardine)/haul were significantly higher for the LNP-net, mostly at the 1% level. This experiment was done under calm conditions, and many gelatinous plankton caused net clogging. The spawning survey is sometimes conducted in more plankton-rich conditions, so the present results indicated that nets having a high open area ratio, like the LNP-net, should be widely used for volumetric sampling in the spawning survey. | |||||
