| 内容記述 | Short term variations in the number of collected eggs of the Japanese sardine, Sardinops melanostictus, were investigated in the adjoining area of Nagasaki Harbor. Sardine eggs were collected at the nine stations by plankton net at intervals of one to nine days. At two stations, samplings were carried out every other hour during the nighttime. The total number of sardine eggs collected at the nine stations varied from 2,259 to 4,655/haul in the three days in 1988. Variation in the number of eggs sampled over seven days in 1989 was approximately 5.1 times from a minimum of 1,919 to a maximum of 9,781 eggs/100m³. The number of sardine eggs collected every other hour varied 2.3 times from 148 to 344/100m³ at one station and 6.6 times from 11 to 72/100m³ at the other station. The maximum variation of sardine egg numbers collected at the nine stations was 11.7~20.4 times in the three days in 1988 and 5.4~33.8 times in the seven days in 1989. This result indicates that the number of sardine eggs collected by plankton net changes considerably during short time periods and between adjacent stations, and that the total egg production calculated from spawning survey data may include wide variations. | |||||
