Effects of sediment properties and population density on Tubifex tubifex migration
底泥性质和分布密度对颤蚓迁移运动的影响

In this study,the effects of population density and sediment properties on the migration of Tubifex tubifex were investigated using a lab-scale simulation system. The results indicated that both the population density and the sediment properties had significant effects on the migration behavior of T. tubifex. The migration rate increased when population density increased since the increased population density resulted in a shortage of food. Thereafter,the migration rate decreased because the energy for migr...
