Abstract
Effects of bait digging on distribution and population recovery of A. marina, Hydrobia ulvae and Macoma balthica were investigated on trial plots at Blackness, Forth estuary (Scotland [UK]). A. marina rapidly recolonized the basins created by digging, but had reduced populations on the dug mounds. Its populations were dislocated for over 3 mo. after digging. H. ulvae and M. balthica showed enhanced populations on the mounds for up to 2 wk, but were otherwise unaffected by digging. Factors influencing the mode of population recovery are discussed; enhanced basin populations of recolonizing A. marina are due substantially to above-surface migration of worms into areas with increased levels of organic matter.This publication has 0 references indexed in Scilit:
