This article appears at mongabay.con, an environmental blog, written by Joanna Parkman. Read between the lines.- Investigating how trawling affects the prey and diet composition of two flatfish species, plaice (Pleuronectes platessa) and dab (Limanda limanda), Andrew Frederick Johnson, found that bottom trawling leaves plaice with reduced biomass. In other words, the fishing technique could be responsible for skinnier plaice. Read the rest here 17:22
Does this Species remain in this Area at all times or does the Species Migrate? Trawling churns up the Bottom exposing Sea Worms and other Forage. Still bottom could become stagnant or choked by Silt. Bottom Fishermen fishing in the Waters off of New England see different Species move in and out of the Mud and Sand Bottom. As the season changes the species change in type and abundance, One could see this as a migration pattern. As the Bottom is worked fish show up. A variety of forage is exposed after the Bottom is churned up and catches improve.
