Enhancing Hediste diversicolor aquaculture production: Density and feeding rate as key variables for intensive production management

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 5, October 2025.
Abstract This study analyzes the effect of density on growth and feeding rate in Hediste diversicolor. In a first trial, specimens ranging in size from 10 to 500 mg were fed for 15 days at apparent satiety at eight stocking densities ranging from 500 to 16,000 individuals m−2. In a second trial, the effect of four manageable density levels ranging from
