Stage Dependent Vertical Distribution of Haddock ( Melanogrammus aeglefinus ) Eggs in a Stratified Water Column: Observations and Model
The depth distribution of four development stages of haddock (Melanogrammus aeglefinus) eggs was measured during May 1984 in a continuously stratified water column over Browns Bank. The egg profile varied with development. Early stage eggs were most concentrated near the sea surface whereas late sta...
