Age Structure of Roughhead Grenadier (Macrourus berglax) in the Northwest Atlantic, 1985

Keys for converting roughhead grenadier (Macrourus berglax) length distributions into age were made using samples collected in a bottom trawl survey in NAFO Div. 0B, 2G, 2H and 3K in 1985 at 610–1 240 m depths. Ageing was done on scales using polarized transmitted light. Age structure of catches fro...

Linear growth was expressed by exponential functions and the von Bertalanffy formula, and weight by exponential functions and the Gompertz formula.
