An Age- and Temperature-Mediated Growth Model for Cod (Gadus morhua) and Haddock (Melanogrammus aeglefinus) Larvae in the Gulf of Maine

摘要: While field studies of larval fish growth require an easily parameterized model, simple relationships between size and age are seldom applicable to other populations and/or environments. The model presented here attempts bridge the gap age–length regressions more sophisticated experiment-based models by incorporating a temperature term as function absolute rate. Growth is assumed be logistic, with influencing rate parabolically on daily basis. integrated form provides estimate length-at-age larva. When fitted variety independent cod (Gadus morhua) haddock (Melanogrammus aeglefinus) data sets collected in Gulf Maine, performed minimal bias despite absence food availability term. Larval were generated through validated otolith microstructure examinations, although resolution limits light microscopy introduced small degree (2–3 d) into estimat...
