Équation de production: adaptation du modèle de Ricker à un stock de poissons exploité par différents engins | Yield equation: adaptation of Ricker model to a fish stock exploited with different gears
1975
Le Guen, J.C. | Pianet, R.
The authors have developed the method used by Pianet and Le Hir (Doc.Sci.Cent. ORSTOM Pointe-Noire, 17, 1971) for the study of albacore (Thunnus albacares) in the Pointe-Noire region. The method is based on the fact that the ratio between unit of effort and number of fish for two fishing gears is equal to the ratio of their catchability coefficients.
