Synthetic length frequency data III

Description

Synthetic length frequency data from Sparre & Venema (1998). Can be used for the estimation of the instantaneous total mortality rate (Z) by means of Z_BevertonHolt.

Usage

data(synLFQ3)

Format

A list consisting of:

• midLengths: midpoints of the length classes,

• Linf: infinite length for investigated species in cm [cm],

• K: growth coefficent for investigated species per year [1/year],

• t0: theoretical time zero, at which individuals of this species hatch,

• catch: a vector with catches.
