Methods for Obtaining Growth Parameters from Length-at-Age Data. The method most commonly used for estimating the parameters L∞ and K of the VBGF is the “Ford-Walford Plot” which essentially consists of a rewritten version of the VBGF of the form. Lt+1 = a + bLt.

WebMar 1, 1997 · Since the Ford-Walford plot method used only the growth data with equal time intervals, the maximum likeli- hood required high research experience and, the iterative method described above can be used in more practical situations. References Faben, A.J1965. Properties and fitting of the von Bertalanffy growth curve. WebAbstract: Fish lengths have been measured in many different ways The differences arise from choosing different reference points near the anterior end and near the posterior end of the fish, and from using different methods of making the measurement Methods of making the measurement include using calipers; using a tape held along the curve of the body; … Webaccording to the predictions of monthly Ford-Walford plots, until December 1983, was calculated for each site. When the line described by the equation Lt+ , = Lt (i.e. no growth) is superimposed on each Ford-Walford plot, the intercept of the 2 lines indicates the predicted maximum length of a limpet growing at that site (Loo) (Balaparames- east finchley to leicester square
