Length weight relationships of coleoid cephalopods from the eastern Mediterranean

open access: yesScientific Reports, 2022
AbstractLength-weight relationship (LWR) studies have been widely conducted for fish. They are important because they provide information about the growth of the fish, its general wellbeing, and fitness in a marine habitat. In comparison, relatively few LWR studies have been conducted on cephalopods.

Applying fuzzy logic to estimate the parameters of the length-weight relationship [PDF]

open access: yesBrazilian Journal of Biology, 2016
Abstract We evaluated three mathematical procedures to estimate the parameters of the relationship between weight and length for Cichla monoculus: least squares ordinary regression on log-transformed data, non-linear estimation using raw data and a mix of multivariate analysis and fuzzy logic. Our goal was to find an alternative approach that considers
