Nine species exhibited positive allometric growth, 10 species were negative allometric growth, 3 species had isometric growth and 1 species was Gompertz form of growth. The length-weight relationships for some species from the Merbok estuary are hereby publish for the first time, and most of the fish specimens were juveniles.
