Description The growth of hatchery produced Portunus pelagicus crabs was monitored under laboratory
conditions by recording growth at each moult from the 1st crab instar onwards. Male and female
crabs attained sexual maturity by their 12th and 14th moult, respectively. The experiment lasted for
455 days when the last crab died. This paper describes the growth of male and female crabs in each
moulting stage, with details of their carapace width and length, chelar length and height, abdominal
width and length, and total weight. Moulting frequency, secondary sexual characteristics, and moult
increments were also monitored. VBGF (Von Bertalanffy Growth Formula) fit was obtained using the
methods of Gulland & Holt (1959), Fabens (1965), and Munro (1982). The L∞ values calculated
by the different methods ranged between 204.1 and 219.8 mm in males, and between 188.6 and
211.8 mm in females.
