Ferdous Ahamed, Zoarder Faruque Ahmed, Md. Yeamin Hossain, and Jun Ohtomi (2012) The pool barb Puntius sophore (Hamilton
1822), is a freshwater to brackish-water cyprinid widely distributed in
Asia, including Bangladesh, Pakistan, India, Nepal, Myanmar, Bhutan,
Afghanistan, and China. The growth pattern and longevity of P. sophore
were studied in the Old Brahmaputra River, Bangladesh, using time
series of the length-frequency distributions through multi-model
inferences in Jan.-Dec. 2009. Both males and females were
recruited in May, with respective modal sizes of 32 and 36 mm standard
length. Growth was best described by the von Bertalanffy equation
as Lt ≡ 63.90[1-exp{-0.156 (t + 3.418)}] for males and Lt ≡ 74.17[1-exp{-0.141 (t
+ 3.839)}] for females. Females grew faster and reached a larger
size at the same age than males. The longevity of this species
was estimated to be ~15 months for both sexes. The relationship
between the standard length and body weight indicated isometric growth
in both sexes.
Key words: Cyprinidae, Growth, Length-frequency, Multi-model, Puntius sophore.
