Description Fishes are unique among vertebrates, especially when their growth patterns are taken into
account. Baring very few exceptions, fishes show an indeterminate type of growth, implying
that they show continued growth throughout the life, invariably with rate of growth declining
with age (Mommsen, 2001). The growth among fishes, like other organism are affected by
several factors like abundance of food, ambient physical environment, internal biological
cycles (e.g. reproductive cycles), etc. Growth monitoring is a key discipline in fisheries, be it
capture or culture sector. Growth can be monitored either in terms of change in length or
weight. Weight-length relationship enables the inter-conversion of these two measures of
growth. Establishing weight-length relationships though a routine exercise in fisheries, still
the relationships are available for a limited number of species, considering the enormous α-
diversity among fishes (Kulbicki et al. 2005; Froese, 2006).
