Abstract

Typically, growth can be defined as the change in size (length, weight) over time. The length- weight relationship (LWR) and annual condition factor of an economically important snow trout, Schizothorax niger, from Dal lake of Kashmir was studied and reported in this communication. A total of 120 specimens were collected with the help of traditional fishing gear during 2012-2013. The coefficient ‘b’ value of the LWR suggested allometric growth throughout the year except in April, July and September where the growth was isometric (b=3). A trend line graph was applied to compare condition of fish in different months as per the relationship, which indicated declining growth condition. The condition factor showed an overt variation with highest value during the breeding season. The result obtained in this study will be useful for fishery managers to impose adequate regulations for fishery and sustainable management.
