Indian Major Carps (IMC) are bred from June-August in farmers’ ponds in Odisha. Mainly due to the late maturation of broods and traditionally believed that survival of early bred spawn is very poor. Mr. Batakrishna Sahoo (Batababu) of Sarkana village, Balianta Block under Khordha district, Odisha is a progressive fish farmer in the region and had produced about 20 crores of carp spawn during June-August 2012 by the traditional breeding management plan. Despite the fact that Batababu was producing seed for the last 20 years or so he had never thought of any possibility of early breeding of IMCs.
Shri Sahoo was advised to test CIFABROODTM for early maturation of carp in his pond. After a brief and routine preparation with lime and mahua oil cake, two ponds (0.3 ha. each) located side by side were stocked on 2nd February 2013 with the spent 250 numbers of catla, rohu, and mrigal (bred in 2012) at a density of 1000 kg/ha. The feeding trial started on 18th February 2013 and fishes were fed at 3% of body weight with CIFABROODTM in an experimental pond while farm-made feed was provided in the control pond. Shri Sahu noticed that within 30 days of rearing, Catla broods appeared healthier with more luster and glazy shining in an experimental pond than the control counterpart. Almost all the males, as well as the females of rohu and mrigal and a few catla, showed symptoms of phenotypic maturation within 30 days of feeding. Fishes were matured by the 1st week of April 2013 (in 48 days), although no water exchange or other management practices could be possible.
