Heterotisniloticus was stocked in the Niger Delta University Teaching and Research farm in September 2015 in an eathern pond of 100m³. This study was carried out to understand its well-being in this facility. The length-weight relationship and condition factor was investigated to determine its growth pattern in captivity. A total of 60 fish samples were used in the study comprising 28 males and 32 females. The length-weight measurements were assessed using standard methods. The total length for male ranged from 33-77cm with a mean length of 52.25±1.9cm and weight ranging from 200-4300g with a mean weight of 1221.429±149.4g. The total length of female ranged from 50-73cm with a mean length of 58.86±1.3cm and weight ranging from 1100-4100g with a mean weight of 1631.25±41.8g. The total length of combined sexes ranged from 33-77cm with a mean length of 55.77±1.2cm and weight ranging from 200-4300g with a mean weight of 1440±101.9g. The males had an intercept (a) value of -1.7441, a slope (b) of 2.785 and a correlation coefficient of (r) of 0.943133. Females had an intercept (a) value of -1.6004, slope (b) of 2.7072 and a correlation coefficient (r) of 0.897441. The combined sexes had an intercept (a) value of -1.7309, slope (b) of 2.7794 and a correlation coefficient (r) of 0.937763. The condition factor (k) for males, females and combined sexes ranged from 1.02-3.01, 1.38-2.56 and 1.02-3.01 respectively with an average of 1.88 for all fish samples. The results indicate a negative allometric (b<3) growth pattern. This study provides the first basic information on length weight relationship and condition factor of Heterotisniloticus in captivity from the various ponds and reservoir in the Niger Delta University Teaching and Research Farm.
