“…Interestingly, a negative allometric growth pattern with a b value of 2.56 was observed in S. seenghala from the Sutlej River, Punjab (Kaur et al 2022). The b value for C. carpio was similar to that in a study conducted by Rashid et al (2018), in which this species exhibited a negative allometric growth pattern identical to that in the present study. In the present study, the value of K was equal to one, which indicated the optimum well-being of the fishes inhabiting the Sutlej River, India.…”

Waterbodies are polluted by human activities or the increasing intensity of these activities, and this affects fish populations. The quality of the water fish inhabit directly impacts their growth and overall health. Length-weight relationships (LWRs) and relative condition factors (Kn) were estimated for three freshwater fish species from the Sutlej River of India from October 2020 to May 2022. A total of 232 fish specimens were caught with cast and gill nets in Gobindsagar Reservoir, Himachal Pradesh and Ropar Wetland, Punjab. Total length was strongly correlated with all the morphological characters (p < 0.001). The growth coefficients calculated (b) for Bangana dero, Cyprinus carpio, and Sperata seenghala were 2.858, 2.506, and 2.555, respectively, and indicated negative allometric growth. The correlation coefficients (r) indicated strong linear relationships between the weights and lengths of all three fish species. The outcomes of this study will help fisheries researchers, environmentalists, and scientists to develop future monitoring and conservation strategies for these fish species.

“…Alp and Balik (2000) recorded negative allometric growth (b= 2.8740) for common carp in Gölhisar Lake, and Tarkan et al (2006) recorded b of 2.8300 for common carp in Lake İznik. Similar results have been found for the common carp cultivated in different ponds environment (Kadhar et al, 2014) and for common carp from Taqtaq Region of the lower Zab River-Northern Iraq (Rashid et al, 2018). Positive allometric growths (b=3.319) were recorded for some populations of common carp in Almus Dam Lake and also for Ömerli Reservoir (b=3.140) (Karataş et al, 2007;Vilizzi et al, 2013).…”

The experiment was conducted at Agricultural Research Station- Aquaculture Unit- Agriculture College- Basrah University in six earthen ponds (600 m3). The stady inclouding of alien organizms effect on growth of common carp Cyprinus carpio. Using an agricultural shadow as a filtering fabric was put in inlets pipes (T1), while T2 without filters. Fishes was daily feeding by a commercial sinking pellets manufactured by Agricultural Consultant Office belonging to Agriculture College, With a ratio of 3% from fishes weight. Total length and weight of fishes were measured at the beginning and at the end of the experiment. The weight of subsamples for fishes were taken periodically and daily feed changed after each weighing. At the end of the experiment the alien organism in all ponds were collected, classified and weighed individualy except shrimp. Results of current experiment revealed that there were significant differences (P≤0.0.5) in final weigh, wight increment, daily growth rate and feed conversion rate between fishes reared in ponds with and without filter. These differences may be related to differences in numbers and weighs of alien organisms in these ponds (97 individuals of six fish species in ponds without filter comparing with two individuals of one fish species in ponds with filter, and also 16314 g of shrimp in ponds without filter comparing with 440 g in ponds with filter). From the results of the current experiment, it can be concluded that culturist must used filters in inlet pipes of their ponds to prevent or reduced the entering of alien organizms to these ponds.
