“…The same trends were exhibited by major carps in corn gluten and soy bean meal treated raceways. These co-ordinations of ecological factors for the growth of experimental carps confirm the consequences of Moata et al (2005). An isometric type of growth of Indian major carps was also evident in extensive system, but condition index (K) of all experimental carps varies notably among treatments (Bhakta et al, 2019).…”

The present findings provide information regarding the length-weight relationships (LWRs) of Indian major carps viz Cattla cattla, Labeo rohita and Cirhinus mrigala in an intensive polyculture system. Much work has been done in Pakistan with respect to fish LWRs, much of such work has been ignored. Carps were fed with twelve different formulated diets containing four different sources of protein i.e. fish meal (FM), all parts chicken meal (APCM), corn gluten (CGM) and soybean meal (SBM). Each type of protein is used at inclusion level of 25, 35 and 45% into the formulated diets to evaluate the minimum requirement of that ingredient for optimal growth of in-hand species. The values of slope “b” ranged from 2.20 to 4.90 for these species of carps which showed a strong healthy relationship among variables (level of protein and months).

“…Te negative allometric growth of C. carpio in the Lake Arekit showed that the fsh were not developing properly, presumably as a result of the inappropriate environmental conditions as well as overfishing. However, other studies [25,28,31] indicated positive allometric growth patterns (Table 5). Te variations in the growth pattern of the same species in diferent geographical localities may be due to various factors, such as the number and size of specimens examined, stomach fullness, sex 6).…”

Cyprinus carpio is a widely distributed and commercially important fish species in Ethiopia. Effective management is essential to sustain fisheries and provide benefits to local communities. This study aims to estimate the growth, mortality, and exploitation rate of C. carpio using length-frequency data. A total of 194 C. carpio specimens (117 females and 77 males) were collected between June 2022 and May 2023. The population parameters were determined using FISAT (ELEFAN I) software. The Von Bertalanffy growth function estimations were L∞ = 51.45 cm total length, K = 1.1 year−1; t0 = −0.124 year, and growth performance index (Φ′) = 3.464. The total mortality rate (Z), natural mortality rate (M), and fishing mortality rate (F) were 2.55 year−1, 1.58 year−1, and 0.97 year−1, respectively. The estimated potential longevity (tmax) and average age at which C. carpio attains length at the optimum cohort biomass or yield per recruit (Lopt = 34.79) in Lake Arekit were calculated as 2.60 years and 1.29 years, respectively. The Z/K ratio (2.32), exploitation rate (E = F/Z = 0.38), and highest permissible yield per recruit for C. carpio (Emax = 0.421) suggest enhancing fishery production by increasing the exploitation rate of the underexploited C. carpio in Lake Arekit. The results of this study provide information on the stock of C. carpio, which can be used to guide management efforts. The fish catch in Lake Arkeit is currently far lower than it could be. Therefore, the fish harvest should be boosted through the use of permitted nets, the establishment of groups of fishermen who can catch fish effectively, and the linking of the benefits of fish farming’s supply chain to the potential of fisheries.
