This differences may be caused by several factors including the seasonal effect, habitat type, degree of stomach fullness, gonad maturity, sex, health, preservation techniques, food availability, and differences in the observed length ranges of the specimen caught (Tesch, 1971).…”

In this study, length-weight relationships (LWR) and Fulton's condition factor (K) values of totally 190 Common carp, Cyprinus carpio L., 1758 specimens, captured from Tercan Dam Lake between May 2017-October 2017, were examined. Sex composition was 41.58 % (n=79) female and 58.42 % (n=111) male. Female to male sex ratio of the population was found as 1:0.71. Fork length and weight values of overall, female and male specimens ranged from 11.2-55.5 cm/30.2-2860.5 g, 11.2-55.5 cm/30.2-2860.5 g and 12.7-47.5 cm/44.6-1846.9 g, respectively. K values varied between 1.204 and 4.008. The average value of its was calculated as 2.155±0.041 for females, 2.138±0.046 for males and 2.148±0.030 for overall. The LWR were determined W= 0.0646*FL 2.6613 for females, W=0.0389*FL 2.8103 for males and W=0.0528*FL 2.7202 for overall. The values of b was estimated as 2.66 (females); 2.81 (males); 2.72 in overall. According to b value of LWR, the growth of C.carpio was negatif allometric (b<3, P<0.005). No information currently exists on the LWR of C.carpio in the Tercan Dam Lake, Eastern Anatolia, Turkey. Therefore, this paper is an important contribution to the fisheries management applications.

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.

Age determination in common carp Cyprinus carpio: history, relative utility of ageing structures, precision and accuracy

The common carp Cyprinus carpio is one of the most widely-distributed freshwater fishes in the world. Due to its value for conservation and fisheries in several native/translocated areas of distribution and its detrimental effects on the aquatic ecosystem in most invasive areas, robust age-based population dynamics models are required for successful management of this species. The present study provides a global review of age determination in carp, including a historical account of ageing methods, an assessment of the relative utility of ageing structures, and an evaluation of precision and accuracy (i.e. validation) of age estimates. Historically, scales were by far the most widely-employed structure, followed by the operculum, otolith, dorsal spine, vertebra and fin ray. However, in countries where carp is categorised as 'high risk' of impact, use of alternative structures to the scale was predominant. Causal criteria analysis showed scales and opercula to provide inconsistent evidence for successful annulus identification/counting, whereas consistent evidence was found for otoliths, dorsal spines, vertebrae and (pectoral) fin rays. Precision was always above reference thresholds for scales, whereas for otoliths, dorsal spines and fin rays was in several cases below. Accuracy was addressed sporadically and mostly in high-risk countries. It is suggested that dorsal spines or pectoral fin rays should be used in lieu of scales as non-lethal ageing structures, and otoliths (or vertebrae, pending more research) otherwise, and that validation should always be attempted as part of the set-up of more appropriate ageing protocols and use of correct terminology.
