TL;DR: It was concluded that the use of traditional dry salting methods for Chalcalburnus tarichii had poor chemical and microbiologic qualities and especially salt, TVB-N and pH values which did not meat required standards, therefore the salted fish are not produced under hygienic and technologically satisfactory conditions.
Abstract: In this study, the chemical and microbial qualities of salted Chalcalburnus tarichii (PALLAS, 1811) caught from Van lake Basin were analysed. For this purpose 35 fish samples were collected from markets and homes and were studied. It was found that the samples contained total mesophilic aerobe bacteria, coliform group bacteria, Staphylococcus-Micrococcus, Enterococcus, psychrophile microorganisms, yeast and mold as 3.94, 3.20, 3.35, 3.38, 3.35, 3.02, and 3.24 log10 cfu/g respectively. At 20 o C and 37 o C incubation, halophile group microorganisms were found as 3.41 and 2.26 log10 cfu/g respectively and minimum and maximum values were <1.00 log10 cfu/g, and 4.08 log10 cfu/g. The value of microorganisms were considerably higher for 20 o C incubation (p<0.05) than for 37 o C incubation. Escherichia coli were present in the 3 % of samples and in the 100 % of samples contained Staphylococcus aureus. The mean values of the moisture, salt and TVB-N contents of the samples were 42.96%, 24.63%, and 55.40 mg (as mg/100g), respectively. The salt contents of dry matter and pH were found as 43.74% and 5.79, respectively. It was concluded that the use of traditional dry salting methods for Chalcalburnus tarichii had poor chemical and microbiologic qualities and especially salt, TVB-N and pH values which did not meat required standards. Therefore the salted fish are not produced under hygienic and technologically satisfactory conditions. The more and deliberate studies are required to solve quality problems of salted fish.

TL;DR: The study confirms the opinion of Holcik & Jedlicka (1994) who regard subspecies designation in many cyprinid fishes as unwarranted and indicates that both these nominal subspecies, and a third subspecies C. chalcoides latissimus, are probably not distinct from the type subspecies.
Abstract: The shah mahi, Chalcalburnus chalcoides, has four nominal subspecies in the southern Caspian Sea and its basin. The systematics of this species was examined using principal components analysis on 21 morphometrjc and 12 meristic characters. C. chalcoides iranicus was found to be indistinguishable from C. chalcoides longissimus, which has priority. Analyses also indicate that both these nominal subspecies, and a third subspecies C. chalcoides latissimus, are probably not distinct from the type subspecies. The study confirms the opinion of Holcik & Jedlicka (1994) who regard subspecies designation in many cyprinid fishes as unwarranted.

TL;DR: In this paper, the optimal pH and temperature of AChE were determined for the Lake Van fish using affinity chromatography, and the results showed that the optimum pH and the optimum temperature were 8.0 and 25°C, respectively.
Abstract: In this study, acetylcholinesterase (AChE; EC 3.1.1.7) was purified from plasma and erythrocytes in the Lake Van fish (Chalcalburnus tarichii P.1811) by affinity chromatography. Enzymatic activity was spectrophotometrically measured according to Ellman’s method, at 412 nm. Then, the optimal pH and temperature of the enzyme was determined. According to the results, the optimal pH and the optimum temperature were 8.0 and 25°C, respectively. In order to control the purification of the enzyme, sodium dodecylsulfate-polyacrylamide gel electrophoresis (SDS-PAGE) was done. SDS-PAGE showed a single band for enzyme. The purification rates for plasma AChE and erythrocyte AChE are 3251.6 and 8500, respectively.

TL;DR: The age, growth, and reproduction of Chalcalburnus belvica from Lake Mikri Prespa (NW Greece) were analyzed using scale readings and size frequency histograms, revealing a prolonged spawning period from April to August, with multiple egg sheddings.
Abstract: Age, growth, and reproduction of Chalcalburnus belvica from Lake Mikri Prespa (NW Greece) were analyzed using scale readings and size frequency histograms. Males aged 1+ and 2+ were dominant in the catches; high mortality at ages 3+ and 4+ precluded their occurrence at older ages. Females always had a higher mean observed length than males of the same age and grew to age 8+. The weight-length relationship was allometric with b coefficients greater than 3 for both sexes. C. belvica matures genitally at age 1+ in both sexes. Reproduction occurs in the lake, in contrast to other fish species of the same genus which migrate to the rivers to reproduce. The reproduction pattern reveals a prolonged spawning period from April to August, with multiple egg sheddings. Von Bertalanffy's growth equation yields a rather low growth rate (k = 0.230) and a relatively high maximum fork length (L∞ = 250 mm).

TL;DR: The results showed that Chalcalburnus chalcoides aralensis grew well in water containing 5 g/L salinity, 23.65 mmol/L alkalinity and pH 9.2.
Abstract: Some biological features of wild and domesticated species of Chalcalburnus chalcoides aralensis were discussed, which were its diagnostic features, living environmental habits, feeding pattern and propagation characteristics. Its abilities in resisting salinity, bicarbonate alkalinity and pH were especially studied. The results showed that Chalcalburnus chalcoides aralensis grew well in water containing 5 g/L salinity, 23.65 mmol/L alkalinity and pH 9.2. It was concluded that Chalcalburnus chalcoides aralensis fits to live in brakishwater.
