Growth Parameters, Mortality Rates, Yield Per Recruit, Biomass, and MSY Iranian Journal of Fisheries Sciences 11(1) 48-62 2012 Growth parameters, mortality rates, yield per recruit, biomass, and MSY of Rutilus frisii kutum, using length frequency analysis in the Southern parts of the Caspian Sea Gheshlaghi P.1; Vahabnezhad A.2; Taghavi Motlagh S. A.2 Received: March 2011 Accepted: July 2011 Abstract The growth and mortality coefficient of Rutilus frisii kutum, were estimated using length frequency data collected in southern waters of the Caspian Sea during October 2008 to April 2009. The following population parameters were evaluated: length-weight relationship, W = 3.258 0.004L , (r= 0.976); Von Bertalanffy growth constants, W∞ (g) = 4192.3, L∞ (cm) = 70.45, K = 0.2, per year; t0 = −0.75; total mortality and its components, Z = 0.92, M = 0.36, F = 0.56 per year. The exploitation rate (E) was estimated about 0.6. The current yield per- recruit was estimated to be 279.15 g, which was only 1.2% less than Maximum yield per recruitment that was estimated as YPRmax = 287.535, it means if fishing mortality increases from 0.56 per year to 0.7 per year, the yield will raise by only 1.2%. The current YPR and maximum YPR, which were gained at fishing mortality of 0.7, showed that most kutum individuals are caught before reaching the length of maturity. Therefore, to get a maximum YPR, it is necessary to increase fishing effort, even higher than the optimum level.

  • Histopathological Effects and Toxicity of Atrazine Herbicide in Caspian Kutum, Rutilus Frisii Kutum, Fry
    Iranian Journal of Fisheries Sciences 13(3) 702- 718 2014 Histopathological effects and toxicity of atrazine herbicide in Caspian Kutum, Rutilus frisii kutum, fry Khoshnood Z. 1*; Jamili Sh. 1; Khodabandeh S.2; Mashinchian Moradi A.1; Motallebi Moghanjoghi A.A.3 Received: June 2012 Accepted: May 2014 Abstract This study aimed to investigate the toxic effects of atrazine herbicide on the fry of Caspian Kutum (Rutilus frisii kutum, Kamensky, 1901). First the 96-h LC50 of the fry were exposed to atrazine at the concentration of 24.95 ppm was determined. Then the toxicity of this herbicide on Caspian kutum fry exposed to the concentration of 12.47ppm (1/2 LC50), for four days was measured and compared with a control group. Comparison of the length, weight and condition factor showed no significant differences between atrazine exposed and control group. The concentration of Na+, K+, Ca2+, Mg2+ and Cl- in the whole body of fry in control and atrazine exposure groups were as the following order: Ca2+>K+> Na +> Cl- >Mg2+ and Ca2+>Na+>K+>Mg2+>Cl-, respectively. Results showed that the concentration of all these ions were higher in atrazine exposure group than control group, except for Cl-, and the only significant differences was found in Na+ concentration. Major histopathological effects of atrazine on the gills were hyperplasia and thickening of the filaments, separation of the pavement cells of the lamellae epithelium from the pillar cells and swelling of the epithelial cells. Results of the present study showed that atrazine could affect the ion composition of the body, and caused major damages in gill epithelium even at sublethal concentration and acute exposure, but had no effects on the growth parameters.

Accepted 28 December, 2011 Experiments were conducted to study the downstream migratory behavior and effects of weight on osmoregulation ability of hatchery-reared Rutilus frisii kutum fingerlings during adaptation to the seawater. Accordingly, blood osmotic pressure regulation ability in kutum fingerlings with weights of 1, 3, 5 and 7 g in three different salinities, 13 ppt (Caspian Sea salinity), 7 ppt (estuarine area) and 0.3 ppt (freshwater) were assessed. The blood samples were collected before being transferred as control (freshwater) and after exposure to the sea and estuarine water in a period of up to 336 h by a pooling method. The results indicate that only 3, 5 and 7 g kutum are able to adapt to salinity of 7 and 13 ppt since they maintained the osmolarity.

The estimated values were compared between male and female fish of various age groups. A total of 80 mature fish (40 males and 40 females) were randomly caught from the Shirood and Tajen rivers (southern Caspian Sea) during spawning season. Blood samples were then taken from the caudal peduncles and the serum biochemical parameters were measured according to common laboratory methods. Cholesterol levels showed significant differences (P < 0.05) between male and female broodstocks from the Tajen River, as well as between male and female kutum of the Tajen and Shirood rivers. Comparison of the estimated serum factors with the fish ages revealed no significant changes (P > 0.05). A high correlation was found between total protein and weight in fish from both rivers based on Pearson’s correlation. This study suggests that male and female variations in blood factors should be taken into account when these parameters are used to assess sex, age, and spawning sites.

  • Effects of Different Starter Diets on Growth Indices of Caspian Kutum, Rutilus Frisii Kutum Larvae
    Iranian Journal of Fisheries Sciences 11(1) 28-36 2012 Effects of different starter diets on growth indices of Caspian Kutum, Rutilus frisii kutum larvae Falahatkar B.*; Mohammadi H.; Noveirian H. Received: December 2010 Accepted: April 2011 Abstract Six different diets including two rainbow trout starters, Gammarus dry powder, shrimp dry powder, egg yolk dry powder and newly hatched Artemia were used in feeding of Caspian Kutum larvae. During a 4-week trial, larvae with a mean weight of 17.5 ± 4.7 mg were fed with three replicates and growth parameters were measured at the end of the experiment. Thirty fish in each experimental unit with 3 L volume were fed 6 times daily according to their satiation. Results showed that there were significant differences in the final weight, final length, body weight increase, voluntary feed intake and specific growth rate for weight and length among the treatments (P<0.05), but not in the condition factor (P>0.05). The best performance was observed in fish fed Artemia nauplii. The survival rate was significantly different among the treatment (P<0.05) which the highest (75.6 ± 3.8%) and lowest (22.2 ± 11.7%) were observed in fish fed Artemia nauplii and Coppens, respectively. According to obtained results, it appears that except Artemia, the most suitable and inexpensive diet is egg yolk powder, which can results in high growth performance and survival rates. The results of this study suggested that using dry non-live diets with good composition could be replaced with Artemia that had suitable growth and survival rate in Caspian Kutum during larval.

Box 1144, Sowmeh Sara, Guilan, Iran Abstract: The main aim of this study was to obtain a basic knowledge of the hematology of mature Kutum in migrating time and comparison hematological parameters between male and female specimens. Lymphocytes, monocytes, neutrophils, eosinophils and myelocytes, were distinguished. Hematological indices included Red Blood Corpuscles (RBCs), White Blood Corpuscles (WBCs), Hematocrit (HCT), Hemoglobin (Hb), Mean Corpuscular Volume (MCV), Mean Corpuscular Hemoglobin (MCH), Mean Corpuscular Hemoglobin Concentration (MCHC) and leukocyte differential count were measured in one blood sample from 30 Rutilus frisii kutum captured in south of the Caspian Sea, in river-mouth of the Tajan River, north of Iran. Eighteen and twelve of the specimens were male and female, respectively. The mean of counted red blood cells was 1.81±0.22×106 per mm3 blood. The mean of counted white blood cell was 16.07±2.38×103 per mm3. The average of hematocrit, 53.09±4.75 percent was calculated. The average of hemoglobin values was 16.66±2.31. Blood indices; the average of MCV 294.46±65.85 FL, the average of MCH 92.38±11.82 Pg and the average of MCHC 36.40±3.63 percent, were calculated.

Accepted 28 December, 2011 Experiments were conducted to study the downstream migratory behavior and effects of weight on osmoregulation ability of hatchery-reared Rutilus frisii kutum fingerlings during adaptation to the seawater. Accordingly, blood osmotic pressure regulation ability in kutum fingerlings with weights of 1, 3, 5 and 7 g in three different salinities, 13 ppt (Caspian Sea salinity), 7 ppt (estuarine area) and 0.3 ppt (freshwater) were assessed. The blood samples were collected before being transferred as control (freshwater) and after exposure to the sea and estuarine water in a period of up to 336 h by a pooling method. The results indicate that only 3, 5 and 7 g kutum are able to adapt to salinity of 7 and 13 ppt since they maintained the osmolarity.
