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.

They are involved in economic activities and represent an important part of a country’s raw material potential. Many other organisms are also subject to rational use and protection. They can be associated with true resource species through interspecifi c relationships. The Caspian and Aral Seas are continental water bodies, giant saline lakes. Both categories of species are represented in the benthic and pelagic communities of the Caspian and Aral Seas and are involved in human economic activities.

KHALESI Sari Agricultural Sciences and Natural Resources University, Sari, Iran Received: 15.01.2012 Accepted: 14.08.2012 Published Online: 03.06.2013 Printed: 27.06.2013 Abstract: In this study, some serum factors in male and female Caspian kutum (Rutilus frisii kutum) broodstocks were investigated. 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.

Specimens were collected randomly from twelve stations in Mazandaran Province, the Caspian Sea Basin, between October 2009 and March 2010. Fork length, weight and length-weight relationship of samples were measured. One-way analysis of variance (ANOVA) showed that there is a significant difference for Pb and Cd content in liver and muscle (P<0.05). The highest level of bioaccumulation obtained for Pb in liver tissue (0.809 µg/g) from Fereidounkenar and the lowest level obtained for Cd in muscle tissue (0.038 µg/g) belongs to Koliver station. The results of linear regression analysis showed that, there were significant relationships between the heavy metal contents in both liver and muscle tissues and the fish weight (P<0.05). Comparison of heavy metal contents in both tissues revealed that the bioaccumulation of heavy metals in liver is higher than muscle.

In this study, 200 specimens (100 Females and 100 males) were collected using a gill and seine nets from March to May 2011 in Tajan River. Total length ranged from 37.1 to 54.7 cm and weights from 400 g to 1658.66 g. Age determination based on scale readings, showed that the population was composed of five age-groups. The highest and lowest age groups were 3++ (57.4%) and 1 age groups (0%) in females and 2+ (42.84%) and 6 + (0%) in males. Instantaneous growth of the fish at the 3++ - 4 age groups were very much lower than the younger age groups. Length-weight relationship showed positive allometric for males as W=0.0000005×L3.47 (R 2 =0.97) and a negative allometry model for female as W=0.00005 ×L2.73 (R 2 =0.93). Key words: Age Growth Rutilus frisii kutum Caspian Sea INTRODUCTION estuaries that discharged into southern part of Caspian Sea [4].

Abstract In this study, for the investigation of testicular structure and pattern of reproductive cycle in the male Caspian kutum, the sampling was achieved monthly from Jefrood coasts (Anzali, Guilan province, 37º 27´ N; 49º 33´ E) from October 2011 to late April 2012. After macroscopic observations and photographing position of sexual organ, the male gonad sections were removed and fixed in Bouin’s solution. After applying of various steps of histological method, 5 micron sections were prepared, then stained with hematoxylin– eosin and finally were examined by optical microscope equipped with a camera. The results showed that the developmental stages of kutum testis were divided into four stages. In Stage I (early maturing), the testes were thin and contained the spermatogonia and the primary spermatocyt. In stage II (late maturing), the primary and secondary spermatocytes were the most visible cells. In matured stage (stage III), all developmental stages of spermatogenesis were observed. In stage IV (ripe), the largest volume of theabdominal cavity occupied with lobules and they were full of spermatid and DNA carrier spermatozoa.

Most newly hatched fish and shrimp depend on live food as an important basic diet. Copepods are considered the nutritional benchmark diet for a wide range of marine fish larvae. However, Artemia and rotifers are often favored as starter feed, despite their inferior nutritional values in comparison to copepods. Therefore, Artemia, rotifers, and other live foods are commonly enriched with nutrients such as fatty acids, vitamins, minerals, and probiotics to imitate the copepod’s level of essential nutrients to improve rearing success for fish and crustacean larvae.
