Catch per unit area of batoid fishes in the northern Oman Sea

We report on results of a trawl survey to assess the abundance of Batoid fish resources in the Oman Sea. The catch per unit area CPUA as the main index was estimated. The objectives of this study were to determine the catch composition and distribution pattern of Batoid fishes in the study area and in different depth strata of the Oman Sea. A total of 82 stations were randomly selected 2012. The comparison between 5 strata indicated that, the highest CPUA was found for strata E, Beris to Gowatr (2712.56 kg / nm^2) and C, Gordim to Konarak (2079.17 kg / nm^2) and the lowest one was found in stratum B, Darak to Tang (27.11 kg / nm^2). Also the comparison of mean CPUA in different depth-layers revealed that the mean CPUA has a descending trend with increasing of depth, in which the CPUA values in depth layer 10-20 m were 101.38 times more than depth layer 50-100m

Effect of short term starvation and re-feeding on some growth, feeding factors and body composition Blue Streak Hap (Labidochromis caeruleus)

In this study, the effects of starvation and re-feeding on growth performance and body biochemical composition of Blue Streak Hap (Labidochromis caeruleus) were conducted at autumn 2014. A total of 450 fish were assigned to 5 treatments with 3 replicates. 15 tanks were prepared with a volume of approximately 120 liters and trial period was considered 48 days in experimental conditions. Treatments included 0, 2, 4, 8 and 16 days of starvation. Fish after two weeks of acclimatization to the laboratory conditions, were examined based on the pattern of starvation and re-feeding. The results of the growth performance and biochemical composition showed that, treatments 2 and 4 days of starvation, compared to the control group were able to compensatory growth in the period of re-feeding and did not show a significant difference in any of the treatments (P> 0/05). But treatments 8 and 16 days of starvation not be able to compensate growth and expenditure of excess metabolic energy due to starvation period, and had significant differences in the growth and nutritional factors as well as significant differences in the lipid and protein level compared to the control group

Investigation of physicochemical factors, chl-a and primary production in Mahshahr Creeks (Northwest Persian Gulf)

The study on physicochemical factors and primary production of the aquatic ecosystems is important to know the characteristics of the environment and capacity of recharge. Mahshahr Creeks are the most important creeks in the Northwest Persian Gulf, Iran. In this study, variations in physicochemical factors, chl-a, and primary production in creeks of Mahshahr, Zangi, and Moussa were evaluated for 2 months of every season of 2014. The following variables were analyzed: nitrate, phosphate, nitrite, silicate, temperature, salinity, DO, pH, conductivity, turbidity, light, chl-a, primary production and phytoplankton abundance. The maximum amount of chl-a (1.6 mg m^3) was observed in Moussa Creek in April while the minimum amount (0.1 mg m ^-3) was seen in Moussa in July. The highest (1.19 gc m^-2 day^-1) and lowest (0.1gc m^-2 day^-1) amount of primary production were observed at the entrance of Moussa Creek in April and in Zangi Creek in November, respectively. The maximum and minimum abundance of phytoplankton was observed in April and October, respectively in all study areas. The results of correlation test between the studied factors revealed that primary production has a significant relationship with nitrite, chl-a, phytoplankton abundance and light. Primary production in these creeks is relatively high in April and is attributed to the uptake of nutrients including nitrate and phosphate from shallow waters entering these creeks, sufficient light and suitable temperature, but in other months the production is low

Effect of crocin on inhibitory avoidance memory, balance and explorative behaviours following cisplatin administration in rat

Background: A lot of studies indicate that cancer chemotherapy results in memory and motor impairment immediately following therapy. On the other side, crocin as the chemical constituent isolated from the Saffron is effective on memory and motor impairement. In this study, the effect of crocin on memory and motor impairment induced by cisplatin injection was studied in adult male rats. Materials and Methods: In this study, male Wistar rats (n=50) were divided into 5 groups: Control, Sham, Cisplatin (2 mg/kg/week for 21 days), Crocin (30 mg/kg for 21 days) and Cisplatin+Crocin. Sham group was administrated with Saline. Then, inhibitory avoidance memory, balance and exploratory behaviors were assessed by shuttle box, rotarod and open field apparatus, respectively. Results: Crocin improved memory impairment induced by cisplatin (P<0.01). Cisplatin also impaired balance in rotarod test. Rearing frequency and total distance traveled in open field test were significantly decreased (P<0.001 and P<0.05, respectively) compared to Control group. Conclusion: We conclude that crocin injection following the use of anticancer drugs (e.g. cisplatin) might have a protective effect against the cisplatin-induced impairement in cognitive function, balance and explorative behavior
