A study on stocks of trap s fishes in Abumusa Island

This report is about coral-reefs around Abumosa lsland from January 1998 till February 1999 by trap and underwater visual census. Total species belonging to genus and family were idemtified and length-weight relationship were estimated for more frequent species. Small tooth emperor (Lethrinus microdon) was predominate from other species. Catch per unit of effort (CPUE) calculated for each trap (large, medium and small). Efforts were based on number of trap and day. Cupue of small and large traps was further in late summer compare other seasons. Results of catch analysis showed that no differ catch value (eatable, fishes, ornamental fishes and total catch) between small-medium and medium-large traps. Value catch wasn t significant difference between three depth (0-10, 10-20 and 20-30m) and four geographical side, too. But, catch value of ornamental fishes was significant difference between depths 0-10 and 20-30 meter

Evaluation of the effects of extraction of Kurdistan propolis on biochemical and microbiological parameters of rainbow trout (Oncorhynchus mykiss)

Spoilage of fish muscle results from changes brought about by biological reactions such as oxidation of lipids, reactions due to activities of the fish’s own enzymes and the metabolic activities of microorganisms. These activities lead to a short shelf life in fish and other seafood products. Propolis is a natural product derived from plant resins collected by honeybees. Propolis has been used in traditional medicine for centuries. It is known that propolis possesses anti- microbial, antioxidative, anti-ulcer and anti-tumor activities. At this study biochemical and microbiological parameters of rainbow trout (Oncorhynchus mykiss) treated to 10% concentration of alcoholic extraction of Kurdistan propolis for 24 days were determined. Analyses were carried out for mesophilic and psychrophilic bacteria counting as microbiological parameters and total volatile base nitrogen (TVBN), Thiobarbituric acid reactive species(TBARS), pH and acidity as biochemical parameters, for 0, 8, 16 and 24 days of storage at 4 ºC with vacuum packaging. The results presented that decreasing in microbiological parameters at control samples were more faster than treated samples and TVB-N,TBARS and acidity of control samples were higher than treated samples and pH of treated samples were higher than control samples after 24 days. The results suggest that 10% concentration of alcoholic extraction of Kurdistan propolis can enhance the shelf life of rainbow trout fillets during the refrigerated, vacuum packed preservation

Stock assessment of banana shrimp (Penaeus merguiensis) in coastal waters of Hormozgan Province

The survey was conducted during 2010 and 2011 on the banana prawn stocks in Sirik to Dargahan in Strait of Hormoz. Samples was taken by bottom trawl boats monthly. Growth in the prawns (male and female) was allometric and length of maturity in female was 31.7 (mm CL). Spawning season was occurred in winter from Jan to March. Growth parameters (K, L_∞) were 1.6 y^-1 and 49 (mm CL) for female and 1.9 y^-1 and 38 (mm CL) for male respectively. Instantaneus mortality rate (M, F and Z) calculated 2.6, 1 and 3.6 y^-1 for female and 3.1, 1.4 and 4.5 y^-1 for male respectively. Banana shrimp recruited at to fishing ground in Jun and Jul. Opening time for starting catch at 2010 was calculated at 28/09/2010 and total allowable catch was 1380 tones. At 2011 starting catch was calculated at 29.09.2011 and total allowable catch was 1480 tones. Time for end of catch season were stimated at 04.11.2010 and 21.11.2011 for each year. According to yield per recruit model, the best size of the banana prawn was 30 (mm CL) for female

Estimation of biomass and optimum of shrimp fishing season in Hormuzgan Province

This project was designed with for objective on estimation of Biomass and optimum time for catch season of P.merguinsis and M.affinis shrimps. This investigation was carried out monthly by swept area method in coastal waters of Hormozgan province. The optimum time for fishing season in Bandar Abbas to Sirik waters in 2004,2005 and 2006 respectively was about 25/9/2004, 24/9/2005 and 25/9/2006. Total allowable catch (T.A.C.) for P.merguiensis and M.affinis estimated in 2004 to 2006 were 600, 170 tonnes, 850, 550 tonnes and 650, 400 tonnes respectively. The densest catch was obtained for P.merguiensis (from 58/5 to 65/5 %) and the least catch for P.indicus (from 0/04 to 1/1 % ), respectievly

A survey on Movement and estimation of growth rate in banana shrimp (Penaeus merguiensis) released to the Persian Gulf and Oman sea waters (Hormuzgan province)

Banana shrimp (Penaeus merguiensis) is important shrimp species for stock enhancement in recent year in Hormozgan Tiab region. These crustacean spent post larve to juvenile cycle in mangrove creeks. Thus majore creek in this investigation are Tiab, Kolahi, Koleghan and Khamir (Laft). Maximum concentration of post larvaes in creek of Tiab, Kolahi and Koleghan are occur at April and in creek of Khamir is at May. Concentration of crustacean zoea and copepods that are diet of shrimp post larvaes, increase at this moment. Juveniles of Banana shrimp stay at those creek until June. At this time, juveniles reach to 14.6 mm (CL) and 2.9 g (TW). So optimum date to release is June for about 2.9 g of individuals. After June, concentration of juveniles decrease in creeks but increase in coastal waters. This variation in juvenile’s concentrations has negative correlation with temperature and salinity of water in creek. Amount of 187 fish stomachs (from 22 species) in the creeks were reviewed, about 56 (29.9%) of those stomachs were full or semi full conditions. Amount of 12 fish stomachs (6.4%) contain of shrimp as diet. The most important of these fish was Mangrove red snapper (Lutjanus argentimaculatus). About of 104789 juveniles of Banana shrimp (1.4g TW) in 2007 and 51401 juveniles (1.3g TW) in 2008 were tagged and released from 23 June to 16 July each year. Most of the shrimp (tagged and not tagged) released in Tiab creek. For recapture of tagged shrimp used 386 trawl survey and about 49.3 Km2 swepted by wooden boats. During the catch season (October to early November) about 10% of wooden boats and some shrimp processing companies were search daily for tagged shrimp, but no tagged shrimp were found

Prevalence and risk factors for HBV and HCV in prisoners in Iran: a national bio-behavioural surveillance survey in 2015

Objectives: To provide more accurate estimates of the prevalence of Hepatitis B (HBV) and Hepatitis C (HCV) and their contributing factors among prisoners in Iran. Methods: Cross-sectional study of 6200 Iranian prisoners in 2015. Data were collected through questionnaires and interviews. HBV infection and HCV exposure status of the participants was determined by HBsAg and HCV antibodies blood tests using enzyme-linked immunosorbent assay (ELISA). Data were analysed in STATA-12. Result: Prevalence of HCV exposure was 9.48 (95 CI: 8.73�10.27), and prevalence of HBV was 2.48 (95 CI: 2.07�2.89) in the general prison population. In multivariate analysis, the most important risk factor for HBV was a history of drug use in lifetime (adjusted odds ratio, AOR: 1.8, 95 CI: 1.17�3.02). The main risk factors for HCV exposure were a history of drug use in lifetime (AOR: 4.08, CI: 2.56�6.27), age over 30 (AOR: 2.68, CI: 2.01�3.56), and having tattoos (AOR = 1.67, CI: 1.35�2.07). Conclusion: Although vaccination is used to control HBV among prisoners, prevalence of HCV exposure is alarming in the prison population of Iran, especially among people who inject drugs. Eliminating viral hepatitis in Iran by 2030 requires a national commitment and rapid measures for targeting this high-risk group. Given the increased efficiency of HCV treatment in recent years, prisons provide an opportunity to access patients for treatment. © 2018 John Wiley & Sons Lt
