    Description: More than the COVID-19 pandemic itself, the lockdowns to prevent its spread have harder hit Nigeria’s unorganized small-scale fishers. The COVID-19 pandemic has fundamentally struck all facets of life in affected countries and the small-scale fisheries (SSF) of Nigeria are no exception. The pandemic has hit the country’s small fishers both directly and indirectly. Small operators are the bulk of Nigeria’s fisheries sector. They account for 70 per cent of the domestic fish production, and sustain the livelihoods of millions of people in one way or another; the dependence on local fish species for economic and food security is evidently large. SSF provides an accessible, cheap and rich source of protein and essential micronutrients to the rural population. Their impact on social, economic and cultural spheres is immense.

    Description: This study was done to investigate the macroscopic and microscopic structure of the ovary of Acanthopagrus latus and their changes during sexual maturation cycle from October 2011 to may 2011. 80 A. latus from Mussa Greek (North West of Persian Gulf) were captured and transferred to the laboratory. After biometry, gonads were removed, were weighted and fixed in Bouin's Fluid. Samples were dehydrated, clarified, embedded and sections were prepared. After staining with H&E these slides were studied under light microscopy. Gonadosomatic indices, macroscopic and microscopic changes in the ovary during different months were recorded. The minimum value of GSI were measured in May, (0.31 ± 0.01) while its maximum was seen in March (9.9 ± 3.1). Cyclic changes in ovarian maturity were divided into six stages, including immature, premature, mature, ripe, spawning and resting. A. latus had asynchronous spawning that was occurred from February up to March.

    Description: The effects of inulin were studied on the growth indices, intestinal morphology as well as fatty acid profile of the Pacific white shrimp, Litopenaeus vannamei with average weight 3.21±0.03 g for 5 weeks. The experiment was carried in triplicate, was conducted in circular PVC tanks of 300 L capacity with 25 shrimp per tank at the Aquaculture Center (Delvar, Bushehr province). Inulin was added to the diets at a 2 levels (0 and 2 percent). The shrimp were fed the experimental diets to visual satiety five times a day at 08:00, 12:00, 16:00, 20:00 and 24:00 h. No significant differences in growth performances (such as survival, feed conversion ratio (FCR), specific growth rate (SGR), Protein efficiency ratio (PER)) was observed, however, Dietary inulin brought about significantly improved 20:3n3 fatty acid content between the two treatments (P〉0.05). Intestine epithelium cells height in the abdominal sections significantly (P〈 0.05) were higher in shrimp fed by dietary inulin. The results of this study showed that supplement of 2% of inulin has positive effects on fatty acid profile and intestinal morphology in Litopenaeus vannamei.

    Description: The objectives of the present investigation were to study the bioaccumulation of Aldrin, Diazinon and Endrin pesticides in the edible muscle tissues of Tinca tinca, Rutilus frisii kutum, Carassius auratus, Cyprinus carpio, Silurus glanis and Esox lucius that were caught at various stations in the west, east and center of the Anzali Wetland and to compare the results with the standards of the World Health Organization (WHO). The concentration of organochlorine pesticide was determined using Gas Chromatography (GC) equipped with an electron capture detector. The concentration of organophosphorus pesticide was determined using Gas Chromatography/Mass Spectrometry (GC/MS). The highest concentration of Diazinon was detected in Esox lucius from the wetland east station (20.25 ppb). Significant differences were not observed in the amounts of Diazinon and Aldrin pesticides in the muscles of fish samples in various stations (P〉0/05). The highest amounts of Endrin were observed in the muscle of Cyprinus carpio from the wetland east and west stations which were significantly different compared to that of other fish species (P〈0/05). The amount of Aldrin in the Carassius auratus was significantly different compared to that of other fish species (P〈0/05). According to the results, the amounts of Aldrin, Diazinon and Endrin were lower than the detection limits of the WHO standards. Therefore, consumers are not at risk from the point of view of food safety.

    Description: Prebiotics are non-digestive food ingredients which beneficially affect the host by selectively stimulating the growth and activity of health-promoting bacteria in the intestinal tract. This experiment was conducted to evaluate the effect of dietary supplementation of galactooilgosaccharide on the growth performances, survival and several of innate immunity parameters of rainbow trout (Oncorhynchus mykiss) larvae for 60 days. In this experiment, 360 of larvae (with average weight of 0.13±0.01g) in 4 treatments and 3 replicates (n=30 in each replicate) in a completely randomized design was divided and fed with diets containing 0, 1, 2 and 3 percent galactooligosaccharide respectively. The present results showed that highest WG, SGR and PER were observed in the diet containing 2 and 3 percent of dietary galactoologosaccharide which had a significant difference compared with other treatments (p〈0.05). The highest, survival, total protein, albumin and globulin levels were observed in treatments containing 2 percent of dietary galactooligosaccharide which showed a significant difference compared with other treatments (p〈0.05). Finally, the present results suggest that diets containing 2 percent of dietary galactooligosaccharide could improve growth, survival and innate immunity responses of rainbow trout.

    Description: In this study, the effects of Tarragon and Savory essential oils on oxidative stability of ready-to-eat shrimp (Metapenaeus stebbingi) during three months at frozen storage were investigated. Samples were treated with Tarragon and Savory essential oils and cooked by different cooking methods (frying, oven baking and steaming). Butylated hydroxytoluene (BHT) was used as a reference to compare antioxidant activities. During frozen storage, fat hydrolysis was evaluated through measuring free fatty acid value and oxidation products were measured via peroxide value and thiobarbutiric resistance substance. At the end of storage, the highest amount of free fatty acids (following the control) was observed in steamed savory treated samples (3.2% oleic acid) and the lowest amount in Savory and Ttarragon fried samples (1.11 and 1.75% oleic acid). Following BHT, the lowest amount of peroxide value was obtained from steamed shrimps treated with tarragon (0.92 meq/kg of fat). Also, thiobarbutiric acid values in fried and oven baked samples containing Savory essential oil (0.55 and 0.42 mg MA/kg of fat) was higher than samples containing Tarragon essential oil (0.44 and 0.38 mg MA/kg of fat). The results of the present study indicated that Tarragon and Savory essential oils retarded the oxidation and samples treated with Tarragon essential oil showed slower hydroperoxide and malonaldehyde formation than those of Savory-treated or the untreated samples. The best storage period of the fried, oven baked and steamed products treated with Tarragon and Savory were 1, 2 and 3 months, respectively.

    Description: Considering the importance of environmental factors on marine organisms, a survey of factors that affect the subtidal sea cucumber community was carried out in the eastern part of Chabahar Bay, a region with anthropogenic effects on marine ecosystem, from May 2007 to July 2008. Four quadrates with 100m2 area were sampled with SCUBA diving method in each region. Temperature had significant variation among the stations and seasons. There is a positive correlation (99%) between salinity and sea cucumber density and a negative correlation (95%) between turbidity and density. PCA indicated that salinity, pH, turbidity and temperature had 82.78% of all variance of the environmental factors and other factors did not exhibit such a relation with sea cucumber dispersion. Northern stations (Sepah and Kalantary) were located in same category in Fall 2007 and Winter 2008. These stations had the least pH and the highest salinity and turbidity in Fall and the highest pH and the least turbidity in Winter. Southern stations (Beheshti and Hotel Daryai) located in the same category in summer and fall 2007. These stations had the most pH and the least salinity in the summer and the most temperature and turbidity in the fall.
