    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: This study was conducted to determine some heavy metals concentrations (in water and sediments) and oil pollution (in sediments) in the southern Caspian Sea (Mazandaran Coast-Kelarabad). Surface sediments samples were collected at three stations from autumn 2011 to winter 2012. In addition, water samples were collected from autumn 2014 to summer 2015. All samples were perpaired by digesting and extracting processes and then determined using Atomic Absortion Spectroscopy and High Performance Liquid Chromatography instruments. Results of current study showed that annual mean contents of Zn, Cu, Cr, Ni, Pb, Cd, Hg and standard error (±SE) of water were registered as 8.38 (±5.69), 10.90 (±4.95), 7.17 (±1.20), 4.50 (±0.90), 22.29 (±7.10), 4.83 (±2.30) and 0.131 (±0.07) µg/l, respectively. The mean values of the examined heavy metals in water samples were obtained in order of Pb〉Cu〉Zn〉Cr〉Cd〉Ni〉Hg. The annual mean contents and standard errors (±SE) of surface sediments were observed 59 (±3), 25 (±1), 42 (±2), 28 (±1), 14 (±1), 0.16 (±0.06) and 0.020 (±0.005) µg/g.dw for Zn, Cu, Cr, Ni, Pb, Cd and Hg, respectively. Also, the mean values of the examined heavy metals in surface sediment samples were noted in this rank Zn〉Cr〉Ni〉Cu〉Pb〉Cd〉Hg. The mean values of Igeo were ranked as IgeoPb〉 IgeoZn〉 IgeoCu〉 IgeoCr〉 IgeoNi〉 IgeoCd and for enrichment factor were EFPb〉EFZn〉EFCu〉EFCr〉EFNi〉EFCd〉EFHg. The mean values of the contamination factor were recorded as CFCd〉 CFPb〉 CFZn〉 CFCu〉 CFCr〉 CFNi〉 CFHg. The annual mean contents of PAHs and standard errors (±SE) of surface sediments were registered as 2.81 (±0.73) µg/g.dw; among 16 compounds of PAHs, Fluranthene was contained maximum values (2.79±0.96 µg/g.dw). In addition, the concentration of naphthalene was below limit of detection. The Hazard Quotations (HQs) of all PAHs were calculated higher than unit in surface sediments. In conclusion, the results revealed that the mean concentrations of all heavy metals (except Cu) of water were below the threshold levels but maximum concentrations of Cu, Pb and Cd were above of the regulatory limits associated with toxicological effects, which repersented polluted condition in this area. Concentation of Cd in sampled sediments based on geoaccumulation index (Igeo) showed modrated polluted conditions for this regions, but other heavy metals were in unpolluted status. Cu, Cr, Ni and Cd contents of sediments in the samples based on enrichment factor (EF) showed no enrichment conditions for this region, but other heavy metals (Zn and Pb) were in minor enrichment status. The Caspian Sea sediments were classified as low polluted based on CF, Cd and PLI. The results revealed that the 16PAHs concentrations of sediments were below the threshold levels (except TEL) and mostly of pyrogenic (85%) sources, which represented unpolluted condition in this area. According to results of the evaluation of risks to the health of 16PAHs suggest that there is risk for the existing biota. Also, the Caspian Sea sediments were classified in Class 3 (Poor). According to anthropogenic sources of some heavy metals and PAHs of sediment, it is essential that the management and development of the cage aquaculture industry in the Caspian Sea to be made with environmental considerations and cautions.

    Details
    Publication Date: 2021-05-19
    Description: The Todebin dam reservoir has been constructed in central part of Abhar in the Zanjan province which has been studied with aquaculture purpose. This study was conducted on biotic and abiotic factors. The plankton, benthos and fishes were identified and the parasitology and bacteriology studies were performed on the lake fishes. Then the fisheries potential of the lake was calculated in respect of final fish farming amount and the fish releasing. The results showed the Bacillariophyta was dominated ِduring the study. the highest abundance of phytoplankton was between 2.1 and 12.5 million cells.l-1 in the upper layer of lake as compared with the lower layer. The genus Cyclotella and Dinobryon belong to phytoplankton and Keratella and Polyathera belong to zooplankton were dominanted abundance. The mean biomass of benthos was varied from 5.5 to 29.5 g.m -2 and the Chironomidae had the most abundance. The ichtiology survey showed the presence of four cultured species and the Goldfish. The hydro-chemical results indicated no restriction for aquaculture activity. The oxygen average was more than 8 mg/l. The average of phosphate, nitrogen and hardness were measured 0.09±0.04, 2±0.8 and 237±94.5 mg/l., respectively. For the most hydrochemical factores, the values were significantly different between upper and bottom layers of the lake. The oxygen production and Chl-a amount were measured about 0.73 mg/l. and 7/03 µg/l., respectively. According to climatic restrictions, the cold fish culture is preferred than to culture of warm fishes. While the natural capacity of the lake was about 5 tones to warm fish culture, the fish production of trout was estimated about 40 tones. This volume will be available during four months periods and twice a year.

    Analyze the Types and Methods Suitable Nutrition in Introducing a Variety of Fish Cages in the Southern Part of Caspain Sea (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-12-05
    Description: Regarding the fish farming in cages, taking into account all nutritional requirements appropriate to the needs of aquaculture is essential in order to minimize damage to the environment and achieve maximum growth. Fish nutritionists should be aware about the analysis of ability to digest and absorb nutrients in the diet to prepare and adjust the diet according to the needs of aquaculture. Food must also have appropriate physical properties for food intake with minimal loss of nutrients in the water. Inadequate resources with low quality or energy consumption within food, reduced the growth performance and increased the excretion of nitrogen in the environment. Food must be designed so that the balance of minerals in food will help maintain osmotic pressure within the body of fish in salty water. Food requirements and efficiency of food conversion ratio (FCR) is variable by changing environmental conditions (dissolved oxygen, temperature, water quality, flow rate, light intensity ,day length). The fish of cages are feeding by floating pellets which have the ability to stand in the water column. The floating pellets allows the fish to have sufficient time and opportunity for finding food. But sinking pellets pass rapidly from the cage and are inaccessible to fish. According to the Caspian sea conditions is better the extruded food equipped with Hygenizer to be used that a portion of it remains on the water surface and part of it moves gently down with an immersion mode in the water column (Softly deposited) for fish consumption. The amount, number and time of feeding are important factors to assess the nutritional activities. In general, fish feed from dry food between 2 to 3 percent of their body weight. Food consumption was also varied due to the quality of the food and fish physiological factors such as age, size, stage of life and stress level. Fish food distribution being fed manually or by means of demand, launcher and automatic feeding. The farm managers should pay attention to the things like water flows in the cage, wind, fish appetite, consolidated flows in the cage during food distribution as well as food storage in dry places with proper ventilation system to prevent the growth of fungi and insects activities to prevent loss of food. Also, adding antioxidants to the 100150 ppm when storing dry foods including the important cases particularly in prevention of fish liver lipoidosis disease is considered.

    Evaluation of stocking density vannamei shrimp Litopenaeus Vannamei (Boone, 1931) in cultuering with brackish water of Caspian Sea (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Recently, the development of aquaculture has focused on the use of seawater, because of freshwater crisis in the world. Whiteleg shrimp (Litopenaeus Vannamei) is one of the most important species for aquaculture development, because of tolerance and adaptation to different ecological conditions. One of the advantages of species in aquaculture, compatibility status is dense in the rearing period. In this study, the effect of different densities (45/m2 , 50/m2 , 55/m2 and 60/m2 ), of primary stock whiteleg shrimp postlarvae (PL12) on the growth and survival rate were evaluated. Brackish water (10.52±0.43 ppt) was providing from Caspian Sea. The experiments were performed in 12 circular concrete pond with a sandy bed (area: 78m2 ) in four treatments and three replications for each treatment. The experiments performed in a 75-day period. In this study, the water temperature was 27.4±1.79°C. The results showed statistically difference in growth parameters and survival rate among experimental treatments (Duncan test, P〈0.05). Therefore, with high levels of density, has decreased the amount of weight gain and survival rate (SR), specific growth rate (SGR) and average daily growth (ADG). In addition, the treatments were different variations of FCR (P〈0.05) and not depend on the primary stock density of postlarvae. In low density (45/m2 ) were observed the highest growth (SGR=11±0.04 and ADG=0.25±0.01 gr/day/ind.), survival rate and calculate the amount of production per 78m2 equal 43.6±3.3kg (5596±433kg/ha). Therefore, It is possibility that there is commonly increasing primary stocking of density about L. Vannamei postlarvae culture in Iran.

    Details
    Publication Date: 2021-05-19
    Description: The "fisheries and aquaculture industry innovation system" is one of the subsystems of Agricultural innovation system (AIS), also has many characteristics of that system .Since this section contains most of the components and AIS institutions, it can be examined as a part of the national innovation system. Due to the structure of the innovation system in the fishery system, a set of functions and institutions of this system are most important .It is therefore important that the system be analyzed and by reviewing the existing state institutions and functions of this system, the main problems and challenges identified. Understanding of the institutions and functions of fishery innovation system and analyze its problems and provide an improved model for fishery innovation system, is most activity in shaping major policy innovation in fishery sector. This step is very important to conduct innovative activities in the fishery sector. In this study, using a system perspective, the current status of the various factors affecting fishery development was assessed and the main drivers and challenges and solutions to improve the detection and analysis was provided. The results show that during the past eighty years, a number of research centers and educational institutions in the public sector have been developed .but this system, despite having considerable institutional capacity, is still in the middle stages of institutional development. In these years, the policy approach was linear, not system approach, so little attention has been to the development of science and technology intermediary institutions, coordinator organizations, venture capital funds, and the institutions of technology transfer ,particularly in the public sector.

    Effect of different levels of n-3 HUFA on larvae culture performances of Beluga (Huso huso) fish (2018)
    Details
    Publication Date: 2021-05-19
    Description: The effects of n-3 highly unsaturated fatty acids (n-3 HUFA) were studied on Beluga (Huso huso) fish larvae by feeding fish larvae with live food enriched with 4 different oils (ICES 30/4, tuna eye oil, flaxseed oil and linseed oil) containing different levels of n-3 HUFA including 27.19, 20.33, 12.71 and 0.39 mg g-1 dry weight of oil, respectively. Fish larvae weighing 30.00±2.00 mg were randomly divided into 12 groups of 150 fish each and triplicates fed the 4 experimental diets for 3 weeks. There were no differences in survival rates, but significant differences were found in growth rates and fatty acid composition of the fish larvae after 30 days. Fish fed low levels of dietary n-3 HUFA (0.39 mg g-1 DW) showed poor n-3 HUFA contents but these fatty acids improved with the elevation of the n-3 HUFA levels in the diet up to 20 mg g-1 DW. Fish fed the flaxseed oil showed the highest level of crude lipid 15.00±3.01). Results showed that tuna eye oil and ICES30/4-enriched live food (4.83 ±1.29 and 4.61 ±0.99 mg g-1 DW, respectively) showed the highest n-3 HUFA content for sturgeon fish larvae.
