    Low dose of anti-VEGF causes side effects [Medical Sciences] (2016)
    National Academy of Sciences
    Details
    Publication Date: 2016-04-13
    Description: Anti-VEGF–based antiangiogenic drugs are designed to block tumor angiogenesis for treatment of cancer patients. However, anti-VEGF drugs produce off-tumor target effects on multiple tissues and organs and cause broad adverse effects. Here, we show that vasculatures in endocrine organs were more sensitive to anti-VEGF treatment than tumor vasculatures. In thyroid,...

    Study on brood stock management of Litopenaeus vannamei using imported post larvae (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In order to domesticate Litopenaeus vannamei as a solution to single species shrimp aquaculture of Penaeus indicus and to reduce risk of shrimp culture in emergency cases, this study was carried out. Initially the postlarvae reared from imported L. vannamei were cultured. After culture season the adult shrimps were transported to greenhouse ponds for wintering. It is then relocated to hatchery saloon. After eye stalk ablation and maturation the female brood stocks were introduced to matured male for copulation at ponds. During the study period, male and female shrimps attained full maturation at end – April by temperature over 25ºC, the copulation process was started significantly. Finally of the 12 instances of copulation, one instance resulted nauplii production. The best maturation was observed at 28 ֯C ±1 and salinity30 to 33PPT and pH of 8 to 8.3 Fresh sea worms and squid showed the highest effect on fecundity in brood stocks. Besides, the spring season was obtained to be the best period for brood stock production in Bushehr province.

    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: For the successful breeding of western white shrimps (Litopenaeus vannamei) brooders (females and males), we used cuttle fish (Sepia pharaonis) and sand worm (Perinereis nuntica) of Persian Gulf as principle feeds, 3 times a day, and from cow livier and edible bivalve meat (Solen brevis) of Persian Gulf, as secondary feeds, 1 time a day. Nutritional value of Sepia pharaonis, Perinereis nuntica and Solen brevis, with determination of the amount of fatty acids such as arachidonic acid (20:4n-6), stearic acid (18:00), oleic acid (18:1n-9), palmitic acid, palmitoleic acid (16:1n-7), eicosapentaenoic acid (20:5n-3) and docosahexaenoic acid, essential amino acids inclusive arginine, lysine, leucine, isoleusine, threonine, valine, histidine, phenylalanine, methionine, tryptophane and crude protein, crude fat, crude fiber, ash and moisture were done in laboratory. The results showed that, the amount of essential amino acides and nonessential amino acides (in the more causes) in Sepia pharaonis were more than Solen brevis and in Solen brevis more than Perinereis nuntica. Only nonessential amino acides, glysine and alanine in Solen brevis were more than Sepia pharaonis. Also in chemical analysis of wet feeds determined that, crude protein percent in cattle fish was 2.9 times and 2.2 times more than Solen brevis and Perinereis nuntica, respectively. The crude fat in cattle fish was 2.1 times and 1.6 times more than Solen brevis and Perinereis nuntica respectively. Tottaly, the amount of essential fatty acides in Sepia pharaonis and Perinereis nuntica were more than Solen brevis, and in Sepia pharaonis and Perinereis nuntica were almost, equal. Total lipids of Sepia pharaonis, Perinereis nuntica and Solen brevis determined 7.92, 5.90 and 3.63 percent respectively. Totally the percent of fatty acids in cattle fish and Perinereis nuntica is almost equal and was more than Solen brevis meat. We can noted that, the Sepia pharaonis and Perinereis nuntica are suitable as principle feed and Solen brevis and cow livier, as secondary feed for L.vannamei broodstock maturation.

    Investigating the application of spawning shelter of Cattle fish for its enhancement of resources (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In this project,four types of structures,of 40 number was investigated.In a six month period,the structures were inspected 13 times.The total weight and number of eggs hatched on the structures were estimated to be 214.1kg and 94944 respectively.The weight and number of eggs settled on trap types were 141.9 and 60982 respectively,whereas,The eggs on cubical structures were estimated 56.7kg and 27088 ,on pyramid structures 7.9 and 3941 and then also were 6.9kg and 3280 eggs on cylindrical structures respectively.It is also estimated that 358 eggs were settled on The connecting line weighting 0.5kg.In this report four types of structures was compared.As a result,the trap, cubical, pyramid and cylindrical structures had contributed to the settelment of 66,27,4 and 3 percent of eggs in weight. While 64,29,4 and 3 percent of eggs in number was settled on these structures respectively.Thus it is concluded that the trap structures fallowed by cubical ones had acted more effectively relative to other two.If based on the results of other studies,we assume 80% survival rate of eggs and average weight of 1.2kg of survival growth cuttlefish , then it can be calculated that 160 structures can contribute to 91 tons increase in cuttlefish stock in one area of 4 to 5 acre.It is obviaus that by planning an annual increase of the structures,it is passible to attract more spawners to spawn and produce more larvae.Moreover,The old structures will be covered by corals and barnacles and become amore stalie and attractive spawning ground for cuttlefish.

    A survey on effects of shrimp aquaculture on the coastal waters of Bushehr (Helleh and Mond) (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: The effects of aquaculture industry on the environment were evaluated by studying the water quality of Bushehr costal water during culture season 2005 and 2006. The variations of selected parameters such as total phosphorus, ammonia, chlorophyll a, pH, salinity and... Were monitored in effluent canal, influent canal and open sea in Helleh and Mond regions as monthly. Following occurrence of White Spot Disease (W.S.D) in the shrimp ponds of Bushehr province, shrimp culture suspended and entrance of effluent waters completely were blocked since August 2005, despite the absence of aquaculture sewage evaluation of environment and sampling were continued. During releasing of sewage of shrimp ponds to the coastal waters of Bushehr in Jun 2005, the average amount of ammonia in Helleh and Mond were obtained to be 0.161 mg/l and 0.194 mg/l, however the average amount of total phosphorus in Helleh and Mond regions were 0.149 mg/l and 0.043 mg/l, respectively. Although effluent water suspension, amount of ammonia and total phosphorus were increased in both region especially in June 2006. Comparing present data in Jun 2005 and recorded data from culture period 1997-2003 with permitable range of municipal and aquaculture waste show that; aquaculture industry on both regions have not had any obvious negative effect on the coastal waters of Bushehr but it seems if other sources of pollutions in the region is not controlled, then the aquaculture industry can contribute to occurrence of environmental problems.

    Determination of LC50 of copper in Litopenaeus vannamei (2018)
    Details
    Publication Date: 2021-05-19
    Description: We determined the LC50 of copper (as CUSO4) and it's Maximum Allowable Concentration (MAC) for Litopenaeus vannamei. The study was performed in 2003 for which bioassays were used for acute toxicity tests in a period of 96 hours during which water parameters such as water temperature, pH, dissolved oxygen, hardness, alkalinity were also measured. Ten treatments and three replicates for each treatment were used. A LC50 of 86.71, 27.28, 7.98 and 3.90mgi1 and also Maximum Allowable Concentration of 8.671, 2.728, 0.798 and 0.390mgi1 were determined at 24, 48, 72 and 96 hours post exposure. Results showed that L. vannamei is relatively resistant to copper. Hence, short period application of copper to white shrimp farms for controlling algal bloom is judged harmless to the fish.

    Molecular identification of bacterial and fungal pathogens in certain disease-free shrimp (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: At present, the aquaculture industry to provide proper instructions in the field of health management, including production of Specific Pathogen Free shrimp (SPF), require sensitive and reliable methods for the detection and identification of pathogenic microorganisms. Molecular methods which used in the detection of microorganisms have a high discriminatory power in the taxonomy and in relation to libraries in the world. On the other hand, the accurate identification of microorganisms, providing the genetic data bank of shrimp pathogens and maintenance of these strains is the step to promote further research on the mechanisms of pathogenesis of pathogens, diagnosis, treatment, prevention of disease, identify indigenous production kits, diagnosis re emerging and emerging diseases and their origin. Therefore, in this project, by using ribotyping technique, native isolated pathogenic bacteria and fungi were identified and recorded in the gene bank database center. During sampling of shrimp and water of Specific Pathogen Free shrimp center, 40 bacterial strains were isolated, which 8 of them had the most frequency and identification based on 16S rDNA sequencing was performed. Bacteria identified are: Vibrio nigripulchritudo strain IS013(GenBank:KP843725), Vibrio brasiliensis strain IS014 (GenBank:KR186076), Vibrio rotiferianus strain IS015 (GenBank:KR186077), Vibrio azureus strain IS012 (GenBank:KJ018724.1), Vibrio owensii strain IS016 (GenBank:KR186078), Agarivorans gilvus strain IS017 (GenBank:KR186079), Vibrio brasiliensis IS018 (GenBank:KR186080) and Vibrio alginolyticus strain IS019 (GenBank:1817854), which were recorded in The World Bank genes. In this study fungal isolates were not detected.

    Effect of different dietary levels of plant protein on growth indexes of White Leg shrimp (2018)
    Details
    Publication Date: 2021-05-19
    Description: The influence of different dietary levels of plant protein (30, 50 and 70%) on growth indices of White Leg Shrimp (Litopenaeus vannamei) fed with an original 38 percent protein was assessed and compared with that of the commercial shrimp diet. The average weight gain at the end of the culture period in treatment 1 (30% plant protein and 70% animal protein), was 5.89 plus or minus 0.06 grams, for treatment 2 (50% plant protein and 50% animal protein), was 6.22 plus or minus 0.25 grams, for treatment 3 (70% plant protein and 30% animal protein), was 6.19 plus or minus 0.24 grams and for the control treatment (20% plant protein and 80% animal protein), was 6.42 plus or minus 0.40 grams. Our study of the influence of experimental and control diets on growth indices including growth rate (GR), food conversion ratio (FCR), protein efficiency ratio (PER), specific growth rate (SGR), and average daily gain (ADG), demonstrated that the indices were better in the control compared to the treatments. No significant difference was found among the treatments and between the treatments and the control for the indices (P〉0.05). The percent of net protein utilization (NPU) in treatment 1 was significantly more than other treatments (P0.05). We also found that the application of diets containing 50% plant protein (with 20% soybean meal), and 70% plant protein (with 41.72% soybean meal), can decrease diet costs. Cost of one kilogram of pellet, in treatments 1, 2, 3 were, 83.3%, 68.3% and 53.3% lower than the control diet respectively. Decrease of cost in treatment 2 and 3, in comparison to control in terms of lowering shrimp production cost is very important.
