In this regard, the use of this knowledge can be effective in the performance of medicinal plants in aquaculture. In the present study Aloe vera was extracted and its nanoparticles were produced. Three levels of Aloe vera nanoparticles in Siberian sturgeon (Acipenser baerii) were evaluated for the effects on growth performance, survival rate and body composition. A total of 360 Siberian sturgeon (A. baerii) with an average of 10.95 ± 0.04 (g) randomly divided into four treatment groups with three replicates each. The treatment groups were fed with diets that included 0% (control), 0.5, 1 and 1.5% of Aloe vera nanoparticles for 60 days. Weight gain, initial body weight, condition factor, feed conversion ratio, specific growth rate, protein efficiency ratio, survival rate, and body composition (protein, lipid, carbohydrate, ash and moisture) were measured and compared among the fish in the different groups. The results showed that growth indices of fish fed the Aloe vera nanoparticles were higher than the control diet, so that the difference between the control group and 1% Aloe vera nanoparticles was more than that in other treatments. In each of the body composition parameters, no significant differences were observed among the treatments and control groups (p>0.05). Considering that there are no significant differences in results between 1% and 1.5% Aloe vera nanoparticles, the results showed that adding 1% Aloe vera nanoparticles to the fish diet improves the growth factors of Siberian sturgeon.}, keywords = {Aloe Vera extract,Nanoparticles,Growth,Body composition,Acipenser baerii}, url = {https://jifro.areeo.ac.ir/article_114671.html}, eprint = {https://jifro.areeo.ac.ir/article_114671_0c1d4564522a68e05e2e5981f9ae76b2.pdf} } @article { author = {Parafkandeh, F. and Shayanfar, E. and Jamili, S. and Fazli, H.}, title = {Study of growth ring formation on scales of mullet Liza saliens in the Caspian Sea}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {2}, pages = {469-476}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114672}, abstract = {This study is attempted to compare the number of rings and circular scales that are formed during various ages on Liza saliens.

This preliminary study contributes to the species phylogeography through the study of the genetic diversity and historical demography of N. japonicus populations from the Persian Gulf and Indo-West Pacific based on cytochrome c oxidase subunit I (COI) gene sequence. Grouping of the data into phylogenetic trees indicated that the Japanese threadfin bream consists of two reciprocally monophyletic phylogroups with 2.3% net sequence divergence which may qualify as cryptic species: clade I, consists of two sub-clades (Ia and Ib) occurs in the Persian Gulf and Western India, and clade II, which is restricted to the South China Sea. Historical and demographic hypotheses were raised to explain the observed phylogeographic pattern and population structure. Among the possible key mechanisms, sea level fluctuations driven by glacial episodes of the second half of the Pleistocene Epoch appear to have played an active role in initiating major phylogeographic separation. Apart from presumptive Pleistocene vicariance, a trend of increasing genetic differences with increasing geographic distance (i.e., isolation-by-distance) and regional differences in breeding season were also proposed as possible alternative scenarios.

The study indicated that copper sulfate was effective for eradication of the snails in all conditions whether present on the wet edges / moist soil surfaces, buried in the soils or present in the aquatic environment with fish, however, with varying degrees and intensities.}, keywords = {Snail,Oncomelania quadrasi,Labeo rohita,copper sulfate,Molluscicide,Toxicity}, url = {https://jifro.areeo.ac.ir/article_114698.html}, eprint = {https://jifro.areeo.ac.ir/article_114698_b4ec9fc475980dd8413abf9d45e17a15.pdf} } @article { author = {Muhammad, A.A. and Farooq, S. and Rabbaniha, M. and Jahangir, S. and Malik, A. and Hameed, A. and Baloch, A.J.}, title = {Short communication:Current fishery status of ribbonfish Trichiurus lepturus Linnaeus, 1758) (Trichiuridae) from Makran coast (northeast Arabian Sea)}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {2}, pages = {815-821}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114699}, abstract = {}, keywords = {length-weight relationship,Ribbon fish,FISHERY}, url = {https://jifro.areeo.ac.ir/article_114699.html}, eprint = {https://jifro.areeo.ac.ir/article_114699_e42d677f497ea51192036db7381dc40e.pdf} } @article { author = {Dinh, Q.M.}, title = {Short communication: Morphometric, growth and condition factor variations of Boleophthalmus boddarti in the Mekong delta, Vietnam}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {2}, pages = {822-831}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114700}, abstract = {}, keywords = {Boleophthalmus boddarti,Mudskipper,Isometric growth,length-weight relationship,Condition factor}, url = {https://jifro.areeo.ac.ir/article_114700.html}, eprint = {https://jifro.areeo.ac.ir/article_114700_560447332ba1f3af0b35fc993a7a8858.pdf} } @article { author = {Khani, M. and Soltani, M. and Shamsaie Mehrjan, M. and Foroudi, F. and Ghaeni, M.}, title = {Short communication:The effects of Chlorella vulgaris supplementation on growth performance, blood characteristics, and digestive enzymes in Koi (Cyprinus carpio)}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {2}, pages = {832-843}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114701}, abstract = {}, keywords = {Koi carp,Chlorella vulgaris,Growth performance}, url = {https://jifro.areeo.ac.ir/article_114701.html}, eprint = {https://jifro.areeo.ac.ir/article_114701_b6b127b4ee25d7074a9d045a9911145f.pdf} } @article { author = {Nanvazadeh, H. and Khodayar, M.J. and Jahangiri, A. and Rahbar, N. and Behfar, A. and Dehbashi, F.}, title = {Short communication: Determination of total mercury in common carp, Cyprinus carpio, large scaled barb, Barbus grypus, tiger tooth croaker, Otolithes ruber and from surface waters in Khuzestan, Iran}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {2}, pages = {844-850}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114702}, abstract = {}, keywords = {Fish,Mercury,muscle,Water,Khuzestan}, url = {https://jifro.areeo.ac.ir/article_114702.html}, eprint = {https://jifro.areeo.ac.ir/article_114702_92946d507d1f4dcad25df07b10c45f3e.pdf} } @article { author = {Khatami, S. and Valinassab, T. and Kaymaram, F.}, title = {Short communication: Morphometric variation and growth rate of Uroteuthis duvaucelii (Cephalopoda: Loliginidae) in the Persian Gulf and Oman Sea using gladius increments}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {2}, pages = {851-857}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114703}, abstract = {}, keywords = {Uroteuthis duvaucelii,Gladius,Increments,Persian Gulf,Oman Sea}, url = {https://jifro.areeo.ac.ir/article_114703.html}, eprint = {https://jifro.areeo.ac.ir/article_114703_358b1db700f22cb4b65e3ae814f5b14a.pdf} } @article { author = {Caglar, M. and Pala, G. and Selamoglu, Z.}, title = {Short communication: Study on epilithic diatoms in the Balikli Tohma Creek (Darende/Malatya in Turkey)}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {2}, pages = {858-868}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114704}, abstract = {}, keywords = {Balikli Tohma Creek,Diatom,Epilithic,Algae}, url = {https://jifro.areeo.ac.ir/article_114704.html}, eprint = {https://jifro.areeo.ac.ir/article_114704_5e068560e45c0410a4b5887822235218.pdf} }
