Unfortunately, all these procedures are practically found to be slow and stressful to Clarias batrachus, including the popular caudal vein approach, likely due to the small size of caudal veins relative to the size of the species. In line with the universal ethical recommendations for taking blood from small research animals, we propose an alternative one-operator approach for C. batrachus that is simple, rapid and without the need to sacrifice the fish as with other methods. This procedure targets the dorsal aorta (a relatively larger blood vessel) in a sedated fish, punctured by inserting a needle directly from the anterior part of the anal fin about 2-5 mm behind the genital papilla, to draw the desired amount of blood. The technique is a one-operator procedure not requiring the help of an assistant or any special equipment to restrain the fish. The operation of the protocol is unique since it permits the continuous collection of blood from the same experimental fish over a varied time course and reduces the need for a large number of replicate animals.

The study showed that the maximum weight was in fish fed diet containing 8% of S.O and also the maximum specific growth rate (SGR) (D3, p < /em><0.05) was obtained for this group. The highest rate of daily weight gain (DWG) was obtained for D3 which was significantly (p < /em><0.05) much more than that for D4, D6 and D5 (the lowest increase). The highest length gain (LG) was observed in D3 which was significantly more (p < /em><0.05) in comparison with the other treatments tested. The survival rate was over 80% in all test groups and showed no significant difference (p < /em>>0.05). At the end of the period, fish were evaluated for estimated analysis of the tissue.

Plankton sampling from inshore and offshore sites and the exposed and sheltered sides of the reefs resulted in the collection of 2048 larvae representing 49 different fish taxa belonging to 11 orders and 36 families of fish. The overall density of fish larvae at all sites was calculated as the larvae numbers in 1000m-3 and there was a significant difference in larval density between sites and months. Most larvae were collected in the warmer months of the year from May to August. The inshore sheltered site (H3) is significantly different from all other sites in having the highest density with 2824 larvae 1000 m-3, whereas the inshore exposed site had the lowest density of all sites (621 larvae 1000 m-3). Number of species varies significantly among sites. Data of the seasonal and regional occurrence of fish larvae obtained from the present work could be very valuable for fisheries management. It also gives an idea about how larval stages of reef fish are distributed in regard to the reef topography and the distance from the shore. }, keywords = {Fish larvae,exposure,Coral reef,dispersal,Red Sea}, url = {https://jifro.areeo.ac.ir/article_114719.html}, eprint = {https://jifro.areeo.ac.ir/article_114719_4128009267a65abbade1160dac92d152.pdf} } @article { author = {Zadmajid, V. and Mohammadi, Ch.}, title = {Dietary thyme essential oil (Thymus vulgaris) changes serum stress markers, enzyme activity, and hematological parameters in gibel carp (Carassius auratus gibelio) exposed to silver nanoparticles}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {3}, pages = {1063-1084}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114720}, abstract = {Gibel carp (Carassius auratus gibelio) juveniles with an average weight of 8.73± 2.1 g were fed a basal diet (control) and three experimental diets (T200, T400 and T800), containing 200, 400 and 800 mgkg-1, respectively of thyme essential oil (Thymus vulgaris) for six weeks. After six weeks feeding trial, both control and thyme essential oil-added feed groups were exposed to sub-acute toxicity of silver nanoparticles (Ag-NPs) for a period of 96 h. At 96 h after exposure, the number of erythrocytes (RBC), leucocyte (WBC), hematocrit (Hct), hemoglobin (Hb), the differential leukocyte count in blood and alanine aminotransferase (ALT), aspartate aminotransferase (AST) activity, HDL-cholesterol, LDL-cholesterol, cortisol and lactate in serum were measured. The results revealed feeding a thyme essential oil diet significantly conferred resistance to oxidative stress with sub-acute toxicity of Ag-NPs. Thyme essential oil enhanced the RBC and WBC count, hematocrit and hemoglobin content, at both low (T400) and high doses (T800). Biochemical analysis showed that serum ALT and AST activities, and LDL-cholesterol in the thyme essential oil-added feed groups were significantly reduced with increasing dietary thyme essential oil. Plasma HDL-cholesterol was significantly elevated by a high-dose of dietary thyme essential oil (T800). Furthermore, cortisol and lactate levels in serum significantly decreased throughout the thyme essential oil-added feed groups compared to the control. In summary, the use of thyme essential oil at 400 and 800 mgkg-1, as dietary supplements, has potential to decrease oxidative stress of gibel carp providing resistance to non-fatal effects of pollutant by Ag-NPs.  }, keywords = {Silver nanoparticles,Gibel carp,Thyme essential oil,Plasma electrolytes,Hematological parameters}, url = {https://jifro.areeo.ac.ir/article_114720.html}, eprint = {https://jifro.areeo.ac.ir/article_114720_0a9749811f2fb13645ccc64913098ca6.pdf} } @article { author = {Daniali, S.R. and Soltani, M. and Kamali, A. and Shamsaei, M.}, title = {The effects of Oncorhynchus mykiss culture on the limnological conditions of Hanna Reservoir, Isfahan, Iran}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {3}, pages = {1085-1097}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114721}, abstract = {This study was conducted at the Hanna Reservoir located in the southwest of Isfahan Province.

Water quality, zooplankton, benthos and sediments were monitored at sites of 20 m depths to determine the effects of rainbow trout cage culture on the lake environment. Oxygen depletion occurred in the vicinity of the farms due to respiration of the farmed fish. Zooplankton had stronger nutritional value in all six ecosystems of the Hanna Reservoir, and in seasons during which fish feed on these nutritional sources, breeding occurs with higher efficiency. Benthic invertebrates were rare at all six sites of the lake.

Based on physicochemical analysis of water at 2 day intervals, effective parameters were maintained at a required range for the wellbeing of the shrimp during the experiment. Results of the experiment show that Sargassum sp. can be used as a binder in shrimp feed ingredients with significant differences between treatment pellet stability and water absorbance percent in sea water.Although initial biomass, SGR and survival rate showed no differences between treatments, but final biomass , biomass gain, FCR, shrimp flesh color and cholesterol levels revealed significant differences between treatments (p < /em><0.05). The diet with the highest level of seaweed (A) showed not only the best growth performances, survival rate, change in the flesh color desirable to the consumers and decreased cholesterol level in shrimp, but also has the best binder property for shrimp pellet making. }, keywords = {Sargassum ilicifolium,Replacement,Litopenaeus vannameii,Protein resource,Oman Sea}, url = {https://jifro.areeo.ac.ir/article_114722.html}, eprint = {https://jifro.areeo.ac.ir/article_114722_583cde7998f832c745d7fed4a097258e.pdf} } @article { author = {Gökoğlu, M. and Teker, S. and Julian, D.}, title = {Short communication:First report of thresher sharks (Alopiidae) in the Gulf of Antalya}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {3}, pages = {1108-1113}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114723}, abstract = {}, keywords = {Thresher sharks,Alopiidae,Alopias superciliosus,Alopias vulpinus,Gulf of Antalya}, url = {https://jifro.areeo.ac.ir/article_114723.html}, eprint = {https://jifro.areeo.ac.ir/article_114723_6aab6254d235d1300573c82fc23edc70.pdf} } @article { author = {Ara, M. and Farooq, S. and Rabbaniha, M. and Ali Muhammad, A.}, title = {Short communication:First report of cyclopoid copepods (oithonidae) from north-eastern Arabian Sea, Karachi, Pakistan}, journal = {Iranian Journal of Fisheries Sciences}, volume = {17}, number = {3}, pages = {1114-1122}, year = {2017}, publisher = {Agricultural Research,Education and Extension Organization}, issn = {1562-2916}, eissn = {2322-5696}, doi = {10.22092/ijfs.2018.114724}, abstract = {}, keywords = {ZOOPLANKTONS,Copepods,Cyclopoids,Oithona,Arabian Sea,mangrove forests,Pakistan}, url = {https://jifro.areeo.ac.ir/article_114724.html}, eprint = {https://jifro.areeo.ac.ir/article_114724_c76b0f78962c433686defb12295c8829.pdf} }
