Understanding habitat preference is important in many terms such as management of fish populations, assessment of river health, river restoration, etc. In this regard, we chose Capoeta razii , one of the most abundant species in the Caspian Sea rivers, to study its habitat preferences in different ages.  As pilot, Zarem Stream, a main tributary of Tajan River with low pressures and high habitat diversity, was selected. After collecting fish species in different random points, the environmental variables in the sampled areas were measured immediately after sampling. Habitat preferences analysis for different ages of this species showed that each age has almost own specific preference in terms of flow velocity, depth as well as abiotic and biotic substrate.
了解生境偏好在许多方面都很重要,如鱼类种群管理、河流健康评估、河流恢复等。因此,我们选择里海河流中最丰富的物种之一Capoeta razii,研究其不同年龄的栖息地偏好。作为试点,选择了Tajan河的主要支流Zarem溪,该溪气压低,栖息地多样性高。在采集不同随机点的鱼类后,采样后立即测量采样区域的环境变量。不同年龄的生境偏好分析表明,每个年龄在流速、深度以及非生物和生物基质方面几乎都有自己的特定偏好。

This checklist aims to reviews and summarize the results of the systematic researches on the Persian Gulf ichthyofauna that has been carried out for more than 200 years. Since the work of C. Niebuhr, a Danish biologist in the 18th century, the number of valid species has increased significantly and the systematic status of many of the species has changed, and reorganization and updating of the published information has become essential. Here we take the opportunity to provide a new and updated checklist of fishes of Persian Gulf based on literature and taxon occurrence data obtained from natural history and new fish collections. The total confirmed fish species of Persian Gulf comprise 743 species, 131 families, 444 genera and 27 orders. In the class Chondrichthyes, the most diverse family is Charcharhinidae with 23 species (41.89%), followed by Dasyatidae with 15 species (31.08%). Within the class Actinopterygii, Gobiidae with 65 species (9.70%), Carangidae with 45 species (6.27%), Serranidae with 25 species (3.73%), Apogonidae with 25 species (3.73%), Lutjanidae with 23 species (3.43%) and Blenniidae with 23 species (3.43%) are the most diverse families in the Persian Gulf.
本检查表旨在回顾和总结200多年来对波斯湾鱼类区系的系统研究成果。自18世纪丹麦生物学家C.Niebuhr的工作以来,有效物种的数量显著增加,许多物种的系统地位发生了变化,重组和更新已发表的信息变得至关重要。在这里,我们借此机会提供了一份新的、更新的波斯湾鱼类清单,该清单基于从自然史和新的鱼类收藏中获得的文献和分类单元发生数据。波斯湾已确认的鱼类共有27目131科444属743种。在软骨鱼纲中,种类最多的科是Charcharhinidae,共有23种(41.89%),其次是Dasytaidae,有15种(31.08%)。在放线鸟纲中,Gobidae有65种(9.70%),Carangidae有45种(6.27%),Serranidae有25种(3.73%),有23种(3.43%)的鹿科和23种(34.3%)的布伦尼科是波斯湾最多样化的科。

The present study gives an updated checklist of the species belonging to the family Haemulidae. Information on the status of 402 nominal species, including 131 valid species, 235 synonyms, 20 incertae sedis , 10 nomina nuda , and six non-haemulid species, are given. Original spelling of the names, authorship and date of publication have been checked against the Eschmeyer Catalog of Fishes on line (ECoF) (Fricke et al. 2019). The valid genera and species are listed alphabetically in the two currently recognized subfamilies, together with their synonyms, type information, and distributions. Examination of the original descriptions of previously unplaced species led to identification of three senior synonyms and 28 junior synonyms. The senior synonyms are: Dentex diplodon Bowdich, 1825, Lutjanus brasiliensis Bloch & Schneider, 1801, and Pristipomus brasiliensis Lichtenstein, 1823. They represent available names which are never been used ( nomina oblita ) and predate the following well established fish names which are here regarded as nomina protecta : Pomadasys perotaei (Cuvier, 1830) , Rhonciscus crocro (Cuvier, 1830), and Brachygenys chrysargyreum (Gunther, 1859). Mylacrodon Regan, 1903 is a synonym of Boridia Cuvier, 1830.
本研究提供了一份最新的血蜱科物种清单。提供了402个命名物种的状况信息,包括131个有效物种、235个同义词、20个景天属(incertae sedis)、10个裸名属(nomia nuda)和6个非血细胞物种。姓名、作者和出版日期的原始拼写已根据Eschmeyer在线鱼类目录(ECoF)进行了检查(Fricke等人,2019)。在目前公认的两个亚科中,有效的属和种按字母顺序列出,以及它们的同义词、类型信息和分布。对先前未定位物种的原始描述进行检查,确定了3个高级同义词和28个初级同义词。高级同义词有:Dentex diplodon Bowdich,1825,Lutjanus brasiliensis Bloch&Schneider,1801,和Pristipomus brasilienis Lichtenstein,1823。它们代表了从未使用过的可用名称(nomia oblita),并且早于以下公认的鱼类名称,这些名称在这里被视为nomia protecta:Pomadasys perotaei(居维叶,1830)、Rhonciscus crocro(居维耶,1830年)和Brachygenys chrysrgyreum(Gunther,1859年)。Mylacrodon Regan,1903是Boridia Cuvier,1830的同义词。

Landmark-based geometric morphometric (GM) analysis was carried out in the present study on the species of the family Leiognathidae. Pattern of shape variation along the axes of the principal components and canonical variates were analyzed after the General Procrustes analysis. Canonical variates analysis confirmed the occurrence of eleven species of the family Leiognathidae along the Gopalpur-on-Sea, Odisha coast. Further, inter-specific shape variation among the species of the family were carried out using Discriminant function analysis, which would help us to understand the morphological divergence with respect to shape.

Underwater Visual Census (UVC) and Baited Remote Underwater Video (BRUV) are broadly used methods to study fish assemblages in marine and estuarine environments. This study compared the results of BRUV and UVC methods for assessing seasonal trends in coral reef fish assemblages in a marginal reef in the northern Persian Gulf. In doing so, seasonal surveys of coral reef fishes were done using BRUV and UVC methods. Comparison of assemblage metrics driven from each method indicated that both methods may reveal similar patterns of seasonal changes in fish and trophic group assemblages while there may be between-method differences in species richness, total abundance, and trophic group abundances. The observed differences may be related to the longer sampling times of BRUV.
水下视觉普查(UVC)和诱饵远程水下视频(BRUV)是研究海洋和河口环境中鱼类组合的广泛使用的方法。本研究比较了BRUV和UVC方法评估波斯湾北部边缘礁珊瑚礁鱼类组合季节趋势的结果。为此,使用BRUV和UVC方法对珊瑚礁鱼类进行了季节性调查。对每种方法驱动的组合指标的比较表明,这两种方法可能揭示鱼类和营养组组合的季节变化模式相似,而方法之间在物种丰富度、总丰度和营养组丰度方面可能存在差异。观察到的差异可能与BRUV的较长采样时间有关。

This study was conducted to determine reproductive biology of Spotfin flathead Grammoplites suppositus for a period 16 months from November 2016 to April 2018 in coastal waters of the Persian Gulf. Sampling was carried out by shrimp bottom trawl net as bycatch and a total of 635 fish were examined during the study period. The recorded results showed that the sex ratio between male:female was not significantly being 1:1 throughout the study period with 55.28% of fish was female. Analysis of morphological maturity stages of ovary was showed that G. suppositus can spawn in throughout the year with a peak from November to March. Also, the GSI was uptrend in November to February and then declined from March in the region. The minimum size of the female G. suppositus that reaches the sexual maturity was observed in the size classes 160-179 mm of total length. The L m50 % was estimated at 199.4 mm of total length for this flathead fish.

In this research work, biology of Creole perch, Percichthys trucha, the largest top predator in the North Patagonia’s freshwater communities, in a deep oligotrophic lake in the region, focusing on (i) the differential use of littoral depth strata by age, (ii) age at maturity and spawning season and (iii) occurrence of reproductive migrations to vegetated shorelines has been described. Individuals from 12 locations within the lake were sampled and found that P. trucha makes differential use of the littoral zone through the year and through its life stages. From hatching and through their first year, juveniles prefer shallow vegetated littoral strata; 50% of the individuals have reached maturity at 1-year-old, and all are reproductive by 3-year-old. Overall, our results show that the reproductive behavior of P. trucha improves habitat connectivity between different zones of the lake and between the lake and other lakes connected to it by tributary streams.
在这项研究工作中,描述了北巴塔哥尼亚淡水群落中最大的顶级捕食者克里奥尔鲈鱼在该地区一个深度贫营养湖泊中的生物学,重点是(i)不同年龄对沿岸深层的不同利用,(ii)成熟期和产卵季节的年龄,以及(iii)向植被海岸线的繁殖迁移。对来自湖中12个地点的个体进行了采样,发现P.trucha在一年中及其生命阶段对沿岸带的利用不同。从孵化到第一年,幼鱼喜欢浅层植被的沿海地层;50%的个体在1岁时达到成熟,所有个体在3岁时都能繁殖。总的来说,我们的研究结果表明,P.trucha的繁殖行为改善了湖泊不同区域之间以及湖泊与其他通过支流连接的湖泊之间的栖息地连通性。

Overall, our results show that the reproductive behavior of P. trucha improves habitat connectivity between different zones of the lake and between the lake and other lakes connected to it by tributary streams.","PeriodicalId":14599,"journal":{"name":"Iranian Journal of Ichthyology","volume":"6 1","pages":"226-239"},"PeriodicalIF":0.0,"publicationDate":"2019-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44157447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of cartilaginous and osteological structures of the dorsal, anal and caudal fins, and axial skeleton in Nile tilapia ( Oreochromis niloticus ) was studied under three temperature treatments (22, 28 and 34oC). Fish samples were collected periodically during the developmental stage from hatching up to 39 days post hatching. Bone and cartilage development were evaluated. The results showed that the pattern and sequence of development and appearance of these elements in the three treatments are similar, and the difference is in timing of appearance and ossification of skeletal elements. Samples from 34oC started and ended bone formation earlier, but these process in 22oC treatment was very late. The temperature on the onset and end of chondrogenesis and ossification had a profound effect; these effects on 22oC treatment were severe than other treatments. The sequences of the chondrogenesis and ossification process was well conserved at all temperature treatments.
研究了尼罗罗非鱼(Oreochromis niloticus)背鳍、肛鳍、尾鳍和轴骨软骨和骨结构在22、28和34℃三种温度下的发育情况。在孵化至孵化后39天的发育阶段,定期采集鱼类样本。评估骨和软骨的发育情况。结果表明,三种处理中这些骨骼元素的发育和出现的模式和顺序相似,不同的是骨骼元素出现和骨化的时间。34℃处理的样品开始和结束骨形成的时间较早,但22℃处理的这一过程非常晚。温度对软骨形成和骨化的发生和结束有深远的影响;22℃处理的这些影响比其他处理严重。在所有温度处理下,软骨形成和骨化过程的序列都很好地保守。

For decades, the Mediterranean Sea received many invasive marine biota, which found their corridors to the Mediterranean environment through various ways, benefiting from the climate changes. On March 2019, a field trip was performed in the marine waters facing Banyas city, Syria, a specimen of the spotfin cardinal fish Jaydia queketti (Gilchrist, 1903) was caught. This record fills the gap in the species distribution along the eastern Mediterranean; between northern (Iskenderun Bay) and southern (Ashdod) coasts, and it is considered as the first report of this fish in the Syrian marine waters.
几十年来,地中海接纳了许多入侵的海洋生物,它们通过各种方式找到了通往地中海环境的走廊,受益于气候变化。2019年3月,在叙利亚班亚斯市的海洋水域进行实地考察时,捕获了一种斑点鳍红衣主教鱼Jaydia queketti (Gilchrist, 1903年)的标本。这一记录填补了东地中海沿岸物种分布的空白;在北部(伊斯肯德伦湾)和南部(阿什杜德)海岸之间,它被认为是叙利亚海洋水域中首次报道的这种鱼。
