Coexistence of Two Closely Related Cyprinid Fishes (Hemiculter Bleekeri and Hemiculter Leucisculus) in the Upper Yangtze River, China

In this study, we investigated the mechanism by which two small cyprinid fishes (H. leucisculus and H. bleekeri) coexist by analyzing their niche segregation and morphological differences in the upper Yangtze River. Morphological analysis indicated that H. leucisculus has posteriorly located dorsal fins, whereas H. bleekeri has a more slender body, bigger eyes, longer anal fin base, and a higher head. Niche segregation analysis showed spatial and trophic niche segregation between these two species: on the spatial scale, H. leucisculus was more widely distributed than H. bleekeri, indicating that H. leucisculus is more of a generalist in the spatial dimension; on the trophic scale, H. bleekeri had a wider niche than H. leucisculus. Therefore, these two species adopt different adaptation mechanisms to coexist Keywords: biodiversity; species coexistence; spatial niche segregation; trophic niche segregation; morphology 1. -

However, little is known of its reproductive information regarding spawning pattern and season that could possibly explain its success as an invasive species. This research is the first presentation of its reproductive characteristics, which was conducted based on 235 individuals collected monthly throughout a year from Sefid River, in the southern Caspian Sea basin. Age, sex ratio, fecundity, oocytes diameter and gonado-somatic index were calculated. Regression analyses were used to find relations among fecundity and fish size, gonad weight (Wg) and age. The mature males and females were longer than 93.0 and 99.7mm in total length, respectively (+1 in age). The average egg diameter ranged from 0.4mm (April) to 1.1mm (August). Spawning took place in August, when the water temperature was 23 to 26°C. -

E-mail: [email protected] Abstract Pseudobagrus fui Miao is a valid bagrid species that can be separated from all its congeners in having 27–33 anal-fin rays. Among the species of Pseudobagrus, it forms part of a group of approximately 20 species putatively characterized by having a smooth anterior margin of the pectoral-fin spine and short maxillary barbels not extending to the base of the pectoral-fin spine. Pseudobagrus fui, together with P. nitidus and P. vachelli, can be differentiated from all other fork- tailed species of this group by having no fewer than 20 branched anal-fin rays, the posterior end of the anal-fin base posterior to the vertical through the posterior end of the adipose-fin base, and anal-fin base longer than the adipose-fin base. It further differs from P. nitidus in having a gas bladder without beaded lateral and posterior margins, and from P. -
18 State Institution for Plant Protection and Plant Quarantine, His Work On
state institution for plant protection and plant quarantine, his work on aquatic fauna was largely private. However, political restraints in the German Democratic Republic (DDR) permitted no open contacts with colleagues in countries of the Klassenfeind; field work was possible only in socialistic brother states. Among other activities, Dietrich Braasch and his friend, the late Dr. Wolfgang Joost, collected repeatedly in Bulgaria and published a series of faunistic and taxonomic studies on the stoneflies of the country, including descriptions of several new species. The collections of D. Braasch and W. Joost include important stonefly material. The material of Wolfgang Joost is deposited in the Museum der Natur, Gotha, Germany (Perla 23, 2005: 43-48), that of Dietrich Braasch is now in the Museum für Naturkunde, Berlin, Germany. I am grateful to Dr. Wolfram Mey for informing me of the recent transfer. This transfer came to my knowledge immediately before the closing deadline of the present issue of PERLA. Therefore, I refer to published bibliographies of Dietrich Braasch. The laudation at the occasion of his 65th birthday (Joost and Klausnitzer, 1997) lists all 210 publications published at that time, numbers 211-253 are presented by Mey (2016).

Our results indicated that Hemiculter leucisculus populations in China were clearly divided into two groups. The first group (Group 1) included the populations of the Yangtze River and its surrounding areas (including the Qiantangjiang, Lingjiang, Jiulongjiang, and Minjiang rivers); the second group (Group 2) contained local populations from southern China (including the Nanliujiang, Zhujiang, Wanquanhe, Qianjiang, and Nandujiang rivers). The Korean Hemiculter eigenmanni differed in its cytochrome b gene sequence by 0.6-1.0% from the Chinese H. leucisculus (Group 1), which inhabited the Yangtze River and its surrounding areas, suggesting they were phylogenetically close and likely to be the same species. The Korean H. leucisculus differed from the Chinese H. leucisculus (both Groups 1 and 2) by 8.1-9.5%, indicating a very distant phylogenetic relationship; however, the Korean H. leucisculus differed from Hemiculter bleekeri by only 0.5-0.7%, showing intraspecific nucleotide differences. We conclude that the taxonomic relationship between the Korean H. -
Species Diversity of Drifting Fish Eggs in the Yangtze River Using Molecular Identification
Species diversity of drifting fish eggs in the Yangtze River using molecular identification Mingdian Liu*, Dengqiang Wang*, Lei Gao, Huiwu Tian, Shaoping Liu, Daqing Chen and Xinbin Duan Yangtze River Fisheries Research Institute of Chinese Academy of Fishery Science, Wuhan, Hubei, China * These authors contributed equally to this work. ABSTRACT The dam constructions greatly changed the hydrologic conditions in the Yangtze River, and then significantly affected the spawning activities of indigenous river fish. Monitoring the species composition of drifting eggs during spawning season is important for protection issues. In this study, we have sampled drifting fish eggs in nine locations from 2014 to 2016. Eggs were identified using the mitochondrial cyt b gene sequence. A total of 7,933 fish eggs were sequenced successfully and blasted into the NCBI database. Thirty-nine fish species were identified, and were assigned to four families and two orders. Approximately 64% of the species identified, and 67% of the eggs, were classified in the Family Cyprinidae. Abundance and Shannon– Wiener diversity index of species were higher in the main river than in tributaries of the river. However, tributaries may be important spawning grounds for some fish species. The Jaccard's similarity index and river-way distances among sampled stations were negatively correlated suggesting the environment shapes species composition in the sampled spawning grounds. These results showed that mitochondrial DNA sequence is a powerful and effective tool for fish egg -
