The new species is distinguished from its congeners by the following combination of characters: posterior chamber of swim bladder developed, ovoid, directly connects to the anterior chamber; intestine short, zigzag-shaped and with two loops; lower jaw spoon-like, blunt, and covered by lips; snout length shorter than postorbital length; dorsal fin origin anterior to the ventral fin origin, and it closer to caudal fin base than tip of snout; the pelvic origin is just below vertical from the second branched dorsal fin ray, and tips of ventral fin reaching to anus or close to anal fin origin; vertebrae 4 + 36–38; gill rakers 10–11. Molecular phylogenetic analysis indicated that the new species is situated in the most basal of the genus Triplophysa species distributed in the Himalayan region of China. The Kimura’s 2-parameter interspecific genetic distance of the cytochrome b gene sequences of the new species differed from 5.6 to 20.3% with other Triplophysa species. Two non-native species, T. dalaica and T. scleroptera, were first found in the the Yarlung Tsangpo River, which would bring the number of Triplophysa in the Tibetan Himalaya of China to eleven species. A checklist of genus Triplophysa in Chinese Himalaya was further provided.","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139772992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Otolith abnormalities are associated with the partial replacement of aragonite (the usual otolithic polymorph of CaCO3) by vaterite (another less stable crystalline modification of CaCO3) and their unusual shape. The abnormalities are observed in 11.9% of the specimens and may be induced by technogenic pollution from Nornickel, the world’s largest manufacturer of palladium, nickel, and platinum. The assessment of bilateral asymmetry based on otolith measurements and shape indices does not indicate notable differences in this parameter between the charr forms. However, the shapes of the left and right otoliths described by wavelet analysis are significantly different in two groups: a form of Lake Kapchuk designated as the main form and F1 hybrids. The differentiation of the forms is evaluated using wavelet and linear discriminant analyses of otolith shape. The difference in the topologies of two dendrograms constructed based on the shapes of the left and right otoliths obtained from the same specimens can be explained by the occurrence of bilateral asymmetry.","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139773230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The COI gene sequence and phylogenetic analysis confirmed that Monotaxis heterodon and Monotaxis grandoculis were genetically distinct species and conform the distribution of M. heterodon in Indian Exclusive Economic Zone. In addition, molecular analysis using partial mitochondrial COI gene suggests that genetic distance within M. heterodon group was 0.32% of group mean distance between M. heterodon and M. grandoculis was 8.37%.

According to the materials of studies conducted in 2018–2022, the occurrence of the species in catches in the Mekong Delta averaged 20.7%, the proportion in terms of abundance was 2.6%, in terms of weight, 0.6%. The maximum values of the species parameters were 81.2 ind./effort and 176.2 g/effort, respectively. The abundance of fish significantly decreased in the conditions of low content of dissolved oxygen and on a substrate with plant residues. The sex ratio of T. tsukawakii was 1.0 : 3.1 with a stable prevalence of females, which distinguishes the species from other representatives of the family. Females have larger sizes compared to males and they gain weight faster. The fecundity of the species was determined for the first time; the average number of mature oocytes was 2950 psc. During a low-water period, callanoid copepods of the family Pseudodiaptomidae mainly represented by Pseudodiaptomus dauglishi Sewell, 1932 were the main food items of T. tsukawakii.

The maximum coefficient of variation was observed for inter-orbital length (25.85%) followed by lower jaw length (18.14%) and pectoral-fin length (16.96%). The morphometric index value was found <10% (genetically-controlled characters) for all the morphometric characters except total length with caudal filament length indicating restricted distribution. LLRs revealed isometric growth and high values of correlation coefficient (0.6109–0.9992). The b value of LWRs showed significant departure from 3 (p < 0.05) and hence negative allometric growth was recorded. The high R2 value of the LWRs indicates absolute fitness of the growth model and superior health status of the studied species. The mean condition factor value was calculated as 0.99 ± 0.04 indicating that the F. petimba population is in good health. Further, F. petimba is a reef-associated species forming a part of low-value bycatch which is mainly utilized for the preparation of fishmeal. Thus the provided morphometric and biometric information of the species will be useful for further biological, stock assessment and nutritional research in the region.","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139066860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
