Although this species is categorized as LC according to the IUCN Red List, it is rarely reported in fish inventories, with few specimens sampled. Moreover, data on the geographic distribution, population size, and other population details of M. notophthalmus are scarce and insufficient to predict possible threats and propose appropriate conservation measures and policies. A single specimen of Mastacembelus was collected using a fish trap on 20 February 2023, in a swamp, located in the middle course of the Lenggang River, Belitung Island, Indonesia. This specimen was identified as M. notophthalmus and this finding constitutes the southernmost record for this species, expanding its geographic range. In addition, the new record site is about 700 km south-east of the nearest locality in Peninsular Malaysia, about 250 km south-east of the nearest locality in Bangka Island, about 600 km south-east of the nearest locality in Sumatra, and about 500 km south-west from the nearest locality in Borneo. Better ecological and biological data concerning distribution, habitat, and stressors is crucial to reassess the conservation status of M. notophthalmus, and possible future conservation measures and policies. Therefore, we emphasize here the urgency for more comprehensive and accurate data to facilitate conservation assessments and management in Indonesia.","PeriodicalId":6950,"journal":{"name":"Acta Ichthyologica Et Piscatoria","volume":"1 1","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42083104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study provides comprehensive new data on parasites of the black-striped pipefish in Ukraine, with supporting data on its newly acquired freshwater range.

It was characterized by black posterior margins of the preopercle and opercle and black upper and lower lobes of the caudal fin. A specimen of this species collected from Munseom was distinguished from Chromis xanthura (Bleeker, 1854) based on distinct differences in the tips of the upper and lower caudal fin lobes, which are not black in C. xanthura. In addition, C. weberi was easily distinguished from the other four species in the genus Chromis, by the mitochondrial DNA cytochrome c oxidase subunit I gene sequence (345 bp), with genetic distances ranging from 0.130 to 0.252. This study documents the first record of C. weberi in temperate Korean waters, implying a poleward range expansion for this species.

The mesh size of 19 mm seems more appropriate for red mullet, surmullet, and blotched picarel, the mesh size of 22 mm for annular seabream and round sardinella, while for European hake and black scorpionfish, the mesh size larger than 26 mm would be more appropriate.","PeriodicalId":6950,"journal":{"name":"Acta Ichthyologica Et Piscatoria","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47648011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Malformations have been observed in species of the order Siluriformes, including the family Ariidae. In this study, we report malformations in the blue sea catfish, Ariopsis guatemalensis (Günther, 1864), and the tete sea catfish, Ariopsis seemanni (Günther, 1864), collected in San Blas, Mexico. The malformations include missing eye, cleft lip, and malformed barbels. Such malformations could be blamed on substantial levels of pesticides in the environment, genetic factors, and/or a pathogenic effect of some parasites specific to the studied fish species.","PeriodicalId":6950,"journal":{"name":"Acta Ichthyologica Et Piscatoria","volume":" ","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43461488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
