In this article, we aimed to expand on the cytogenetic data available for Sturisoma, contributing to the record of the karyotype and other chromosomal characteristics of both minor and major ribosomal DNA of S. barbatum from the upper Paraguay River basin. This population had diploid chromosome number 66, a karyotype composed of 20 metacentric, 14 submetacentric, 14 subtelocentric, and 18 acrocentric chromosomes, and a fundamental number of 114 for both sexes. Heterochromatic regions were observed in the short arms of the nucleolus organizer regions (NOR)-bearing chromosome pair. Fluorescence in situ hybridization revealed a single 18S site and multiple 5S ribosomal DNA sites. Data from NORs confirmed the tendency of this family to present simple NORs sites, as well as multiple sites of 5S ribosomal DNA. Pericentric inversions (or other types of centromeric shift) and/or deletions appear essential in the karyotype evolution and differentiation among S. barbatum. The present data are valuable to help in understanding karyotypic evolution in Loricariidae.","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140316250","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}

In barbs inhabiting other lakes, where only a generalized form is found, the lack of such cluster is observed, while the eigenvector loadings on the second principal component generate a cluster similar in composition. The same pattern is discovered in the Altai osmans (genus Oreoleuciscus) in Lake Orog within the Central Asian Closed Basin (Mongolia). In this case, however, the specimens of the generalized form tend to exhibit the characters of a bigmouth form after transition to feeding on fish whereas the progeny of bigmouth barbs in Lake Tana exhibit the parental characters even in the aquarium-based experiments. It is assumed that in the Altai osmans from Lake Orog we observe an early stage of morpho-ecological divergence between forms, when it is still reversible, while the divergence at a later stage, when it is irreversible, is detected in the barbs from Lake Tana, which may be regarded as an example of genetic assimilation.","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140302205","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 almost triangular rear part of the brain capsule and a narrow posterior region of the neurocranium represent the border of the suprabranchial chamber. The pars superior of the inner ear is located along the internal triangular part of the brain capsule, and both crus communis and ductus semicircularis posterior are located close to each other in the narrow extreme rear region of the brain capsule. The sacculus is enclosed in the large oval bony capsule (saccular swelling), and the sagitta is large with the average otolith length–total body length (TL) ratio equal to 0.06. Linear growth of the lapillus and sagitta is characterized by negative allometry in relation to body length. Despite the slow growth rate of the lapillus, its shape substantially changes during the growth of the fish 36–205 mm TL that, most likely, reflects increasing locomotion complexity.

All fish have one nostril, olfactory rosette of the arrow-shaped type with no secondary folding on olfactory lamellae, and two ventilation sacs (ethmoidal and larger lacrimal). The rosette is located on the medial (A. clarkii and A. perideraion) or ventromedial (A. polymnus, A. frenatus, and A. ocellaris) sides of the olfactory cavity; the number of lamellae in the rosette increases as a fish grows. The greatest total number of lamellae is 24 in A. polymnus. Intercalary (in four species) and dichotomous (in three species) lamellae are found in the rosette of most anemonefishes, which is an extremely rare case in other fishes. Atypical lamellae emerge later than regular ones in the ontogeny of the fish, but their number in different parts of the rosette differs between anemonefishes, and in some A. polymnus species, lamellae are predominantly atypical. The slope of the medial and lateral sides of the rosette toward the openings of the ventilation sacs (A. polymnus and A. frenatus) is considered a structural adaptation that improves water exchange near the surface of the olfactory lamellae and reception of odor information by the fish. The relationship between the structure of the olfactory organ and the generality of anemonefishes, their specialization, and strength of association with symbiotic sea anemones has not been revealed. The idea of an evolutionary trend from a simple structure of the olfactory organ (A. clarkii) to a morphologically more complex structure (A. polymnus and A. frenatus) in the genus Amphiprion after early separation from the general stem of the subgenus Actinicola (A. ocellaris and A. percula) is presented.","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140302090","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 individual was found in the catch of a bottom trap installed at a depth of 24 m. The specimen with a total body length of 30.6 cm and a weight of 213.5 g was a sexually mature 3 years old male. According to the results of back-calculations obtained during the analysis of the otolith section, the individual growth of the caught fish occurred as follows: the total length was 17.7, 25.5, and 30.6 cm by the end of the first, second, and third years of life, respectively. No food items have been found in the gastrointestinal tract of the caught specimen. The geographical variability of the hake life cycle is considered. The species reaches its maximum size and age at high latitudes and at low water temperatures. Presumably, the maximum size and age of the hake in the Black Sea may be slightly higher than in the Mediterranean Sea, but lower than in the Northeast Atlantic. The prospects for further resettlement and increase in the number of the hake in the Black Sea are analyzed. Apparently, low salinity and competition with the native ichthyofauna may prevent successful naturalization of the species. However, the continuation of the trend of increasing salinity of the Black Sea under warming conditions will increase the possibilities of the hake naturalization.","PeriodicalId":48537,"journal":{"name":"Journal of Ichthyology","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2024-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140302086","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}
